After BMW will be done with the revealing of the new generation Z4 (official launch at the Los Angeles Auto Show and sales set to begin in April 2009) it will start working on a more affordable roadster. Likely called the Z2, it will be based on the 1-Series and will be revealed sometime in 2012. The base version will likely be powered by a 1.6 liter four cylinder engine that will deliver 120 hp; while the top version will offer around 210 hp.
This is ambitious considering the amount of new projects coming from BMW between now and the Z2. Some of the plans expected from BMW over the next four years include the PAS, X1 crossover, 1-Series sedan as well as new generations of the X3 and 5-Series.
