Developed by Tom Walkinshaw Racing (TWR) as a street-legal, 6-unit run version of the Jaguar XJ220C (with "C" possibly standing for "Corsa"), the Jaguar XJ220S TWR (with "S" possibly standing for "Strada") is a limited-edition version of the Jaguar XJ220 supercar by Jaguar, famous for reaching a short-lived top speed record of 212.3 mph (342 km/h) in 1992, making the XJ220 the fastest production car of its time until being superseded by the McLaren F1 in 1993, with a top speed of 231 mph (372 km/h).

If the Jaguar XJ220 was the fastest production car in the mid-nineties, then the TWR supercar made from the Le Mans race version had to be astonishing. Compared to the standard XJ220, TWR’s version sported a new composite body, a more powerful engine, and went on a weight-reducing diet.
In January of 1993, Tom Walkinshaw Racing (TWR) and Jaguar Sport launched the XJ220C to compete in the GT class (Group N) of FIA motor sport. At the same time, they announced the XJ220S, a limited-production, road-going version, to comply with homologation requirements. It was easily the most radical supercar in Britain.
Although the standard XJ220 was clothed in a lightweight aluminum body, TWR’s version replaced every panel, except the doors, with carbon fiber. In doing so they added a front splitter, wider sills and an adjustable rear spoiler that gave the car an imposing edge and made the standard XJ220 look docile.
Overhauled out to 671 bhp (680 PS), TWR took the 3.5 L (3,507 cc) twin-turbocharged V6 to its limits. Combined with a weight reduction that removed the stereo, air conditioning, and heavy seats, the car could accelerate to 62 mph (100 km/h) in 3.3 seconds and reach 229 mph (369 km/h).
Only nine TWR XJ220 cars were completed and six of these were made as road-going S models. Almost all of the six cars have changed colors at least once and many made it over to America after Vik Keuylian, of Keuylian Motorcars, imported several of them.
The Jaguar XJ220S TWR, shortened to Jaguar XJ220S in-game, appears as the first Class A Elite Car, added in the June 2016 Enduro Update. It is the last car introduced in the update and the second Jaguar in Class A, after the Jaguar C-X75 about two years back in v1.4.0.
As a car intended to be at the top of Class A, the XJ220S has the highest starting rank of any Class A car, with 1520 rank points; it also has the highest MAX rank, capping at 1673 rank points; and finally, it has the second highest MAX+PRO rank in Class A during the Enduro Update, with 1772 rank points. However, while not having the best Tuning Kit impact, it doesn't have the worst either: +36 rank points. As an Elite Car, though, it can be tuned above 1772 up to 1786. Its main rivals are the Aston Martin One-77 and McLaren F1 XP-5.
The XJ220S oddly has the best starting rank in class A, even though, factually, the McLaren P1 and Ferrari LaFerrari should have better starting ranks. The acceleration on this car is very good, albeit not the best due to being outperformed by the Mosler GT3. this car has a noticeably wide turning radius, similar to the Lamborghini Aventador LP 700-4, but it might be better or worse however. The nitro efficiency of the car is incredible. Being 6/9/12, it even allows players to fire triple-nitro from start to end in certain tracks with or without extra tank. The nitro power itself, however, isn't very good, due to the fact that it excels in acceleration and top speed, it lacks nitro speed.
All in all, despite its fairly all-rounded performance, the XJ220S isn't a very useful car, as it's performance paramounts are unable to prevent the car from being outperformed by cars such as the BMW 3.0 CSL Hommage and Chevrolet 2016 Camaro SS. It however is a collectors item, as it appears in the "European Collection" and "Jaguars" collections. Being the only credit-purchasable Jaguar in the game (as well as being the most powerful Jaguar in the game), the XJ220S is usually the get-to-go car for Jaguar only events and Daily Tasks that require the player to use a Jaguar to accomplish it, though.
