The classic roadster is back – more powerful and more stylish than ever before. It is the BMW Z4, the only car in its segment combining classic roadster proportions with a seating position moved close to the rear axle, rear-wheel drive, with a retractable hardtop that folds in 20 seconds. The 2009 BMW Z4 Roadster receives a slew of mechanical modifications that make it sportier and easier to live with.
The new BMW Z4 offers all the driving pleasure of a BMW Roadster with particularly refined and stylish flair. Driving with the roof down, this two-seater offers a refreshingly intense experience of the sunshine and the wind rushing by – and driving with the hardtop closed it provides all the comfort of a sporting coupe in the premium segment.
To ensure driving pleasure, the new BMW Z4 is offered with two inline-6 engine displacing 3.0 liters: 300 hp in the BMW Z4 sDrive35i and 255 hp in the BMW Z4 sDrive30i ensure truly outstanding acceleration and response at all times.
Comprehensive use of BMW’s EfficientDynamics technologies serves to provide an unparalleled balance of driving pleasure and fuel efficiency. While both models are available with a manual six-speed gearbox, the Z4 sDrive35i is available also with a dual-clutch sport automatic transmission featuring seven gears. The six-speed sport automatic is available on the Z4 sDrive30i. Both sport automatic transmissions feature steering wheel-mounted paddle shifters.
Offering spontaneous power and performance, excellent motoring refinement and outstanding efficiency, the 6-cylinder naturally-aspirated engine in the BMW Z4 sDrive30i again offers the very best in its segment. Weighing just 355 lb thanks to its composite magnesium/aluminum crankcase, cylinder head cover made of a special synthetic material and lightweight camshafts with aluminum VANOS control unit, is exceptionally light.
While BMW’s VALVETRONIC engine management controls valve stroke on the intake valves, double-VANOS varies the angle of the intake and outlet valves in an infinite process. This allows particularly efficient use of fuel, providing a “beefy” torque curve and giving the engine instant response.
The engine in the BMW Z4 sDrive30i develops maximum output of 255 hp from 3.0 liters capacity at an engine speed of 6,600 rpm. Maximum torque of 220 lb-ft, in turn, comes at just 2,600 rpm.
With this kind of power, the BMW Z4 sDrive30i accelerates from a standstill to 60 mph in 5.6 seconds (with optional sport automatic in 6.0 seconds). Top speed is electronically limited to 130 mph (150 mph when equipped with the optional Sport Package).
Featuring Dynamic Drive Control as standard, the BMW Z4 enables the driver to choose between three drivetrain and suspension settings at the touch of a button.
Electric power steering and new high-performance brakes aid the Z4 Roadster's driving dynamics, while an optional Sport Package with Adaptive M Suspension uses four twin-sleeve gas-pressure dampers to automatically vary compression and rebound settings. Dynamic Drive control also adjusts the throttle response, power steering assist, Dynamic Stability Control threshold levels and, in automatic transmission gearboxes, the adaptive gearshift logarithms (Normal, Sport, or Sport Plus).
The latest generation of iDrive debuts in the Z4 Roadster, using direct selection buttons to switch between CD, radio, telephone and navigation functions. Nav information is stored on an 80 gigabyte hard drive, while music uses a 15 gigabyte internal drive. The system is displayed on a dash-mounted, folding 8.8-inch screen, and a picture of the iDrive controller on the screen intends to make it easier to navigate.
The new car is 5.8 in. longer, 0.4 in. wider, 0.3 in. lower, and the wheelbase has grown an imperceptible 0.1 in. Though not much physically larger, it has gained some weight. The Z4 has gained 200 to 300 lb across all models and now ranges from 3241 lb to 3494 lb. Some of that weight comes from the new aluminum retractable hardtop, the first for a BMW Z roadster, which BMW says can be opened or closed in less than 20 sec. The roof is controlled by a button on the center console or by your key fob when equipped with the optional Comfort Access system. BMW says the new car effectively serves as the replacement for both the Z4 coupe and roadster, although a soft top option has been rumored.
BMW says that the new Z4 has vastly increased visibility and interior space. All-around visibility is up 14% over the outgoing model, with 40% larger side windows and 52% more see-through area out the glass rear window. Inside, the increased size gives you 0.2 in. more headroom, 0.79 in. more shoulder room and 1.69 in. more elbowroom. The door openings have even increased by 1.02 in. for easier entrance and egress.
