Lotus has shown the GT4 race variant of its Evora GT430 hardcore sports car at the Goodwood Festival of Speed.
Developed and built at Lotus’ headquarters in Hethel, Norfolk, the track-prepped Evora GT4 concept is finished in a distinctive green and gold livery that pays tribute to two-time F1 championship winner Jim Clark
A decal on the side of the Evora displays the Goodwood circuit lap record achieved by Jim Clark in 1965 – 1m20.4sec. The Type 25 racer in which he achieved this time is also on display.
The 1200kg model’s 3.5-litre petrol V6 has been tuned to produce 444bhp and 376lb ft at 4000rpm, resulting in a power-to-weight ratio of 370bhp per tonne and a claimed top speed of 170mph.
Sitting on race-spec centre-lock wheels shod with slick tyres, the Evora GT4 sports an adjustable rear wing, a roof-mounted carbonfibre air intake and aerodynamics-enhancing louvres on the front wings.
The carbonfibre front bumper has been adapted to feature removable canards and brake cooling vents, while a four-vein diffuser and large ducts at the rear enhance downforce and aerodynamic efficiency.
Further weight-saving measures include plexiglass for the side windows, a carbonfibre bootlid and 12-spoke aluminium wheels.
In line with motorsport regulations, driver safety features include an eight-point roll cage, a six-point race harnesses, an emergency engine kill switch and a fire extinguisher.
Speaking at the concept’s unveiling in Shanghai earlier this year, Lotus CEO Phil Popham said: “All of our cars retain motorsport within their DNA, and almost every road car in the company’s history has raced successfully at some point.
“It’s the philosophy that Colin Chapman founded Lotus on and that we proudly continue to this day.”
Also announced at Shanghai was the launch of Lotus’s new Chinese driving academy, where newly appointed factory race drivers Cui Yue and Gaoxiang Fan will host track training days and hot lap sessions.
