2015–2026 Caterham Seven 420 Specs & Performance

The lightweight philosophy is central to the Caterham Seven 420, pairing a naturally aspirated 2.0-liter Ford Duratec inline-four with a remarkably low 1,235-pound curb weight. Its engine produces 210 hp and 150 lb-ft of torque, sending power through a 5-speed manual transmission to the rear wheels. The result is a 3.8-second 0–60 mph time and a 136-mph top speed, while the 5.89 lb/hp power-to-weight ratio highlights its performance-focused construction.

The 2015–2026 sports roadster keeps its chassis deliberately simple, with double-wishbone front suspension and a DeDion rear axle complemented by solid front discs and rear disc brakes. Two seats and 4.2 ft³ of luggage capacity provide basic practicality, while the 9-gallon fuel tank supports its compact dimensions. Measuring 125.2 inches long with an 87.6-inch wheelbase, the Seven 420 is only 57.9 inches wide and 42.9 inches high. Its front-mid-mounted, longitudinal engine and exceptionally low weight keep the focus firmly on direct, lightweight driving performance.
