The next stage of testing for Lotus' new electric hypercar, the Evija, has got underway at the company's famed Hethel HQ. Following extensive simulations, plus initial on-track sessions in the UK and Italy, Lotus has now rolled out the most complete version of the car built to date. Prototype #2 features customer-specification suspension, a complete EV powertrain, and full carbon-fiber body panels, plus a mostly complete interior with production-spec seats. The car also has a full hydraulic system to support the deployment of the car’s active aerodynamics.

Driving Prototype #2 during development has been Gavan Kershaw, Lotus' director of attributes and product integrity – he's basically the firm's lead test driver. Kershaw is also known as the man behind Top Gear's famous test track at the Dunsfold Aerodrome, designing each of the track's characterful corners.
"The car is in a completely pure state at the moment, with no stability control or torque-vectoring. This is so we can evaluate the fundamentals of the chassis, to create the mechanical advantage before the other layers, such as the electronics, are added," said Kershaw. "It means we can really read the car. Later we can tune what we’ve gained as a mechanical advantage as we add layers."
One of the things Lotus has been working on early in the car's development is the torque split between each of the car's four individually-powered wheels. The car is the fist all-wheel-driver car from Lotus but Kershaw, who has been at Lotus for over 30 years, said he feels "at home" in the car already.
"Lotus has always been about 'input = output', so if you do something you get a response, and that’s what we’re balancing now," he added. "It’s all about the detail so, for example, we’re validating the progressive response from the pedals. We know there’s an enormous amount of torque but drivers will only want it when they ask for it with their right foot. It’s about getting that throttle balance right."
