2011 BMW Z4

The 2011 BMW Z4 gets a range-topping, higher-performance model known as the sDrive35is. Many of that trim’s enhanced handling features are available on the lower trims in a new M Sport package.

Instead of futilely taking on the dynamic midengine perfection of Porsche’s Boxster, BMW went in the opposite direction toward comfort, luxury and refinement.

Trust us; it’s a lot cooler than its clunky name sounds, boasting 35 additional horsepower from the 35i’s twin-turbo inline-6, enhanced steering and an M Sport package that adds adaptive suspension dampers, 18-inch wheels, an aerodynamic exterior kit and sport seats.

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.

Standard equipment on the sDrive30i includes 17-inch wheels, adjustable sport driving settings (steering, throttle and automatic transmission if applicable), automatic adaptive xenon headlights, automatic wipers, a fully powered retractable hardtop, cruise control, leatherette premium vinyl upholstery, six-way manually adjustable seats and a sound system that includes a single-CD player, auxiliary audio jack and HD radio. The sDrive35is gets an even more powerful engine, a standard dual-clutch automated manual transmission, sportier steering and the M Sport package that is optional on the other Z4 trims. 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. The Premium Sound package adds a 14-speaker sound system with two subwoofers, satellite radio and an iPod/USB adapter. The 2011 BMW Z4 sDrive30i is powered by a 3.0-liter inline-6 that produces 255 horsepower and 220 pound-feet of torque. 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.

Side impact airbags, antilock brakes with brake assist and stability control are all standard on the 2011 BMW Z4. BMW Assist emergency telematics is optional.

The 2011 BMW Z4′s cabin is sleek and upscale. With the top raised, visibility is unmatched for a roadster thanks to the Z4′s large rear quarter windows that eliminate the typical convertible blind spots.

Even the base 2011 BMW Z4 sDrive30i is an entertaining drive thanks to its willing and exceptionally smooth 255-hp inline-6.
