Founded in 1997, the British manufacturer Radical Sportscars produces small, rear-engine, lightweight, tube-frame open-cockpit sports-racing cars. The use of motorcycle engines helps keep the cars light and nimble. Near the top of the Radical range is the SR8 V8, which once owned the overall lap record at the Nurburgring’s legendary 13-mile, 73-turn Nordschliefe. With 350+ horsepower and 1,320 pounds (dry; all-up weight including driver and all fluids of 1,750 pounds) the performance of this nimble two-seater is little short of stunning. The 2.6-liter Powertec RPA, which boasts a rev limit of 10,500 rpm, is a V8 based on the four-cylinder Suzuki GXXR1300 architecture. A pair of twin-cam, four-valve, four-cylinder Suzuki cylinder heads and blocks are installed at a 72-degree angle on a purpose-built billet crankshaft and custom-cast light alloy dry-sump crankcase. Appropriate accessories are added and the result is a very compact, lightweight, engine. The output from this powerful and surprisingly economical engine is transmitted through an AP racing clutch to a six-speed Quaife sequential transaxle with torque-biased limited slip. The SR8 chassis features 280 mm vented disc brakes front and rear, double-wishbone suspension and triple- adjustable shocks. Aerodynamic features include adjustable front splitter and dual-plane rear wing.
Raced in more than 20 race series around the world, including the Porsche GT3 Cup Challenge USA the Porsche Mobil 1 Supercup in support of the FIA Formula One World Championship, the Porsche 911 GT3 Cup is the world’s most produced and most used GT race car. As such the Porsche GT3 Cup has been the vehicle that launched the professional careers of sports car champions like Sven Müller, Philipp Eng, Richard Westbrook, René Rast, Nicki Thiim, Earl Bamber and Jörg Bergmeister. With its potent, aluminum 4 liter flat 6 installed in the rear of its 1200 kg chassis, the Porsche 911 GT3 Cup is a demanding car to master, but one which delivers ample rewards to those who do.
The Ford Mustang carries on a long tradition of Ford involvement in Supercars competition. Introduced in time for the 2018 season, it’s already claimed back-to-back drivers’ championships in the capable hands of DJR Team Penske driver Scott McLaughlin. DJR used the Mustang to claim its 100th victory in Supercars competition in 2019, and will look to score yet another championship for 2020. Powered by a 5.0 liter engine, Supercars can produce upwards of 635 horsepower. They can accelerate from 0 to 100 km/h in 3.2 seconds, and hit a top speed of nearly 300 km/h. Australia’s premier racing category announced its Gen2 spec in December 2014, and adopted it in time for 2018 season after three years of development.
Few automotive manufacturers are as revered as Porsche, and many drivers will take any opportunity they can get to climb behind the wheel of one of the brand's iconic vehicles. Enter the 718 Cayman GT4 Clubsport, which combines 425 horsepower of Porsche performance with the nimble, approachable GT4 platform. The result is a highly popular sports car raced the world over, from single-class championships to the multi-class IMSA Michelin Pilot Challenge (where it makes its home on iRacing). Responsive in its handling and a whole lot of fun, it's easy to see why the 718 Cayman GT4 Clubsport is also popular as a track day car.
TCR racing has exploded in popularity around the world over the past few years, and the Audi RS 3 LMS has proven to be one of the class? most popular cars. Utilized by drivers on four continents, the RS 3 LMS found success quickly after its debut and was voted "TCR Model of the Year 2018" among vehicles from 12 manufacturers. Light and quick, the Audi RS 3 LMS produces up to 350 horsepower from its turbocharged two-liter powerplant. Sequential shifting and a quick 0-60 time mean that this front-wheel drive touring car produces plenty of exciting action, no matter where or when it?s racing.
The newest Mazda MX-5 embodies the classic top down, sports car characteristics that have made previous generations of MX-5s genuine classics: an engaging blend of power, nimble handling and comfort in an affordable package. iRacing is proud to have contributed to the design and development of the MX-5 which, like its predecessors, quickly became the world’s most raced production car with the Battery Tender MX-5 Cup in North America and similar series in Europe and Asia. Each year the international Mazda MX-5 competition culminates in the crowning of the Global MX-5 overall series champion during the Global Finale at Mazda Raceway Laguna Seca.
