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.

Ford GT dominates Le Mans qualifying, gets slapped with performance adjustment

Fifty years after Bruce McLaren and Chris Amon drove the Ford GT40 to victory at the 24 Hours of Le Mans, Ford is poised for a historic return to the Circuit de la Sarthe. The new Ford GT took the top two qualifying positions in the LMGTE Pro class, and four of the top five. Ferrari's 488 filled in the rest of the spots in the top seven, the first two from AF Corse. In other words, we're primed for a reboot of the classic Ford-Ferrari feud at this year's race. Or not, as the ACO, which organizes the 24 Hours of Le Mans, announced sweeping pre-race Balance of Performance (BOP) adjustments this morning that make this year's GT class anybody's race. In LMP1, last year's overall winner Porsche locked up the top two spots with the 919 Hybrid and will lead the entire field at race start. Toyota's two-car factory effort followed with qualifying times 1.004 and 2.170 seconds behind the pole lap. Audi rounds out the manufacturer-backed LMP1 class in fifth and sixth. Full qualifying results can be found here. The storyline for the GT cars is perfect - some say too perfect. Ford's class-leading times came after BOP adjustment to the Corvette Racing C7.R before qualifying. BOP is intended to level the playing field in the class by adjusting power, ballast, and fuel capacity. (Check out this explainer video for more, or even just if you love French accents.) But the process is riddled with unknowns and ripe for accusations of sandbagging. That is, if the Ford cars were intentionally slow in practice they could hope for BOP adjustment to improve their race chances. On the Corvette side, last year's GTE Pro winner went from the top of the field to the bottom, barely improving from practice to qualifying. If you think Le Mans is as rigged at the NBA Playoffs, well, it's not that simple. Because if Ford and Ferrari held back until qualifying - the eighth-place Porsche 911 RSR is three-and-a-half seconds off the class pole time - it was a pretty dumb strategy. This morning, the ACO tried to put things back in order by limiting the boost in the Ford GT's twin-turbo V6 and adding 11 pounds of ballast. Ferrari was also given extra weight but allowed more fuel capacity. The Corvette and Aston Martin teams were both given breaks on their air restrictors, which will allow their engines to make more power. Both Ford and Porsche also received extra fuel capacity.

2016 Porsche 911 GT3 RS prowls into Geneva with biggest NA engine in the 911 range [w/video]

We've been waiting for the debut of this road-going and race-ready Porsche 911 GT3 RS for quite some time now. As is typical for high-profile sports machines, the new 911 has been foreshadowed with spy shots and information leaks aplenty, all pointing to this grand day at Geneva. Here she is. Just a glance at the duct-sliced bodywork and massive rear wing will tell you that this Porsche means business, but let's look at its bona fides. The heart of the matter, under that short rear deck, is the largest-displacement and most powerful naturally aspirated engine in the 911 family, with 500 horsepower and 338 pound-feet of torque developed by the 4.0-liter flat-six. That hoss of an engine is mated to a newly developed version of Porsche's PDK dual-clutch gearbox – with functions such as "paddle neutral" that effectively works like depressing the clutch on a standard manual, and a Pit Speed button for on the track. Working in concert, engine and trans allow the GT3 RS to sprint to 60 miles per hour in 3.1 seconds, hit a quarter mile in 11.2, and lap the Nurburgring Nordschleife in just seven minutes, 20 seconds. (That 'Ring time makes it the fastest current 911 around the benchmark course, and five seconds faster than the current 911 GT3 – so quick.) Weight has been saved via exotic materials; the car sports a magnesium roof and carbon fiber for the trunk and engine lids. Overall the RS is 22 pounds lighter than the GT3, but also boasts a lower center of gravity. As we said at the top, there's a wide, low and aggressive body kit on the GT3 RS, all engineered with racing performance in mind. That huge rear wing is balanced in the front by a deep chin spoiler, and the front wheel arches have been punctuated with vents that help to increase downforce on the front axle. The roll cage is the most obvious interior modification to let one know that this is a racing tool, but Porsche has also slathered the space in Alcantara and installed carbon-fiber bucket seats (based on those found in the 918 Spyder) to drive the point home. The cost of such racing glory will be steep at $175,900 plus a $995 destination charge, but not out of the scope of the current ask for the 911 range, when you consider that a Turbo S runs over $180k. Look for 911 GT3 RS deliveries to start in July of this year in the US, and for track days to be more competitive for the addition.
