The new Chrysler 300C goes on sale today, with prices from £35,995. It looks the same as the 300C launched in 2005, but this is a new model. From launch it will be diesel-only, which shows just how far petrol sales have faded for big saloons in the UK – even the Americans have noticed. The 3.0 litre engine provides 296 bhp and fuel economy of 39.8 mpg. CO2 emissions are a less-than-terrible 185 g/km, but that will be a problem for companies that only choose cars under the crucial 160 g/km tax break.
