BMW M3 CS boosted to 630hp by Dahler

The CS felt beyond much meaningful improvement - that hasn't stopped a Swiss BMW tuner trying, though


For all the contentiousness of its design, mechanical specification and weight, the current BMW M3 is a superb sports saloon. Furthermore, if the M4 CSL wasn’t universally loved, the CS felt like another M car legend: faster and more focused, of course, while also being comfier when required as well. And, um, quite a bit more expensive. All of which means you wouldn’t expect a mad rush to modify, yet here we are…

Swiss company Dähler has had a little tweak of the flagship M3, the result being 630hp (up from 550hp) and 546lb ft (up from 479). As is often becoming the case with this S58 twin-turbo 3.0-litre straight six, not much has been required for such a substantial uplift: it’s Dähler’s Stage 1 ECU software, which retains the standard (titanium) exhaust. There’s a set of stainless steel pipes built by Dähler themselves if desired, which promises the ‘full, imposing and powerful sound characteristic.’ But both exhaust and engine tuning comply with the WLTP Euro 6d-TEMP standard, separately and combined. 

Though different wheels are offered, Dähler has kept the standard 19-/20-inch rims to ‘preserve the exclusive character of the M3 CS as a collector’s edition.’ But if you’re thinking this looks a little meaner than what’s already a pretty aggressive standard car, very good spot: excitingly, this CS has also been equipped with four-way adjustable coilovers. Which feels like quite a big undertaking given how impressive the standard setup is. And if it can better that, this will be a very special M3 indeed. 

Again built by Dähler, they offer low- and high-speed adjustment for both compression and rebound. The quite modest claim is that the coilovers ‘enhance the driving dynamics’. Those who don’t want to go the whole hog can get Dähler Competition Line springs to work alongside the standard dampers, with wheel spacers as well. They drop the car 24mm lower at the front and 3mm at the rear. Finally, it’s worth noting that this latest range of Dahler upgrades isn’t exclusive to the CS - they all fit the standard G80 M3 as well. From £50k now, don’t forget. Prices haven’t yet been released for the suspension or engine bits, though Dähler does have a range of UK suppliers for those interested. And who wouldn’t be just a bit intrigued by an M3 that looks like this with M5-besting power?

Perhaps I'm getting too fuddy-duddy in middle age but I wonder if some cars are better left alone, especially rare ones.

It might be unfair to Dahler and all the work they've put in but my emotional reaction to this is similar to when Alexandra Burke covered Leonard Cohen's Hallelujah.

That said, there are excellent covers of that song too. Here's hoping this product by Dahler is more Jeff Buckley than Alexandra Burke in that respect.

Yeah, maybe it's you getting more fuddy-duddy...

And now people aren't allowed to cover songs they like? Jesus. The sheer elitism!

See the last para; they can do the same, though maybe with more work, to a stock M3. Which brings into question why you'd choose to start with a rarer and more expensive CS, but anyway...

It's still just a car at the end of the day, so I don't see a problem with modifying it. There are bound to be people who buy them and keep them standard, so those cars will still be available if people are desperate to have a standard one in the future.

Got bored of the article. Another remap...

I do however love those wheels. Fussy and a pain to clean no doubt, but I'm thinking they might look quite tasty on my Sophistio Grey 5 series estate?!

I never noticed the arch gap was that severe on the standard car but now I've seen it, it does a look a bit odd

If I had the pleasure of owning an M3 CS I probably wouldn’t bother.

Be an impressive beast all the same!

There you go

Would love them on my M3 but don't want to be seen as a CS wannabee.

630bhp isn't enough to stay competitive with the fastest EVs. They needed up upgrade this car to at least 900bhp to help it stay relevant.

That wheel to disk ratio is just porn on a road car...

Drop the red highlights around the rim and it would be a nice motor.

Is that the thing now ? If you can't hit the EV 0-60's then the car is relevant ?

That's pretty tragic really

As for the car - The CS typically runs around 580hp so it's not a bit increase imo.

If you have issues in the trouser department and feel like you need to keep up with the Ev's than there are tuning houses pushing these cars to 1300hp + at the wheels

Precisely what I'm thinking.

Most of the recent M products seem to sit rather high at the front end.

Hey, I resemble that comment! hehe

And no one said people can't cover songs, just that the rest of us have the right to cringe if they do a st job of it. No one objects to Jeff Buckley's version.

Really I'm trying to make a point/analogy between well/poorly tuned cars and music. Articles about tuned cars that no one's driven yet are difficult to interpret to distinguish between delicate treatment by connoisseurs and overly showy chav tat. That's not the author's fault, it's just that very few people will ever drive these to find out.

Looks better as a 3 series than the coupe. Which I’m convinced shouldn’t be the case but that’s just me! Looks seem to have grown on me especially the saloon. Had a chat with a mate yesterday actually about how easily these liberate power from what is not much work. Impressive kit no doubt. I don’t think I’d be too concerned about bits being bolted on which can be taken back off it if you need to return it to factory spec. Leave the spacers off though eh! Think of the wheel bearings! biggrin
