The XJ220 S TWR was one of the fastest supercars around in the 90s, with a top speed of 228mph. This was the ultimate XJ220 to have with carbon fibre panels, added splitters and an adjustable rear spoiler. The TWR packed a huge 680bhp from its twin-turbo V6 and could easily reach 0-60 within just over 3.0 seconds. There were only nine built and were made road-going versions of the S models.
