On his way to work this morning, TheTorqueReport ’s Marc Carter caught an impromptu glimpse of the highly anticipated 2010 Z4. Definitely bigger then the current Z4, preliminary specs indicate the next-gen Z4 will ride on the 3-series platform and will most likely feature similar engine options. Like the model spotted this morning, Z4 prototypes have been glimpsed wearing retractable hard-tops, though word out of Germany confirms a soft-top option will be available as well.

The impromptu photo shoot was snapped via Carter’s iPhone, apparently during the morning L.A. grind, so cut him a break on the quality.
