Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.

NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.
