Porsche 918 Spyder gets tiny recall for rear control arms

As the recent US recall of a single Koenigsegg Agera shows, even low-production supercars aren't immune from safety campaigns. Now, there's another example that even the fastest cars can have their faults. The Porsche 918 Spyder is a pretty fantastic vehicle for its ability to mix hybrid fuel economy and incredible amounts of power, but Porsche has a problem on a few units of its halo model.
According to the recall document from the National Highway Traffic Safety Administration, Porsche needs to inspect and possibly repair five 918s in the US because the rear axle control arms may break, which could cause a loss of control while driving. In the full defect notice, Porsche says that it first noticed the problem on June 26 when the parts failed during "heavy duty durability testing (extreme race conditions)" at the Nardo test track in Italy. It transported the components back to the company's lab for inspection, and on July 18 it issued a stop-sale to inspect the suspension parts on the supercar. The automaker also contacted owners by phone to warn them not to use the car on track, until repaired.
The affected 918s will be inspected, and if the cars have the bad parts, the control arms are will be replaced. Obviously, this will be done at no cost to owners. According to a Porsche spokesperson speaking to Autoblog, in addition to the five US cars potentially affected, there were 45 worldwide. All of the cars have now been checked.

VW internal investigation finds 'no evidence' against suspended engineers

Volkswagen is still working out the chain of events that led to emissions-evading software being installed in 11 million diesel vehicles worldwide and deciding who was responsible for the treachery. So far, the German automotive giant's internal investigation hasn't publicly named many suspects, and three suspended executive-level engineers have been found not to be culpable in the wrongdoing, according to an anonymous insider speaking to Reuters. VW knows that the software began being installed in the EA 189 engine in 2008. The internal investigation has found that the emissions-evading tech was created because the powerplant was found to fail US standards. Plus, the diesel mill wasn't meeting cost targets, according to Reuters. The automaker responded by suspending over 10 employees, but three top engineers among them might not have been involved. Those put on leave include Heinz-Jakob Neusser from VW, Ulrich Hackenberg from Audi, and Wolfgang Hatz who led Porsche's research and group-wide engine development. The internal detective work hasn't turned up any evidence against these three men. In addition to VW's own inquires, government investigators in both the US and Germany are taking a serious look into the company's actions, too. So far, the automaker is setting aside about $7.3 billion to pay to fix the vehicles with the evasive software. Depending on what authorities find, the costs could grow quickly. Beyond the financial implications, the scandal has led to a serious shakeup in VW's corporate structure. Related Video:

Mercedes-AMG GT S pit against Porsche 911 Turbo in Evo Deadly Rivals test

When Mercedes-Benz announced that its all-new AMG GT would start at $129,900 deeply undercutting the $200,000-plus of its predecessor, the SLS AMG, immediate questions focused on how it'd stack up against the latest crop of high performers that occupy the mid-$100,000 range. Evo, over in the UK, didn't have to wait all that long. The latest installment in the outlet's "Deadly Rivals" series compares the AMG GT with the latest Porsche 911 Turbo. On paper, the test is sure to be interesting. The Mercedes uses a 4.0-liter, twin-turbocharged V8 with 503 horsepower and 479 pound-feet of torque, while a seven-speed AMG Speedshift dual-clutch shuffles power to the back axle. The 911 Turbo's formula is more of a known quantity – 520 hp from a twin-turbo, 3.8-liter flat six with the company's own PDK working in unison with all-wheel drive, torque vectoring and rear-axle steering. Of course, we're not going to spoil the results for you. Take a look at the video up top, and let us know what you think of Evo's latest track battle.
