FRANKFURT HOME
BMW will show a lightweight M3 adorned with its
celebrated CSL nameplate at this month’s
Frankfurt show. Built by BMW’s M division as part
of a study of lightweight materials, the car is a
one-off with no production potential, the company
says.
It weighs 2850 pounds, undercutting the standard
M3 by some 440 pounds, thanks to carbon fiber
roof, doors, trunklid, front air dam and exterior
mirror housings. Inside, the leather bucket
seats are replaced by dual hardshell racing pews
and the rear seat has been removed. Polished
carbon fiber trims the doors, console, dashboard
and steering wheel and the rear window is of
thinner glass. Parts of the floorpan and rear
bulkhead are made of a honeycomb sandwich
material typically used in aerospace
applications.
A beefed-up 3.2-liter inline six with revised
intake and low-friction internal components is
rpm-limited at 8200 rpm, up 200 rpm from stock.
Expect a 370-hp output, up by 27 hp, using
European figures. The combined weight loss and
power gain suggest the CSL carts only 7.7 lbs/hp
vs. the standard M3’s already impressive 9.6
lbs/hp. BMW made no acceleration claims, but
calculations suggest 0-60 mph in around 4.5
seconds.
