BMW has taken the wraps off a new concept Z4 Coup? at the Frankfurt motor show.
The new car is a fixed-roof version of the Z4 roadster and, although a one-off creation, looks likely to make it into production.
If it does, it will look to take on the likes of Porsche's new Cayman, and BMW says that a production version of the Z4 Coup? would be designed to appeal to the driving enthusiast.
The coup? bodyshell offers better torsional rigidity than the Z4 roadster, and BMW has hinted at a shorter final drive for the production car, giving improved acceleration.
Power comes from BMW's new 3.0-litre straight-six engine, which develops 265bhp and has 232lb ft of torque.
Performance is expected to be impressive - 0-62mph will be served up in a claimed 5.7 seconds, with a limited top speed of 155mph.
The Coup?'s body and overall layout is based on the roadster's, offering two seats and a sleek coupe roofline.
BMW says that despite appearing more curved than the old Z3, the new car will swallow two golf bags.
The Concept also gets a distinctive interior, using contrasting leather and aluminium, and sits on specially developed 19-inch alloy wheels.
