The new four-door GT is undergoing the most rigorous global validation programme in Jaguar history, with 150 prototypes covering hundreds of thousands of kilometres across hot desert highways, frozen lakes and advanced virtual environments.

The demanding assessment schedule has been designed to push every system to its limits to deliver the most technically advanced and powerful Jaguar production car ever made. Jaguar claims it is an unprecedented scale of testing with the most comprehensive virtual and rig testing programme ever, prior to physical validation on the road.

Winter testing on the frozen lakes of Sweden is helping Jaguar engineers to refine the distinct characteristics of the four-door GT’s drive modes to ensure it delivers instinctive responses and calming comfort.

With more than 735kW, the new luxury GT will be the most powerful Jaguar road car ever made. Advanced all-wheel-drive tri-motor technology with Intelligent Torque Vectoring puts the power where it’s needed more quickly and precisely than ever before, for an engaging, rewarding and confidence-inspiring drive in all conditions.

Jaguar engineers will also be putting the finishing touches to a number of calibrations. Chassis systems, the all-wheel steering, a bespoke new 23-inch winter tyre, dynamic air suspension and active twin-valve dampers, all working in harmony with the propulsion torque control for supreme composure and ride comfort.

Matt Becker, Vehicle Engineering Director, Jaguar, says Jaguar has always been about driving pleasure and our new electric four-door GT will be no different. “It marks a step-change in our technical ambitions. Innovative in-house electric propulsion technologies combine with the car’s unique proportions and low centre of gravity for a luxurious grand tourer that drives like nothing else. Like a true Jaguar, it can be comfortable when you wish, is engaging to drive and, with more than 735kW, always has power in reserve.”

The sub-zero temperatures of the Arctic Circle also give Jaguar engineers the right conditions to validate its advanced ThermAssistTM technology. The pioneering onboard thermal management system reduces heating energy consumption by up to 40 per cent, and aims to recover heat to warm the propulsion system or cabin in ambient temperatures as low as minus 10°C, all while optimising the driving range, even in the coldest temperatures.

The all-electric four-door GT will make its world premiere later this year, following the Exuberant Modernist design philosophy previewed by the Jaguar Type 00 design vision.
