Mercedes G63 AMG: Details, photos & video

Fri, 20 Apr 2012 00:00:00 -0700

Mercedes G63 AMG Ahead of a debut at the Beijing Motor Show next week, we have the first photos and video of the Mercedes G63 AMG. Last week we reported that Mercedes are adding a pair of AMG models to the top of the new G Class range, with the V8 G63 AMG and the G65 AMG offering astonishing performance from a car that’s been around almost as long as Bruce Forsyth. Sadly the UK won’t be getting the G65 (although if you’re mad enough to spend £250k on a G Class you can bring a LHD one in from Germany), but we will be getting the G63 AMG with the 5.5 litre bi-turbo.

Redesigned Ford Focus expected to get 40 mpg highway

Tue, 19 Oct 2010 00:00:00 -0700

The redesigned 2012 Ford Focus will get an estimated 40 mpg in highway driving with an all-aluminum 2.0-liter engine mated to a six-speed, dual dry-clutch automatic transmission. The normally aspirated engine combines variable camshaft timing and high-pressure direct fuel injection to crank out 160 hp and 146 lb-ft of torque. That compares with 140 hp and 136 lb-ft from the aluminum 2.0-liter engine used in the current-generation Focus.
