The Supercat features a carbon fiber body designed by Khyzyl Saleem that's 10% lighter than the original XJS. TWR added boxy wheel arches, aggressive aerodynamics, and a side-exit exhaust to give the car a more muscular look. The restomod sits on larger wheels - 18 inches in front and 19 inches in the rear, compared to the original's 15-inch wheels.
Under the hood, TWR swapped out the original 6.3-liter V12 for a bored-out 6.5-liter supercharged V12. The new engine produces 660 horsepower and 538 lb-ft (730 Nm) of torque - a massive increase from the original's 281 hp and 318 lb-ft (431 Nm). A six-speed manual transmission with launch control replaces the old three-speed automatic.
TWR made major upgrades to the chassis as well. The company reinforced it with carbon fiber and added a custom high-strength steel subframe. The suspension now uses double wishbones with active, adjustable dampers. A limited-slip differential and traction control system help put the power down through five selectable driving modes.
Inside, TWR converted the 2+2 layout to a two-seater configuration. The interior gets modern touches like a digital instrument cluster, center infotainment display with smartphone connectivity, and carbon fiber-backed leather seats. Electric seats and a larger cargo area add some practicality.
We wanted to create something truly special that pays homage to the original XJS while bringing it firmly into the 21st century,
said a TWR spokesperson.
The Supercat delivers mind-blowing performance wrapped in a stunning package that turns heads everywhere it goes.
TWR plans to convert 88 XJS cars to Supercat spec, commemorating Tom Walkinshaw's XJR-9 victory at Le Mans in 1988. The company will offer both left- and right-hand drive versions for markets in the US, UK, Europe, Asia and Middle East.
Pricing for the Supercat starts at £225,000 ($285,000) before taxes in the UK. TWR requires a £35,000 ($44,000) deposit to secure an order.
