BMW Debuts Top-of-the-Line Z4 sDrive3.5is Roadster in Detroit

Enthusiasts have been waiting patiently for an M version of BMW's latest Z4 roadster, and that day has finally arrived, in everything but name. The new – if awkwardly named – Z4 sDrive3.5is is the top-of-the-line roadster from the Bavarian automaker. Unveiled this week at the Detroit auto show, it packs the company's highly-rated 3-liter twin-turbo inline-six with 340 horsepower. 0-60? 4.8 seconds. And to bring it closer to M Roadster territory, there's an M-sport appearance package available, together with a revised suspension and bigger brakes.
