BMW’s M division has built a special lightweight one-off version of the E60 M5 as part of the 25th anniversary celebrations for the iconic four door saloon.
Revealed this morning at BMW’s prototype workshop at the Nurburgring in Germany, the celebratory M5 is described by M division’s head of development, Albert Biermann, as “the M5 CSL we never built”.
Among the changes brought to the new car is a heavily modified version of the standard M5’s 5.0-litre V10 engine. The highly strung, 90-degree unit has been enlarged with a longer stroke taking its capacity up to 5.5-litres, making it the largest engine to ever feature in an official M-car.
Also included as part of the engine overhaul is a carbonfibre manifold boasting a increased capacity air box and a secondary oil cooler – the latter requiring modifications to the front bumper, which gains an additional air duct in the place usually dedicated to the license plate.
Official power and torque figures have not been released but Biermann hints the output peaks at “around 580bhp and close to 400lb ft”
Channelling the added reserves back to the rear wheels is a beefed up version of the M3’s seven-speed double clutch gearbox. The Getrag engineered unit, operated via steering wheel mounted paddles or push/pull gear lever, supplants the standard M5’s sequential seven speed manual unit, offering smoother and more rapid gear shifts.
Further changes centre around the body, which receives a carbonfibre roof as part of a weight saving program that has pared a claimed 50kg from the standard M5’s 1830kg kerb weight.
Yet despite the investment that has gone into creating the new uber-M5, Biermann says it is destined to remain a one-off.
“Right now we’re concentrating on the next-generation M5. This car has been fun to develop but there are no plans for production,” he says.
Looks like you've identified the "600 hp," 9000 rpm revving, probable double clutch, 25th anniversary edition that claudia h was referring to in the other post regarding the "next" m5.
This points very strongly to the ***** of the high rev n/a engine and lays more evidence that the f10 will have the rumored 4.4 TT from x5/6m.

Nice car, what i don't understand is why go to those lenghts to build a one-off in this economic climate towards the end off production of a nice car and then have no intention of producing a short run to mark the outgoing of a good car, sort of like the e34 run of 50 ltd models. Surely will encourage buyers of what's to come with the next model.

manufacturers are always developing cars like that
there's no plans for an E90 CSL, but we see the development car on the ring from time to time
they made a one-off E39 M5 TOURING
then there where limited run
400HP E34 M5s
COUPE & VERT E34 M5s
NOW, let the games begin. NO WAY, NO HOW DOES ///M develop this bad boy as a "one off" and throw away the time, effort and development costs to show what they can do, and then go out of their way to offer a crap FI F10-F12 M5 & M6
We shall ALL REVOLT if they do not offer this updated S85 in the next gen M5 and M6.
I throw this out right NOW...I will 100% NOT purchase the next M6 or M5 unless this is the engine. You have me on record BMW, so do what you know your loyal enthusiasts expect, offer us nothing less than perfection, in the TRUE ///M fashion, a 5.5L S85!!!!!!!!!!!!
Yep i think that answers all the questions regarding the mistery 9000rpm V10 and DCC. Oh well it was nice to dream but guess tuning has just become a whole lot easier... Chip, filter and exhaust... easy 100+ BHP ye-haa!!
Should have been called SSL... sedan sport light!!
BMW M has built one-off BMW M5 CSL!
