Jaguar X-type refreshed for 2007

By Tim Pollard First Official Pictures 12 October 2007 09:03 Jaguar X-type for 2008: the lowdown Jaguar has finally given the X-type a facelift, but the 500 changes try their hardest to escape your attention.

Fiat unveils new 900cc TwinAir two-cylinder engine

Fiats of old used to feature noisy two-cylinders with a fetish for overheating, yet the Italians are at it again, this week releasing details of their new TwinAir two-cylinder 900cc engines.

But now we go back to the future with the return of a 5.5 litre V8 – admittedly a completely new engine (M571) – which this time round sports a pair of turbochargers and delivers 554 hp and 590lbs/ft of torque.
