BMW M135i vs BMW M2

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:

As the ultimate form of the current M2, the CS distils the best aspects of what everyone loves about BMW into one tidy little package.

The driving experience is nothing short of divine, even if the manual gearbox shifts could be better, while the firecracker engine kicks things up to a whole new level.

If only BMW offered more equipment and safety to round out the $140,000 pricetag, or maybe they should have leaned harder into the lightweight aspect and ditched the rear seats to make the M2 CS even more special.

At the end of the day though, the M2 CS is still an unbelievably appealing driver’s car, and I can’t wait to see what BMW has in store for the next one.

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.

We’re already big fans of the way the M2 looks, it’s just the right size and has the perfect proportions for a sporty coupe, and the CS just takes things to another level.

From the outside, the M2 CS scores a noticeably bigger bonnet bulge, as well as a vented hood to improve airflow.

The front splitter, side mirrors, skirts, bootlid spoiler and rear diffuser are also finished in carbon, and add to the car’s aggressive demeanour.

Filling the wheelarches are 19-inch wheels finished in black, but tucked behind those are massive drilled brake rotors and large calipers painted in red.

To call the M2 CS exterior design sporty would be an understatement, but we do have to point out that the Alpine White of our test car did look a little boring, despite the extra bling.

If we were buying one? We’d option the stunning Misano Blue hero colour with gold-coloured wheels to really turn heads around town and at the racetrack, although they will add another $1700 and $1000 respectively to the already dizzying price.

Inside, the M2 CS is let down a little by a spartan interior, which looks like it’s been lifted from the cheapest 2 Series coupe, due to the lack of climate-control screen.

However, BMW does try its best to spice things up with very tight-fitting bucket seats, an Alcantara steering wheel, CS-branded dashboard and that carbon-fibre transmission tunnel.

It’s definitely a case of function over form , but the lack of interior flare means you focus more on the road ahead than anything else, which is no bad thing when you have 331kW and 550Nm being sent to the rear wheels.

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. 

Measuring 4461mm long, 1871mm wide, 1414mm tall and with a 2698mm wheelbase, and just two doors, the M2 CS isn’t exactly the last word in practicality.

Of course, front passengers are afforded plenty of space, and the electronically adjustable bucket seats allow you to get into the right position to row through the gears and eat up the road.

Storage is limited, however, with average-sized door bins, two cupholders, a small wallet/phone tray, and that’s it.

BMW is generous enough to include a single USB port to charge your device, but its location, where the armrest should be, means you’ll have to get creative with cable management to make it really work if you want to keep your phone in the tray under the climate controls.

Predictably, the two rear seats are less than ideal for anyone tall, but there is plenty of leg and shoulder-room.

A small centre-storage tray is fitted back there, as well as Isofix points for the seats, but there isn’t a whole lot to keep rear occupants entertained. They'll probably be too frightened to care.

Opening the boot reveals a small aperture that will swallow 390 litres, and is shaped in such a way that a set of golf clubs or some overnight bags will fit in nicely.

There are some luggage tie-down points and netting to keep your belongings from rolling around, and the rear seats fold down to accommodate longer items.

Pricing for the 2021 BMW M2 CS starts at $139,900 before on-road costs for the six-speed manual, with the seven-speed dual-clutch automatic bumping up to $147,400.

Let’s not mince words here, the BMW M2 CS is not cheap.

Compared to the M2 Competition , the CS adds about $37,000 to the bottom line – the equivalent of a well-specced small SUV – and sits perilously close to the new-generation M3 and M4 ($144,900 and $149,900 respectively).

For the price , buyers are getting exclusivity, with just 86 examples available in Australia out of a total global production run of 2220 units.

The engine is also tuned for a higher power output, but more on that below.

Standard equipment in the M2 CS also eschews luxury for sportiness, with carbon-fibre exterior highlights, a new exhaust, lightweight 19-inch wheels and Alcantara steering wheel.

The front seats are borrowed from the M4 CS, and trimmed in Alcantara and leather, but that’s about all you get for equipment.

The multimedia system shares the same dimensions as the rest of the M2 line-up, measuring 8.8 inches and including satellite navigation, digital radio and Apple CarPlay (no love for Android owners, sorry).

The climate controls do differ slightly, with the slender screen replaced with basic buttons and knobs.

Seat heating? Nope. Rear air vents? Sorry. How about keyless entry? Not here.

Also noticeably absent is a wireless smartphone charger, and centre armrest, as the usual transmission tunnel has been swapped out for a carbon-fibre piece.

To be fair, you do get a premium Harman Kardon sound system, push-button start and single USB port, so at least BMW does offer a way to charge your phone on the go.

Perhaps most egregious of all though – at least to me – were the rubber pedals fitted to our manual test car.

For $140,00 you’d expect a bit more in terms of convenience features, and before you make the argument that ‘it’s all about saving weight’, don’t bother, because the M2 CS and M2 Competition both tip the scales at an identical 1550kg.

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.

Powering the BMW M2 CS is a 3.0-litre twin-turbo ‘S55’ six-cylinder engine, developing 331kW/550Nm.

With drive sent to the rear wheels via a six-speed manual or seven-speed dual-clutch automatic transmission, the M2 CS can accelerate from zero to 100km/h in 4.2 or 4.0 seconds respectively.

Peak power is available at a heady 6250rpm, while maximum torque comes on stream from 2350-5500rpm.

The M2 CS actually put out as much grunt as the outgoing M3/M4 Competition, because it uses the same engine, and to say the amount of performance on tap is explosive would be to talk up explosions. This is a serious amount of bang for your buck.

The M2 CS easily outclasses the likes of the 280kW/460Nm Jaguar F-Type V6, 306kW/410Nm Lotus Evora GT410 and 294kW/420Nm Porsche Cayman GTS 4.0.

I do have to draw attention to the manual gearbox of our test car, though, which was great, but not excellent.

With such engaging shifters fitted to the Honda Civic Type R, Toyota 86 and Mazda MX-5, I expected rowing through the gears would be nirvana, but it was merely OK.

The throws are a little too long for my liking, and it takes just a bit too much effort to slot it into the right ratio. Still, we should all be glad to see a manual offered here, and I'm betting it is still a better option for purists than the auto.

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. 

Official fuel-consumption figures for the M2 CS are pegged at 10.3 litres per 100km, while our week with the car yielded a more realistic figure of 11.8L/100km.

Engine start/stop technology is included to keep fuel consumption down, but our week with the car was spent mainly in Melbourne’s inner-city streets, with three trips out of town looking for some winding country roads.

No doubt if we were more restrained with our throttle application, we could have kept that fuel consumption figure down, but a sub-12L/100km result is still great for a performance car.

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. 

Let me be clear; driving the M2 CS is a simply sublime experience.

The M2 was always close to the top of the best modern M cars, and the CS simply cements its position as the king.

Step inside and the bucket seats and Alcantara steering wheel make sure you know you are in something special.

Push the red starter button and the engine comes to life, with a racy growl from the new exhaust system that immediately brings a smile to your face.

Out on the open road, the adaptive dampers fitted to the M2 CS do a good job at soaking up bumps and road imperfections, but don’t expect it to suddenly become a comfortable and cosseting cruiser.

The ride is firm in all settings, but dial it up to ‘Sport Plus’ and comfort really takes a hit, especially on the uneven inner-city roads of Melbourne, with its criss-crossing tram tracks.

Escape the unkempt roads of the city for the smooth blacktop of the country, though, and the M2 CS really flexes its handling prowess.

The Michelin Pilot Sport Cup 2 tyres fitted as standard also help in this regard, and while the rear end will step out with 331kW pushed through them, if you want to stick to the racing line and clip that apex, the M2 CS is a more than willing participant.

The suspension isn’t the only thing that can be changed, however, with steering and engine adjustments also available.

We found the best setting to be maximum-attack mode for the engine and suspension, while keeping the steering in its lightest setting, and even with the steering weight turned way down, the feedback and feel from the road is enough to communicate exactly what the M2 CS wants to do.

BMW has definitely nailed the feel of the M2 CS, which almost eggs you on to go faster and faster.

When things get a bit too furious, it is also comforting to know that the massive 400mm front discs and 380mm rear discs with six- and four-piston callipers respectively are more than up to the task of scrubbing speed.

I only wish I could have explored the capabilities of the M2 CS in the more controlled environment of a racetrack, because out on the open road, the M2 CS definitely still feels like it has so much more to give. And everything about this car just screams Race Track Time. Loudly.

The BMW M2 CS has not been tested by ANCAP or Euro NCAP and as such does not have a crash rating.

The car it is based on, the 2 Series, is also unrated, although the M2 CS differs wildly from the rest of the small coupe range.

Safety systems include front and rear parking sensors, automatic headlights, a reversing camera and cruise control.

Don’t expect autonomous emergency braking (AEB), blind-spot monitoring and lane-keep assist here, let alone rear cross-traffic alert or traffic-sign recognition.

Sure, the M2 CS is a track-focused special, but its also lacking some crucial safety features you’d expect out of any new car, and particularly one at this price point.

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. 

Like all new BMWs, the M2 CS comes with a three-year/unlimited-kilometre warranty, which falls short of Mercedes’ benchmark five-year/unlimited-kilometre offering.

Scheduled service intervals are every 12 months or 16,000 kilometres, whichever comes first.

Buyers can opt for a ‘Basic’ or ‘Plus’ service plan that covers the car’s first five years, priced at $2995 and $8805 respectively.

The ‘Basic’ plan covers oil changes, air filters, brake fluids and spark plugs, while the ‘Plus’ service adds replacement brake pads and discs, wiper blades and clutch.

With an annual cost of $599 or $1761 for maintenance, the M2 CS is actually pretty affordable to service.
