Dodge Challenger

By Liz Turner Motor Shows 20 March 2008 20:51 Lucky US buyers can now get behind the wheel of a Dodge Challenger for less than $20,000 (about £10k). The base model is the 250bhp 2.5 V6, described as an ‘economy car’ because of its 25mpg, then there’s an RT with a 370bhp 5.7-litre Hemi, and then, of course, there’s the one everyone really wants, the 6.1-litre SRT-8. As is the tradition at Chrysler, the RT also offers an optional Track Pak.

Chevy Volt will do 230mpg

GM are claiming 230 mpg for the Chevy Volt The premise is that the vast majority of buyers for the Chevy Volt will do no more than 40 miles a day. Which just happens to be the range that the Volt has. So I suppose they could have worked out the cost of the electricity to fully charge the Volt, converted that in to the cost of petrol and come to the conclusion that it does 230mpg.

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.
