The 2009 BMW Z4 ushered in the second generation of BMW's renowned sports car lineage. Available in two trims, the sDrive30i and high-performance sDrive35i, both offer a front engine, rear-wheel-drive layout. The sDrive30i is equipped with a 3.0-liter inline-six engine developing 255 horsepower, while the sDrive35i sports a twin-turbocharged version of the same engine, pushing out 300 horsepower. Both configurations are mated to BMW's six-speed manual transmission, with a seven-speed dual-clutch automatic available on the rowdier sDrive35i. Heightening the driving experience is a fully retractable hardtop, a first for the Z4, enabling year-round use. On the interior, the Z4 boasts upscale features like a standard 8.8-inch infotainment display with navigation, Bluetooth connectivity, and an optional 14-speaker premium sound system. Safety features include anti-lock brakes, stability control, and multiple airbags. It's a luxurious exemplar of BMW's ultimate driving machine philosophy.
