Classic Luxury and Performance

The 2001 Jaguar XKR Supercharged Convertible is a legendary luxury sports car powered by a supercharged V8 engine, delivering strong performance and the thrill of open top driving. To further enhance its capabilities, a Stage 1 ECU remap was carried out to optimise the engine’s performance while maintaining the car’s refined character. This upgrade builds on Jaguar’s iconic engineering, unlocking additional performance from the existing setup while working in harmony with the Jaguar XKR Exhaust.

Powertrain Excellence

Under the bonnet, the XKR X100 features a supercharged 4.0 litre V8 producing impressive horsepower and torque. The Stage 1 remap recalibrates the engine management software to safely increase power and torque output, sharpen throttle response, and improve overall drivability. By optimising fuel and ignition mapping, the engine now delivers stronger acceleration through the rev range while retaining the smooth operation of the 6 speed automatic transmission and rear wheel drive system, fully complementing the Jaguar XKR Exhaust System.

Performance and Competitor Analysis

With the enhanced Stage 1 calibration, the XKR benefits from improved mid range pull and more responsive acceleration, making overtaking and spirited driving even more effortless. The remap maximises the potential of the factory supercharged V8 without compromising reliability, ensuring the car remains competitive with other high performance convertibles of its era while offering a more engaging and refined driving experience.

Exhaust System and Upgrades

The upgraded engine software works seamlessly with the XKR’s exhaust system, optimising exhaust flow and reducing unnecessary restrictions through improved engine management. By fine tuning how the engine breathes, the remap enhances both performance and the deep supercharged V8 tone, giving the car a stronger, more purposeful sound under acceleration while maintaining comfort during cruising. This results in a more responsive and refined Jaguar XKR Exhaust note that matches the car’s performance.
