Jaguar XFR Speed Pack

Jaguar has revealed a Speed Pack for the XFR, raising the top speed to 174mph and adding cosmetic tweaks. We have been expecting Jaguar to arrive at the Paris Motor Show next month with an XFR-S, an XFR with the same power boost as the XKR-S to offer an XFR that can hold its own against the new M5. That may still be happening, but perhaps Jaguar are only planning on giving us a low-fat upgrade to the XFR in the form of the XFR Speed Pack, revealed at the Moscow Motor Show?

MPG or performance: It's a trade with turbos

Some automakers say turbochargers offer high fuel economy and quick acceleration, the best of both worlds. Well, yes and no. Turbocharged vehicles allow automakers to keep power output high while they downsize engines for better fuel economy.

GM recalls ATS, XTS and Impala for brake lamp fix

Cadillac's 2013 ATS and 2013 XTS and the 2014 Chevrolet Impala are being recalled by General Motors because of a potential problem with the brake lamps. The National Highway Traffic Safety Association reports that the brake lamps may "intermittently flash without the brakes being applied, and the cruise control may disengage." The report states this could cause a crash if the following driver isn't warned to adjust vehicle speed. The recall impacts 1,627 copies of the sedans, and comes just two months after the new Chevy Impalas began rolling off production lines.
