The BMW Z4 sDrive28i Roadster will be the first BMW to get a 4-cylinder engine in the United States since the BMW 318i was offered in the early 1990s. But unlike the underpowered 1.8L mill of yore, this new 2.0L 4-banger will pack a turbocharger, helping it make 240 horsepower and 260 lb-ft of torque. The 260 pounds of twist arrives at 1,250 rpm, giving the car some urgency down low.
Fuel economy is said to be up 20 percent when equipped with the optional 8-speed automatic, the gearbox that will undoubtedly find a home in many Z4s, even if its not our choice of transmission. The base model 6-cylinder, with a 3.0L naturally aspirated engine, weighs about 3,240 lbs, a not exactly svelte number, but with the added boost, we expect the Z4 to put up respectable, but not thrilling acceleration numbers – even though this model is likely being sold to those who value “show” greatly over “go”.
