2009 BMW Z4 Roadster spy shots

The 2009 BMW Z4 Roadster will make its official debut at next January’s 2009 North American International Auto Show in Detroit. Carscoop caught the car testing with minimal exterior camouflage.

The car will feature a two-piece retractable hardtop. The future Z4 carries over the overall styling and sexy proportions of the current Z4. On the interior there will be the same architecture as before though it appears that the dashboard has a more upscale feeling.

The Z4 will also feature BMW’s latest iteration of the iDrive that was first introduced in the new 7-Series and the facelifted 3-Series.

Under the hood BMW placed the Bavarian company’s highly acclaimed 3.0-liter twin-turbo inline-six, but there will also be 2.5- and 3.0-liter naturally aspirated six-cylinder engines while in most European countries the Z4 will be offered with an entry-level 2.0-liter 4-cylinder petrol engine.
