Porsche 911 Reimagined by Singer First Drive [w/video]

"There's still a couple hundred rpm left," coaxes the voice from the passenger seat. Though I'm wailing down a mercilessly knotted up Southern California canyon road in someone else's half-million dollar coupe, my manic pace apparently isn't sufficient for the Singer Vehicle Design rep in the right seat. On one hand, my Irish co-pilot with more than a passing resemblance to Bruce Willis is playfully ribbing me because I've been driving hard, but haven't yet hit the 4.0-liter engine's 7,200-rpm rev limiter. On the other hand, if you've never heard of an Irish bloke who doesn't drink because he's got control issues – well, now you have, because the dude's stocky paws are white knuckling the car's rain gutter like his life depends on it. Within my microcosm of itinerant auto writing some days are odder than others; this particular Monday is beginning to look like one of the weirder ones. Rolling, In My Four-Point-Oh The car in question, according to a release I've signed prior to the drive, is a "Porsche 911," a "Porsche," or a "911," but certainly not a "Singer Porsche," a "Singer 911," or any number of variants thereafter. Sigh. I suppose "Porsche 911 reimagined by Singer Vehicle Design" will suffice? Oh, legal department. Nomenclature aside, what started life as a 1990 Porsche 911 has been dismantled and rebodied with a carbon fiber skin that makes it more closely resemble a small-bumpered, wide-hipped 1960s-era 911 than it does its melted bumper donor car. According to company founder (and former Catherine Wheel vocalist) Rob Dickinson, the decision to source a 964-series 911 was based on its delicate foothold between the model's combination of heritage and drivability. "I think the 964 is in the sweet spot of having one foot in old school 911 thinking with the [semi-trailing] rear suspension, which honors every earlier 911, while having a front end which is very much of the modern era and allows the car not to feel like an antique," he tells Autoblog. The specimen I'm driving is the latest evolution of Singer's vision of the reinterpreted 911, distinguished by a 4.0-liter powerplant that's been heavily modified by Ed Pink Racing (and, in Singer tradition, the serial number matches the donor car's chassis). The Van Nuys, California-based firm knows a thing or two about high-strung Porsche mills: the tuner has a long history of rebuilding such mechanical exotica such as 917, 935, and 962 race engines.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

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.
