Though that is the primary BMW CSL in 20 years, and there’s an enormous quantity of track-optimised tweaking to speak about, that is additionally a G82 M4. A modified one, at that. So let’s get the way it appears to be like out of the best way first…
Yes, they’re yellow lights up entrance; like the M5 CS, this new M4 will get BMW’s Laserlights as normal. That’s most likely the least contentious a part of it. Because, sure, that’s additionally crimson pinstriping for the brand new (1.2kg lighter) carbon bonnet, and for the kidney grilles (additionally now 500g lighter with fewer bars), and for the badge. Which most likely gained’t be as common as racecar-style lights, not least with the crimson persevering with for the chunkier, ‘CSL’-badged entrance splitter. And there’s lots extra apart from…
There’s extra crimson accenting alongside the perimeters (Alpine White and Sapphire Black shall be provided alongside the Frozen Brooklyn Grey pictured), wheels particular to the CSL, a carbon roof with crimson highlights, a natty built-in spoiler just like the M3 CSL and 4 monumental pipes for the titanium silencer. Note as nicely the brand new hind lights, additionally lasery – “all light functions use LED units, while the covers have intricate light threads woven into them, illuminated using laser technology” – and mentioned to be a primary for a sequence manufacturing automotive. Basically, there shall be no mistaking the CSL for any previous M4 Competition, whether or not from the entrance or again, through the day or at night time. Which, given what 100 UK consumers shall be requested to pay for the privilege of proudly owning one, can solely be a very good factor.
But there’s a complete lot extra to the CSL than lasers and crimson bits. The headline figures are mighty, this new M4 representing nothing lower than the quickest monitor automotive ever constructed by BMW. Power for the S58 3.0-litre twin-turbo straight-six is as much as 550hp, which suggests 0-62mph in 3.7 seconds and 190mph. Meanwhile, weight is down by 100kg towards a typical Comp to 1,625kg, and the Nurburgring lap time is 7:15.677 – which, for context, places it in the identical ball park because the Lexus LFA Nurburgring and Chevrolet Camaro ZL1 1LE. The CSL’s official notarised time shall be 7:20.207, the quantity for the 12.943-mile lap – nonetheless faster than a Jaguar XE Project 8, apparently, which clocked a 7:23, if a way off the 992 GT3 which the BMW will inevitably be in contrast with. It snuck in underneath seven minutes at 6:59.93.
As CSL custom dictates, BMW has gone to city with its weight reduction programme. And left it nonetheless fairly heavy, some will argue – however they’re cool modifications, nonetheless. This is now a two-seat M4, with the removing of the rear bench eliminating 21kg. Those outrageous carbon entrance buckets save one other 24kg, with one other 21kg gone because of these lighter wheels, the usual ceramic brakes and CSL-specific springs and struts. A change to lighter sound insulation trims 15 extra kilos, the titanium bits of the exhaust are price 4kg, the CFRP physique bits deduct one other 5kg and one other 4 is gone by way of the modifications to the grille, hind lights, ground mats (!) and local weather management.
Elsewhere, the automotive rides 8mm decrease than normal, with helper springs on each axles to “improve road contact in dynamic situations.” A brand new under-bonnet brace is clearly supposed to extend structural stiffness, with each engine and transmission mounted extra rigidly than normal. The entrance axle has been modified to allow extra unfavorable camber (encouraging given how nicely the Comp already responds to steering inputs), and the rear axle now advantages from ball joints rather than rubber mounts for the subframe and wheel provider management arms.
If that does not sound severe sufficient, BMW has additionally bolted the subframe to the physique with no rubber in anyway, which it says advantages stability. The traction management has been tweaked, too, now the duty of the engine administration reasonably than the DSC, which BMW says permits “the engine’s power to be adjusted with exceptional sensitivity when accelerating on slippery surfaces.” The normal tyre is a Michelin Cup 2R, 275-section on the entrance (with a 19-inch wheels) and 285 on 20-inch rim on the rear, mirroring the usual wheel dimension. A much less centered tyre possibility shall be made obtainable.
Inside the CSL is acquainted from the M4, a minimum of from the B-pillar ahead the place the solitary pair of seats are. There’s extra Alcantara and extra carbon, as befits a circuit particular, some CSL embroidery and a few M tricolour seatbelts that you simply may wish to instantly change for harnesses. But it’s recognisably M4, which is not any unhealthy factor, proper all the way down to the Head-up Display, M Drift Analyser and normal auto gearbox lever.
BMW goes to construct 1,000 examples of its flagship mannequin, with the UK set to obtain 10 per cent of the manufacturing run. Interestingly, these 100 automobiles can be found to order now – or a minimum of a few of them are – priced from £128,820. Which is about £50okay greater than an M4 Competition. Staggering, sure, however CSL custom as nicely – keep in mind the uproar when an M3 CSL commanded virtually £20okay greater than normal E46 for an additional 17hp?
No doubt the GT3 shall be talked about once more at this level, but it surely’s price remembering that you simply’ll want one other £100okay on high of the BMW’s asking value – yes, seriously – to safe a kind of proper now. Heck, even an precise M3 CSL isn’t a lot much less cash. BMW hasn’t put a precise date on a launch and deliveries for the M4 CSL, however we are able to certainly anticipate it sooner or later through the 50th anniversary yr. If we have been betting males, N24 and/or the Festival of Speed would appear like a super place to begin…
