Looking for the ultimate Christmas present… to yourself? Radical has released just the car for you. Boasting more power and precision than ever before, this is the popular SR3 with the dial turned up to 10. This is the SR3 XXR, Radical’s newest and maddest track weapon and it will be available early next year.
Light and powerful
Building on the SR3, the world’s best-selling purpose-built race car. the XXR benefits from an all-new engine from its in-house Radical Performance Engines (RPE). It generates 232bhp from a revised 1500cc unit. Together with its lightweight chassis, the SR3 XXR is expected to maintain its impressive power-to-weight ratio exceeding 350hp per tonne.
Joe Anwyll, Radical Motorsport CEO, said: “We make racers.’ It’s our new strapline, but it’s true and shows through in the ethos of the new SR3 XXR. This new car has been developed with valuable contributions from our dealer partners as well as current and past customers. For example, it is through listening to their experiences that we gathered they wanted a pit limiter to stop accidental speeding through the pit lane as well as the new cooling setup that significantly reduces warmup time. These factors are just examples of how we continue to enhance the enjoyment of the SR3, arguably the most loved racing car in the world.”
Powered by Motul
It can also run on biofuel, the first Radical to do so. Braking comes courtesy of AP Racing’s enhanced brakes, which further reduce unsprung mass and improved pedal feel. Naturally, as Radical’s official lubricant partner, Motul supplies all the lubricants, from engine oils right through to brake fluids.
“Motul’s lubricants are great,” said James Scott, Radical’s technical development manager. “We use everything from the brake fluid, clutch, gearbox and engine lubricants. The durability and performance have been no issue at all. When we started out with Motul it was at the same time as we brought in a new engine. For a high compression, direct-injection engines, we need to use a special oil, and we found that right away with Motul. For us, the global availability is another huge benefit of using Motul. We’re selling cars all across the Americas, Europe, and Asia. So, to have global dealerships where our dealers can stock a really good quality lubricant is key for us.”
An engineering masterpiece
James Pinkerton, Radical Motorsport Head of Research and Development and double Radical Cup UK Champion, added: “The SR3’s handling is renowned as a masterpiece so for [SR3] XXR we took the approach of evolutionary improvements across multiple areas. We looked at customer feedback as well as a list of items we’d personally like as racers. We then set about scrutinising every system on the vehicle to see where improvements could be made, whilst staying true to the SR3 formula. We’ve carried over the sidepod profile from the SR10 to improve airflow and reduce turbulent drag, and of course the new Generation 5 RPE engine is undoubtedly the star of the show.”
The SR3 XXR is Available to order now through Radical Motorsport’s global dealer network, which operates in 21 countries through 33 dealers. Production of the SR3 XXR is due to start in February 2023 with deliveries expected later the same month.
