The BMW Z4 E85, produced from 2003 to 2008, is a two-seater roadster renowned for its sporty handling, sleek design, and powerful engine options. The model you're inquiring about, the 2009 Z4 E85, represents the final year of production for this generation. While technically belonging to the E85 series, the 2009 model year underwent a significant mid-cycle refresh, receiving a revised front fascia with a more aggressive look, updated interior trims, and slightly revised engine tuning.

The Z4 E85, known for its engaging driving experience, offered a range of four-cylinder and six-cylinder engines, all mated to either a six-speed manual or a six-speed automatic transmission. The engine choices ranged from the base 2.5i model with 192 horsepower to the potent 3.0i model generating 255 horsepower. The top-of-the-line Z4 M, powered by a 3.2-liter inline-six engine producing 330 horsepower, offered an even more thrilling driving experience, thanks to its exceptional handling and powerful engine. The Z4 E85 was built upon BMW's E46 3 Series platform, sharing the same underpinnings as the legendary E46 M3. This platform provided the Z4 with a solid foundation, delivering precise handling, responsive steering, and agile performance. The car's lightweight construction further enhanced its agility, making it a joy to drive on winding roads.
