2011 BMW Z4 sDrive35is Picture
BMW will top off the Z4 lineup with a new performance model called the sDrive35is.BMW will publicly unveil the new 2011 Z4 sDrive35is roadster in early January at the 2010 Detroit Auto Show. The range-topping Z4 sDrive35is features a new M Sports package that also will be offered on other Z4 variants when the Z4 sDrive35is reaches U.S. dealers in spring 2010.
The Z4 sDrive35is gets an even hotter version of the twin-turbocharged 3.0-liter inline six-cylinder that powers the current Z4 sDrive35i. BMW has hiked boost pressure and air intake flow, resulting in an increase in output from 300 to 335 horsepower and an increase in torque from 300 to 332 pound-feet. An overboost function enables the engine to deliver brief bursts of up to 369 lb-ft.
The engine is mated to a seven-speed dual-clutch transmission. BMW says the Z4 sDrive35is can gallop from zero to 60 mph in 4.7 seconds, with acceleration from rest facilitated by a Launch Control function. Top speed is electronically limited to 155 mph.
As part of the Z4 sDrive35is upgrades, BMW has reprogrammed the electric power steering to provide more driver feedback and has fitted 18-inch five-spoke alloy wheels (19-inch wheels and tires are optional).
The Z4 sDrive35is receives new M Sport upgrades as well, including adaptive suspension with electronic dynamic damping control and ride height reduced by 0.4 inch.
Other M Sport features include a thick-rimmed leather steering wheel with gearshift paddles, sport seats, gray-face instrument dials, piped floor mats, driver's footrest, doorsill strips and matte aluminum/carbon accents.
