The Forgotten C112: Testbed for the and Active Suspension

Begun in the ’60s the exciting C111 became essentially a dead end the factory dropped Wankel development. However, technology and tested on the C112 proved to be relevant for future road and we rely on many of these advances today.

The C112’s sober and clean eschewed the ‘tack-on’ styling so often found on future and current — generations of Front spoiler was automatically in concert with rear depending on the C112’s speed. placement is similar to the Sauber C11 Prototypes of the era.
