Caterham unleash Supersport R
Called the Supersport R, it slots in just above the normal Supersport - upgrading its 1.6-litre engine to the two-litre from the Superlight R400.
It's not quite as powerful as the Superlight's, though - Caterham have knocked the power down to 180bhp where it was 210.
It's still a fair improvement over the standard Supersport though - around 40bhp more, in fact. There's more torque too - 194Nm compared to 162 - though the already-quick 0-60mph figure has only dropped by 0.1 of a second to 4.8 seconds.
You'll also get a set of posher tyres (Avon CR500s if you know your rubber), and a racier suspension setup. There is, however, still a distinct lack of ABS, airbags or other safety equipment.
There's also a limited-slip differential too - a clever setup that should allow the Caterham to apply more power to the road without spinning the rear wheels quite so much.
The cabin gets a moderate number of changes, too - moderate because there's not much in there. You will find new steering wheel, lightweight seats and a four-point racing harness though - keeping the weight low at just 535kg.
To put that in perspective, the average Ford Fiesta weighs around twice that. Interested? You'll need £27,995 - or £24,995 and a screwdriver - depending on whether you'd like to build it yourself or not.
If it were us, we'd hand over the extra £3,000 - 0-60 in 4.8 seconds wouldn't be very fun if the steering wheel fell off...
