Porsche drops factory FIA GTE Pro racing program for 2016

Porsche has a wide-ranging motorsports program in store for next season, but it won't defend its title in the GTE Pro class of the FIA World Endurance Championship. This according to the road-map it laid out over the weekend at its Night of Champions year-end gala in Weissach. The German automaker enjoyed a massively successful racing season this year. With the 919 Hybrid, it took top honors for both drivers and manufacturers, winning the 24 Hours of Le Mans outright along with five additional races on the eight-round calendar to take both the drivers' and manufacturers' titles. With the 911 RSR, it also won the World Endurance Cup for GT Drivers and for Manufacturers, locking out the bragging rights in the GTE Pro category. Rather than return to defend its two GTE Pro titles, Porsche's GT racing department is essentially taking the year off. Reigning champion Richard Lietz and teammate Michael Christensen will have the opportunity to defend his title, but instead of a GTE Pro ride, they will drive for the Proton Dempsey team in the GTE Am category. They'll be joined at Le Mans by Wolf Henzler and at select points by Patrick Dempsey. That'll still put them in contention for the World Endurance Cup for GT Drivers, but without a works entry from the factory, Porsche will be out of the running for the GT manufacturers' title. The reason behind the rearrangement of its WEC GT program, according to Autosport, is to allow Porsche to focus on development of the next generation of sports racers. It's been the better part of three years since Porsche introduced the current 911 RSR, and though its performance in this year's championship clearly shows that it remains competitive, the thorough trouncing it received at Le Mans from the likes of the Corvette C7.R, Ferrari 458 Italia GT2, and Aston Martin V8 Vantage GTE show that it's not invincible. The all-new model is expected to be based on the latest generation of turbocharged 911s, to replace the current RSR. Over on this side of the Atlantic, Porsche still intends to defend its title in the GT class of the IMSA SportsCar Championship, where the Porsche North America team will field two 911 RSRs. One will be driven by defending champion Patrick Pilet and reigning Le Mans winner Nick Tandy (joined in the longer races by former McLaren factory driver Kevin Estre).

Magnus Walker pops up again, this time with his Irish Green 911

He was the subject of a short film called Urban Outlaw. He has been on Jay Leno's Garage. Twice. He even graced the cover of Road & Track in June. And after all of that, he appeared in a video by Hong Kong-based Silly Thing. So it isn't really surprising that Magnus Walker is at the center of attention in the latest video from XCAR, but it's surprising - and a treat - to see his mostly original Irish Green 1966 Porsche 911.
Powered by an air-cooled 2.0-liter flat six with 130 horsepower (more like 120 hp today, Walker says), riding on 5.5-inch wide wheels and turned with a wooden steering wheel, the little green 911 does represent some of the best aspects of classic car motoring.
Head on below to watch the long-form video on Walker and his Porsche, but if your time is limited, you're not missing much if you call it quits at five minutes - especially if you've seen his aforementioned videos before.

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.
