E60 M5 CSL built by BMW for 5-series 25th anniversary

[Jason]

A one-off lightweight E60 M5 CSL was unveiled today at BMW's Nurburgring based prototype workshop. This car was built to commemorate the 5-series 25th anniversary. Albert Biermann, BMW M division's head of development summarized the car as "the M5 CSL we never built" (though we would have loved to see it earlier and available to the public).

Mechanical changes include a heavily tuned version of the M5's 5.0L V10 motor. The V10 motor has been enlarged with a longer stroke result in a total volume of 5.5L, which is the largest displacement ever featured in an official M car. The engine also now features a carbon fiber manifold, increased capacity air box and secondary oil cooler. To feed the enhanced engine, the front bumper features an extra air duct (where license plate normally attaches) to take in more air. The transmission was swapped out for the current M3's 7 speed DCT.

According to Autocar, official power and torque figures have not been released but Biermann hints the output peaks at “around 580bhp and close to 400lb ft”. That’s up from 407bhp and 348lb ft with the standard M5. No performance claims have been made for the powered-up-and-pared-down M5, but Biermann says it is “comfortably faster the standard M5’s 4.1sec 0-100km/h”.

As part of the car's weight savings diet (which shaves approximately 50kg off the standard M5's 1830kg weight), the roof is now carbon fiber, which lowers the car's center of gravity for increased handling. The interior has been stripped down for carbon fiber backed race seats up front and the rear seats were removed.

In terms of its suspension the new M5 remains close to the standard specification. “We’ve altered the mapping of the variable dampers but the geometry remains the same,” says Biermann.

As confirmed to Autocar, the new one-off M5 it has already lapped the Nurburgring in the hands of long-time BMW race driver, Claudia Huertgen, in under eight minutes, making it some 20sec faster around the legendary German circuit than the standard M5.

“It’s a lot gutsier than the standard M5,” says Huertgen, who this year drove the new Alpina M6 GT3 race car in the FIA sportscar championship. “You can sense the added drive out of corners. There’s more bottom end shove. I’m pulling over 180mph under the bridge at the Doettinger Hohe [the fastest point of the track]."

As desirable as this car may be to all of us however, this car remains a one-off and there are no plans for production.

Weight loss of approximately 50kg off the standard M5's 1830kg weight, so about 110 pounds off.

It's a one-off car and not headed for production unfortunately

I love how in German "sedan" is "limousine"

[darkphantom]

Wow, good job but how is this related to us? it's a one of a kind and we're never going to see it, let alone be able to purchase it.

This is torture I tell ya!

[gmilori]

is it me or they messed up on the bhp on the article? isnt the standard bhp around 500bhp? The E39 was 400..

[marcel b]

they write 50kg, but this cannot be. When replacing the roof with a carbon one, replacing the front seats with carbonbacked race seats and removing the backseats you hit for sure more then that. I would more go for 75kg

[stovesax08]

Is it just me or does that seem like the easy way out to lose weight? The carbon fiber roof is cool but nothing special anymore by m standards, and removing the rear seats takes away functionality. Not that it really matters, of course, as we'll never see it. Engine modifications sound cool though

[Santa34]

i would like to see some interior shots

[txusa03]

Let see some video...anyone?

It will not go into productions, but it does gives clues about that ///M guys are up to, and what can be done with the M5.

What I found interesting the most was using the current M3's DCT. That means that it will hold up under almost 600 Bhp abuse. Expect to see it (or slightly modified) in the next M5. Also, if the airbox produced some gains you might see it available as an option when they start producing the last run of M5's in an effort to sell them off before the new car hits showrooms.

I think they went overboard with the ///M striping. It's not the Batmobile.

I hope this isn't the BIG NEWS mentioned on M3Post. You can't even buy this car and I doubt there's much of a market for a 4 door track car.

[JoeyBananaz18]

as cool as this looks, i think its immensely dumb. as stated before, the "C" in CSL stands for coupe. this project should have been done on an M6. removal of the backseat? why in a sedan. again it should be an M6. CF roof? again, from an M6.

i will say that shaving 20 seconds off the standard M5's ring time is impressive. BMW may be onto something, but as far as this car goes, its one more model to park in a BMW museum next to Han Stuck's X5.

I saw that too... They're either referring to the E39 or the E60 w/o the M button pressed.
