BMW M5 vs Lexus LC500H

What's the difference?

Let’s get one thing out of the way: the new M5 is a very good car. Considering the emissions limitations and size increase of its base model, it is an impressive bit of engineering. 

What’s trickier is deciding whether the new car is really better to drive. Less edgy but supremely comfortable and quiet; BMW leaned into the daily usability of the plug-in hybrid M5 rather than amping the petrol-electric system for maximum thrills. And do you know what? That’s fine with me. 

The new M5 still performs on road and track and does an incredible job of hiding its weight (most of the time). Perhaps the G90 is a little more Audi RS6 than F90 in its demeanour but some would argue that’s no bad thing. 

The concept of the BMW M5 is not static, it evolves with the times, and the G90 is no exception. Expect future Competition and CS variants to unlock some extra lunacy. 

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

A truly fuel-efficient performance car, who’d have thought? There are some obvious trade-offs for trying to exist in two seperate worlds, but the Lexus LC 500h largely handles its dual roles with aplomb.

The M5’s raw size is what you notice first. The G90 M5 is a whopping 113mm longer, 67mm wider and 37mm taller than the car it replaces, with the wheelbase stretched 24mm.

It is also the most pumped M5 yet, compared to a 520i it is 70mm chubbier at its flared wheel arches. The ‘M5’ insignia on the C-pillar means you’ll know this is the fast one. 

Presence is not in question, then, but beauty? Not the right word. The G90 makes its predecessors — especially the original ‘E28’ — look demure. 

The cabin layout builds on the concept debuted by the iX electric SUV, with twin integrated screens and focus on technology and minimal buttons. Materials are mostly high quality and feel fitting for the M5’s asking price.

It's a little curious, the LC 500h. For mine, it's stunning from a distance. All gleaming alloys and bulging rear arches and sharp snout angled downward like its caught the scent of its prey.

But weirdly, it can start to look a little less impressive the closer you get to it - a little swollen and vague in its lines. It's very likely it's eye-of-the-beholder stuff (fellow CarsGuide scribe Richard Berry adores it from every angle, for example).

Inside, the front of the cabin is a busy but stylish space, with multiple textures layered on top of each other to produce a premium-feeling, sporty space. The low-feeling dash juts out, giving the front passengers an ensconced, cockpit feel.

Everything is predictably leather-wrapped and lovely, and while it's not as streamlined as, say, an Audi interior, it's not without a genuine sense of Japanese charm in the cabin.

BMW has persevered with its twin-screen, minimal-button approach for its 'Operating System 8.5' in the M5. 

The 14.9-inch central touchscreen is bright, responsive and high resolution but the software remains a little strange. The main interface is classy but when looking for settings to adjust you’re presented with a Windows 95-esque panel of small square touch targets. It’s not intuitive. 

Wirelessly mirroring Apple CarPlay or Android Auto works a treat, at least. Digital climate controls keep temp adjustment persistently on screen and a shortcut to fan speed. The nipple-like vent direction adjustment grows on you, as do the digital vent sliders. 

The 12.3-inch digital driver’s display still doesn’t have the freedom of customisation and clarity of Audi’s interface. 

The M5 has two cupholders, a deep central storage cubby, door bins that swallow two 600mL plastic bottles and twin wireless charging pad that resolutely grips smartphones even under the sort of tummy-churning G-Forces this M5 can manage. 

Setting the M5 apart from the regular sedan is a unique centre console bunching 'M Drive' modes, 'M Hybrid' modes and other shortcut functions together next to the gear toggle and M-engraved crystal 'iDrive' controller.

Comfortable front seats are power adjustable with in/out, up/down lumbar support and have two memory positions. 

The 5096mm long M5’s back seat is very spacious. Headroom is good for those beyond 182cm (six-foot), the bench is extremely supportive, while leg and toe room are adequate.

A fold-down centre armrest has two cupholders and there are USB-C charge ports in the back of each bucket seat for a total of four. 

You can buy an accessory mount that holds tablets or smartphones for rear seat passenger entertainment, too.

When you look in the boot, BMW offering a Touring version of the latest M5 makes even more sense. The load aperture is big but the usable space is narrow; the sides intrude on load space. 

The 466-litre space will make fitting suitcases for an airport run tricky and, even with the 40/60 split-fold rear bench, you will struggle to fit a bike in the back. There’s no spare tyre, either.

It's not really. Especially in the backseats, which would make more sense if they were painted on. I'm no giant, but even my 175cm-tall head was pushed into the ceiling, and while there’s ample shoulder space for two adults, you’re unlikely to be able to convince two to get back there. 

Lexus has included something called the "Easy Access" function for 2020, which sees the front seats slide forward automatically to help with accessing the rear seats, and they do lower the Cirque du Soleil antics required to get back there, but this realistically not a car for carrying more than two adults, save an emergency. There are two ISOFIX attachment points in the rear, so child seats can be locked in there. 

That's not necessarily a drawback, though. This is a two-door sporty coupe, after all, and elsewhere, the sizeable dimensions (4770mm length x 1920mm width x 1345mm height) provide plenty of space for up-front riders.

You'll also find hidden cupholders, bottle holders in the doors, and all the power and connection points you need. 

A word on the tech, though. The LC 500h is crying out for a touch screen, though the brand's traditional mousepad system is improving.

Value is all about perspective, of course, and viewed the right way, the $195k sticker price of the Lexus LC 500h does provide a certain amount of value.

Yes, it's a lot of money. But Lexus' flagship coupe doesn't just get a performance-focused hybrid setup (pairing with a thumping V6 engine), but also just about every high-end feature the brand has in its deep bag of tricks.

It starts outside with giant 21-inch alloys, a glass roof with a sun blind,  LED headlights with cornering lights, hidden door handles, keyless entry, and rain-sensing wipers.

Inside, you'll find leather-accented seats, a colour head-up display, a 10.3-inch multimedia screen with Apple CarPlay and Android Auto, another 8.0-inch screen in the driver's binnacle, a heated steering wheel, heated and cooled front seats, DAB+, satellite navigation system with live traffic, and a killer 13-speaker, 918-watt Mark Levinson stereo.

Unlike the Mercedes-AMG C63, BMW has kept the M5’s eight-cylinder heart and this has proven to be a good decision. 

The 4.4-litre twin-turbo petrol engine has been optimised with “a cross-bank exhaust manifold and optimised oil separation”, says BMW.

The V8 spins to 7200rpm though it isn't a screamer, outputting a full-bodied 430kW (5600-6500rpm) and 750Nm (1800-5400rpm).

Augmented with a transmission-mounted 145kW electric motor that can produce up to 450Nm, thanks to pre-gearing, maximum combined outputs are 535kW and 1000Nm. 

Weight blunts punch, though, so despite nearly 100kW and 250Nm more, the new M5 is a tenth slower to 100km/h than its predecessor (claimed), at 3.5 seconds for the sprint.

You can thank a 220kW/tonne power-to-weight ratio, worse than the old car's 233kW/tonne figure. The new G90 claws some time back with brute force, hitting 200km/h in just 10.9 seconds and goes on to a limited top speed of 305km/h.

You can choose from five powertrain settings, starting with 'Electric' and 'Hybrid' for everyday use, while 'eControl' lets you store battery power for urban use.

'Dynamic' provides the best balance, says BMW, while 'Dynamic Plus' is like a qualifying mode. Think maximum combined punch for up to 10 minutes, at which point you’ll have drained the battery. 

Driving in pure electric mode, the take-off can be a little jerky but the quietude and decent power make it pleasant. Power sources are combined expertly in Hybrid and giving it some stick in Dynamic is more than enough to make your passengers feel queasy.

The LC 500h is powered by a hybrid setup that combines a 3.5-litre V6 engine with a 650-volt "Lexus Hybrid Drive" system and a lithium-ion battery. That setup delivers 264kW of power, and somewhere north of 350Nm in torque when the engine and motor outputs combine.

That power is sent to the rear wheels via a CVT automatic, and will produce a sprint to 100km/h of around 5.0 seconds. 

According to Lexus, 10 clear improvements were made the way the 2020 LC 500h drives, including a new transmission tune, more structural bracing added for rigidity, new suspension components and spring rates, and altered stabiliser bars. 

Has it made a difference? Read on. 

Electric-only range is rated up to 69km in WLTP testing, but the 18.6kWh battery is more likely to give you around 60km in real-world driving. It can be topped up in about two hours using an 11kW AC charger, or overnight on a three-pin socket. 

BMW includes both Mode 3 (public) and Mode 2 (home) charging cables with the M5. 

The M5 uses 3.2L/100km of 98 RON premium unleaded in ADR testing, corresponding to just 72g/km of CO2, so it should sail through the first rounds of Australian emissions regulations. 

Indulging in what the V8 has to offer sees that consumption spike, though. An enthusiastic road drive saw the M5 gulp 12.4L/100km, according to the trip computer.

Lexus says the LC 500h will sip 6.8 litres per hundred kilometres on the combined cycle - very impressive for what is ostensibly a performance coupe - and emit 152g/km. 

The LC 500h is equipped with an 82-litre fuel tank. 

The three M5 elements start with daily usability. We trundled out of Bathurst in electric mode, with the adaptive dampers (and other myriad settings) in Comfort. 

The M5 has steel springs, double wishbone front suspension and a five-link rear axle, all of which has been heavily reworked by the boffins at M. Naturally, the ride is firm, though in Comfort the body moves through its motions smoothly. 

The M5 is an effortless tourer, its eight-speed automatic shmoozing through ratios as it climbs and descends steep gradients. Wind and tyre noise insulation is good on coarse chip tarmac, though a bit more burble from the V8 would be appreciated. 

The M5 has nine adjustable parameters to wake it up: 'Drivetrain', 'Energy Recovery', 'Drivelogic' (gear shift aggression), 'Chassis', 'Steering', 'Brake', 'M xDrive', stability control settings and 'M Sound'. Favourite settings can be stored to the wheel-mounted M1 and M2 buttons. 

With the dampers still in Comfort the M5 remains fantastically capable with power delivery from the xDrive mighty rewarding on corner exit. Sport dampers sharpen the experience up further, amplifying the M5’s surprising agility. Thank the rear-wheel steer for this big sedan’s switchback performance. 

Step beyond the limit of grip, brake too late, or get on the power too early, though, and the M5’s mass reveals itself rapidly. It doesn’t help that the accurate steering is devoid of feel. The brake-by-wire pedal is too numb and light, as well, making it tricky to judge grip levels on the road.

Feel is less of an issue on a dry Mount Panorama circuit, where the M5 turns out to be a total pussycat. The all-wheel drive, consistent dynamics, strong brakes and well-tuned stability control make for an approachable but seriously fast sedan.

The responsive transmission will hold gears to redline and is eager on the downshift in its most aggressive setting while tactile shift paddles make commanding ratio changes yourself that bit more engaging. 

Prodigious punch out of corners is matched by the impressive consistency of the carbon ceramic brakes. The M5 pulled up for The Chase every time with minimal fuss, even from above 250km/h.

Similar credit goes to the 285mm front and 295mm rear Hankook S1 Evo tyres which remained consistent and predictable all day despite reaching temperatures over 130 degrees, according to the tyre pressure monitor.

There’s something very strange about hitting the start button in what is ostensibly a sports car, and being greeted not by the bark of an exhaust, but by the gentle whirring on the car’s electronics coming to life.

But then, the Lexus LC500h is not your average performance car.

It essentially trades the out-and-out grunt of its V8-powered sibling (which produces a monstrous 351kW and 540Nm) for a kind of best-of-both-worlds approach that pairs the punch of the V6 engine with the fuel efficiency of a hybrid powertrain. 

If that sounds like an compromised approach to pure performance, you're right. But reframe the way you look at the LC 500h and it all starts to make a bit more sense.

Remember, this isn't a track-attack weapon, but a potent on-road bruiser, and the flow of power on offer always feels ample, and you never want for too much more off-the-line pace on public roads. 

Among the biggest selling points of the LC 500h is the sheer distance between its various personalities. Engage Eco, or even Normal, drive modes, and it’s a quiet, mostly very comfortable (though it can be unsettled by bigger bumps) kilometre-eater, but engage Sport or Sport Plus and it rightly transforms into something significantly angrier.

It might not be the absolute sharpest tool in the performance car shed, but the LC 500h does bristle nicely when those modes are engaged, the hybrid factor seemingly replaced by a satisfyingly meaty exhaust note and an accelerator that’s suddenly far more sensitive to the touch.

The steering feel is nice and the inputs direct, but there is something about the car’s 1980kg weight that doesn’t inspire the deepest of confidence, at least not on the rain-slicked roads we were travelling along .

A pure performance coupe? Perhaps not. But a sporty, stylish and, when you want it to be, comfortable cruiser with the ability to turn the volume up when you come across a twisting road? Bingo.

The Lexus LC 500h is yet to be ANCAP tested (the price would likely prove a sticking point), but the Japanese brand has fine form in attracting top marks, and there's certainly no shortage of safety features on offer here. 

There's a total eight airbags and a reversing camera and parking sensors, as well as a host of high-tech kit like AEB, Lane Keep Assist, Blind Spot Monitoring, active cruiser control and a bonnet that will sense pedestrian and pop up before impact in an attempt to minimise injury. 

In Australia, BMW has moved to match other manufacturers in offering a five-year/unlimited kilometre warranty on all its cars. 

Servicing is recommended on a condition basis, with the M5’s multimedia system prompting a visit to the mechanics. BMW offers pre-paid service packs for five years/80,000km at a price of $5059 for the basic offer and $8152 for 'Inclusive Plus', which covers brake pad and rotor replacements. 

It is expensive next to a regular 5 Series but when you consider the purchase price and performance level, the M5’s service pricing is not astronomical. 

So, to ownership. Let's start with the basics first, before we move onto the new Encore Platinum benefits. 

The LC 500h is covered by a four-year/100,000km warranty, and servicing (capped for three years at $595 a pop) is required every 15,000km.

You will know already the Lexus's stellar Encore ownership program includes handy features like valet (pick-up and drop-off) servicing, but the new Encore Platinum level for owners of its more exclusive models unlocks some seriously cool stuff. 

One is a new On Demand service, which allows owners to book a different style of car when heading off on a holiday or business trip. So, say you own the LC 500h, but want to take the family to the snow and need a seven-seat 4WD like the RX L, then Lexus will lend you one at no charge, which you can keep for eight days.

The loans are available in your state or somewhere else in Australia if you're travelling, with your car waiting for you at Qantas Valet for you when you arrive. 

The One Demand service is available on four occasions over your first three years of ownership (which is also the length of the Encore Platinum membership). 

The Platinum level also provides eight examples of free valet parking at select shopping centres, as well as hotel and restaurant benefits, and invitations to Lexus' drive days around the country.
