As the 2011 Z4 sDrive35is, a new version of the Z4 roadster, will soon go on sale, details have been released. The car was given several major modifications, which include a revised straight six cylinder engine with Twin Turbo Technology, High Precision Injection and the M Sports Package, complete with M Suspension. Unveiled at this year's North American International Auto Show (NAIAS) in Detroit, the new roadster will take point in the Z4 range and comes with a twin-turbo straight-six power unit that delivers 340 hp at 5,8000 rpm and 450 Nm of torque at 1,400 rpm.
Being teamed with a seven-speed Sport Automatic transmission with double clutch operation, the engine enables the Z4 to accelerate from zero to 62 mph in 4.8 seconds, with an electronically limited speed of 250 km/h (155 mph). Its standout features include the M Sport Package and the M Suspension, both of which are offered as standard on the sDrive35is.
The M Sport includes the M Aerodynamics Package (new front bumper with a horizontal trim bar in the outer air intakes finished in matt aluminum, rear bumper with specially accentuated surrounds on the exhaust tailpipes). It also has several interior modifications that consist of the M leather steering wheel with gearshift paddles, M footrest and sports seats, grey faces for the instrument cluster, M entry strips, foot-mats with colored piping and the sDrive35is model designation, as well as M interior trim in aluminum carbon. The car is offered in six paintwork colors: Alpine White, Titanium Silver, Sapphire Black, Space Grey, Deep Sea Blue and Melbourne Red metallic.
