Nearly 80 years after the first BMW roadster went on sale, the latest has been launched in the UK. Featuring a host of innovations never before featured on a BMW of this type, the new BMW Z4 is the first to come with a two-piece, electro-hydraulically operated Retractable Hard-Top roof that can be raised or lowered in 20 seconds. The new BMW Z4 is also the first roadster to be offered with Adaptive M Sport Suspension. This system features a ride height 10mm lower than the standard car for a more dynamic drive. Adaptive M Sport Suspension also comes with electronically controlled dampers that offer three different configurations from Normal to Sport+ so a driver can fine tune the car's set-up.
The standard Drive Dynamic Control function is another BMW roadster first and allows the driver to alter the chassis configuration to suit their needs. Now the BMW Z4 has the capability to morph between comfortable yet sporty cruiser through to outright performance car. Depending on model specification, the throttle and steering response, level of ride comfort, Dynamic Stability Control response and, on automatic or Double Clutch Transmission cars, gear change times can all be altered.
|Model||Price||Power||Torque Nm||0-62||Top Speed||mpg (combined)||Emissions|
|BMW Z4 sDrive23i||£28,645||204||250||6.6||151||33.2||199|
|BMW Z4 sDrive30i||£32,660||258||310||5.8||155||33.2||199|

Transmitting the power to the road in all three BMW Z4s is a six-speed manual gearbox as standard. Customers of the BMW Z4 sDrive23i and the BMW Z4 sDrive30i who prefer the characteristics of an automatic can specify a six-speed Sport Automatic transmission featuring gear change paddles on the steering wheel. Buyers of the BMW Z4 sDrive35i can choose a seven-speed Double Clutch Transmission, again with gear shift paddles located on the steering wheel.
Increased Comfort and Practicality
The new BMW Z4 is larger than its predecessor measuring 148mm longer at 4,239mm and 9mm wider at 1,790mm, and this results in greater interior space and luggage capacity. With the roof up, headroom has been increased by 44mm while the greater car width and design enhancements have led to 20mm more shoulder room and 43mm more elbow room.
Driver visibility in the BMW Z4 has also been improved. All round visibility is up by 14 per cent while, courtesy of the four electric windows creating a larger glasshouse, side visibility is up 40 per cent. The Retractable Hard-Top roof features a glass rear window and this too improves visibility by 52 per cent.
The most recent incarnation of iDrive makes its first appearance on a BMW Z4. The optional BMW Professional Multimedia Navigation system features a hard disc drive capable of 12Gb of audio file storage and BMW ConnectedDrive functionality. A vehicle specified with this system also comes with eight programmable Favourite buttons as system shortcuts.Published 12 May 2009
