2026 Caterham Seven 620S Specs & Performance

The 2026 Caterham Seven 620S is a lightweight sports roadster built around a supercharged 2.0-liter inline-four gasoline engine producing 310 hp and 219 lb-ft of torque. Rear-wheel drive and a 5-speed manual transmission accompany a 3.4-second 0–60 mph time and 149 mph top speed, while the DOHC 16-valve Ford Duratec engine develops peak power at 7,700 rpm and peak torque at 7,350 rpm. With only 1,235 pounds of curb weight, the Seven 620S achieves a remarkably low 3.99 lb/hp power-to-weight ratio.

The roadster keeps its dimensions compact, with two seats, 4.2 ft³ of luggage capacity and a 9.5-gallon fuel tank. Double-wishbone front suspension and a DeDion rear axle are paired with vented front discs, rear disc brakes and 195/50R15 tires. Measuring 125.2 inches long with an 87.6-inch wheelbase, the Seven 620S is just 57.9 inches wide and 42.9 inches high. Its front-mid-mounted engine, longitudinal layout and exceptionally low weight emphasize direct, focused performance rather than conventional road-car practicality.
