The V8 engine found in the XKR has been supercharged to add extra power of 550ps and 680Nm of torque to the XKR-S, pushing the top speed above 185mph.
The XKR-S can reach 60mph from standing in 4.2 seconds and is capable of going on to 100mph in 8.6 seconds.
To cope with the added power, a new aerodynamic design and a lightweight body using aluminium architecture to improve handling and efficiency.
Handling is further improved by a new suspension at the front and rear, designed to improve ‘precision, control and driver appeal’. The suspension has warranted a reprogramming for the Adaptive Dynamics system to make the most of the new set up.
"The XKR-S is a bold and exciting new model for Jaguar," said Adrian Hallmark, Jaguar’s new Global Brand Director. "We expect to attract both loyal and new Jaguar driving enthusiasts who still want the comfort, opulence and class only a Jaguar can offer, combined with inspirational performance."
The Jaguar XKR-S first appeared in 2008 as a limited edition model but the latest version is a complete reworking of the sports car.
Performance sports cars are not renown for impressive environmental figures and despite offering the lowest CO2 emissions in its class, the XKR-S still comes close to 300g/km of CO2 emissions – and a hefty road tax figure to go with it.
This won’t worry target customers of the XKR-S, which is ‘driver focused’ and aimed at performance enthusiasts, according to Jaguar.
Full details of Jaguar’s latest sports car will be unveiled on 1 March at the Geneva Motor Show.
