The Z4 Coupe 3.0si is a 3.0-Liter Engine. Powerful inline-six engine delivers 255-hp of dynamic performance with Double VANOS valve regulation. 6-speed manual gearbox is carefully tuned to engine torque.
Active Knee Protection is a special airbag designed to protect front-seat occupants knees in the event of a severe impact. It also reduces the amount of dash space that would have been taken up by a knee-protection system using dash-padding only.
All Season Traction (AST), part of Dynamic Stability Control, provides better stability and control in slippery road conditions all year long - packed snow, ice, rain- or oil-slicked roads, and sandy or rough surfaces. The system continually processes data from the anti-lock braking wheelspeed sensors. Any time a rear "drive" wheel begins to lose traction, the system modifies the engine's electronic throttle and ignition timing to reduce torque. It also can act on each rear brake individually or simultaneously, as needed, to bring wheelspin under control. Dynamic Traction Control aids driving in deep snow or sand.
BMW Ultimate Service is included at no charge with all new 2007 BMWs for the first four years or 50,000 miles, whichever comes first. It includes the BMW Maintenance Program, which covers all factory-recommended maintenance and items that need replacement due to normal wear and tear; a New Vehicle Limited Warranty; four-year, unlimited-mileage Roadside Assistance, and, if the vehicle is equipped, a four-year, unlimited mileage subscription to the BMW Assist™ Safety Plan. The BMW Assist and Bluetooth® system is standard in the 5, 6 and 7 Series; optional and included in the Premium Package in all other models.
Double VANOS allows the engine to "steplessly" choose valve timing for both intake and exhaust camshafts. Electronically controlled in response to engine speed, load and temperature, Double VANOS maximizes engine response, efficiency and emission control. The benefit: more low- to medium-speed torque for strong acceleration and added flexibility for better highway performance, plus quieter, smoother engine at idle.
Dynamic Driving Control (Sports Button) activates the Sport driving mode, for crisper handling and quicker engine response on demand.
BMW is the first automaker to offer HD Radio as a factory installed option across its entire product line. Now you can tune into clear, free, CD-like sound quality on stations that are “between” the stations now broadcasting in digital FM. The system can also stream data, such as artist and song information, from radio stations that provide it.
Run-flat tires allow speeds of up to 50 mph and travel up to 90 miles after a loss of air pressure. In situations that would normally result in a flat, reinforced sidewalls help prevent the tires from collapsing or loosening from the rim.
