A step up from the SR1, the SR3 was first launched in 2001 and quickly became a top seller. With over 1,100 units sold, it’s the “most widely produced and most successful prototype style sportscar racer in the world,” according to Radical.
In addition to boasting more power and upgraded equipment, the SR3 offers true race-ready credentials. It’s the official vehicle of the Race of Champions for the champions of F1 as well as multiple other major racing series. The SR3 also holds bragging rights for the fastest racing lap in two recent Race of Champion Events.
Entering its fourth generation, the SR3 offers more power, improved handling, and a more reliable overall build. Drivers who want to step up to true pro equipment, like an F1-style six-speed paddle shifter, will find themselves right at home behind the wheel of an SR3.
