BMW Z4

The BMW Z4 is all new for 2010, and the updated roadster will be ready for production later this spring. BMW gave the Z4 sleeker sheet metal, a folding hard top, and upgraded powertrains, but the biggest change could be to its price tag. Buyers looking for a new Z4 can expect to plunk down $46,575. That's a big jump from the base $36,700 of the 2008 Z4, which packed less power and less road presence. The 46 large is also exactly the same price as the Z4's nemesis; the Porsche Boxster. The 2010 model will net you a 258-horsepower inline six capable of hitting 60 mph in 5.8 seconds. The base Bimmer will also come standard with leatherette seating surfaces (upgrading to Kansas leather tacks on another $1,250).

The 306-horsepower, twin-turbo Z4 sDrive35i will cost a whole lot more, with a starting price of $52,475, including destination and handling. The 2008 Z4 M was a bit cheaper at $50,400 and carried more power, but the 2010 car's higher torque numbers make for an equally-quick droptop, as evidenced by its 5.1 second 0-60 time with the dual-clutch gear box.
