Description

Do you want to experience real racing? The SR1 XXR is exactly what you’re looking for. This isn’t a modified road car. It’s a genuine race car designed from the factory for track use. With 188 hp and weighing just 510 kg, you’ll experience performance you never thought possible.

The SR1 XXR received a major update in 2023. RPE’s new Generation 5 engine is more reliable than ever, the design is sharper and the aerodynamics deliver even more downforce. EVO magazine awarded it 5 stars and called it “the most fun car you’ll ever drive’’.

The SR1 XXR’s biggest advantage is that you can immediately compete in official race competitions. Radical offers comprehensive training and support, so even if you’ve never raced before, you can get started quickly. The car is designed so beginners can master it, while remaining challenging enough for experienced drivers.
With just 510kg and 188hp working together, you’ll accelerate to 100 km/h in just 3.1 seconds. The SR1 XXR clocks a 2:11 lap time on Silverstone GP. That’s a seriously impressive performance that puts it in supercar territory. You’re getting all that speed and track capability without the supercar price tag.

Frequently Asked Questions

What are the running costs like?
Surprisingly reasonable for a dedicated race car. The reliable Gen 5 engine and standardized parts across the Radical range keep maintenance costs manageable. You'll need to budget for racing fuel, tyres, and regular servicing, but many owners find the total cost of ownership much lower than they expected.
Can I take passengers on track?
Absolutely. The SR1 XXR chassis accommodates both single and dual-seat configurations. You can take passengers during track days or have an instructor ride along, then easily convert to single-seat mode for competitive racing. The flexible seating arrangement makes it perfect for both learning and entertaining guests.
Is it genuinely competitive in amateur racing?
Very much so. The strict technical regulations in Radical Cup series create a level playing field where driver skill and racecraft matter more than your budget. Many SR1 XXR drivers have won championships and used their success as a stepping stone to faster Radical models or other professional racing series.
Do I need a racing license?
For track days, your regular driving license is sufficient. Racing requires a motorsport license from your national authority.
How much mechanical knowledge do I need?
Basic automotive understanding helps, but don't worry if you're not mechanically inclined. The SR1 XXR is designed for owner maintenance on routine items like oil changes and brake pad replacement.
How does it handle in wet weather?
The SR1 XXR is surprisingly capable in the wet. With appropriate tyres and the advanced aerodynamics providing consistent downforce, it remains predictable and manageable in challenging conditions.
