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.

2015 Porsche Cayenne Turbo S gets faster, more powerful [w/video]

Porsche just isn't letting development of the Cayenne Turbo S cease. The 2014 edition was unveiled at last year's Detroit Auto Show boasting 550 horsepower from the brand's 4.8-liter twin-turbo V8, and it could hit 60 miles per hour in 4.3 seconds to a 175 mph top speed. Those seemed like very impressive specs for an SUV, but only a year later, the German brand has revealed an even more powerful take on its flagship trim in the model lineup. The 2015 Cayenne Turbo S now makes 562 horsepower and 590 pound-feet of torque from the same V8. The key to seeing such a significant boost in grunt so quickly is that the two turbos are now integral and are located directly in the exhaust manifolds. Porsche's eight-speed Tiptronic automatic gearbox still routes power to all four wheels. All of the tweaks let the SUV hit 60 miles per hour in 3.8 seconds and a 176 mph to speed. Stopping should come quite rapidly too thanks to 16.5-inch diameter ceramic brake discs up front with 10-piston calipers. Of course, the Cayenne needs to be able to put that added grunt to good use. Porsche claims that the model can lap the Nurburgring Nordschleife in 7:59.74. Comparatively, the 550-hp Land Rover Range Rover Sport SVR previously touted its SUV 'Ring lap record with a circuit in 8:14 in 2014. The Turbo S doesn't try hard to show off its added prowess, though. Up front, the bumper and undersides of the door mirrors are done in high-gloss black paint. Meanwhile, the roof spoiler and wheel arches are body color. The 21-inch wheels with black edges provide a little flash, and LED headlights are standard. The interior should be comfy too with black and creme leather and carbon fiber accents. The whole package rings up for $157,300, plus $995 destination and delivery, and US deliveries start in late April. Check it out in Porsche's video below. This content is hosted by a third party.

The new Cayenne Turbo S The top athlete among SUVs At the 2015 North American International Auto Show in Detroit, Porsche is also introducing the new Cayenne Turbo S – the top model of the sporty SUV model series. Its re-engineered 4.8-liter V8 biturbo engine now develops 570 hp (419 kW) and 800 Nm (590 ft lb) of torque. A chassis that is tuned for maximum driving dynamics and packs a wide range of control systems also makes the Cayenne Turbo S a genuine top athlete.

Ferrari 458 Speciale vs Porsche 911 GT3 shows what Chris Harris does best

After a brief trip behind a pay wall, British auto journalist Chris Harris is back posting videos for free online, and shorts like this one are the perfect example of why his return is so welcome. Showing up at the damp Anglesey Circuit on the Welsh coast with the Ferrari 458 Speciale and Porsche 911 GT3, Harris ostensibly aims to find the better model. However, the final result really succeeds in showcasing the fun to be had behind the wheels of both supercars, particularly when initiating huge slides around the track. As Harris presents it, the vehicles get through the circuit in somewhat different ways The Ferrari is brash and "feels alive," as he puts it as it screams around the track. Alternatively, the Porsche is a bit more restrained, while still being able to show some emotion. In the end, it comes down to trying to get a controlled lap around Anglesey from this duo, but it's pretty clear that the times don't tell the whole story. If you're in the mood to watch two of the world's premiere supercars wag their tails in the wet, then this video cannot be missed.
