Audi outlasts rivals to win 13th Le Mans title

As is so often the case, the 2014 Le Mans was a war of attrition, and Audi managed to prevail once again after all 24 hours had been recorded in the history books, with its Audi R18 E-Tron Quattro claiming first and second places, followed by Toyota in third. Drivers Marcel Fassler, Andre Lotterer and Benoit Treluyer inherited the lead in their No. 2 Audi after the No. 7 Toyota, driven by pole-sitter Kazuki Nakajima, was forced to retire with electrical problems in the 15th hour.
The No. 2 Audi led the race until it was forced to the pits to replace a turbocharger in the 17th hour, allowing the No. 1 Audi, driven by Lucas di Grassi, Marc Gene (who was a last-minute replacement for Loic Duval, who crashed hard during practice) and defending champion Tom Kristensen, led the race until the 21st hour, when it too had to pit with turbocharger issues. This gave the No. 20 Porsche of Timo Bernhard, Brendon Hartley, and Mark Webber the lead until it was forced off the track with gearbox problems, eventually finishing in 38th position.
In LMP2, the Jota Sport Zytek Z11SN-Nissan driven by Simon Dolan, Harry Tincknell and Oliver Turvey claimed victory, the first five LMP2 finishers all powered by Nissan. Down a level in GTE-Pro, No. 51 AF Corse Ferrari 458 Italia GT2 driven by Gianmaria Bruni, Toni Vilander and Giancarlo Fisichella finished one lap ahead of the leading Corvette Racing C7.R. And finally, the No. 95 Aston Martin Racing Vantage GTE driven by Kristian Poulsen, David HeinemeierHansson and Nicki Thiim won the GTE-Am race two laps ahead of a Proton Porsche 911 GT3 RSR.

Aston Martin Valkyrie could beat that new Nurburgring record, Red Bull F1 boss says

During last weekend's Austrian Formula 1 Grand Prix, Race Fans asked Red Bull F1 team principal Christian Horner about the Aston Martin Valkyrie. The question was whether the coming hypercar, a collaboration between Red Bull and title sponsor Aston Martin, could beat the stunning lap record around the Nurburgring just set by the Porsche 919 Hybrid Evo. Horner's answer: "I'm not sure a Formula 1 car could actually do it, but I think that the Valkyrie — certainly the track version of the Valkyrie — could be a contender." That's a qualified endorsement, but it still counts as support merely putting the Valkyrie AMR Pro in the conversation. Let's compare, shall we? The 919 Hybrid Evo is based on the 2017 World Endurance Championship-winning 919 Hybrid. Freed from motorsport regulations, Porsche Motorsport upgraded numerous performance bits. The 2.0-liter, turbocharged V-four-cylinder went from 500 hp to 720 hp. The two KERS units went from 400 hp to 440 hp. We don't have a figure for downforce, but items like active aero, a larger front diffuser, optimized turning vanes, and larger rear wing increased downforce by 53 percent over the WEC car, at the same time being 66 percent more aero efficient. It weighs 849 kg dry, or 1,868 pounds because Porsche threw out everything that didn't contribute to speed. The Valkyrie specs we know of so far state a weight of 1,000 kilograms, or 2,200 pounds. Powering that is a custom, naturally aspirated, 6.5-liter AMR Cosworth V12 with more than 900 horsepower, augmented by a kinetic energy recovery system contributing around 230 hp. According to Autocar's sources, the Valkyrie could generate up to 4,000 pounds of downforce at an aerodynamically-limited 225 miles per hour. That boggling number comes courtesy of Adrian Newey's prowess at making changes such as openings between the front wheel arches and the cockpit that work the front wing harder. The two-seater coupe's unrestricted top speed is 254 mph. Note, though, that the Valkyrie AMR Pro will be more powerful, lighter, and could have even more downforce. And since Aston Martin and Newey continue to work on the hypercar, specs could get even better before deliveries begin. Right now, Horner's suggestion doesn't seem all that outrageous. We'll also wait to see if the Mercedes-AMG Project One pokes its nose in the ring, too. Not long ago, AMG chief Tobias Moers said it's "reasonable to speculate" the F1-inspired hypercar could claim an absolute lap record around the 'Ring.

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.
