Fresh from testing Bloodhound SSC's parachute system from the back of its F-Type R Coupe, Jaguar has unveiled a second support vehicle for the land speed record project, in the form of the XJR Rapid Response Vehicle.
Two of the brand's range-topping 543bhp limousines have been converted to house fire fighting equipment and rescue gear by Jaguar's SVO division, which normally specialises in creating bespoke vehicles for well-heeled enthusiasts.
The fully-liveried model will make its public debut at next week's Goodwood Festival of Speed, where it will be driven by Andy Green, the man charged with taking Bloodhound SSC up to 1,000mph on its record attempt.
To create what is essentially a supercharged 5.0-litre fire engine, Jaguar SVO took a long-wheelbase version of the XJR, removed the rear seats and replaced them with a mounting platform (trimmed in leather, naturally) and a full roll cage.
Attached to the platform are six steel containers, which contain the cocktail of chemicals needed to contain a fire, should the record attempt go awry. A generator has also been fitted to power the plethora of cutting tools needed to extract Green in the event of an emergency.
With a 0-62mph time of 4.4 seconds and a top speed of 174mph, the XJR is suitably endowed for a quick response to any emergency that occurs during the record attempt, which will see a human travel on land at four-figure speeds for the first time in history - hopefully.
The two XJRs will be joined by an F-Type R Coupe, which will be used as high-speed transport for medical staff.
