Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

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's baby Panamera delayed until 2019 or later

If you're enticed by the idea of a Porsche sedan but find the Panamera to be too big, your hopes may have been raised by the development of the so-called Pajun. But don't get those hopes up too much, because the latest word coming in from the Old World has it that the Panamera Junior has been delayed.
The Pajun was (and theoretically still is, despite tardiness) a project to apply to the Panamera the same winning formula that Porsche used to transmute the Cayenne into the smaller Macan. Its size would be closer to the BMW 5 Series and Mercedes E-Class than the larger Panamera, and employ an array of six-cylinder engines.
The smaller five-door was set to be the cornerstone of Porsche Product Strategy 2018, a plan that included several new models to be launched within the next four years. However, reports now indicate that the Volkswagen Group is counting on Porsche to help bolster its profits and is not keen on investing in new products at this time, pushing the Pajun and other projects back until 2019 at the earliest. Although much of the strategy remains undisclosed, it is believed to include (or have included) a sub-Boxster sports car and a supercar to slot in between the 911 and the 918 Spyder. There was also talk of a shooting brake version of the Panamera based on the Sport Turismo concept pictured above. What will become of those projects, however, remains to be seen.
