The Cunningham C7 concept was unveiled at the 2001 Detroit Motor Show. The C7 was built by the son and grandson of Briggs Cunningham who raced at Le Mans in the 1950s. The Cunningham company is co-owned by Bob Lutz (GM vice chairman). It was the job of designer Stewart Reed to create a 21st century of Briggs Cunningham's Le Mans racer. The Cunningham C7 was the result.
Power for the C7 comes from a 6.8 liter V12 engine producing over 500bhp.
