Kia Ev4 vs Lexus LS500H (hybrid)

What's the difference?

An electric sedan is really shrinking the buyer pool, which is why Kia has such gentle expectations for the EV4 in Australia. But it's a lovely driving EV with plenty of perks, and the design alone will brighten up Australia's roadways. For my money, I'd either be going for the cheapest one that's sharp value with plenty of kit, or the flagship GT-Line that gets the big battery and the works in terms of equipment. The Earth for me sits in no-man's land.

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 slippery-looking unit that adorns this page is the EV4 sedan. There’s also a hatch, but it comes out of Europe, while this one comes out of Korea, and that would likely make the hatch far more expensive than this bad boy. It's under study, apparently, but yet to be confirmed.

Anyway, to steal a hackneyed football analogy, for mine this is a game of two halves. I actually really like the front end. It looks sleek and slippery and there’s a real presence from the swollen arches.

I am, however, a little less sold on this rear end, which looks sharp and blocky and almost like it has been bolted on. Also annoying is the fact that it looks like it should be a liftback, with the boot hinged up above the rear windscreen. But nope, it's hinged below it, so you still get a dinky little opening to squeeze your stuff through.

Kia's international designers are pushing the boat out at the moment, and they deserve credit for making things different. Whether it sinks or swims with the general public, though, will be the real test.

Inside, it's all pretty traditional Kia, with all three models sharing the twin 12.3-inch digital displays, along with the little climate panel in the middle. Kudos to Kia for keeping some physical buttons, too. I'm less sold on the use of some cheap, hard plastics, even in the top-spec cars.

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.

At 4730mm long, 1860mm wide and 1480mm tall, the EV4 sits between the Model 3 and the Seal in terms of its outright dimensions. Kia says the EV4's wheelbase and interior packaging has been designed to maximise backseat space, which I must admit, there is plenty of.

Sitting behind my own 175cm driving position, I had miles and miles of leg room, and enough head room, though there is some kind of optical illusion that occurs in the backseat of the EV4 – even though you definitely have enough space, the dark materials of the GT-Line still leaving me feeling a little claustrophobic somehow.

Something else not to be sneezed at is the inclusion of the household-style power plug in the back. My laptop died while I was taking notes on my test, and I plugged it straight in and powered it up. Super handy.

At the back, there is 490 litres of boot space, which is about middle ground. The Seal is more like 400 litres, but the Model 3 offers more.

Sadly the EV4 is yet another EV that does not have a spare wheel of any kind. Instead you have to make do with a tyre repair kit.

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.

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...

All EV4 models are front-wheel drive, with a single front-mounted motor producing 150kW and 283Nm, fed through a single-speed gearbox. That’s enough, Kia says, to knock off the sprint to 100km/h in around 7.5 seconds. The Air is the fastest, at 7.4s, while the heavier Earth and GT-Line claim 7.8s. Top speed is a claimed 170km/h.

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).

Let’s talk about range for a moment, because it's bloody impressive. Not quite the best out there, but the furthest any electric Kia has ever travelled between charges.

There are two battery options, a 58.3kWh NCM battery in the Standard Range, and a 81.4kWh unit in Long Range models. The Standard will deliver 456kms in driving range, but the Long Range ups that to 612kms, both on the WLTP cycle. 

The EV4’s 400-volt architecture does slow down charging a little, though, with DC fast charging capped at 128kW. That means going from 10 to 80 per cent in around 30 mins when using the fastest chargers. If you’re using a 50kW charger, it’s up to almost an hour and 20 minutes for the bigger battery, which is a long coffee stop.

Plugged in at home, provided you have an 11kW wallbox, it’ll take just under five and a half hours, or just over seven hours, to go from 10 per cent to fully charged, so an overnight charge no matter the battery size.

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.

I learned something new and exciting (well, to me, at least. You might be very bored) from Kia's ride and handling guru on this launch. And that is that the tuning frequency for common city road imperfections, like bridge expanders, is actually the same as for the bigger, bouncier undulations you get on country roads. And so you can tune to prioritise one or the other, not both.

In real terms, it means a car that feels custom-built for the city, gliding over urban roads with mega comfort (which is exactly what the EV4 does), feels slightly less at home out of town, where there is more obvious movement in the cabin.

Bored yet? Ok, the point is that, while never uncomfortable, the EV4 feels right at home in the city, which is where it's expected to spend most of its time, but weirdly firmer on longer adventures. 

This really is easy, city EV motoring, done well. There's no alienating floatiness to the ride, no lifeless lightness to the steering, it's comfortable, quiet and – despite no headline-grabbing power figures – more than potent enough to get you up and moving.

There's nice weight to the steering, and though the front tyres gave up their grip a couple of times when pushed with some steering lock on, there isn't much in the way of aggressive body roll, and it all feels pretty confidence inspiring. 

The power is most effective from around 10km/h to 80km/h, before the urgency starts to fall away – it's slower to respond at freeway speeds – but that too just leans into its city credentials.

There's really not much to complain about here. It feels well sorted, and quite fun to drive. There is nothing that really stands out as spectacular about the drive experience, but nor is there anything to complain about. It's just really solid motoring, which isn't always guaranteed these days.

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.

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.

Kia ownership proposition is simple, and pretty strong. You get a seven-year warranty no matter how far you travel, an eight-year warranty for the high-voltage systems, again no matter how far you travel, and capped-price servicing. Pre-paying your service costs will set you back $688 for three years, just over $1300 for five years, or just under $2000 for seven years.

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.
