The Radical SR10 iRacing launch has officially arrived, bringing a new era of turbocharged performance to the sports racer category. As part of the 2022 Season 3 build, the SR10 makes its debut as a modern, high-torque alternative to the legendary SR8. This “extreme track day” machine combines the agility of a lightweight chassis with the relentless punch of a 425-horsepower Ford EcoBoost engine, offering sim racers a driving experience that bridges the gap between GT3 endurance and high-downforce prototype racing.
Turbocharged Torque: The EcoBoost Revolution
The headline of the Radical SR10 iRacing release is the move to forced induction. At its heart sits a 2.3L RPE-Ford EcoBoost engine, custom-tuned with a Garrett G-Series turbocharger to deliver 380 lb-ft of torque. Unlike the high-revving, peaky power delivery of previous Radicals, the SR10 is all about the “wall of torque” in the mid-range. This allows drivers to hold higher gears through technical sections, relying on the turbo’s boost to pull the car out of corners. However, this power requires a disciplined right foot; the torque is enough to light up the rear tires if you’re too aggressive on the exit.
Driving the Radical SR10 iRacing car on launch day has revealed a more stable and predictable platform than its predecessors. The car feels significantly more “planted,” thanks in part to its Hewland GT3-derived six-speed sequential gearbox and automatic torque-biasing differential. While it retains the signature nimble handling that Radical is known for, the SR10 feels less like a twitchy open-wheeler and more like a refined endurance prototype. It’s a car that rewards smooth inputs and clinical precision over raw, reactive aggression.
The Physics of Downforce and Weight
One of the most impressive aspects of the Radical SR10 iRacing launch is the integration of the New Damage Model (NDM) and updated aero physics. Weighing 725kg, the car is heavier than the SR8, which translates to a greater sense of “heft” in the steering and a different demand on the braking zones. The bi-plane rear wing and composite bodywork generate massive downforce, allowing the car to “stick” in high-speed sweeps. You’ll find that the faster you go, the more the car trusts the air, but the increased weight means you must be more mindful of weight transfer during heavy trail-braking.
Mastering the Digital Cockpit
The Radical SR10 iRacing release features a high-fidelity recreation of the modern Radical cockpit. This includes the AiM Formula steering wheel with its 4.3-inch TFT display, providing real-time data on gear selection, shift lights, and lap timing. Sim racers will need to pay close attention to the tire temperature displays; the SR10’s tires are notorious for taking 3-4 laps to fully come up to temperature. Early-lap caution is essential, as the car can feel “icy” until the rubber reaches its optimal operating window.
A New Home in the Radical Esports Cup
With this launch, the Radical SR10 iRacing becomes the new centerpiece of the official Radical Esports Cup (formerly the Radical Challenge). This series has been rebranded to reflect the car’s status as a global benchmark for professional sports racer competition. Whether you’re competing in the 30-minute sprints or taking the car out for a technical endurance run, the SR10 offers a visceral and immersive experience that is unlike anything else in the sim. The turbocharged era is officially live—it’s time to see if you can handle the torque.
