You might think now that Porsche is firmly ensconced in the Volkswagen Group family, challenging Audi for overall victory at Le Mans isn't on the to-do list. Apparently, you would wrong. With 16 overall victories, Porsche has more wins at Le Mans than any other manufacturer. However, while Porsches have continued to do well in GT, the marque's last overall victory came in 1998. Plans to build a prototype early this decade were abandoned, although the V10 engine developed for it eventually found its way into the Carrera GT.

Subaru has announced its participation in the 37th ADAC Zurich 24-Hour Race (AKA the 24-Hours of Nurburgring) with a Subaru Technica International-modified Impreza STI. The WRX will be campaigning in the SP3T class (comprised of turbo'd cars with a displacement of 2.0 liters), with Kazuo Shimizu, Toshihiro Yoshida, Naoki Hattori and Koji Matsuda manning the helm during the enduro.
