Replacing the Superlight R500 as top of the line, the 620 R continues the Seven's emphasis on light weight, accessibility, and minimalism, but pours in more horsepower and torque than any Seven has a had to handle before.
The 620 R has a new gunmetal chassis with carbon-fiber wings, roll bar, an air-flow optimized nose cone and a race-developed cooling package. The supercharged, two-liter Ford Duratec pushes 310 bhp (231 kW) through a six-speed sequential gearbox with flat-shift to give the 545 kg (1,201 lb) vehicle 219 lbs/ft (30 Nm) of torque. Top speed is 155 mph (249 km/h) with acceleration pegging 0 to 60 mph (96 km/h) in 2.79 seconds.
Up front there's wide-track front suspension with adjustable double wishbone and in the rear there’s a De Dion axle on a lower A-frame and Watts linkage. Both front and rear suspension units have high performance dampers all round, as well as disc brakes with ventilated front discs and quad piston calipers.
Inside the 620 is what Caterham refers to as “high-performance focused instrumentation and ergonomic switchgear,” which means that it’s a pretty basic layout of dials and levers and not much more. There are also carbon-fiber interior panels and dash and carbon-fiber race seats with four-point race harnesses and a Q/R Race wheel for the rack and pinion steering.
