Autoweek magazine reports in its May 29, 2006 issue that details for the upcoming BMW Z6 are beginning to take shape. Conceived as a follow-up to the Z8 and intended to compete with Mercedes' Sl line-up, the new front-engined/rear drive 2 seat sports car will be available in a roadster and a coupe version. Pricing is expected to be below the Z8's $130,000 with volume considerably higher. Still in the prototype stage, one full-size model is reported to exist in Munich and a test mule has been spotted lapping the Nurburgring. The Z6 is expected to be about the same size as the existing 6 Series and will borrow mechanical components from both the 5 and 6 Series. BMW hopes to keep weight under 3300 lbs. by increasing the use of aluminum in the chassis. 3 engines choices are planned including the new 3-liter, twin-turbocharged inline six, a 4.4-liter, twin-turbocharged V8 (read Alpina), and an updated version of the M5's 5-liter V10. Despite protestations to the contrary, styling is expected to take its cues from the Z4 (see Z-Achterbahn below). Also in the works are an entry level Z2 and a replacement for the Z4. The real question is: where does all this leave the Z8?
