Lexus LS500 vs BMW M8

What's the difference?

The LS500 is the least logical version of the most logical option in the ultimate luxury sedan segment in which logic doesn’t often apply at all. 

Take from that what you will, but if it was me being driven around I would definitely be opting for the hybrid version of the LS instead for its smooth electrified driving characteristics and lower operating costs.

With dramatic looks, a luxurious spec, and impeccable quality, the BMW M8 Competition Gran Coupe remains supremely well controlled as it delivers eye-widening performance and amazing dynamics. But there’s an ‘edge’ to the experience you need to be ready for. If I was determined to head for the Aussie ‘fast lane’ in a BMW 8 Series Gran Coupe I’d opt for the M850i and pocket a lazy $71K (enough for a cheeky M235i Gran Coupe to add to your collection).

The distinctive but conservative style of Lexus is on full show across the LS’s massive frame. Like other cars in its class, it’s very much the image of the brand itself with styling points strong, but to me not as impressive as the LC500, which is a definitive expression of the brand.

The LS also has many styling points of the previous-generation Lexus design language which are in the process of being phased out.

The car was only updated last year, bringing with it a more recent interpretation of the brand’s big spindle grille, pointy headlight profile, and angular but traditional rear.

The LS - even in this Sports Luxury guise - does look quite menacing from certain angles. The width and stance of this car is accentuated by its curvaceous rear guards and big square front bumper, with the elegance of a classic three-box sedan maintained in a side profile.

The chrome wheel finish is a bit much for my taste, but there’s no doubt they’re real show pieces. They’d better be, too, because I hear they are incredibly expensive should you need to replace one.

The inside has highs and lows but it’s the place where you can most tell the LS has been on sale for a while.

I love the plush seats, big screen, integrated analogue clock and three-dimensional door card design, which sell the flagship luxury feel.

But this car’s age is on show with its clunky and much maligned 'Remote Touch' pad controller (which Lexus is at long last phasing out in its new cars), last-generation software suite, and its small, crowded instrument cluster.

There are a whopping nine interior trim combinations to choose from and ours has the most recently added black leather and ‘Nishijin Haku’ themed highlights which are meant to be inspired by the way "moonlight sits on an open sea".

The feel is a bit '90s, a rough textured fabric with a silver detailing and elements clad in a thin platinum foil, making you feel like you’re in a classic high-class Japanese taxi.

But I’ll admit it plays well with the ambient lighting effect in the doors, and is a unique selling point compared to the standard leather finish.

Want to start a vigorous car enthusiast discussion (more a verbal punch-up)? Simply ask whether a four-door car can be a coupe.

Traditionally, the answer is no, but over time numerous automotive brands have applied that description to cars with more than two doors, including SUVs!

So, here we are. A four-door ‘Gran Coupe’, and the M8 Competition version retains the smoothly tapering turret and frameless side glass that help give selected BMW four-door models the same swoopy, coupe look.

At close to 4.9m long, a fraction over 1.9m wide, and under 1.4m high, the BMW 8 Series Gran Coupe has a firmly planted, low-slung, wide-track stance. Always a subjective call, but I for one, think it looks stunning, especially in our test car’s ‘Frozen Brilliant White’ matt paint finish.

In an era of comically oversized BMW grilles, things are relatively under control here, with a bright black finish applied to that ‘kidney grille’, as well as the huge front bumper air intakes, front splitter, front fender vents, exterior mirrors, window surrounds, 20-inch rims, lip spoiler on the boot, rear valance panel (incorporating a functional diffuser), and quad exhaust tips. The roof’s black, too, but that’s because it’s made of carbon-fibre.

Overall the M8 Competition Gran Coupe is a compelling combination of strong, confident character lines along the bonnet and lower flanks, with tightly wrapped curves following the high hip line, and more organically irregular, yet distinctly BMW shapes in the head- and tail-lights. 

The interior is a beautifully balanced design with a broad centre console sweeping up to the middle of the dash and wrapping around to focus on the driver, in typical BMW fashion.

 The multi-adjustable sports front seats are immaculate, with high-end quilting in the centre section matching a similar treatment in the doors. The dark grey (full) leather trim is offset by carbon and brushed metal trim elements for a cool, calm and focused feel.

Crack the bonnet open and a spectacular ‘BMW M Power’ carbon cover dressing the top of the engine is guaranteed to impress friends and family.

For passengers, as you’d expect, the LS is stellar. The massive outboard rear seats offer plenty of room, and are complete with reclining, message, and cooling functions.

Adjustable vents feature, with quad-zone climate, and the screens come with individual headphone jacks and HDMI-in so you can bring with you all sorts of entertainment options for those longer journeys.

Other suitable additions worth noting include the wine cooler (although it’s a bit small for anything other than minibar-sized beverages, hardly the 007 trope of rolling out a full-size bottle of Bollinger), flip-down mirror with a light in the roof, and the touch panel controls in the armrest. I also appreciate the built-in sunshades. Nice touch.

Less impressive is the general vibe of the middle seat. With a large raised centre split in the floor and such wide and lavish outboard seats, the middle seat feels a bit forgotten.

Up front, the practicality offering includes a high level of adjustability for the seats to suit a wide range of driving positions, electrical adjust even for the steering column, and a nice wide seat which you simply sink into.

Of course, soft finishes adorn even unseen parts of the cabin so you’ll never touch a nasty hard plastic, and there are large storage areas in both the doors and centre console box.

This big armrest console also hides the USB connectivity within, and there’s a set of big cup holders with a flip-away lid if you want the wood grain design uninterrupted when they are not in use.

I have to mention the useless touchpad controller here, but hand the brand props for offering a collection of climate shortcut buttons on the dash, an actual volume knob, and truth be told you don’t need the touchpad anyway because the screen is touch. Just be ready for the matching last-generation software, which isn’t the best to use or navigate.

The boot has a volume of 440 litres which sounds plentiful, but the actual use of it is a reminder of one of the reasons SUVs are so popular.

Yes, it’s big and reasonably deep, but putting the largest CarsGuide case in there proved a bit clumsy as you have to lift it over the tall rear bumper and it only just clears the top of the relatively small opening.

I love sedans, but this is one area where you can see the benefit of a hatch opening, particularly if you were frequently doing the airport run.

Of the M8 Competition Gran Coupe’s 4867mm overall length, 2827 of it sits between the front and rear axles, which is a pretty healthy wheelbase for a car this size (and 200mm more than the 8 Series two-door coupe).

Space up front is generous, and one upside of a four-door, rather than two-door coupe, is you’re not struggling quite so much for space to get in and out when parked next to other cars.

Once inside, there’s plenty of storage up front, with a large lidded box/armrest between the front seats, twin cupholders in the centre console, as well as another covered area for wireless phone charging and extra bits and pieces in front of that. Long door pockets provide space for bottles, and the glove box is a decent size. There’s 12V power as well as USB sockets for media connection, with charging outlets in support.

At first glance you’d swear the rear seat was designed as a two-seater only, but when push (literally) comes to shove a centre passenger can squeeze in, legs straddling the rear console.

In terms of legroom, at 183cm (6’0”) I could sit behind the driver’s seat set for my position with knee room to spare, but headroom is another matter, with my noggin making solid contact with the soft Alcantara headlining. It’s the price you pay for this car’s racy profile.

There’s a neatly trimmed storage box and two cupholders in the fold-down centre armrest, plus door pockets with enough room for small bottles. The rear console houses dual climate controls, twin USB power sockets, and a small oddments tray, as well as buttons for the optional rear seat heating fitted to our test car ($900).

The 440-litre boot is a bit like the car itself - long and wide, but not very high. The rear seat split-folds 40/20/40 if you need more space, and the boot lid is automatic with a hands free function. But don’t bother looking for a spare of any description, a tyre repair kit is your only option.

At $349,900, before on-road costs, the BMW M8 Competition Gran Coupe sits in an interesting part of the upper-luxury, high-performance market, the unifying theme being a forced induction V8 engine under the bonnet. 

On price, it lines up almost exactly with Bentley’s twin-turbo Continental GT V8 ($346,268), but that’s a more conventional, two-door coupe. 

If it’s four doors you’re after, some compelling options, within shouting distance of the M8’s price, include the supercharged V8 Jaguar XJR 575 ($309,380), twin-turbo V8 Maserati Quattroporte GTS GranSport ($299,990), and the presidentially powerful and imposing twin-turbo V8 Mercedes-AMG S 63 L ($392,835).

But, arguably, the competitor that lines up best in terms of intent, performance, and personality is Porsche’s Panamera GTS ($366,700). You guessed it, a twin-turbo V8, also designed to prowl the autobahn’s left lane. 

So, in this exalted company you need to bring your quality and features A-game, and the M8 Competition Gran Coupe doesn’t disappoint. 

Running through all the car’s standard equipment would be a tedious exercise, if only for the sheer volume of features, and hopefully, the following highlights package will give you a feel for the level we’re talking about here.

Aside from copious amounts of active and passive safety tech (covered in the Safety section) this brutal Beamer features, four-zone climate control, configurable ambient (interior) lighting, keyless entry and start, ‘Merino’ leather trim covering the seats, doors, dash, M steering wheel, and gearshift, ‘Anthracite’ Alcantara headlining, 20-inch alloy rims, active cruise control, a digital instrument panel, head-up display, and laser headlights.

The electrically-adjustable sports front seats are ventilated and heated, while the leather-trimmed steering wheel, front centre armrest, and even the front door armrests can also be dialled up to a toasty setting.

You can also add a 10.25-inch multimedia display featuring navigation (with real-time traffic updates), Apple CarPlay and Bluetooth connectivity, as well as gesture control and voice recognition. The exterior mirrors are heated, folding, and auto-dimming. The Bang & Olufsen surround sound audio system boasts 16 speakers and digital radio.   

There’s also a digital dash display, panoramic sunroof, rain-sensing wipers, soft-close doors, power sunblinds on the rear, and rear side windows, and a l-o-t more. Even in this price range, that standard fit-out is impressive.

The LS500 packs a 3.4-litre twin-turbocharged V6 petrol engine with impressive peak outputs of 310kW/600Nm.

This engine is designed to replace a V8 in terms of its power and feel, and in a lot of ways it does.

It might surprise you to learn the only other place you’ll see this engine used in Australia is the Toyota LandCruiser 300 Series.

The alternative present in the LS500h is a hybrid version of the same engine, sans the turbos.

With its electric assistance, power outputs are lower than this turbo version, but get close with a combined total of 264kW.

While I like the walloping nature of the turbocharged V6 we drove, I think the hybrid is a no-brainer choice for reasons explained in the driving segment.

The M8 Competition is powered by an all-alloy, 4.4-litre twin-turbo V8 engine, featuring direct-injection, as well as the latest version of BMW’s ‘Valvetronic’ variable valve timing and ‘Double-VANOS’ variable camshaft control, to produce 460kW (625hp) at 6000rpm, and 750Nm from 1800-5800rpm.

Designated ‘S63’, the engine’s two twin-scroll turbos are located, along with a cross-bank exhaust manifold, in the engine’s (90-degree) ‘hot vee.’ 

The idea is consistent transmission of exhaust energy to the turbos for improved response, with the reversal of usual practice completed by inlet manifolds positioned on the engine’s outer edges.

Drive goes to all four wheels via an eight-speed ‘M Steptronic’ (torque converter) auto transmission with ‘Drivelogic’, and dedicated oil cooling, as well as BMW’s ‘xDrive’ all-wheel drive system.

The xDrive set-up is built around a central transfer case housing an electronically-controlled, variable multi-plate clutch, with front to rear drive distribution set to a default 40:60 split.

The system monitors multiple inputs including, wheel speed (and slip), acceleration and steering angle, and is able to vary the ratio up to 100 per cent rear thanks to the ‘Active M Differential.’ 

Given the angry sounds emanating from under the bonnet of this LS every time I put my foot on the accelerator, I was surprised to find overall fuel consumption for the week was surprisingly good.

I used the LS to drive mostly around town, and yet it beat its own urban claim of 14.2L/100km, settling at 12.9L.100km, closer to the combined fuel figure of 10L/100km.

The hybrid is said to nearly halve this consumption, and I’m inclined to believe it based on previous experience with Toyota/Lexus hybrid systems. 

The LS500 requires at least 95RON unleaded fuel and has an 82-litre fuel tank. That means you're looking at a range of around 635km, using our real-world figure.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.4L/100km, the M8 Competition emitting 239g/km of CO2 in the process.

Despite the standard auto stop/start function, over a week-long combination of city, suburban, and freeway running we recorded a (dash-indicated) average of 15.6L/100km.

Pretty thirsty, but not outrageous when you consider this car’s performance potential, and the fact that (purely for research purposes) we exploited it regularly.

Recommended fuel is 98 RON premium unleaded, and you’ll need 68 litres of it to fill the tank. That equates to a range of 654km in line with the factory claim, and 436km using our real-world number as a guide.

For a seemingly very sophisticated car, there’s something decidedly unsophisticated about the way the LS500 feels from behind the wheel.

Immediately, it feels nowhere near as cutting edge or even as special as something like the LC500, which to me becomes the truest expression of everything Lexus.

No, the LS500 in this turbo V6 guise feels a little bit too old-fashioned. It’s quiet and under acceleration feels like a V8 of just a few years ago, but the Aisin-sourced traditional torque converter automatic transmission is, dare I say, ordinary, lacking the finesse of its German rivals. It’s a problem which is easily solved. Pick the hybrid.

Elsewhere the experience is decidedly Lexus. If you’ve driven even an IS the experience is very familiar in the LS. The touchpoints all match, the steering is light and smooth with a healthy serve of electrical assistance, and, for the most part, the ride is as floaty and comfortable as you’d expect.

I say ‘for the most part’ because there are limits to what the LS’s adjustable-height air suspension will filter out on the enormous 20-inch wheels, complete with run-flat tyres.

Small bumps and potholes are dispatched with ease. Anything too large which passes a certain thud-factor will definitely be communicated to the cabin, though, making for a strange all-or-nothing ride quality.

It is impeccably silent inside, though. The engine is distant, even under load, and tyre noise is virtually non-existent thanks to specially designed alloy wheels with hollow chambers designed to minimise this effect. Now that’s more like what I expect from a Lexus.

It handles very well for such a big unit, making it at least decent to drive for the few buyers who will actually take the helm themselves.

This is no land yacht, it’s a surprisingly agile and adept machine when faced with a bit of blacktop. And it's here where the turbocharged V6 comes into its own compared to the hybrid, offering superior driver engagement.

There’s something teutonically symmetrical about the way the M8 Competition Gran Coupe delivers its prodigious thrust.

Peak torque of no less than 750Nm is available from just 1800rpm, remaining on full song across a broad plateau all the way to 5800rpm. Just 200revs later (6000rpm) peak power of 460kW (625hp!) takes over to finish the job, with the rev ceiling sitting just over 7000rpm.

That’s enough to slingshot this 1885kg bruiser from 0-100km/h in 3.2 seconds, which is supercar fast. And the engine and exhaust noise produced by the 4.4-litre twin-turbo V8 during such rapid acceleration is suitably brutal, courtesy of electronically-controlled flaps in the system opening up. 

On a more civilised drive you can reduce the exhaust noise via an ‘M Sound Control’ button on the centre console.

The eight-speed auto is fast and positive, especially in manual mode, which dials up the fun via wheel-mounted paddles. And when it’s time to direct this car’s forward momentum into lateral movement BMW has brought in the engineering heavy artillery.

Despite its frameless door body structure the M8 Competition Gran Coupe feels solid as a rock thanks in no small part to its ‘Carbon Core’ construction, using four primary components - carbon-fibre-reinforced plastic (CFRP), aluminum, high-strength steel, and magnesium.

Then the ‘Adaptive M Suspension Professional’ (with active anti-roll stabilisation), the tricky xDrive continuously variable AWD system, and active M Sport diff combine to keep everything under control.

Suspension is a double wishbone front, five-link rear arrangement, with all key components in alloy to minimise unsprung weight. In concert with the electronic wizardry on-board, it helps keep the M8 buttoned down with only modest body roll in enthusiastic cornering, as the rear-biased AWD system seamlessly distributes drive to the axle and wheels that can make best use of it.

The price you’ll pay for the track-ready tune is in compromised ride comfort. Even in the ‘Comfort’ setting, the M8 Competition is firm, and feels corrugations and imperfections to a surprising degree.

An alignment of the BMW 8 Series planets left me with the keys to this car and the M850i Gran Coupe (also using the Carbon Core body) at the same time, and the difference between their softest settings is appreciable.

Also be aware that at 12.2m the M8 Gran Coupe’s turning circle is substantial, and it’s just as well all that camera, sensor and self-parking tech is available to help you guide this ship into port.

The M8’s electrically-assisted, variable-ratio steering features an ‘M’ specific calibration to deliver satisfying precision and good road feel. But in similar fashion to the ride a noticeable amount of unwelcome feedback comes through to the wheel.

The fat Pirelli P Zero rubber (275/35 fr / 285/35 rr) grips hard, and the monster brakes (ventilated all around, with 395mm rotors and six-piston calipers up front) wash off speed without fuss or fade.

But overall, you’ll have to live with a less refined drive when you sign on for the M8 Competition. Straight away it feels faster but lacks the M850i’s lighter touch. No matter which drive or suspension mode you select, responses are more aggressive and physical.

To fully explore and enjoy the M8 Competition’s abilities it feels like the race circuit is its most appropriate habitat. On the open road, the M850i is all the Gran Coupe you’re going to need.

The BMW M8 Competition Gran Coupe hasn’t been assessed by ANCAP or Euro NCAP, but that doesn’t mean it’s lacking in terms of active and passive safety tech.

As well as expected crash avoidance features like stability and traction controls, this M8 features the ‘Driving Assistant Professional’ suite which incorporates active cruise control (with ‘Stop & Go’ function) and ‘Night Vision’ (with pedestrian recognition).

Also included are AEB (with pedestrian and cyclist detection), ‘Steering and Lane Control Assistant’, ‘Lane Keeping Assistant’ (with active side collision protection”, an ‘Evasion Assistant’, a ‘Crossroads warning’, ‘Wrong-way warning’, as well as front and rear cross traffic alert.

The headlights are ‘Laserlight’ units incorporating ‘BMW Selective Beam’ (with active high-beam control), there’s a tyre pressure indicator, and ‘Dynamic Brake Lights’ to warn those behind of an extreme braking event.

Plus, M8 Competition owners score complimentary enrollment in the BMW Driving Experience Advance 1 and 2 courses.

To help guide your parking efforts there’s a hi-def reversing camera (with panoramic view monitor), rear parking distance control, and ‘Reverse Assist’. But if all else fails the car can park itself anyway (parallel and perpendicular).

If all of that isn’t enough to avoid an impact, you’re protected by 10 airbags (dual front and front side, knee bags for the driver and front seat passenger, as well as side airbags for the second row, and curtain airbags covering both rows).

An automatic emergency call function contacts the BMW call centre for connection to relevant services in the event of a crash. And as has been the case with BMW since the dawn of time, a first-aid kit and warning triangle are on-board. 

Lexus offers a five-year and unlimited kilometre warranty, and LX buyers get three years of complimentary membership to the brand’s ‘Encore Platinum’ owner experience, which includes three years of capped price servicing, free loan cars at the time of service, invites to events, discounts on fuel at Ampol outlets, and four uses of ‘Lexus On Demand’ which lets owners swap into another Lexus model for up to eight days at a time, as well as eight free uses of valet parking at certain locations.

Servicing on the LS occurs once every 12 months or 15,000km and is fixed for the first three years at $595. Very cheap for the space it plays in.

BMW offers a three year/unlimited km warranty, which is at least a couple of years off the mainstream market pace, and lagging other premium players like Mercedes-Benz and Genesis, both sitting at five years/unlimited km.

Roadside assistance is included for the duration of the warranty period, and the standard ‘Concierge Service’ provides everything from flight information, to global weather updates, and restaurant recommendations, from a real human.

Technically, service is ‘condition based’ with the car telling you when it’s time to hit the workshop, but you can use every 12 months/15,000km as a guide.

BMW Australia offers ‘Service Inclusive’ packages that require customers to pre-pay for servicing, allowing the cost to be covered off in finance or leasing packages and reducing the need for concern about paying for maintenance further down the track.

BMW says there are different packages available, from three to 10 years, or between 40,000 and 200,000km.
