Here's a new review of the Caterham Superlight R600 review done on the race track. The Caterham R600 was launched back in October last year and it's the most extreme Seven ever built by the company. It comes with a 2.0-liter supercharged engine that's good for 275 bhp and 200 lb-ft of torque. Taking into account the extremely low weight of the R600, you can imagine the amount of fun you can have with it. The price of the R600 starts at £44,995, but Caterham offers the options of upgrading your R300 to the new specifications.
