Extreme E off-road electric racing car revealed
The Extreme E off-road racing series for electric vehicles – a new venture from Formula E founder Alejandro Agag – has revealed its car design at the Goodwood Festival of Speed.
Called the ODYSSEY 21 E-SUV, the vehicle has been developed by Spark Racing Technology (SRT), which also designed the initial Formula E chassis. It was completed just last week at SRT's facility in Tigery, France, and will carry out demonstration runs on the Goodwood hillclimb this weekend.
Peak power is 550bhp, enough to get the 1,650kg vehicle from 0-62mph in 4.5 seconds on a significant gradient. The car's tubular frame, crash structure, roll cage and Williams Advanced Engineering battery will be common for all entrants.
Teams will be able to develop their own electric motor (as in Formula E) and are also permitted to modify the engine cover, bumpers, side skirts and lights in order to make the car more closely resemble production models. All of the E-SUVs will run Continental off-road tyres.
SRT's technical director Théophile Gouzin said: "Our challenge was to build a car that could face all the variations in surface and terrain that will be thrown its way, which will include gravel, rock, mud, ice, snow, water and sand.
"The ODYSSEY 21 and its performance is going to be very impressive, exceeding the power and torque of World Rally Championship and rally raid cars. The wheels are some 940mm. Wheels that size have never been utilised in anything other than two-wheel-drive racing cars before.
"Using them means we get the benefits of increased traction and traversal ability along with huge suspension travel. The torque and power density from the powertrain is also a breakthrough. We’re getting huge figures from a small package, which means lighter weight, space savings and ultimately improved economy."
Testing of the prototype is set to begin this September. SRT will then deliver 12 cars in March 2020 for group testing. The Extreme E series proper will kick off in January 2021; it's set to visit locations in the Arctic, the Himalayas, the Sahara desert, the Amazon rainforest and Indian Ocean islands.
Extreme E will use a round-robin format with two groups of six teams. The top four will progress to a knockout stage and each will go head-to-head to earn a place in the final. The off-road stages will be around six to 10 kilometres in length, with a series of virtual 'gates' to be navigated through by drivers.
The championship was launched in London in January on board the former Royal Mail ship St Helena. The vessel – which retired last year from its longstanding role ferrying supplies to the Atlantic island it's named after – has been purchased by Extreme E and is being turned into a mobile operational base for the series, with all equipment transported by sea rather than by air to reduce carbon emissions.
British adventurer and environmentalist David de Rothschild is the 'Chief Explorer' of Extreme E and will spearhead its mission to raise awareness of issues such as melting ice caps, deforestation, desertification, retreating glaciers, plastic pollution and rising sea levels.
