The 2015 BMW Z4 belongs to the second generation of Z-series that began in 2009 with E89 and is a classic roadster that truly embodies the spirit of top-down driving. Offered in three trims: sDrive28i, sDrive35i, and sDrive35is, the powerplant options include a 240-hp turbocharged 2.0-liter four-cylinder, 300-hp turbocharged 3.0-liter inline-six, and a 335-hp turbocharged 3.0-liter inline-six mated to a six-speed manual, eight-speed automatic, or seven-speed dual-clutch automatic transmission. The Z4's rear-wheel-drive layout guarantees a sleek, sporty drive. Interior features include a 10.2-inch screen equipped with BMW's iDrive infotainment system and navigation, HD radio, and Bluetooth. The sDrive35is comes standard with a sport-tuned suspension for enhanced handling. Despite its sporty design, the Z4 does not shy away from safety, touting features like BMW Assist eCall emergency services.
