Seven R500

The Caterham Seven R500, introduced in April 2008, represents ultimate expression of lightweight performance philosophy featuring 2.0-liter Duratec Cosworth engine producing 263 horsepower and 177 lb-ft torque in chassis weighing just 506 kg (516 kg with optional sequential gearbox). The remarkable power-to-weight ratio of 520 horsepower-per-tonne enables extraordinary performance achieving 0-60 mph acceleration in 2.88 seconds and top speed of 150 mph. The R500 utilizes special lightweight chassis with thinner-gauge aluminum body panels and carbon fiber components including dash, nose cone, front and rear wings reducing weight while maintaining structural rigidity. Optional Quaife close-ratio six-speed sequential manual gearbox with launch control provides optimal power delivery and shifting speed.

The R500 replaced earlier Rover K-series powered version, adopting more reliable and powerful Duratec Cosworth engine delivering consistent performance with strong aftermarket support. The combination of extreme lightweight construction, powerful naturally aspirated engine, advanced aerodynamics generating up to 2g cornering acceleration at high speeds, and minimalist design focused purely on driver engagement makes the R500 one of fastest accelerating production cars ever built. While lacking modern conveniences and weather protection, the Seven R500 delivers pure driving experience with performance rivaling supercars costing many times more, establishing Caterham continuing legacy of producing ultimate lightweight sports cars focused on driver involvement and track performance.
