BMW M135i vs Toyota GR Yaris

What's the difference?

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

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.

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

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.

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

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. 

The GR Yaris GTS Aero Performance Pack sits at the top of the model range with the six-speed manual version listing for $64,990 before on-road costs, while the automatic is $67,490. That’s $4500 more than the standard GTS without the aero pack

The aero pack significantly toughens up the look of the GR Yaris, and also improves its dynamics. So if you plan to use the GR Yaris as a track car and drive it hard and fast, the kit will help.

That's thanks to improved down force from the giant rear wing, air ducts in the fenders to improve steering under braking, a front splitter for stability, underbody cladding to maximise airflow and a bonnet scoop to help release hot air from the engine bay.

The rest of the high-performance equipment comes on the regular GTS including a Torsen limited slip differential, high performance suspension tune and 18-inch forged wheels with Michelin Pilot Sport 4S tyres.

Standard features are the same as the regular GTS and include heated GR sports front seats with suede leather upholstery, a 12.3-inch digital instrument cluster, leather-wrapped steering wheel, aluminium pedals, dual-zone climate control, proximity unlocking and push-button start.

There's also an eight-speaker, eight-inch media screen with Apple CarPlay and Android Auto, and an eight-speaker JBL sound system.

The value is actually great considering all the high-performance engineering around you in the GR Yaris, and it will save you money from being tempted to go down the aftermarket route and buy equipment that hasn't been designed for the car by the people who made the car.

There are some nice comforts, too, like the leather seats, although the media screen is small.   

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front axle.

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.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

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.  

For a brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

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 GR Yaris has not been crash tested by ANCAP and the score for the regular Yaris can't be applied to the GR version.

Still the GR Yaris comes equipped with an array of advanced safety tech such as auto emergency braking (AEB), lane keeping assistance and a blind spot warning.

There are six airbags, two child seat ISOFIX points and two top tether anchor mounts in the rear row.  

BMW is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product. 

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.
