Is Carbon Motors calling it quits?

For years, Carbon Motors Corp. has been teasing us -- and the nation's law-enforcement agencies -- with renderings and photos of its purpose-built E7 police cruiser. Drivers may not have to worry about seeing the E7's aggressive lines in their rearview mirrors any longer.

Porsche Panamera GTS arrives at LA Show

Porsche Panamera GTS Now that we’re a couple of years in from the launch of the Porsche Panamera, Porsche think it’s about time we got to know the hard-edge side of the Panamera, so the LA Auto Show has seen the arrival of the Porsche Panamera GTS. Just like other GTS Porsches – particularly the Cayenne GTS – it’s probably best to think of the GTS as a Turbo without a Turbo and a bit of attitude thrown in to the mix.# Despite its harder-edged stance and sporting pretensions the 2012 Panamera GTS is atill a bit of a lump, coming in at 1920kg thanks, in part, to the standard 4WD setup. But even with the lard and drive to all four wheels, the 425bhp V8 can still pick up its skirts and hustle to 62mph in a very respectable 4.5 secondsa and on to a top speed of 179mph.

Jaguar XK leaves the lineup

Production of the Jaguar XK stretched from 1996 with the XK8 and will wrap up as the final 50 limited edition XK models roll off the assembly line this summer. The farewell XKs will be branded as "Final Fifty Limited Edition" cars, and will carry the same specification as the current XKR model, along with some added features that celebrate the history of Jaguar and the evolution of the brand's grand touring coupes and convertibles. Under the hood, a supercharged 510-hp 5.0-liter V8 is capable of bringing the XK to 60 mph in 4.6 seconds according to Jag, and an active exhaust system helps ensure the engine note remains prominent.
