New BMW M2 Racing gets four-cylinder engine

Entry-level motorsport variant ditches straight-six for 313hp version of BMW's ubiquitous 2.0-litre unit


The latest BMW M2, as we mentioned at length on the weekend, is a very easy car to like. Much of that has to do with its lineage, of course (compact, rear-drive coupes being a quintessential part of the M car back catalogue) not to mention its broader status as a throwback (in a market chronically short of old-school, combustive charm) -  a fact that does rather highlight the importance of the angry-sounding 480hp S58 straight-six to the overall package. Remove that engine, and a key constituent of the M2’s desirability goes with it. 

News then that BMW has cast aside the 3.0-litre unit in favour of a smaller, simpler 2.0-litre four-cylinder engine for its newest and cheapest race car does seem, at first glance, like another good reason not to be cheerful in 2025. Presented during the DTM season opener ahead of a June sales launch, the M2 Racing is BMW’s latest offering to private customer teams from next year, will be priced from €98,000 (net) in the EU and distributed through selected BMW M Motorsport dealers. 

“The new BMW M2 Racing will redefine the entry-level segment. The car is affordable while offering racing teams and drivers uncompromising performance, durability, and pure driving pleasure. At BMW M Motorsport, supporting customer racing with cars that are easy to maintain, cost-efficient, and thrilling to drive is a top priority,” reckons BMW M boss, Frank van Meel. The new derivative, effectively little brother to the M4 GT4 Evo, will be built at the M2-producing factory in Mexico, earning an FIA-compliant roll cage and a drivetrain and chassis pre-assembled with the applicable motorsport parts. 

The latter comprises bespoke KW dampers and adjustable anti-roll bars with uprated brakes, alongside 18-inch forged wheels in matte black and motorsport-specific drive modes. You get a CFK roof, too, as well as a new front splitter and a tank filler neck incorporated into Makrolon rear side windows - all the usual, cool-looking racing addenda, basically. The former, under the quick-release bonnet locks and with a seven-speed ZF transmission and race exhaust, is a 313hp inline four-pot based on the B48 engine, driving through a mechanical diff lock. 

While that inevitably seems like a spiritual step down from both the road car and its big brother - as well as predecessors like the M2 CS Racing - BMW’s reasoning is typically watertight. First and foremost, as pointed out by van Meel himself, outright cost and ongoing maintenance are substantial drivers of the M2 Racing programme and the 2.0-litre motor offers significant advantages in both regards. Moreover, there are regulations to consider: in numerous competitions, engine size dictates which class you can enter - by offering a car with a lower displacement, BMW obviously expects to gain a larger market share than if it relied solely on a straight-six. 

This being the case, outright power is less of a concern, too. Factor in what we assume is a significant weight saving - the M2 Racing is said to squeak under 1,500kg; substantially less than the 1,725kg DIN kerbweight of the road car - and you can see why BMW M reckons it has found a sweet spot between performance, drivability, tyre wear and mileage. “The result is a powerful race car that combines easy operation with low running costs,” said Björn Lellmann, head of customer racing. "This efficiency makes the BMW M2 Racing particularly attractive for grassroots motorsport – and makes racing even more accessible for [buyers].”

Shame, was hoping this was going to be a road going model and a modern day E30 318iS (albeit 600kg heavier).

Interesting, but isn’t 313 hp a rather small number for a track car? That’s barely 13hp more than the new M135 and only 7 more than the recently replaced M135i

As noted in the above post, a road going 220iS might have been a worthy successor to the E30 318iS if they got it right.

It's built to regulations regarding capacity and racing class and to make it cheaper for people to buy and use for racing. I guess if you want a racy road car the M2 is still available.

So, a four cylinder turbo M2 will soon have a racing heritage to draw on. Slightly ominous.

Yeah it seems like a bit of a waste to not give it a bump in power but they haven't said what's different in this particular engine compared to the street car and there might be allowances in some race series to liberate more oomph. This car reminds me a bit of the E92 320SI but it's obviously 'round the other way where the 320SI was a homologation car for road use and this M2 is a racing car, but they were built for particular competition requirements and used smaller engines than the equivalent M cars of their day.

bloody hell, I did not realise how heavy the road car was. I always had the M2 as a 14xx kg car in my head and thought even that was not all that light for a small(ish) car.

Have to say I'd love to see M step away from the "more everything" number chasing and try a lighter simpler enthusiast model like a road going version of this. Smaller lighter wheels, fancy passive dampers, throw away some sound deadening, lightweight seats etc. More scalpel than sledgehammer. Probably still about 20 of them as it wouldn't work for pub bragging...

It's the entry level car, designed to be accessible to amateur racers. The lower power figure will help its driveability and in the right hands it will doubtless still find its way around a track quicker than any of the bigger engined road going brethren.

Makes lots of sense for a customer supply entry level race car. That weight still beggars belief though - for a stripped out race car. I guess a legacy of it being a cut and shut 4 series.

With all the 6 cylinders on the market being so bland, I'm quite keen to see more 4 cylinders back on the road. I've heard enough smooth farting exhausts to last a lifetime this last 10 years - hopefully some gruffer 4 cylinders are back on the table.

i am not sure if its the paint job, the lighting or the residual neck oil in my system but that looks longer than a regular m2, more M4 like

1500kg for a racing car with a 4 cylinder. No thanks.

Toyota have a GR86 cup series in the states. Customer cars are about the same cost as this but the GR cup car is about 300KG lighter whilst still having 250bhp N/A.

Just goes to show how bloated cars have become when a massive OEM like BMW are struggling to get their smallest RWD car down to under 1500kg!

That weight is like a medium sized estate car only a decade ago!

4 cylinders, just like the E30 M3...

I don't think the power matters much, the main thing making this fast round a track are modified suspension / geo and big sticky tyres.

It’s not a track car, or a road car. It’s a race car designed to minimise costs for teams, and simply for that I applaud it.

There are YouTubers creating 1000 plus BHP BMW six cylinder M140s and M cars, which is interesting but seems a little like just because you can, doesnt mean you should, 1300 bhp seems a little excessive.

Some of the closest racing is in Citroen C1s with less than 70 bhp, there are all sorts of series and formulas from very low power outputs like that to several hundred.

Weirdly though, road cars seem to have more power than competition cars these days, when a factory saloon car can out accelerate an F1 car, initially anyway its all got a bit weird.

Thing is, on a track a well set up competition car will be quicker than most, the very fast EV's will be done and dusted in a few laps and 1000 bhp tuner cars will likely break under track conditions, melt their brakes or just turn into a wobbly lump.

Track cars dont tend to work on the road and vice versa, this is built to do lap after lap, it will be fast enough for its class and not fall apart after three fast laps.

Be interesting to see how it laps compared to a roadgoing M2.

Quoted specs online for the GR Cup car are 228bhp and 2770lb (1256kg)

That makes it 181-182bhp/tonne.

The BMW would be 208.

The weight and power are irrelevant really as it's a race car for series like NLS and TC America so will run under Balance of Performance (BoP) anyway

The obsession with weight is as tiresome as the 0-60 traffic light GP kings.

A happy medium can be found.

More to cars than just a spec sheet.

This looks good to me and quite like the livery.
