A coupe is also suppose to be coming out about a year after the vert. The race car debuted in Geneva this past week, production car is suppose to debut this summer.
Under the hood, sources say the Z4 will be powered by four and six-cylinder engines. The base model is the Z4 sDrive20i, powered by a 2.0 liter four-cylinder unit rated at 180 horsepower and 200 lb-ft of torque. The s30i features the same engine in 248 hp, 258 lb-ft guise, with the Z4 M40i using a version of the 320 hp, 340 lb-ft straight-six from the 340i. A Competition Package could be offered for the high-end Z4 which will offer an additional 40 horsepower and 30 lb-ft of torque.
Although the base model will come with a six-speed manual gearbox, higher-end versions will relay torque via an eight-speed ZF auto box. Price wise, expect the new Z4 to sell for around the same price as the last-generation model at just north of $50,000.
I've read the production version is suppose to be around 170 long, 72-74 wide, and 49 inches tall, 50/50 weight distribution, no manual.
