Radical Sportscars today announces the SR8 RSX, the Peterborough manufacturer’s most advanced, powerful and aerodynamically-developed open racing car yet. The SR8 RSX is Radical’s new flagship racing car offering an experience closer to LMP competition than ever before – at a purchase and running cost far below the competition.
Using the latest-generation technology shared with the RXC V8 coupe including a new sevenspeed paddleshift gearbox and variable-assistance power steering, the SR8 RSX enjoys larger dimensions than the current SR8 RX, allowing for a bigger and more generously-appointed cockpit than any previous open Radical and with a greater range of driving aids and benefits than previously available.
A specification to beat all rivals
The SR8 RSX is the only car in its class and price range to offer a bespoke racing engine designed specifically for race and track use. The latest-generation RPE 3.0-litre V8 engine develops an incredible 440bhp at up to 10,500rpm, yet is also warranted for up to 40 hours between rebuilds – the equivalent of a whole season’s racing use. The SR8 RSX is also the only open race car at this price to feature a seven-speed, paddleshift transverse gearbox, with architecture identical to Le Mans prototype and top-end single-seater design.
The all-new FIA-compliant chassis will feature inboard pushrod suspension for a greater range of adjustment, and 350mm six-pot ventilated disc brakes behind either 17″ or 18″ wheel options to suit a variety of control tyre brands. The SR8 RSX is also the first open Radical to feature electrically powerassisted steering with variable assistance options.
The unique body shape draws styling cues from its sister RXC closed-cockpit model as well as Radical’s SR9 LMP2 model. Modular composite bodywork construction reduces servicing and repair costs whilst giving the SR8 RSX a contemporary, fluid look clearly distinct from Radical’s existing open-cockpit range.
Inside the cockpit, the dash is dominated by the brand-new AIM MXG dash logger, featuring a high-contrast 7″ TFT display and integrated WiFi connectivity for data download. The central instrument pod is styled seamlessly into the nose for optimum visibility and airflow. Each FIA-certified bucket seat – specially designed for the requirements of the SR8 RSX – is adjustable, perfect for trackdays and corporate as well as race use.
The larger platform allows an FIA fuel cell capacity of up to 100L, with dual dry-break refuelling an option for endurance racing.
Pre-orders for the new SR8 RSX will commence immediately with deliveries in Q1 of 2015. The SR8 RSX will be eligible for the 2015 Radical European Masters championship, Radical’s premier pan-European racing series visiting revered Grand Prix circuits across the continent and racing alongside Radical’s existing SR3 RS, SR8 RX and the new SR3 RSX models.
