Another cool projection vid, this time with a Porsche 911

Porsche has become the latest automaker to take advantage of clever projection technology. The automaker worked up a quick presentation for the 2013 911 Carrera 4S to show off a bit of "motionless driving." The display tracks the sports car from production to back-road caning and city-center cruising, displaying a variety of exterior color choices and wheel options without resorting to a two-dimensional video.
This isn't the first time we've seen an automaker use its new product as a projection screen. Subaru, Hyundai, Lamborghini and others have all done the same, and the trick never fails to be visually interesting.
As you may recall, we got to play with the 2013 911 Carrera 4S back in November and found the machine to be a better daily driver than its rear-wheel drive counterpart. You can check out the projection video below.

Watch the Chevy Corvette dismiss its Euro rivals at the hands of a Brit magazine

European auto writers, especially the British, have a bit of a reputation for favoring their own domestic cars over foreign rivals in comparison tests. Just think about how many times you've heard Jeremy Clarkson deify the latest product of UK loins while denigrating an American rival as a hopeless "Yank Tank." However, we have to tip our hats to the folks at Autocar because in its latest video comparing the 2014 Corvette Stingray to the Porsche 911, Jaguar F-Type V8 S and Audi R8, it's actually given the Vette a fair shake.
Autocar has put the Stingray through a battery of tests against what it considers to be the three best sports cars on sale in Europe today. And while the tests that it has chosen are somewhat random and subjective, it has concluded that the C7 can stand up against its rivals, even irrespective of its price. It's one thing to hear about how great the Stingray is from American writers, but it's great to know that not all Brits think we've gone crazy for calling the new Chevrolet "exquisite."

Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.
