Porsche 918 Spyder could lap the 'Ring even quicker [w/video]

Porsche had a lot to crow about at the Frankfurt Motor Show last week. Not only did it debut the new 50 Years edition and Turbo versions of the 911 and the new hybrid and diesel versions of the Panamera, but while unveiling the final production version of the new 918 Spyder, it revealed the record lap it set around the Nürburgring.
The 918 Spyder's 6:57 lap time makes it the fastest street-legal production car ever to lap the Nordschleife and the first to break the seven-minute barrier. But the driver who clocked the time thinks it can go even faster.
That driver was Marc Lieb, who has won the Nürburgring 24-hour race four times, making him something of an expert on the subject. In speaking with Australia's Drive TV, Lieb suggested that they could get even more out of the car, as you can hear for yourself in the video below.

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.

Porsche planning customer driving center at Le Mans

Porsche seems to be on a campaign to build driving centers for its customers to allow them to experience the capabilities of their cars on track. It has one under way in Los Angeles, another in development at its North American headquarters in Atlanta, and a British center set up at the Silverstone circuit. Now the latest reports indicate that Porsche is planning yet another driving center at Le Mans.
The new facility is earmarked to be built at the Circuit de la Sarthe right by the start/finish line, incorporating the Porsche Curves that bridge the Arnage corner and the Ford Chicanes on the West side of the famous track.
Porsche is reportedly still seeking approval from the Automobile Club de l'Ouest that manages the circuit, and once given the green light, would still take some time to complete. But the idea of driving a 911 flat out on the legendary track is likely to make more than a few mouths water, particularly as the German automaker prepares its full-on assault of the famous endurance race next year.
