Jaguar releases the Speed Pack for XKR coupe

Jaguar will unveil the latest dramatic evolution of its supercharged XKR coupe at the Geneva Motor Show in March. This XKR delivers a significantly raised maximum speed – up to 280 km/h from 250 km/h, even though it is still electronically limited. By raising the “allowed” maximum speed the supercharged 5.0 has extended its sporting credentials taking it even further into supercar performance territory.

Speaking of supercars, a bold example is the Bentley Continental Supersports Convertible with 630PS (463kW) twin-turbocharged W12 engine which is the fastest, most potent drop-top Bentley ever built: 0-100km/h in 4.2 seconds and a top speed of 325km/h is a clear proof of that. It is also the fastest four-seat convertible in the world.

The uprated Jaguar XKR has 510PS and 625Nm of torque at disposal and it has always had the potential to reach speeds far beyond its original electronically limited maximum. The new Speed Pack is basically the engine and transmission recalibration.

Still it allows demanding customers to release some of that potential and give them control of the fastest Jaguar XK made to date. To ensure the XKR with Speed Pack remains stable at high speeds, the coupe uses a revised front aerodynamic splitter and larger rear spoiler to provide increased balance and a reduction in lift. The XKR’s computerised Active Differential Control is also there to fine tune the car's performance in different situations.
