Jaguar’s powerful XFR sports saloon has just got even faster with the introduction of a new optional Speed Pack. Featuring a speed limiter raised to 174mph (280km/h), the 510PS Jaguar XFR Speed Pack car is equipped with revised engine and gearbox calibration to match the increased top speed. A new front aero splitter and a new rear wing distinguish the Speed Pack car. The 510PS Jaguar XFR sports saloon benefits from the same combination of eight-speed automatic gearbox and Intelligent Stop/Start allowing it to offer an unrivalled blend of efficiency and excitement.
