Lexus LS VS Porsche Panamera
- Sumptuous luxury for the price
- Impressive efficiency/performance balance
- Excellent comfort and refinement
- Styling looking a little dated
- Multimedia system too downmarket and also looking dated
- A bit more driver involvement would be terrific
- Engineered like a Porsche
- Cool interior design
- Dynamic quality
- Remote steering
- Real-world fuel economy
- Expected safety tech optional
Lexus is returning to its roots and playing to traditional strengths with the 2021 LS update, as the Japanese luxury brand braces itself for the imminent release of an all-new Mercedes-Benz S-Class.
On sale now from $195,953 before on-road costs, the facelift ushers in a raft of comfort, refinement, driveability and technological upgrades, striving to deliver the quietest and most luxurious experience in the upper luxury sedan segment.
The blink-and-you'll-miss-it makeover runs to redesigned headlights, wheels, bumpers and tail-light lenses, as well as the inevitable multimedia screen update, improved seating revised trim and better safety.
Along with an all-in equipment list and unparalleled levels of ownership benefits, the goal is to emulate the dramatic differences that existed between the LS and its mostly German competition more than 30 years ago, which helped make Lexus a disruptor, decades before the term was even coined.
The MY21 range will continue offering two grades – the racier F Sport and opulent Sports Luxury – in either V6 twin-turbo petrol LS 500 or V6 petrol-electric hybrid LS 500h powertrain choices, as per the XF50-generation's Australian debut back in late 2017.
The question is: has Lexus gone far enough with its limousine flagship?
|Fuel Type||Hybrid with Premium Unleaded|
For Porsche purists, the arrival of the Cayenne SUV in the early noughties was a knife to the heart. Jaws dropped and minds blew at the thought of the brand’s famous crest being applied to the nose of a high-riding family truckster.
Although Porsche had previously toyed with the idea of a four-door sports/GT mash-up, this was for real; the idea being to push the brand’s performance reputation into the ‘executive’ space, and trim some Audi A8, BMW 7 Series and Merc S-Class grass.
To rub salt into that Porscheophile chest wound, the Panamera has fulfilled its brief, splintering into an ever-increasing range of niche variants, and last year evolving into a sleek, second-generation version.
And just when old-school 911 diehards thought it couldn’t get any weirder, the Panamera E-Hybrid arrived to turn their upside-down worlds inside-out.
In the model we’re looking at here, the Panamera 4 E-Hybrid, a 2.9-litre twin-turbo V6 petrol engine (in the nose), is supported by an electric motor (just behind it), which, according to Porsche, mimics the hybrid set-up used in its 918 Spyder hypercar.
You can't beat a lofty comparison. But is it a case of legitimate tech sharing for maximum efficiency and performance, or is it, in fact, just too big a stretch for a thumping, 2.2-tonne sports limo? Read on to find out.
|Engine Type||2.9L turbo|
|Fuel Type||Hybrid with Premium Unleaded|
One might be surprised to learn that, without having driven the latest S-Class, rival large luxury sedans have struggled to juggle comfort and refinement with agility and speed. Even in this modern age of adaptive dampers and air suspension. The Germans, in particular, seem to struggle at times.
The latest Lexus LS, however, walks the line with impressive confidence and poise, prioritising the former yet without dropping the ball with the latter. Just keep in mind that the 500h Sports Luxury manages the balance best.
The bar may just about be raised with the bestselling Stuttgart's arrival from March, but even then, with its extensive and complete specification, outstanding hybrid efficiency/performance combination and remarkable build quality and presentation, Japan's master luxury sedan deserves to find more buyers in this country.
Well done, Lexus.
The Porsche Panamera 4 E-Hybrid offers an interesting alternative to the traditional inhabitants of the upper-luxury sedan market. It’s quick, sleek and beautifully engineered. But it ultimately sits between two worlds rather than embracing both. An ‘individual’ choice that's not quite the fast GT you'd like it to be, nor the full-blown upper-luxury limo.
Is the high-tech Porsche Panamera 4 E-Hybrid your type of luxury GT? Tell us what you think in the comments below.
The XF50 series is a long and imposing machine, but is also arguably the most Toyota-looking LS in history, sharing design cues with most larger sedans the company builds – and yes, even the Camry. This is a departure from the Mercedes aping ‘90s and '00 generations. If the latest S-Class can look like a 200 per cent enlarged CLA, why not?
The most obvious – and pleasing – changes are realised when the headlights are switched on, revealing the BladeScan tech. In the F Sport, the redesigned bumpers' air intakes are noticeably larger and have jazzier pattern inserts, as part of a broader exercise in differentiating the grades with what's perceived as ‘sportier' elements throughout the car. The divisive ‘Spindle' grille theme remains.
Out back – arguably the most Toyota-esque part of the LS – are piano black tail-light inserts to differentiate new from old.
If Lexus is about presenting nuanced styling evolution as to not spook the demographic, then the MY21 flagship sedan succeeds brilliantly.
The first-generation Panamera’s famously awkward profile reflected then Porsche CEO, Wendelin Wiedeking’s demand that its rear seat should be able to accommodate his lanky frame.
Since then, saner (and presumably lower) heads have prevailed, with the sleeker, sportier second-gen version fitting more easily into the sleek and slick Porsche-design mould.
Hints of the iconic 911 abound, from the turret’s smooth curve towards the rear, to the distinctive tail-lights, recognisable headlights and familiar nose treatment.
Screaming green brake calipers reinforce the eco-friendly message, as does a green halo around the ‘Panamera 4’ badge on the tail, and ‘e-hybrid’ labels on the front doors.
Optional 21-inch ‘Panamera SportDesign’ wheels, finished in high-gloss black, ($9380) replace the standard 19-inch rims to give our test car a more menacing and purposeful look.
The interior-design theme is shaped by a similar set of traditional elements. including the iconic five-dial main instrument cluster (with tacho in the centre), chunky sports steering wheel, and chrono clock on the dashtop. The leather-trimmed sports seats (front and rear) feature a high, one-piece backrest, echoing those of Porsches past and present.
Not so familiar is the flight-deck-style dash, including a 12.3-inch high-res touchscreen media display, and maxi-size centre console housing touch-sensitive switchgear in place of Porsche’s usual array of knobs and buttons.
Rear-seat passengers are presented with an ultra-slick touchscreen display, integrated into the extended centre console, to manage their climate control, nav and media settings.
The optional ambient-lighting package ($990) fitted to our test car added a subtle green keyline glow to the door speaker surrounds front and rear.
Overall, the design manages to successfully combine slick luxury and comfort with clear sporting intent.
This is more like it.
While nowhere near the apex of striking interior design, with a dashboard that – again – is quite clearly from the contemporary Toyota way of thinking, the LS is massive inside, heaving with standard luxury and obsessively crafted in a few key touchpoint areas.
The brand makes a big noise about the floating door-sited armrests and their very obviously expensive craftspersonship, but it is eye-catching and satisfying to drink in the detailing, extending in and around into the dash seamlessly, carrying on the flowing, salubrious themes of sculptured multi-dimensional shapes. In 1989 journos were handing out similar platitudes in the original LS.
If the techno-overload of a Mercedes MBUX or Tesla's OTT tablet leave you cold, this enhances the luxury experience by adding a rich, cosy, warm ambience – though the instrumentation binnacle is familiar; all we can see is the first IS 250 of 1999, complete with its single, watch-face inspired analogue dial.
Here, of course, it's digitised and multi-configurable to accommodate sat-nav, multimedia and other vehicle-related needs, but it is a oddly nostalgic, given the brand's first BMW 3 Series rival is now almost forgotten. Still, it's interesting and isn't that what eccentric rich people who don't want to drive the cliché luxury behemoths desire?
With endless adjustability, the seats are sumptuous to the point of subsuming, in the way you'd imagine a limousine to be, but because of their bolstered support, they also can be manipulated into gently cupping you enough to stop you sliding about when throwing the Lexus about with gay abandon – more on that later on.
It doesn't need mentioning that the fit and finish is fabulous, with the enveloping luxury continuing out in the back seat. The Sport Luxury's airline-style recliners are enough to turn doubters into doe-eyed believers, with their restful, relaxing, relieving, refreshing and revitalising ways – well, to an extent that an airport massage-chair minus the coin box and dodgy stains can, in any case. But the fact remains: ensconced deep into that leather-lined luxury, slumber beckons. Namaste!
And that's the point of LS. It creates a sanctuary from the outside elements at least as effectively as Audi A8s, BMW 7s and Merc S' have costing upwards of 50 per cent more. The cabin is spacious, soothing and secure. On our extended drive of both 500 models, this was made abundantly clear with two stints behind the wheel of the visually similar ES 300h.
Quiet and refined, that car felt loud and coarse compared to the smooth silence of its supersized sibling. Mission accomplished, Lexus.
At just over 5m long, close to 2m wide, and a touch over 1.4m high, the Panamera is surprisingly close to the key dimensions of its traditionally supersized German competition - the Audi A8, BMW 7-Series, and Mercedes-Benz S-Class.
That said, its 2950mm wheelbase gives away a modest 42mm to the A8, a more substantial 85mm to the S-Class, and a lengthy 120mm to the 7 Series (all standard wheelbase versions). And this Porsche is strictly a four-seater, with elaborately sculpted and bolstered chairs for each occupant.
As you might expect, there’s plenty of room up front and generous storage space including a decent glove box, a lidded compartment between the seats, large door bins with space for bottles, and two cupholders (one jumbo, one regular) in the centre console.
In terms of power and ports there’s a 12-volt socket, USB plug (Apple CarPlay is standard), and an aux-in outlet.
The rear feels great, with ample head and legroom (for this 183cm tester), although getting in and out through a door aperture that tapers sharply towards the bottom is awkward. Not great for a car with limo aspirations.
A pair of longitudinally opening door lids in the centre console reveal a single cupholder and dual high-output USB power outlets. Our car also featured the ‘USB interface in rear’ option, at a measly $790!
A fold-down centre armrest opens to reveal a lined storage box, there are map pockets on the front seatbacks, and you’ll find bins (with bottle capacity) in the doors.
The back-seat section of the four-zone climate control system is run via the central touchscreen, with flashy knurled rollers to adjust temperature, and vents above the screen and in the back of the B-pillars to direct flow.
For an extra touch of luxury our test car featured an electric roller sunblind for the rear, and rear side windows ($2940).
The cargo compartment features four flip-up hooks to secure loads with a net or straps, a netted pocket on the passenger side, a 12-volt outlet and usefully bright lighting.
Boot space is 405 litres, enough to swallow our three-piece hard suitcase set (35, 68 and 105 litres) or the CarsGuide pram with room for soft bags to spare. The rear seat split-folds 60/40 to open up a whopping 1215 litres, and auto tailgate open/close is standard.
With no spare tyre; a repair kit is the only puncture option.
Price and features
Value, refinement and customer care are Lexus' traditional brand pillars.
Lexus broke through with recession-ravaged consumers at the dawn of the 1990s by firstly presenting an attractively conservative S-Class sized sedan at smaller E-Class prices, and then adding an uncannily hushed cabin of exquisite build quality, silky V8 performance, the entire kitchen sink of gadgetry and unheard-of ownership privileges, like tickets to events, free parking at selected venues and home/work vehicle pick-up at service time.
If such a strategy worked then, why not an expanded version now? After all, while sales started off slowly in Australia three decades ago, in the vital US market its impact was immense. Lexus eventually gained traction locally, but nowadays the LS lags significantly behind the leading S-Class; in 2020, it managed a three per cent share compared to Mercedes' 25.5 per cent – or just 18 registrations versus 163.
Sadly, the V8s haven't returned, but the facelift does bring a richer interior with high-quality materials to elevate comfort levels, backed up by redesigned seating and overhauled adaptive suspension dampers that also promote a cushier ride while not compromising steering/handling performance.
Meanwhile, new ambient lighting and (at last) touch-display capability for the 12.3-inch central screen and Apple CarPlay/Android Auto connectivity do at least play catch up with the rest of the industry, let alone its direct rivals.
The same applies with the fresh safety gains for the series that include a digital rear-view mirror, Lexus Connected Services (with automated collision notification, SOS call and vehicle tracking), Intersection Turning Assist (that helps keep the driver from turning into on-coming traffic or brakes the car if, whilst turning, a pedestrian crosses the road), far-broader functionality of the autonomous emergency braking systems (including greater rear-cross-traffic warning and intervention), full-speed stop/go adaptive cruise control with traffic flow capability, improved road-sign recognition, better lane-keep and assist tech and a next-gen adaptive high beam tech dubbed BladeScan with stronger lighting and anti-glare performance parameters.
These come on top of the standard adaptive dampers, height-adjustable rear air suspension, front/rear cross-traffic alert, sunroof, gesture-activated powered boot lid, soft-close doors, puddle lights, 23-speaker premium audio, digital radio, DVD player, head-up display, satellite navigation, climate control with infrared body temperature sensitivity, heated/vented front and rear outboard seating, powered seats with memory, heated steering wheel, electric rear blind and a four-camera surround-view monitor.
The F Sport from $195,953 differs from the Sport Luxury from $201,078 (both before on-road costs) with its 10 airbags, dark 20-inch alloys and exterior trim hues, brake-package boost, rear-wheel steering, variable gear ratio, unique instrumentation and dark-metallic interior themes and bolstered front seats, while the LS 500 adds active anti-roll bars front and rear.
Going Sports Luxury changes things up somewhat, with two extra airbags (rear-seat cushion items), special noise-reduced alloys, rear-zone climate control, Semi Aniline leather, a front-seat relaxation system, rear-seat tablet-style screens, powered reclinable heated/vented rear seats with ottoman and massage, rear centre armrest with touchscreen climate/multimedia control, side sunshades and – in LS 500 only – a rear cooler box.
On the owner-benefit front, ‘Encore Platinum' introduced last year builds on the regular Encore's valet servicing with benefits like free use of a Lexus for business or leisure travel within select Australian and now-New Zealand destinations (one-way only – sorry, Kiwis) for up to four times annually and lasting the first three years of ownership. There's also eight yearly free valet parking at certain shopping malls and other venues, several celebrity-laden social events/activities and discounted Caltex fuel.
With all these features as standard, the LS costs several tens of thousands of dollars less than most full-sized luxury sedan rivals with broadly similar performance outputs and optioned up with equivalent luxuries, before the Encore Premium privileges. However, while the Lexus' four-year/100,000km warranty also betters most competitors by one year, it is mileage capped while others' regimes aren't, and none beat Mercedes' five-year/unlimited program.
Though prices are up by nearly $2000, it's fair to conclude the extra kit and improvements help offset them, but it's also worth remembering that earlier last year, Lexus hiked LS prices by up to nearly $4000, and not too long before Encore Platinum was announced...
When you’re asking a whisker less than a quarter of a million dollars for a luxury performance car, it’s fair to expect a a healthy standard equipment list, and the Panamera 4 E-Hybrid satisfies that requirement.
Included in the $242,600 recommended retail price (before on-road costs) is four-zone climate control, 14-way electrically adjustable and heated front seats (with memory), a two-piece panoramic sunroof, multi-function sports steering wheel, adaptive cruise control, sat nav, adaptive air suspension, auto rear hatch, 19-inch alloy wheels, LED headlights, daytime running lights, tail-lights and indicators, auto headlights, keyless entry and start, leather trim, leather steering wheel, park assist and parking distance control (front and rear), rear privacy glass, rain-sensing wipers, and sat-nav.
As well as the nav, ventilation, phone and vehicle set-up, the 12.3-inch touchscreen multimedia interface controls the standard Bose 710-watt, 14-speaker audio (which adapts audio settings to ambient noise levels) with digital radio and Apple CarPlay.
Our test car was also loaded up with around 20 grand worth of options; specifically the 21-inch ‘Panamera SportDesign’ alloy wheels in high-gloss black ($9380), electric roller sunblind for rear compartment and rear side windows ($2940), ‘LED-Matrix’ headlights including ‘Porsche Dynamic Light System Plus’ ($2690), front-seat ventilation ($2190), ‘Lane Change Assist’ ($1890), ambient lighting ($990), rear USB interface ($790), and ‘Power Steering Plus’ ($650), for a before on-roads total of $264,120.
The tester’s ‘Carrara White Metallic’ finish is one of only two no-cost paint options.
Engine & trans
The LS is powered by two versions of a 3.5-litre V6 petrol engine.
Around 75 per cent of buyers choose the 500, which employs Lexus' V35A-FTS 3445cc double overhead cam 24-valve twin-turbo V6 petrol engine, delivering 310kW of power at 6000rpm and 600Nm of torque from 1600-4800rpm. Powering the rear wheels via an updated AGA0 10-speed torque-converter automatic transmission with driver-adaptive tech, it can reach 100km/h in 5.0 seconds flat, on the way to a 250km/h top speed.
For the facelift, it receives a revised twin-turbo set-up with reduced lag, new pistons and a lighter, one-piece aluminium intake manifold to save weight and cut noise paths while retaining existing outputs.
The 500h, meanwhile, gains software updates for more electrical assistance at lower revs for stronger acceleration times and feel. It employs the 8GR-FXS engine – a 3456cc naturally-aspirated variation with a higher compression ratio (13.0:1 versus the 500's 10.478:1), developing 220kW at 6600rpm and 350Nm at 5100rpm.
Being a series-parallel hybrid, there is a 132kW/300Nm permanent magnet motor and 650-system volt lithium-ion battery, making for a combined power output to 264kW. It now can run longer on pure electric – up to 129km/h compared with 70km/h before. Sending drive to the rear wheels via the L310 continuously variable transmission with a four-speed shift device and a 10-speed simulated shift control operation to mimic more natural auto responses, it requires 5.4s to hit 100km/h, and manages the same top speed as its 500 counterpart.
Both autos, by the way, have more aggressive Sport and Sport+ shift ratio software, while the M manual mode has paddle shifters.
Kerb weight varies from 2215kg (500 Sports Luxury) to 2340kg (500h Sports Luxury).
The Panamera 4 E-Hybrid is powered by a 2.9-litre, twin-turbo V6 petrol engine producing 243kW from 5250-6500rpm and 450 Nm from 1750-5000rpm, working in parallel with a ‘permanently excited’ synchronous electric motor delivering 100kW at 2800rpm and 400Nm from 100-2300rpm. And no, that 100rpm minimum figure for the motor’s maximum torque is not a typo.
They combine for a total output of 340kW at 6000rpm and 700Nm from just 1100-4500rpm, driving all four wheels, firstly, through an eight-speed dual-clutch auto transmission, and then Porsche’s active all-wheel drive system (with electronically variable, multi-plate clutch for torque distribution between front and rear axles).
Porsche claims 0-100km/h in 4.6sec in full parallel mode, and 0-60km/h (a useful urban performance measure) in 5.7sec, when running in pure EV mode.
The petrol V6 boasts the latest version of Porsche’s ‘VarioCam Plus’ variable cam timing, with the twin turbos located in the engine’s hot vee to minimise lag by creating the shortest possible path for exiting gases from exhaust, to turbo, to inlet.
Dubbed ‘PDK’ (Porsche DoppelKupplung), the Panamera’s eight-speed dual-clutch transmission is overdriven in its top three ratios, and wheel-mounted paddles spice up manual shifts.
The LS 500 returns a combined 10.0 litres per 100km, or 14.2L/100km urban and 7.6L/100km extra urban. Thus, the combined carbon dioxide emissions rating is 227 grams per kilometre, but can range from 172-321g/km. A theoretical average range of 820km is possible.
Moving on to the hybrid, the LS 500h manages a combined 6.6L/100km, or 7.8L/100km urban and an impressive 6.2L/100km extra urban. Its combined CO2, therefore, is 150g/km, and can drop as low as 142g/km and rise as high as 180g/km.
The Hybrid's average range should be about 1240km.
Both models require premium unleaded petrol as a minimum - 95 RON in the LS 500 and 98 RON in the Hybrid.
A key goal has been on reducing the stop/start frequency of the 500h's petrol engine during high-speed driving to increase both refinement and response.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is a miserly 2.5L/100km, emitting 56g/km of CO2 in the process. The electric motor consumes 15.9kWh/100km.
In the real world we averaged more than three times that at 8.3L/100km (at the bowser) over around 300km of mainly urban commuting, with some freeway running thrown in. And yes, we did indulge in some ‘Sport+’ enthusiasm to balance ‘E-Power’ austerity.
Recommended fuel is 98 RON premium, and you’ll need 80 litres of it to fill the tank.
Claimed pure electric range is roughly 50km (which we can verify), with a maximum velocity of 140km/h (which we can’t). Even with delicate use of the accelerator pedal my 48km (round trip) suburban commute was just too long for the Panamera’s pure electric range.
Luck out on a traffic-light-free route, or drop that urban crawl distance to 40km, and I reckon you’d be ‘there and back’ on a single overnight charge. The liquid-cooled lithium-ion battery pack takes 5.8 hours to charge via a conventional 240-volt/10amp outlet.
No matter what it says on the badge, the LS is first and foremost a large, heavy and imposing luxury sedan. Its sporting capabilities are relative.
Keeping that in mind, the updates for the MY21 version are a success, since the largest Lexus passenger car is uncannily quiet and refined, as you might hope and expect. The ride quality is largely cushioned and free of bump intrusion inside, with a sense of gliding over most road surfaces as if they were blemish-free.
We much prefer the Sport Luxury version, and the 500h in particular, because it can run silently in electric mode for periods, and somehow feels more lavish and plusher to ride in.
Whether that's psychosomatic or actual is debatable, for essentially both the 500 and Hybrid share the same multi-link front and rear platform, adaptive dampers and rear air suspension set-up, but the impression is that this grade is the choice for those wanting to feel ultimate luxury and peace.
On paper, the 500 F Sport should be the driver's choice, since it has the racier look and set-up, as well as 600Nm of tree-trunk-pulling torque.
The thing is, it doesn't necessarily feel all that athletic, and maybe that's because the whole existence of this model is based around isolating its occupants as comfortably as possible. This is no criticism, and the LS certainly envelopes everybody as a great limo ought to, but don't expect Audi S8 levels of steering crispness or handling agility.
Anyway, if you need to feel as if you are a princess in exile escaping villains with bazookas out the back of a Kombi, then the LS does an exceptional job in keeping the 2.3-tonne-plus mass in motion, cornering safely and precisely where it is pointed to, without losing too much composure or traction in tight, fast bends. This is quite a feat, really, for the big Lexus can be hurried along a mountain pass through narrow passages like a much smaller sedan, and without being bumped out of line or off course.
Again, for all-out performance, the 500h feels stronger, especially when called on to pull ahead instantly at speed, because the electric assistance is palpable compared to the regular 500's twin-turbo V6. Both are obviously very, very fast and sufficiently responsive to throttle inputs – and it's a sign of the brand's engineering prowess that their internal serenity means the speed isn't obvious until you're looking at the speedo – but there isn't even a whiff of lag in the Hybrid. That said, once on the go, that twin-turbo V6 in the 500 soars.
Considered in this context, you have to say that the MY21 LS is an exceptionally sumptuous and sophisticated limousine with the speed, safety, security and capability of taking you from point A to B without drama or noise.
Or, for that matter, excitement.
The first impression behind the Panamera’s wheel is mild claustrophobia, thanks to a high window line combined with our test car’s predominantly black interior. And if you’re a head-check lane changer you’ll find over-shoulder vision relatively tight and crowded.
Then there are the front seats - a graceful design with heaps of lateral support, but firm in the finest German tradition. Not quite as firm as the armrest though, which is so unforgiving I found it uncomfortable to use.
The E-Hybrid system operates in one of six modes, with the purely electric ‘E-Power’ set as the default from start-up. Not surprisingly, the 2170kg Panamera is quiet and relatively meek in this setting, while still offering enough performance for easy lane changes and reasonably swift overtakes.
‘Hybrid Auto’ switches between engine and motor with the aim of balancing power and efficiency, while ‘E-Hold’ conserves the current state of charge, allowing a switch to electric-only zero-emissions when desired (or possibly in future, when legally required).
In ‘E-Charge’ the V6 produces more power than it needs for driving to charge the battery as a side project, ‘Sport’ ensures battery charge is maintained at a minimum level so there’s sufficient reserve for an electric boost when needed. And as the name implies ‘Sport Plus’ delivers maximum (combined) performance, the engine recharging the battery as quickly as possible at the same time.
That final setting is where this Panamera starts to feel like a proper Porsche. The 2.9-litre V6 sounds gruff and builds to a satisfying bellow as revs rise, and if you get the bit between your teeth and pin the throttle, every one of those 700Nm make their presence felt.
Manual changes from the dual-clutch transmission are quick and positive, although we did experience a moment of alarming slow-speed paralysis where the PDK took its sweet time to cooperate and agree to move the car forward.
The alloy-rich suspension is a double-wishbone front, multi-link rear set-up, with the ‘Adaptive Chassis Control’ combining switchable, three-chamber air springs with adjustable dampers.
Ride comfort (even on the test car’s optional 21s shod with hi-po Pirelli P Zero rubber) is excellent, and the big Panamera remains balanced and buttoned down in quick cornering.
Brakes are substantial with six-piston calipers on 390mm (cast iron) ventilated rotors at the front, and four-piston units on 365mm vented rotors at the rear. Pedal feel is progressive and stopping power always professional grade.
But no matter which drive mode you’re in the ‘Power Steering Plus’ speed-sensitive, electrically assisted steering feels mediocre - overly light, with surprisingly modest feedback from the front wheels. And despite the car’s performance potential this limitation alone makes it hard to bond with the Panamera E-Hybrid as a performance partner.
Neither the ANCAP organisation nor Euro NCAP has crash-tested an LS for this or previous generations. And, for that matter, nor has the American NHTSA or IIHS, due to low sales.
Standard safety items include 10 to 12 airbags (depending on model, with dual front, front-side and curtain items), AEB with pedestrian and cyclist detection, forward collision warning, driver attention alert, Lane Keep Assist, a Front Lateral Side Pre-Collision System, Active Steering Assist, radar-based adaptive cruise control, Parking Support Brake, Road Sign Assist (detects certain speed signs), a four-camera Panoramic View Monitor, Blind Spot Monitor, Lexus Connected Services, Electronic Stability Control, traction control, anti-lock brakes with electronic brake-force distribution and brake-assist, and parking sensors all-round. The BladeScan adaptive LED headlights with anti-dazzle tech is also fitted.
The LS' AEB functions between 5km/h and 180km/h.
Additionally, two rear-seat ISOFIX points as well as three top tethers for straps are supplied.
A fast four-seater needs top-shelf active safety, and the Panamera E-Hybrid boasts front and rear park assist, and ‘Surround View’, as well as AEB (Auto Emergency Braking), ABS, BA (Brake Assist), ESC (Electronic Stability Control), traction control, a tyre-pressure-monitoring system, auto-levelling headlights and LED daytime running lights.
But things that should be standard in a $250k sports luxury limo are optional. For example, lane-keeping assist, lane-change assist, and Porsche’s ‘Night View Assist’ technology.
If a crash is unavoidable there are no less than 10 airbags located around the interior (dual front, driver and front passenger knee, front side, front thorax, and full-length curtain). There’s also an active bonnet to minimise pedestrian injury, as well as top tethers and ISOFIX anchors for child restraints in both rear-seat positions.
The Panamera hasn’t been assessed by ANCAP (or EuroNCAP).
Lexus offers a four-year 100,000km warranty, which is considered one of the worst in the industry for mileage distance, due to the low number. Most rivals offer unlimited kilometre warranties, as well as more years in some cases.
However, it does come with a three-year program covering standard logbook services completed at an authorised service centre, with the first three annual/15,000km services for the LS costing $595 apiece.
A complimentary pickup and return service from home or workplace is available, as are a loan car, exterior wash and an interior vacuum during servicing. It's all part of the Lexus Encore Owners Benefit program, offered for three years and includes 24/7 roadside assistance.
Finally, the Encore Platinum brings the aforementioned travel destination free Lexus vehicle program (four times a year over three years) in Australia and NZ, as well as numerous valet parking and events privileges, limited to a several annually, and discounted fuel at participating outlets.
Porsche offers a three year/unlimited km warranty, with three-year paint, and 12-year anti-corrosion cover. Twenty-four-hour roadside assist is included in the warranty, renewed every time you service the car at an authorised dealer.
The recommended service interval for the Panamera E-Hybrid is 12 months/15,000km, and Porsche doesn’t offer a capped-price-servicing program.
