Behind the wheel of Jaguar's I-Pace eTrophy race car

Mechanically, then, how do you turn an I-Pace road car into a race car? Not dissimilarly to how you’d do an internal-combustion vehicle. The interior has been thrown out, with door cards and dashboard replaced by carbonfibre alternatives. A roll cage comes in, bolted to the very extremes of the car and thereby keeping the batteries (around 600kg of them), which lie beneath the cabin floor and take up most of the space between the wheels, within its confines.

The car’s track is widened, so there’s new bodywork to cover it, including 22in wheels running Michelin Pilot Sport road car rubber, with one set intended to last each competitor a race weekend. And then there’s some aero – some designed to reduce drag, the front splitter and big rear wing intended to induce downforce – although, at the lowish speeds of a Formula E street circuit, not much of it.

How much of the eTrophy race car’s design elements could find their way back onto an I-Pace SVR road car? “As much as we can get away with,” says Jaguar design studio director Wayne Burgess.

By throwing out the insides and fitting some new, lighter bodywork, around 300kg on each I-Pace was consigned to the skip. Putting in the cage and fire suppressant and so on puts around 75kg of that back in so, for a race car, the I-Pace is pretty heavy, at 1965kg, but still well over 200kg lighter than the road car.

With the car’s powertrain remaining the same, apart from an increased drivetrain cooling capacity by opening up the front grille and losing air-con for the occupant, the I-Pace race car should feel brisk, no? Actually, no.

It’s weird. You clamber in like you would into any modern racing saloon, seated low, strapped tight. Among the controls, the gear selector remains the same, but otherwise everything in here is bespoke. There are controls on the steering wheel to adjust the ABS, the power distribution (split 50:50 or 48:52 front to rear, with the latter providing better mid- corner rotation) and things that you know will remain unfathomable with such a brief acquaintance.
