Back in March, we told you that the 2009 BMW Z4 would be getting a retractable folding roof. This week some of the other blogs are picking up on the detail, with a little more information on the new Z4's powertrains.
The new Z4 is expected to offer a choice of more powerful engines. Riding on the latest 3-Series chassis, it may use the same range of four- and six-cylinder engines. The base engine in the U.S. will likely be BMW's 3.0-liter straight six, with a twin-turbo option. Britain's AutoExpress expects a diesel engine for the first time, too, and a new M version with the 4.0-liter V-8 from the M3. Stop/start powertrains should help it reduce its carbon footprint, whatever that is.
The retractable hardtop? Well, it's going to hide away in the trunk and probably will take less than 30 seconds to do so.
While the current Z4 is being built in BMW’s plant in Spartanburg, South Carolina, the new Z4 will be built in Regensburg, Germany, with production starting in late 2009.
