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.

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.

Porsche 911 going all-turbo this year save for GT3 and GT3 RS

The coming Porsche 911 GT3 RS will represent another high-water mark for the brand, and another milestone. Its 500-or-so horsepower and extreme aero are predicted to lop more than five seconds off the 7:20 Nurburgring lap time of the current GT3, making it "comfortably less" than 7:20. Beyond that, its naturally-aspirated 3.8-liter will form the basis of the turbocharged engines going into the standard range of 911s later this year as 2016 models. That's right – if you're looking for a sub-GT3 911 that gulps its air without compressed assistance, then you've only got a few months to get a new one into your garage. Emissions regulations are the reason, of course, with Porsche's R&D chief Wolfgang Hatz saying that, "Every new model will have lower CO2 than before," and "if you look at euro per g/km, then it's turbo." We don't know what the engine lineup will look like, however; a few months ago Car reported that the base 911 would get a smaller-displacement version of the engine, while the S would stick with 3.8-liter displacement and jump to 520 horsepower, which is the same as the current Turbo. After that, Hatz said, "at the end of the decade electrification has to be the next huge step." That means a hybrid 911 is being cooked up somewhere. Yet even as the brand leaps into the new, there's a chance it could dip a toe back into the old: the 911 GT3 RS will launch with a PDK, but Hatz's team is considering adding the option of a seven-speed manual. Elsewhere in the range, the Cayman GT4 is being engineered by Porsche Motorsport as an entry-level racer, with more power than the current Cayman GTS to go with some serious weight loss. They are also developing a track-only model for privateers. The standard Boxster and Cayman will get turbocharged flat-four engines, but there'll be a sporty Boxster that also loses weight and gets more power than the 325-hp Boxster GTS. And that mid-level supercar that's been floating in the ether for years and supposedly sent to purgatory again just last November? It's on the way by 2020 "at the latest," and will use a version of the new V8 that will eventually go into the Cayenne and Panamera.
