As the first BMW Roadster with a retractable hardtop,

the two-seat Z4 will succeed both the BMW Z4 Roadster and the BMW Z4 Coupe. Setting a new standard in its segment, the Z4's hardtop opens or closes at the touch of a button within 20 seconds, and a moveable partition preserves luggage space when the top is down. With the compact two-piece aluminum roof stowed, the Z4 maintains the classic proportions of a BMW Roadster.

When the hardtop is overhead, driving is enhanced by a larger heated glass rear window, 40 percent larger side windows, increased headroom and elbowroom, as well as the performance provided by either of two inline-6 engines, each displacing 3.0 liters.

The BMW Z4 sDrive35i delivers 300 horsepower and impressive fuel efficiency from the world's first inline-6 engine to feature twin turbochargers, High Precision direct fuel injection and an all-aluminum crankcase. The 255 hp normally aspirated engine in the BMW Z4 sDrive30i model also delivers excellent refinement, performance and fuel efficiency thanks in great part to the magnesium and aluminum used to produce the exceptionally light engine, which weighs only 355 pounds.
