2008 BMW Z4

Model strengths:
Superb handling; unique coupe body style; exclusive M model; outstanding acceleration available.




Model changes:
The BMW Z4 roadster and coupe are carried over with almost no changes for 2008. The wheels offered as part of the available Sport Package are now 18-inchers, and Stratus Gray Metallic replaces Silver Gray Metallic in the color palette.




Model value:
The 2008 BMW Z4 is a rear-wheel-drive sports car available either as a roadster or as a racy-looking, low-slung coupe. Among roadsters, the Z4 especially stands out for its better power-to-weight ratio than the Mercedes-Benz SLK, and for its more traditional soft-top convertible arrangement. The entire engine range consists of smooth, responsive inline six-cylinder engines.




The 2008 BMW Z4 roadster comes in three models (3.0i, 3.0si, and M), and coupes come in two trims (3.0si and M). Each trim brings different engines underhood. The 3.0i is powered by a 215-horsepower, 3.0L in-line six-cylinder engine, while the 3.0si gets a more powerful, 255-horsepower version of the 3.0L; both have Valvetronic variable valve lift. The top-of-the-range M includes a 330-horsepower, 3.2L six. All three models come with a six-speed manual gearbox, but a six-speed Steptronic automatic transmission with steering-wheel shift paddles is optional on the 3.0i and 3.0si.

Roadsters have a fully automatic power folding soft top, with dual-layer material, an aluminum and magnesium frame for light weight, and a heated rear window.

The Z4's proportions, with a long hood and a rearward seating position, allow for an excellent weight distribution and good dynamics for high-performance driving. The 3.0i and 3.0si models have electric power steering, while the M has a hydraulic power steering system. Coupes get a special performance-optimized suspension calibration, and all Z4s come with run-flat tires.

Inside, the Z4's interior is rather tight, as can be expected from a small two-seater, but it is appointed with luxurious upholster and trim. The dash is trimmed in either wood or brushed aluminum; 3.0i models have faux-leather upholstery inside, while the 3.0si gets "High Performance" leather upholstery in one of four color schemes. The 3.0si also adds automatic climate control, and its top, THX-certified audio system has ten speakers, seven-band digital sound processing, and two subwoofers.

M models get a number of high-performance improvements and appearance enhancements, including M Dynamic Driving Control, a system that allows the driver to change the characteristics of throttle response along with other variables. There's also a semi-dry sump lubrication system, computer-controlled variable differential lock, a heavy duty clutch, a performance-oriented version of BMW's dynamic stability control which includes dynamic brake control and cornering brake control, cross-drilled special-compound four-wheel disc brakes, and larger front and rear stabilizer bars. Inside, the M models also get Nappa leather seat trim with firmer side bolsters, automatic climate control, white-on-black gauges, a thicker steering wheel, and brushed aluminum trim.

A Premium Package brings power sport seats with memory, auto-dimming mirrors, and Bluetooth, while a Sport Package includes Dynamic Driving Control (similar to that in the M), a sportier suspension, and larger 18-inch wheels. Standalone options include a headlight cleaning system, extended leather upholstery, a navigation system, M sport seats, and heated seats.
