It features an RWD (rear-wheel-drive) layout with 6-speed manual transmission, Bridgestone RE050A 225/45 R18 tires at the front and 255/40 R18 at the rear. Its 0-62 MPH acceleration time is around 5 seconds flat, with a maximum speed of 155 mph. The curb weight of the Z4 is 3019 Lbs, and its fuel consumption is about 12.1L/100Km.
The BMW Z4 M Roadster E85 includes an independent McPherson coil springs anti-roll bar system in the front and an independent transverse arms coil springs system on the rear with a ventilated discs brake system on both axles. The current market value for the BMW Z4 M Roadster E85 is $14K, but the luxurious interiors and sophisticated look of this 2-seater are way above other competitors in its price range. The amazing feeling you get driving one of these roasters at full speed with the roof down is something every motorsports lover should have the chance to experience at least once in a lifetime.
