Tom Walkinshaw Racing (TWR) has officially unveiled the Supercat as a ‘Super GT’ restomod based on the Jaguar XJS. The Supercat’s public debut marks the revival of the TWR name under Fergus Walkinshaw, son of legendary racer and constructor Tom Walkinshaw. Touted as “the perfect tool for driving to the Nürburgring”, just 88 examples are planned for production – and the order book is open now.

“Almost 40 years after my father’s original company dominated the race track, we’ve brought the TWR name roaring back with our new Supercat,” enthused TWR director and founder Fergus. “Developed over three years, the Supercat reflects TWR’s commitment to creating an authentic, analogue Super GT for the passionate driving enthusiast.”

To deliver on these promises, TWR has completely revamped the Jaguar XJS platform and powertrain to bring modern levels of performance. Beneath the car’s bespoke carbonfibre bodywork lurks a 5.6-litre V12 engine that develops 660bhp and 538lb ft of torque. All that power is sent to the rear wheels via a six-speed manual transmission.

TWR has compensated for the dramatic power increase by stiffening the entire chassis with an integrated tubular-steel structure, alongside the carbonfibre body panels. This design not only improves rigidity but also sheds more than 100kg compared with the original XJS, bringing the Supercat’s weight down to 1605kg. TWR has yet to reveal performance figures, but we expect the Supercat to be capable of 0-62mph in around three seconds.

Chassis and powertrain upgrades are complemented by a complete overhaul of the suspension and braking system. The Supercat boasts double-wishbone suspension with active dampers at all four corners, while carbon-ceramic brakes provide plenty of stopping power. 

The car’s steering, suspension and powertrain dynamics can be tailored by the driver using five programmable drive modes, ranging from more relaxed GT to hardcore track-focused settings. TWR has also confirmed the Supercat will feature launch control and a fully programmable traction-control system.

While the exterior design is faithful to the XJS, it has been modernised by designer Khyzyl Saleem in collaboration with Magnus Walker. The Supercat design is characterised by more aggressive styling, carbonfibre enhancements and a widened stance. The aerodynamic package was fine-tuned by a former Mercedes-AMG Formula 1 aerodynamicist, resulting in eye-catching flying buttresses, integrated splitters, side-exit exhausts and a flat floor. 

“I am proud to have designed a TWR true to its racing and performance DNA,” said Saleem. “In collaborating with TWR’s exceptional team of engineers and aerodynamicists, we have created a car where every line and feature serves a performance purpose.”

The finest GT cars seamlessly combine high performance with a comfortable, luxurious interior – and the Supercat is no exception. The cabin balances comfort and heritage with carbon-backed leather seats and a modern multimedia interface supporting Apple CarPlay and Android Auto, as well as bespoke switchgear for the suspension and steering settings. The XJS’s small rear seats have been sacrificed in favour of extra luggage space.

Customer deliveries are expected to begin in summer 2025, and prices start from £225,000 plus local taxes. For more information, click here.
