the Z4 Coupé M

The BMW Z4 M Coupé is a sports car for very special moments – moments the driver may well experience every kilometre, every mile on the road. Uncompromising, purist, and extremely powerful, this two-seater offers an unparalleled experience of undiluted dynamism both in everyday traffic
and on the race track. Without doubt, its prize-winning 3.2-litre straight-six M power unit developing maximum output of 252 kW/343 hp offers performance of the highest conceivable standard.
Over and above the sheer power of the engine also borne out by maximum torque of 365 Newton-metres or 269 lb-ft, the BMW Z4 M Coupé stands out in particular through its chassis and suspension designed and built to
convey enormous power safely and smoothly to the road. Indeed, the unique character of this equally unique sports car is expressed most convincingly
by its high standard of agility and spontaneity in responding to all of the driver’s commands.
While obviously being closely related to the BMW Z4 M Roadster, this
fixed-roof two-seater goes its own way also in its design and styling. The low and sleek curvature of the roof typical of a coupé and the striking look
of the car from the side make this new model unmistakable at first sight.
The BMW Z4 M Coupé is now bringing to life the Concept Car presented
by BMW at the 2005 Frankfurt Motor Show in its most sporting and dynamic rendition. A great wish and sincere hope expressed by many sports
car enthusiasts everywhere is therefore now becoming reality faster than expected. Entering the market at the same time as the BMW Z4 Coupé 3.0si, the BMW Z4 M Coupé is the most impressive proof of the huge
dynamic potential and performance this new model variant is able to offer.

High-speed power unit for incomparable performance.
BMW’s new two-seater is powered by the same prize-winning 3.2-litre straight-six M engine also featured in the BMW M3 and the BMW Z4 Roadster. The engine’s performance figures are indeed impressive at very first sight: 3,246 cc displacement, 252 kW/343 hp maximum output at an
engine speed of 7,900 rpm, maximum engine speed of 8,000 rpm. And no
less than 80 per cent of the engine’s maximum torque of 365 Newton-
metres or 269 lb-ft is available at the driver’s request from just 2,000 rpm.
Output per litre is 77.8kW or 106 hp, giving the BMW Z4 M Coupé a power-to-weight ratio of just 5.6 kilos or 7.6 lb/kW. Acceleration to 100 km/h comes in 5.0 seconds and top speed is limited electronically to 250 km/h or 155 mph.


The pleasure of shifting gears six times over.
The concept of a high-speed engine is particularly impressive whenever the torque available is converted into optimum thrust and power on the road by a short overall transmission ratio. And precisely this is what the BMW Z4 M Coupé has to offer, with its six-speed manual gearbox laid out for optimum performance throughout the engine’s entire gearshift and
speed range. Short gearshift travel, precise action of the shift lever, and close increments between the six gears – these are the typical features of this outstanding transmission.

Optimum conditions for perfect suspension.
The superior engine and drivetrain of the BMW Z4 M Coupé are matched
by an equally superior high-performance suspension. In its basic concept, the suspension is identical to that of the BMW Z4 M Roadster, but has nevertheless been geared specifically to the particular requirements of the fixed-head model. Just how perfectly all the car’s components harmonise
with one another is clearly proven by the BMW Z4 M Coupé on the Nordschleife, the Northern Circuit of Nürburgring, where the Z4 M Coupé outperforms the lap times of even the BMW M3 and the BMW Z4 M Roadster.

The chassis and suspension of the BMW Z4 M Coupé is identical in many respects to the chassis and suspension of the BMW M3, with a wide range of shared components. One example is the M differential lock on the rear axle, while the highly effective 18-inch compound brake system comes straight from the BMW M3 CSL. BMW’s DSC Dynamic Stability Control, in turn, supplements the suspension with its significant safety reserves whenever
the going gets critical.

When do they plan on releasing it? I am seriously interested, I used to own an M Coupe, one of the best M's ever, in fact better than any M3 I ever owned including the E46 M3, intimidates more than my E60 M5. Really regret selling it.
However, I don't think it looks as special as the one before it. I searched for a low mileage but with no luck, anybody know of a pristine condition under 5,000 km ?? Maybe the new one.

PS. What happened to the cool alloys of the concept?!?!?
