Jaguar will build 300 examples of a track-focused high-performance variant of its XE compact sport sedan, the SV Project 8, a car it says will be the most powerful and fastest-accelerating road car in the brand’s history.

At the Project 8’s heart is a 5.0-litre supercharged V8 shared with several other Jaguar and Land Rover models, but tweaked for 592 hp. Jag says that’s enough for a zero-to-100 km/h acceleration time of 3.7 seconds and a top speed of nearly 322 km/h.

To keep the Project 8’s 20-inch forged aluminum wheels planted on the tarmac, Jaguar crafted an adjustable front splitter, rear spoiler, and rear bumper with diffuser from lightweight carbon fibre, and fitted a flat underbody as a further aerodynamic tweak.

Even the trunk floor was reshaped to improve airflow through the rear diffuser. Taken together, Jag says the aero bits reduce lift by 205 percent and deliver more than 122 kg of downforce at speeds approaching 300 km/h.

Stopping duties are handled by a set of carbon-ceramic brakes clamped by six-piston front calipers and pressurized with race-grade brake fluid formulated to resist overheating in track driving.

Other carbon-fibre bits include the front quarter panels, lower side skirts, and the front bumper, which was designed to optimize airflow to the engine.

In North America, the sole specification is a four-seat configuration with performance front seats and heavily bolstered rear; elsewhere in the world, Jaguar will offer the option of carbon-fibre race seats with four-point harnesses retained by a hoop that displaces the rear seat.

To make the Project 8 a little more special, Jaguar is also offering buyers the chance to have their cars painted in one of 10,000 bespoke paint colours, along with a variety of accent colours that can be applied to the brake calipers, mirror caps, and aerodynamic components.

The XE SV Project 8 will make its official debut June 29 at the Goodwood Festival of Speed. Jaguar Canada has yet to announce its price for the car, but in the U.S. it goes for more than $192,000.
