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.

Porsche says turbo'd 911 engines will still be revvy

Porsche fans really, really don't like change. Remember when the 911 moved away from air-cooled engines? Now, as the company prepares to move the vast majority of the 911 line away from naturally aspirated powerplants, one of the brand's highest ranking officials is speaking out to prevent a similar outcry. Dr. Heinz-Jakob Neusser, the head of powertrain development for the Volkswagen Group and a board member of the VW brand, told Car that turbocharging won't take away from the rev-happy nature of Porsche's current engines. "Turbocharging is possible with higher revs – it's not true to say that turbocharged engines must stop at 6000rpm," Neusser told Car at the 2015 New York Auto Show. "That's not true... If you look at McLaren, they already have in production turbo engines with high revs." With turbocharged engines, Nuesser explains, there's no need to go for a super high redline, because engineers are trying to spread the torque over the entire rev range. "It makes no sense to go to 10,000 rpm with a turbocharged engine," Neusser told Car. The other big concern that comes with the switch to turbocharging focuses on the 911's iconic flat-six exhaust note. Maintaining the car's well-known acoustic character shouldn't be an issue, Neusser said. "Noise is not a problem," adding that the Volkswagen Group knows a thing or two about building sweet-sounding turbos. "Look at the 911 Turbo; it has an extremely expressive noise today – that is not a problem. At the other end of the scale, the Golf R has it too," Neusser told Car. "You won't miss character with turbos, I promise." According to Car, the new turbocharged engines will arrive later this year at the 2015 Frankfurt Motor Show, as part of the current 911's facelift.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
