Testing 2016 Lotus Exige Sport 350 Roadster | CSR 2

The Lotus Exige /ɛɡˈziːʒ/ is a sports car made by the British company Lotus Cars from 2000 until 2021. Originally a coupé version of the Lotus Elise roadster, since the Series 3 the Exige has been the larger-engined model of the family, featuring a V6 engine in place of the Elise’s straight-four. Convertible versions of both models are available.

Revealed on 9 December 2015, the Lotus Exige Sport 350 is the replacement for the Exige S and the ultimate incarnation Lotus’ mid-engined V6 coupe. It is lighter and faster than the Exige S and is the next step on Lotus CEO Jean-Marc Gales’ ladder to recovery for the British sports car maker. The Toyota 3.5-litre supercharged V6 underneath is unchanged, though. It still produces 345 hp (350 PS; 257 kW) at 7,000rpm and 400 N⋅m (295 lb⋅ft) at 4,500rpm. However, Lotus has been through the Exige S, stripping weight wherever possible, tweaking the chassis and generally fettling the entire package. The initial plan had been to fit the Evora’s 400 bhp engine to the Exige, but in doing so it would have meant the engineers could not get the car below the 1,200 kg target weight set by Gales. And its weight loss that has been the key focus, with 51 kg taken out of the car reducing the kerb weight to 1,125 kg. The manual gearbox has been heavily revised, giving more precise and quicker shifting. The gearshift mechanism uses light weight machined and cast aluminium components which are so technically aesthetically appealing they are no longer hidden within the transmission tunnel but exposed through an open-gate design, further reducing weight.

The Roadster variant is revealed in 2016 Geneva Motor Show. Like the coupé, the car features a carbon fibre tailgate and side intakes, and there’s also a lightweight battery and engine mounts.

Racing
Several Exiges are currently in use in the SCCA Pro Racing World Challenge. An Exige GT3 and some CUP Exige race in the Supercar Challenge. An Exige has participated in the GT300 class of the 2005 Super GT Series season.

Simply Sports Cars in Australia ran an Exige Cup R in endurance racing during 2014 and 2015 at the Bathurst 12 Hour, with class wins on both occasions.

Lotus goes to many pernickety lengths to make its cars as lightweight as possible. Wafer-thin seats. Specially formed glassfibre bodywork. Even making bespoke pipes for its heater systems. Fantastically nerdy stuff. But the latest Exige to grace the Geneva motor show has taken a rather more simple, route-one approach. Can you guess? Yup, it’s the Exige Sport 350 Roadster, and it’s got no roof.

Throwing away the composite hard-top cuts a handy 10kg from the Exige 350’s kerbweight, making this supercharged, 345bhp V6 roadster an 1115kg car. And keen students of the laws of physics will already be nodding sagely at where that weight has been cut – right at the top of the car. Lower centre of gravity ahoy.

Spec the lithium-ion battery, forged alloy wheels, two-piece brakes and carbon trim and you’ll shed another 30kg – that’s 1085kg, maths fans. Not too shabby at all for a car cradling a 3.5-litre V6 behind its cockpit…
