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 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.

Porsche rolls out new Macan GTS with 360 horsepower [w/video]

Porsche is expanding both its Macan line and its range of GTS models with the launch of the new Macan GTS. The new performance model slots in between the Macan S and Macan Turbo, packing a mightier punch, upgraded equipment, and sportier styling. The enhancements naturally start under the hood, where the Macan GTS packs a 3.0-liter twin-turbo V6 good for 360 horsepower and 369 pound-feet of torque. That's 20 more horses than the Macan S but 40 less than the Turbo, driving all four wheels through a seven-speed dual-clutch transmission. The result is a 0-60 time quoted at 5.0 seconds (or 4.8 with the optional Sport Chrono pack) and a top speed of 159 miles per hour. You know, just to stick it to the other German cars that limit themselves to "only" 155. Of course, Porsche didn't just tinker with the engine and leave it at that. Compared to the Macan S, the GTS features a retuned air suspension, recalibrated electronics, ride height lowered by 10 millimeters, and 20-inch wheels with a matte black finish. The interior also benefits from specific sport seats with Alcantara trim, and the new Porsche Communication Management system. There's a new exhaust system and upgraded brakes, as well. The Macan GTS is just the latest such model to join the range, alongside GTS versions of the Boxster, Cayman, 911, Panamera, and Cayenne. While sales of the new Macan GTS start today in its home market, US customers will have to wait until March to place their orders. MSRP is listed at $67,200 (plus destination), pretty evenly splitting the difference between the existing S and Turbo models. This content is hosted by a third party.
