Porsche Panamera VS Lexus GS
- Super-smooth V6
- Lots of interesting tech
- Lovely (if old-fashioned) interior
- Media system
- No Apple CarPlay/Android Auto
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|
Ah, yes, the Lexus GS. Toyota's luxury off-shoot had high hopes for the new big boy when I first saw it a few years ago. Not thousands-of-sales high hopes, but the company thought a rear-wheel drive luxury sedan stacked with gear you didn't even know you wanted would be a dead-set winner.
And to be fair, they were right. I ran a GS as a long-termer and it was impeccably-mannered. In hybrid form. It wasn't sparkling, but my goodness, it used barely any fuel; especially impressive given its size.
|Fuel Type||Premium Unleaded Petrol|
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.
Weirdly, given all the good things I've had to say about the GS F Sport, it doesn't quite hang together. It's missing that certain something the Europeans have in their chassis, particularly the BMW 5 Series, and with ageing interior tech, it's struggling to keep up.
It's a car built for specific tastes, and they're more California than Straya. And that's perfectly okay, but unfortunately, that doesn't translate to a stampede of buyers. Having said that, none of its German rivals (or its beleaguered Japanese counterpart, Infiniti) could claim wild sales success either.
The GS is a terrific car, underrated but also just not quite there for my taste. The GS F, though, that's another thing altogether.
Does Lexus even register on your big luxury sedan radar? If it does, what stops you from taking the plunge?
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.
The GS is ageing well, but it's still a bit heavy-handed around the headlights and a little on the slabby side along the flanks. It doesn't look poised for action, even with the F Sport additions, but nor does it look frumpy, mostly due to the whopping blacked-out spindle grille, a Lexus signature.
The rear end is good looking but a bit bluff, again neither surprising or delighting.
Little has changed inside, but it's still a very nice cabin, and always will be apart from a couple of clangers (the gear shifter looks super-cheap).
What's more, it's welcoming, lots of very nice materials, comfortable, seats - it's exactly what it needs to be. Whatever you might think of the looks, one thing is absolutely certain - if anyone builds cars better than Lexus, it's a very, very short list.
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.
Being a big car, there's plenty of room inside. Four passengers will be very comfortable although rear legroom was a bit on the skinny side given the car's size.
The cabin contains a good-sized console bin, four cupholders and each door pocket into which you could conceivably slot a bottle.
The 520-litre boot is a useful shape, with a sensible load height and a space-saver spare under the floor. The 5 Series and E Class both best the Lexus by 10 litres, so the GS isn't far off the norm.
Price and features
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.
We had the pleasure of the GS 350 F Sport for the week, which is well over $10,000 cheaper than the Luxury and is therefore the 'default. If you're not sure what F Sport means, it's Lexus' answer to an M Sport or AMG pack, without all the high-powered engine shenanigans to go with it. If that's what you're after, the V8-powered Lexus GS F is definitely for you.
Starting at $95,300, the F Sport has a spectacular standard features list - 17-speaker stereo, 19-inch alloys, variable-geared four-wheel steer (!), adaptive suspension, dual-zone climate control (with moisturising function), hectares of leather trim, head-up display, electrically-operated heated and ventilated front seats, rear sunshade, F Sport instrument screen, auto LED headlights, keyless entry and start, sat nav, front and rear parking sensors with around-view cameras and a space-saver spare.
The media system is run from Lexus' 12.3-inch screen embedded in the dashboard and controlled from an infuriating console-mounted mouse-clicker with a couple of shortcut buttons. It really is spectacularly irritating and made worse by the rotary dial stationed next to it that acts as the drive mode selector. Why not use that instead?
As ever, the system is mildly baffling to use and hard to look at, but the sound is absolutely lovely from the Mark Levinson-branded speakers. Lexus is persisting with a DVD player but it also has DAB+.
Engine & trans
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.
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.
A real world 13.7L/100km is a solid miss of the claimed 9.3L/100km, which itself is hardly earth-shattering. It's a big heavy car and that's the penalty. It drinks fuel fast, so the 66-litre fuel tank does drain quickly and it's worth knowing you have to fill it with the 95 RON or better.
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.
There are things you expect in a Lexus. Quietness. Composure. Smoothness. The GS delivers all three of those things effortlessly. But it has a few extra things in its bag that I can't say I was expecting.
For a start, the 3.5-litre V6 moves the car without any carry-on and in doing so, I was constantly amazed at how quickly the speed in the head-up display reached the posted limit. It just doesn't feel or sound like a six second car, but there you are. The transmission is virtually faultless, the engine sound distant and refined, the power impressive.
It's a heavy car, no question, but two things work to make it feel much lighter. First - and it doesn't matter which mode you choose - the adaptive suspension somehow knocks about 200kg out of how heavy the car feels. The brakes, while a little soft on pedal feel when you first step on them, are very effective and again help to make the car feel lighter than it is.
The four driving modes are quite distinct. As usual, Eco makes everything soft and doughy or as I prefer to say, unpleasant. Normal is great for every day, with just the right throttle response and steering weight.
Moving to sport ups the aggro slightly while Sport+, while never harsh, firms everything up to the point where it starts to feel like a different car. Sport+ makes the car feel race-car pointy, the suspension holds the body in check and the power seems readily available without jerky progression
The all-wheel steer is a big part of the change in feel. It's is especially sharp in Sport+ mode. The steering's gearing changes up quite a bit, meaning a lot less steering lock required for your favourite hairpin bend. Of course, at real speed it all calms down because neither you nor Lexus are fond of sneezy lane-changes or Armco-swiping. At first I thought it just made the big car feel a bit too nervous but as I got used to it (and was able to dial it down by switching back into a less racy mode) I found it fun but a little bit out of character with the car itself.
And just because it's the F Sport, that doesn't mean it can't do all the things you'd expect from a Lexus. You can still waft, you can still creep up on people and it's really very comfortable when you're cruising or stuck in traffic.
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).
The GS scores 10 airbags, ABS, stability and traction controls, blind spot monitoring, rear cross traffic alert, forward AEB, active cruise, auto high beams and lane departure warning with lane keep assist.
The GS doesn't have an ANCAP or Euro NCAP rating while the USA's IIHS (Insurance Institute for Highway Safety) rating is good for each key crash-worthiness measure. The IIHS suite of tests is quite rigorous but differ from our ANCAP/Euro NCAP standards.
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.
There's one area where Lexus smashes the Germans and that's after-sales. While the warranty is hardly ground-breaking at four years/100,000km and service intervals are reasonable at 12 months/15,000km, it's how it all comes together.
For the duration of the warranty, when the car needs a service, Lexus will either come and get it then return it to you, or give you a loan car. Anecdotal evidence suggests this continues long after the warranty runs out. Like, 10 years after the warranty runs out.
This is a small thing, but if there's one thing I hate about car ownership, it's the servicing experience. If I was a betting man, I'd dare you to find someone who genuinely has a problem with Lexus after-sales care.
On top of that, you get a generous roadside assist package for four years.
