The 2007 BMW Z4 is a part of the car's first generation, bringing together the joy of open-air motoring with the pleasures of a truly sporty drive. Two trims are offered: the 3.0i and 3.0si. Both are rear-wheel-drive models, but the 3.0si is more performance-oriented, featuring a 3.0-liter I6 engine pushing out 255 horsepower, while the 3.0i offers a toned-down variant of the same engine producing 215 horsepower. The Z4 is equipped with a six-speed manual transmission with an option for a six-speed automatic. Top-notch safety features include antilock disc brakes, stability control, and side airbags. On the tech side, an optional Sport package adds a more aggressive suspension tuning and sport seats.
