Toyota GR Yaris vs BMW M5

What's the difference?

The GR Yaris GTS with the Aero Performance Package is a so wonderfully special with its brilliant engineering, mind-blowing dynamics and fun-to-drive nature. The new aero package makes an already angry beastie look furious, making it the perfect enhancement that's also functional.

The only lower marks here are for warranty, fuel use and practicality. But if there was a score for fun it'd be a 10/10.

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.

The GR Yaris exists so that Toyota could go racing in the World Rally Championship. As with many racing series it required Toyota to build a road-going version of their Yaris race car, also known as a homologation vehicle. It’s a good deal, they get to race, you get a race car for the road. And so the GR Yaris was born. 

Wildly different from a regular five-door garden variety Yaris, the GR Yaris is a hand-built three-door hatch with a wider track, wider and lower body and the use of forged carbon and aluminium for lightweight construction.   

The GR Yaris already looks very angry, but the GTS Aero Performance Pack makes it look furious. It adds a huge adjustable rear wing, fender ducts that channel air, a front spoiler lip that aids stability, a giant bonnet scoop to help release air, and rear bumper ducts to reduce drag. 

The GR Yaris’s cabin was redesigned for the 2025 update and that saw the dashboard angled more to the driver much like in a race car, but it's more functional than fancy and it’s all very plain.

Still, we’re not complaining. The seats are lovely and the red stitching is a nice touch but this isn’t a Lexus. It’s supposed to favour function over form and so the design is absolutely fitting. And by function I mean dynamics and not practicality.

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.

The regular Yaris is small, the GR Yaris is smaller at 3995mm end-to-end and with two fewer doors. As a tall person (I’m 1890mm end-to-end) the space on board is adequate up front with just enough knee, head and elbow room.

The GR Yaris is a four seater with the two rear seats accessed through the front doors. There’s not much room in there for adults and not even my lanky 11-year old would be happy in there. Still if you need to carry three other people, technically you can.

Cabin storage is limited to fairly large door pockets and two cupholders between the front seats. There is a little shelf carved into the dashboard which is great and a small glovebox below it.

Boot space is tiny at 174 litres but again this is a small car with other priorities. 

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 last M5 was well equipped but the new car is wanting for nothing. Australian cars have just about every option for $259,900, before on-road costs.

Australian M5s wear staggered 20-inch front and 21-inch rear alloy wheels paired with standard metallic paint, 'M Carbon Exterior' package (including carbon roof and rear lip spoiler), adaptive LED headlights and BMW’s 'Iconic Glow' illuminated kidney grille surrounds. 

Keyless entry, a heated steering wheel, heated and ventilated front seats, interior camera, powerful 18-speaker Bowers & Wilkins sound system, M seatbelts, four-zone climate control and a power tailgate are the cabin highlights. 

Optional extras are thin on the ground; you can choose from (eight) no-cost paint colours and all manner of 'Individual' shades (from $4100), four interior trims including classy 'Dark Oak' wood and four leather colours. There’s classic black ‘Merino’ leather, or you can have it dyed with a mix of 'Silverstone', red or 'Kyalami Orange'. 

Aside from that, the only major option is carbon ceramic brakes at a staggering $18,500, and an M5 Touring wagon costs $263,900. 

Though the M5 is more expensive than Audi’s closest rival, the RS6, the gulf isn’t huge considering you get a lot more punch in the BMW. Mercedes-AMG does not have an E-Class answer, yet.

Good value, then? Well, an equally potent Porsche Panamera is twice the price. So yes, in a sense.

It still boggles my mind how 221kW and 400Nm is extracted from a 1.6-litre three-cylinder petrol engine but here we are. The GR Yaris has this set up with this output, along with all-wheel drive. 

Thanks to lightweight materials such as forged carbon and aluminium the GR Yaris weighs nothing in car terms - just 1300kg - so acceleration from 0-100km/h is a rapid 5.1 seconds.

I’ve already detailed the juicy engineering bits the GTS Aero Package is fitted with, from the limited slip diff to the adjustable rear wing, and it’s not an exaggeration to say that not many small hatches are this gifted with this kind of genius.

Our test car has an eight-speed automatic, which is easy to drive in city traffic. However, I'd opt for the six-speed manual because if you've come this far you may as well go the whole way.

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 GR Yaris is a hungry beastie that eats through its 50L petrol tank fairly quickly and then wants more. Toyota says you should see 9.1L/100km of 98 RON used in the automatic and 8.2L/100km with the manual over a combination of driving conditions. 

Stop-start city driving in traffic saw fuel use increase dramatically to 13.0L/100km in the auto. According to our car's trip computer, my own testing used an average of 14.5L/100km after mainly suburban driving.  

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.

There’s been a multitude of electric cars through the test garage over the past six months and the GR Yaris is like a diamond found in a tub of Lego when it comes to driving.

So much sound. The three cylinder snarls on start up sending vibrations into the cockpit and up through the steering wheel, the transmission can be heard engaging gears, the big brakes creak as they’re released. And we’re hardly even moving yet. There’s so much theatre. It’s all real and I love it!

I even love that in the first 10 minutes of driving, a message appears on the instrument cluster asking that excessive acceleration be avoided while the engine is cool. You don’t get that beautiful inconvenience in an electric car.

But when you can excessively accelerate (on a race track of course, right?) it's wonderful and it's loud. Lift off, and the wastegate lets out a little "weeee!" in excitement.

I don't need to tell you that the GR Yaris handles better than just about anything in this price range and while the ride is firm and speed bumps feel like you’ve hit a gutter I still drove the GR Yaris every day, even to do the school run, because it is so much fun. Meanwhile my hybrid long0term test car looked lonely in the driveaway all week...

Being an automatic makes it easy to drive in traffic and the small size makes finding parking spots quick and simple.

Visibility is good, steering is excellent, the seats are big enough to accommodate me but snug enough to offer good lateral support, too.   

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.

The regular BMW 5 Series range scored a maximum five stars in 2023 ANCAP safety testing but this does not apply to the M5.

The M5 features nine airbags and a host of active safety systems, including auto emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, auto parking and speed limit assist. 

Lane-keep can easily be turned off via two taps but the other systems require more menu navigation, though are mostly unintrusive. A 'Track' mode disables lane-keep, AEB and other systems along with switching the central display off. 

The GR Yaris is covered by Toyota's five-year/unlimited-kilometre warranty which is lacking compared to many other mainstream manufacturers’ seven-year-plus warranties. The good news is that the engine and driveline is covered by an extra two-year warranty.

Servicing is capped at about $300 for the first six visits, although services are six months apart which means that after three years you’ll run out of capped-price servicing.

Still, Toyota’s reputation for reliability does provide some peace of mind. 

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.
