Now owned & under restoration by Stefan Muecke (see Current Owners)

**ZAK-G5C-001/81
Now restored and owned by Zakspeed (see Current Owners)

ZAK G5C-0-001/80
Possibly used by Manfred Winklehock (Liqui-Moly/Nigrin) as the 'Killer Capri' in Division 1 in 1981

There were almost certainly other racing chassis built but the quantity and chassis I.D. are unknown

There were also at least two show cars built by Zakspeed. ZAK CA1981-1 is owned by Ford Team RS and housed in Cologne. There is a second show car (chassis number unknown) on display at Sinsheim Auto & Technik Museum
