Caterham Supersport R extends Caterham 7 range

Caterham has added the Supersport R to its range of ’7′ models with a 2.0 litre Duratec Ford engine delivering 180bhp. In the meantime, Caterham’s core road car business is the old Lotus 7 range of Caterhams, so it makes sense to keep that more appealing and relevant until new cars start to arrive, so we get the Caterham Supersport R as an addition to the range to slot in between the Supersport and the Superlight models. The Supersport R gets a Ford Duratec 2.0 litre engine which produces 180bhp, which doesn’t sound a huge amount, but when you consider the Supersport R weighs in at just 535kg it starts to look plenty.

Tomorrow’s world: Fiat's MultiAir engine tech

By Jesse Crosse Motor Industry 14 October 2009 16:50 Fiat this year launches what it claims is a big step forward in variable valve timing: MultiAir. It's the first time that a manufacturer has made a properly variable valve system a production reality, and will slowly be rolled out across most of Fiat's and Alfa's car ranges.How does Fiat's MultiAir vary from existing variable valve timing (VVT) systems?Current VVT systems rely on mechanical systems to open and close the valves. Engineers have long understood the benefits of changing valve opening and closing times to tweak an engine's power and emissions performance, depending on the need for power or parsimony.Valves are an engine's nose and mouth – it inhales through inlet valves and exhales through exhaust valves.
