The 2011 BMW Z4’s specs are as follows
BMW has added a few new paint finishes to the mix, however, as well as the optional M Sports Package. The sDrive35is model will offer features like 18-inch light-alloy wheels in a five-spoke pattern as standard equipment. The 2011 BMW Z4 comes in three trim levels: the sDrive30i, the sDrive35i, and the sDrive35is.
Standard interior features on the base models of the two-seat roadster include leatherette vinyl upholstery, HD radio, a leather-wrapped steering wheel, and six-way manually adjustable seats.
A six-speed manual transmission comes standard on all trims but the sDrive35is, which offers BMW’s dual-clutch seven-speed transmission. Remarkably, the high-performance version of the 2011 BMW Z4 is not as thirsty as one would expect because of its sophisticated BMW EfficientDynamics technology--As with all luxury sports cars, car insurance premiums on the 2011 Z4 are likely to be high.
For the 2010 Detroit show, BMW is bringing along a new range-topping Z4, one with a massaged engine, subtly modified looks, and a load of M Sport touches.
Transmission options number one; the sDrive35is will be available only with BMW’s seven-speed double-clutch transmission. BMW estimates a 0-to-60-mph time of 4.7 seconds—we’ve seen 4.8-second runs from a standard sDrive35i and wouldn’t be surprised if the sDrive35is can manage the task in something closer to 4.5 seconds. Top speed is electronically limited to 155 mph. What’s more, BMW expects the 35is car to match the EPA mileage rating of the 35i with dual-clutch transmission—17 mpg city/24 highway. The Z4 35is gets unique, sporty programming for its electric power steering system. We’ve derided this system in the standard car, calling it vague and lacking in feedback. Standard wheels are 18-inch five-spokes, with 19s available as an option. Interior trim is done in what BMW calls Aluminum Carbon, which supposedly renders the look of a carbon-fiber weave in aluminum.
The "2011 BMW Z4" is a two-seat retractable-hardtop luxury roadster available in three trim levels that correspond with engine choice: sDrive30i, sDrive35i and sDrive35is.

This package includes 18-inch wheels, adaptive suspension dampers, an aerodynamic body kit, increased top speed, a thicker M steering wheel and 10-way manually adjustable sport seats with power bolster adjustment.
The Cold Weather package adds to all models heated seats, a heated steering wheel, retractable headlight washers and a trunk pass-through. The Premium package adds auto-dimming mirrors, power-adjustable seats, BMW Assist telematics, Bluetooth and on the 30i, leather upholstery and automatic climate control. A six-speed manual transmission is standard and a traditional six-speed automatic is optional. EPA-estimated fuel economy with both transmissions is 18 mpg city/28 mpg highway and 22 mpg combined.
A six-speed manual transmission is standard and a dual-clutch seven-speed automated manual is optional. The dual-clutch automated manual is standard. BMW estimates a 0-60 time of 4.7 seconds. Estimated fuel economy is 17/24/19.
