The C20XE has seen extensive use in motorsport. Typical uses for the engine have ranged from hillclimb events, to open wheel racing categories. Despite its age, it remains the powerplant of choice for many Formula 3 teams and has most recently found acclaim in the Australian F3 scene where Tim Macrow, the 2007 Australian F3 champion, drove an Opel-Spiess powered car to claim victory. Tuned by Spiess, an F3 grade C20XE is easily capable of producing 250 bhp (190 kW) in its naturally aspirated form.
Many aftermarket tuners have further developed the C20XE for racing purposes. SBD Motorsport, an aftermarket tuning company based in the UK, developed a C20XE unit with a power output in excess of 290 bhp (220 kW).[7] QED Motorsport is another such company that have had a huge involvement with the C20XE. They developed the first aluminium block[8] for the engine giving a massive 19 kg weight saving over the standard block and the potential for 2.3 litres of capacity! QED also developed the first direct-to-head throttle bodies,[9] allowing for greater performance in highly tuned motorsport applications as well as other enhancements.[10] Typically, both QED Motorsport and SBD built engines have seen use in Westfield and Caterham vehicles competing in various hillclimb events.
The C20XE was used by the Chevrolet WTCC (World Touring Car Championship) team and the Lada WTCC team. The engine was also an option in Westfield kitcars.
The engine has a square bore/stroke and shares piston dimensions with the Bugatti Veyron (86mm x 86mm).
C20 XE = C20 LET minus turbina.
