While some of you may have already seen the all-new 2009 BMW z4 Roadster, the refined droptop will be making its European debut at the Geneva Auto Salon in March. The German sports car will be powered by a sDrive 35i turbocharged 300 horsepower inline-6 cylinger engine that provides 300 ft-lb of torque at 1400rpm. Customers may also opt for a SDrive 30i engine (inline-6 255hp and 200f-lb or torque). The previous Z4 Roadster could only be paired with a 215hp or 255 hp engine. The new sDrive 35i boasts Valvetronic technology, which provides more performance and better fuel mileage. The renovated interior can be garnished with abrushed aluminum, ash grain wood trim, and multiple tints of premium leather. The best new feature on the Roadster is the hardtop roof that retracts to turn your daily commute into a daily thrill ride. The hardtop roof allowed BMW to sculp larger windows for better visibility. What makes the Z4 truly a fun drive is the Sport Button, which tunes the engine response and power steering to provide a more rugged, sensitive driving experience.
