The Radical SR3 is a race and sports car produced by Radical Sportscars, which has been built in Peterborough since 2002. The vehicle is considered a further development of the Clubsport 1100.
History
[edit]Designed by race car designer Mike Pilbeam, the SR3 is considered Radical's most successful model with over 1,100 units sold.[1] The vehicle was originally developed for participation in international competitions in the C3 class of the FIA. In 2009, a further developed version of the Radical SR3 was presented. For the variant called Radical SR3 SL ( for "Street Legal" ), street legal for small series vehicles is also available.[2]
In Autumn 2014, Radical presented a revised version of the racing version with the SR3 RSX.[3]
Specifications
[edit]The SR3 is extremely lightweight with a trellis chassis and weighs less than 600 kg (1,300 lb). The aerodynamic downforce allows cornering acceleration of up to 2 g at high speed. A roof or trunk is not available for the car. The racing bucket seats help to save weight. The SR3 can be ordered as left-hand or right-hand drive.[2]
The engine from the Suzuki Hayabusa 1300 is used in the SR3 RS 1300, SR3 RS 1500 Turbo and SR3 RSX. The 2.0 L I4 Ford EcoBoost engine from the Focus ST powers the SR3 SL.[4] The SR3 delivers 243 hp (181 kW). An increase in output to 304 hp (227 kW) is possible in the "Race Pack" for an additional charge. Since a heater is required to be street legal, it is installed in the SR3 SL. It also has footwell lighting and a 12-volt socket.[5]
Racing series
[edit]The SR3 can be raced in a variety of series but is best known for its use in one-make Radical Cup series run by the manufacturer or their associates. Series are run in the UK, across Europe, North America, the Middle East, Asia and Australia[6].
