Radical Motorsport has introduced their new SR10 XXR, an upgrade to its popular SR10. “The SR10 XXR has the XXR line’s inspiration of design and engineering upgrades, mated to the SR10’s acclaimed, long-life 425 bhp turbocharged 2.3-litre unit by Radical Performance Engines. Most noticeable for the SR3 XXR is its new front louvres, created for better aerodynamics at high speed, reduced understeer and improved cooling efficiency. Creating enhanced stability through corners and at speed, the SR10 XXR is also fitted with the popular LMP-inspired ‘central fin’ feature from the SR3 XXR, alongside new lightweight alloy wheels and high-intensity front DRL light clusters; all as standard. For drivers looking for even more weight reduction, a brand-new carbon splitter and diffuser package is available as a cost option.”

Both SR10 XXR and SR10 models with the ‘XXR Evolution Pack’ will continue to be eligible in international Radical Cup championships within the ‘Platinum’ classes.

The updated SR10 XXR is available to order now through Radical Motorsport’s global dealer network, operational through over 30 dealers in more than 20 countries. Production will begin Spring 2023. More information can be found here:

Autosport writers look at the new national racing championships to watch out for in 2023. “Despite the current financial climate, there’s a multitude of new categories being launched in national racing this year. Here’s what to expect from the newcomers onto the scene.”

The FIA has announced that the Performance Factor, or Pf, the new classification methodology for Hill Climb cars, is to be expanded. Initially restricted to Category 1 production class cars, the Pf will soon be extended to prototypes and single-seaters. Pf will initially be applied to Category 2 cars on a trial basis in the 2023 European Hill Climb Championship before full integration into the regulations in 2024.

The Performance Factor is a method of using easily measurable technical characteristics to give cars a Pf value which is used to classify the cars into different groups. Competitors input data about their car that represents the factors affecting the car’s performance. These factors, racing weight, engine, aerodynamic, transmission and chassis parameters are then used to create the Pf value.

The new 2023 version of the Pf for Category 1 will be available online via The new version will require all drivers to obtain a technical sheet for their car, recognizable by the code Y4 which will be associated with the Pf ID number.
