THE RADICAL SR3 XXR IS JUST THAT, RADICAL! THE POPULAR TRACK CAR HAS ANOTHER EVOLUTION.

There’s a handful of small capacity manufacturers that create some amazing track-focused racecars that have amassed a cult-like following the world over. One of these is Radical Motorsport and they produce a very popular range of cars under the SR nameplate, and the car has evolved over the years with improvements to all facets to make it faster, sharper and more competitive. We know they can be ridiculously fast in the right hands, we’ve seen a few compete here in SA. In fact, one of the fastest time posted at the 2022 Simola Hillclimb was done in a Suzuki-powered Radical SR1 Prosport (with a little assistance from nitrous oxide) at the hands of well-known race driver Devin Roberston who took 3rd spot in his class with a sub-40 second run. Only a handful of cars have cracked the 40-second barrier. The SR1 is one of the older cars from Radical, and so we’re sure that in Devin’s hands the latest incarnation would be an absolute weapon. You can immediately see that the SR 3 XXR is way more advanced in terms of styling and aero, and that means under the skin there’s even more to make this the fastest and most advanced Radical to date. 

The spec list is brilliant, the SR3 XXR features revised LED lighting, an LMP-inspired central tail 'shark fin', lightweight wheels, an optional carbon fibre splitter and rear diffuser, AP Racing brakes and a multi-function steering wheel with built-in LCD display. The SR3 XXR can be had in single-seater configuration or with space for two, too. Owners have the option of Radical’s race-proven 1340cc or 1500cc 4-cylinder hand-built RPE racing spec engines and both make use of a 6-speed sequential gearbox with paddle shift and Quaife limited-slip differential. It’s the first Radical to be fitted with Radical Performance Engines' Generation 5, biofuel-ready, 232 bhp engine. There’s no word on pricing just yet, but you can rest assured it’s going to be a fair chunk of change because a rich history, years of experience and the best technologies aren’t cheap. Take a look at the full spec list below the video.

Take a look at the YouTube video that shows the previous version of the Radical in action on track, the SR XX. As you'll see, the track-focused racecar is brilliant with amazing handling, acceleration and cornering speeds, and when we eventually see the SR3 XXR in action it promises to be better in all ways: Radical SR3 XX - Gulf Radical Cup | Gulf Radical Cup
