BMW M5 vs Toyota Supra

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.

The Toyota GR Supra GT is a superb sports car that’s relatively easy to live with in the city even with the manual gearbox and incredibly fun to drive out where the roads are free from traffic.

Not only is the GT great for the price compared to rivals but it’s the pick of the Supra range.   

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.

Perhaps it’s just me but I think the Supra looks exactly how it should look - like a Hot Wheels car.

Seriously, how good does the back view look? I love the spoiler that angles up like a crazy ski jump and the tail-lights integrated underneath it.

I love the huge rear hunches swollen like they’ve been stung by an enormous wasp. Check out the roof - see how it’s curved? And that bonnet with the vent above the wheel arches, I love the styling of every millimetre of this car.

But my neighbour doesn’t. I pulled up and said, “How good does this look?” And he gave me this stare like I was bonkers.

I don’t know, maybe you and I have the same excellent taste, but if there’s anything I hate it's anything that’s boring.

To me the BMW Z4 ‘twin’ is getting very close to the boring end in the styling department. 

Talking of BMW, the Supra's interior is very BMW from the indicators stalks to the media system and climate control set-up.

It’s a modern and minimalist cabin… if only there wasn’t a cupholder right where my elbow goes. That’s a good place to stop and talk about the Supra GT’s practicality. 

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.

The good news is that if you’re tall like me (189cm) and mainly legs then you’ll have more than enough legroom and headroom because the footwells are impossibly deep and the seats can be lowered to what feels like ground level.

Actually, you are almost at ground height in this car so the bad news if you’re as tall as me you’ll probably have to crawl out of the car on all fours.

The cabin of the Supra doesn’t do the storage space thing well. Sure there are two cupholders but their location is the same place my elbow frequents while changing gears and resting.

The wireless phone charging area is good and easy to access, but the door pockets are as thin as post box slots so if it’s letters you’re storing there you’re in luck.

If it’s anything thicker than that you’ll be left looking around for a place to put your purse or wallet and end up throwing it in the phone charger space if the passenger seat is taken.

You could always ask your co-pilot to hold onto your things which reminds me to tell you that the Supra is a two-seater only. There are no back seats, and there’s no option to have back seats.

If you’re looking for a sports car with rear seats (although space will be limited) for the same money then there’s the Audi A4 45 TFSI and at an even lower price is the Ford Mustang GT.

If you look over your left shoulder while in the driver’s seat of the Supra GT you’ll see into the boot -  there’s no wall separating the cabin from the cargo area. This is handy for throwing a school bag in as I did for my son on the morning drop off, but also means your items may make an unexpected visit to the cockpit if you stop suddenly.

The boot is large for a sports car at 296 litres (VDA) and it managed to fit our large CarsGuide suitcase with space to spare as you can see in the images.

The Toyota GR Supra GT with the manual gearbox lists for $87,380 and you’ll pay the same price for the same car with the automatic transmission. 

Yes, almost $90K might sound like a lot of money for a Toyota (unless it’s a LandCruiser) but it’s actually a bargain considering the GTS grade above costs $10K more and has the same engine plus pretty much the same features apart from a fancier stereo, head-up display and 19-inch alloys (rather than the 18s on this GT).

Also, if you didn’t know already the Supra is a BMW/Toyota joint venture model aligned with the BMW Z4, and if you want the Beemer version with the same engine as the Supra GT you’ll pay $139,800 for it.

So see, it’s a bargain in comparison.

The standard features list of the GT has pretty much everything you need. There’s a proximity key, LED headlights with adaptive high beam, active cruise control, sat nav, wireless Apple CarPlay and Android Auto, a 10-speaker stereo, wireless phone charger, heated and power adjustable seats, shifting paddles and sports pedals. 

Great features, but let down only by a small 8.8-inch screen for your media and nav. Still, that absolutely shouldn’t be a deal-breaker for you.

The rivals? Well, clearly the BMW Z4 which is way more expensive, but also there is the Nissan Z which costs between $70-$80K and is also a hoot to drive.

Add the Ford Mustang GT to your research list, as well. It’s not as agile as the Supra but it’s quick, fun and sounds better to my ears. 

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.

You’re looking at a Supra that could be the peak of its model evolution because since the generation’s arrival in 2019 Toyota has increased the power of the 3.0-litre turbo-petrol in-line six-cylinder from 250kW to 285kW (torque remains the same at 500Nm) and introduced a six-speed manual. 

This 3.0-litre six-cylinder turbo-petrol is the only engine you can have with the Supra, there are no four cylinders or V8s - now there’s an idea. 

Toyota says the 0-100km/h time for the GR Supra with the manual gearbox is 4.4 seconds and 4.1 seconds for the automatic which comes with a ‘launch control’ feature.

Of course, all Supras are rear-wheel drive.

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.

Toyota says the 3.0-litre six-cylinder straight-six turbo-petrol engine in the Supra GT paired with the six speed manual gearbox should use 8.9L/100km after a combination of open and urban roads.

I did a week’s worth of city commuting and then a couple of hundred kilometres on country roads, but no motorways and the trip computer told me I was averaging 10.3L/100km.

Not bad for a big engine in a car tuned for performance, driven by a big kid who feels like he’s playing with somebody else’s toys.  

Premium 95 RON fuel is recommended, although 'standard' 91 is acceptable. A 52-litre fuel tank translates to a theoretical range of around 580km, dropping to approximately 500km using our real-world number.

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.

Ah, but what about living daily with a manual? As a car enthusiast most of the cars I’ve owned have been manuals and I’ve rarely cursed them because I love to drive.

But there were times when they were a pain, such as in traffic, or in traffic on steep streets and in traffic in shopping centres. Did I mention in traffic, also?

But on the nice roads with bends and dips, hills and sweeping corners, hairpins and twisty parts in places without traffic, then all is forgiven. 

And so it goes with the manual version of the Supra. 

Making life easier in the Supra GT is a clutch pedal without much travel so you don’t feel as though you’re at the gym doing a one-sided leg press.

I found the shifts themselves, while short, to be less than smooth. At first, I thought that the clunky changes might have been because the gearbox hadn’t been run in yet, but the odometer was saying 7500km, so this could just be the nature of the gearbox and after a few days I became used to it.

The rev-matching feature of this gearbox is a nice touch, especially on those sporty drives when you change into a gear and you’re thrown straight back into the power band again.

Superb balance, great steering with a nose which points exactly where you want it to and that magnificently smooth turbo-petrol in-line six posting all its meaty grunt to the rear wheels just behind your shoulders makes for a sports car that’s fun, talented and quick.

Good brakes (348mm ventilated rotors with four piston calipers at the front and 330mm discs with single piston calipers at the rear) and grippy Michelin Pilot Supersport tyres (255/40 fr - 275/40 rr) complete a great package. 

A ride that’s still comfortable over bad Sydney roads and surprisingly good visibility made the Supra easy to live with in the city, from parking to school drop offs.

Yes, used it each day for the school run with my older child and the grocery shopping. 

The GR Supra GT has not been crash tested by ANCAP, but its BMW Z4 twin scored a maximum five stars when it was tested by the European equivalent Euro NCAP.

Still, the Supra has seven airbags, there’s AEB with pedestrian and cyclist detection, lane keeping assistance and blind spot warning, plus front and rear parking sensors. There are seven airbags on board.

There’s no spare wheel, but there is a tyre inflation kit which should get you out of trouble.

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. 

Toyota covers the GR Supra GT with its five-year, unlimited kilometre warranty. Servicing is required every 12 months or 15,000km and is capped at $415 per service.

The warranty is the industry standard in terms of time and kilometre length, and the capped service prices are very reasonable - a lot more affordable than a car with a prestige badge on the bonnet, too.
