23 Dec 2022|803 views
Radical has unveiled the full specification of its new Radical SR3 XXR. The new car builds on the formula of the SR3, with the XXR boosting performance, usability and durability.
SR3 models currently make up the majority of grids in the 12 Radical Cup championships around the world, with over 1,500 sold to date. The team behind the SR3 has confirmed that it has upgraded the model, and is now available to order in SR3 XXR guise.
Powering the major change is the new engine from in-house Radical Performance Engines (RPE). Delivering 232bhp from the revised 1,500cc unit, the lightweight SR3 XXR is expected to maintain its power-to-weight ratio which exceeds 345bhp per tonne.
The SR3 XXR will also have the ability to run on biofuel, making it the first Radical that can run on the sustainable fuel.
The SR3 XXR has been modified to be more agile on track, especially in pit lane stages. With a new pit limiter fitted as standard, the chance of being punished for speeding through the pit lane is eliminated.
The 'shark fin' of the SR3 XXR is inspired by LMP racers, and promises to provide aerodynamic improvement to entry and mid corner stability An LMP-inspired central tail 'shark fin' will deliver a notable aerodynamic improvement to entry and mid corner stability. The SR3 XXR is also differentiated by its lightweight wheels in a new design, alongside high-intensity DRL lights.
With the increased performance, engineers at Radical Motorsport have utilised the new technical partnership for the SR3 XXR with AP Racing, to make an upgraded braking system. The new solution has improved performance through a reduction in unsprung mass and improved pedal feel.
Other improvements to the SR3 XXR's powertrain include durability updates, external gear position sensors for the gearbox, a new scavenge pump design with improved flow for the oiling system and a fuel composition sensor that allows for the use of E85 Biofuels.
