Vemac RD180

The RD180 is produced in England by the Vemac Car Company, based in Chelmsford, Essex.^[3]

The vehicle is powered by a 1.8 L Honda B18C inline-four mated to a five-speed manual transmission. The vehicle is based on the Cadwell race car which Tokyo R&D designed.^[2] The car's chassis is made of steel tubing, similar to the Cadwell. It features ventilated disc brakes and double wishbone suspension.^[4]

Racing versions of the RD180 were also developed for use in the All Japan Grand Touring Car Championship, now known as Super GT. The first iteration, the RD320R, used a Toda Racing-tuned engine from a Honda NSX;^[5] successive versions would use different engines in an attempt to increase power. The RD320R started racing in 2002 and competed in over 150 races in Japan.

Changes to the Super GT rule structure were enacted in 2012 to take effect the next season; this would lead to the phasing out of JAF-GT Category C and D vehicles from competition, categories spanning prototype sports cars based on modified sports cars with few or no road-going counterparts. As a result of the rule changes, Vemac's cars are no longer able to race in the series.
