Caterham Seven 170 revealed as lightest production Seven to date
Caterham is famous for producing raw and featherweight driving machines, and the British marque has now unveiled its lightest production to date: the Seven 170. Priced at £ 22,990 as a kit, the new model serves as a point of departure. Entrance accessible to Caterham property, and the most accessible in terms of performance.
The Seven 170 weighs only 440kg, making it over 25% lighter than an Ariel Atom 4. The Caterham has a fraction of the firepower of an Atom, however, with its 660cc turbocharged Suzuki engine. producing 84 hp and 116 Nm of torque. The exceptionally low curb weight means the power-to-weight ratio is 191 hp / ton.
Considering the modest outputs, the Seven 170 uses a lean 155-section tire set to put the power on the road, and a rear axle suspension setup, which isn’t as sophisticated as the De Dion arrangement of the More expensive Caterham. The new model can reach 62 mph from rest in 6.9 seconds, with a top speed of over 100 mph. The Seven 170 also meets ULEZ and Euro 6 emissions standards, with a CO2 rate of 109g / km.
Buyers can choose between the more road-oriented Seven 170S or the 170R, which brings performance-oriented mechanical and cosmetic upgrades. Both models feature a 5-speed gearbox and Momo flywheel, and the 170S gets 14-inch silver Juno wheels, a windshield, full weather gear, and leather seats.
The hardcore 170S benefits from a more focused suspension setup, black Juno wheels, composite racing seats and a four-point harness. A limited slip differential is also installed for easier traction, as well as a carbon fiber dashboard. All Seven 170s come with LED tail lights and a new racing stripe design, and the car is available in four different paint colors.
The Seven 170 can be ordered as a self-build kit for £ 22,990, or as a road-ready set – although Caterham hasn’t specified the extra price for a factory build. Buyers can also opt for a financial package; it consists of a cash deposit of £ 6,312 and monthly payments of £ 199.
