Default What does the R stand for

I assume that the R in the XKR must stand for race which is to obvious but what else can it stand for. Same with the XKR-S and does the S stand for sport.

The "R" signifies the supercharged model of the XK.

That is why you will see the "XK" on the left side of the rear and the "R" on the right side.

On the XK, non SC model only the XK appears on the left rear.

I am not sure that it might mean "race". But would be nice to know if the "R" has any other significance other than "supercharged".

I always assumed it meant the RALLY version. Seems more logical adding the -S for Rally-Sport.

A bit more on the "R".......

The Jaguar 'R' brand

The 'R' badge adorns the flagship performance models in the Jaguar range. It denotes cars that are effortlessly thrilling, technically state-of-the-art and dramatically designed.

First engineered by Jaguar 25 years ago, the 'R' cars each have a focus on dynamic ability that heightens driver reward on the road, yet with an approach that means they are still practical for everyday use.
With a distinctive, louder soundtrack that promises higher levels of performance from start-up, the 'R' cars are designed to empower rather than overpower, adding excitement and enhancing driver enjoyment.
Acceleration is dramatic and precisely delivered, while levels of body control, steering precision and high-speed stability are significantly enhanced. Uprated aerodynamics, improved agility and a more responsive feel elevate the driving experience, while distinctive design and high quality sporting materials and finishes give the cars instantly recognisable and purposeful looks. All of which comes without compromise to the high levels of comfort and luxury that Jaguar is traditionally known for.

The Jaguar R-S models, through technical and performance upgrades, add further to the sporting specifications of the 'R' cars, while the limited edition Jaguar GT models are the ultimate vehicles, with inspiration taken from the race track to create focused, performance cars with an emphasis on dynamic ability and speed.

In the beginning…

The very first Jaguars to bear the R badge were the XJR racing cars which campaigned in the World Sportscar Championship and American IMSA series from 1983. The best-known was the Jaguar V12-powered XJR-9 in which Andy Wallace, Johnny Dumfries and Jan Lammers took victory at Le Mans in 1988, the first Jaguar win since the D-type success of the 1950s. The same year, Martin Brundle won the WSCC in his XJR-9 by a record margin, and he too would go on to win Le Mans in the closely related XJR-12 in 1990.
Jaguar's racing partner TWR had successfully campaigned the XJ-S in the European Touring Car Championship, and had built small numbers of tuned road cars inspired by its racing cars and badged XJR-S. In the midst of the 1988 season, Jaguar decided to develop the R badge officially, and established JaguarSport as a joint venture with TWR to build low-volume, high-performance, R-badged road cars. Later, it would take their design and build entirely in-house.

Now, a quarter of a century later, Jaguar can look back at a long line of fast, powerful yet always graceful R cars, and forward to future models with levels of technology and performance that those who engineered the originals couldn't have imagined.

The first XKR arrived in 1998 to a rapturous reception from the motoring press, and stayed in production for longer than any R-badged car to date. At launch it was the fastest-accelerating standard-production Jaguar ever made, and the fastest car on sale with an automatic gearbox. It used the same 370bhp, 4.0-litre supercharged Jaguar AJ-V8 as the XJR saloon, and like the saloon kept the visual clues to its performance subtle: bonnet louvres for better cooling, red badges bearing the 'supercharged' script, one-inch bigger wheels and a tiny lip spoiler at the rear. Displacement increased to 4.2 litres and power to 400bhp in 2003, and limited-run versions included the XKR100, built to celebrate Sir William Lyons' centenary, and the final XKR 4.2S of 2005.

The supercharged version of the current, all-aluminium XK boasted a 420bhp version of the 4.2-litre V8 which, when allied to the low mass of the new body, dropped the 0-60mph time to under five seconds. When the third generation of the AJ-V8 engine appeared in 2009 with 380bhp in standard, naturally-aspirated form - more power than the supercharged car had until 2003 - the R had to move the game on again. It did so with its 5.0-litre, 510PS, 461lb-ft unit that rocketed the XKR to 60mph in 4.6sec and on to a limited 155mph top speed. Low-volume special editions have included the XKR Portfolio, with its massive 400mm front discs, the biggest fitted to a production Jaguar, and the XKR 75, built to celebrate the firm's 75th anniversary, which boosted power to 530PS and top speed to a (still limited) 174mph. Just 75 were made, but it showed that the R badge could be pushed a little further still.

The Geneva motor show has always held a special significance for Jaguar. The 1961 show marked the debut of the iconic E-Type; in 2011 Jaguar marked the 50th anniversary of that occasion with the launch of another extraordinary sports car; the XKR-S. Created by Jaguar's ETO division - as was the convertible which arrived later in the year - the R-S badge signifies a level of performance above the R-badged models, and which engineers working on the first R cars a quarter of a century ago would have thought impossible to combine with the grace any Jaguar saloon or coupe should always display. The XKR-S has the same power output - 550PS - as the special-production XJ220 of 1993, an output thought shocking at the time. The XKR-S will rocket from 0-60mph in 4.2sec, and is the first series-production Jaguar to hit 300km/h. But while the performance is uncompromising, the car is largely uncompromised. Computational fluid dynamics have helped create an aerodynamic package that cuts lift by 26 per cent, and the sophisticated, recalibrated Adaptive Dynamics package provides both low speed refinement and extreme high-speed precision and stability. The XKR-S may boast some extreme figures, but at heart it is still a Jaguar. *

Hope this helps........

I like the "R". It's beats having an "M".

TL;DR version

Basically states that the previous comment about R meaning Supercharged was wrong and we still don't know why Jaguar chose the letter R or the combination of R-S.

I don't care...as long as it "starts" when cranked, doesn't leak on my BFF's new shoes, the top goes up and the top goes down (my case), and the headlights don't "fog".
Did I leave anything out?
Happy Motoring Jag fans.......

The R stands for Roids

If 'R' is'short' for something what is 'XK' short for?

Sorry, I think the 'R' stands for Righteous!

I'd say the answer is racing.

I worked for TWR / Jaguar Sport in the late 80's and early 90's. My understanding is it meant Race. Certainly for the XJR 9 and 12. The XJR 15 original project name was R9R being based loosely on the XJR 9 the first R meaning Race and the second Road.

Interesting--I had never thought of it as being a connection to the XJR7/9!

Why doesn't someone here on the forum just contact or write Jaguar directly for their definition of "R"?

I can't find anything definitive, but I always thought the 'R' stood for Roots blower (Roots type supercharger). The 'S' usually refers to either Special or Sport, in Jaguars case it seems to relate to the Sport body shape.

As per the TWR/JaguarSport text posted earlier in this thread, the first road going R was the XJ-S (XJR-S) and that didn't have a supercharger. That also means it is the first road going R-S as well!

They also produced the first XJR which was XJ40 based and initially just had uprated suspension and a few other tweaks.
