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 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.

Experience Daytona in 27,894 photos

This "video" of the 24 Hours of Daytona is composed from tens of thousands of individual photographs that have been put together into an intriguing but jolty moving picture show. The project was shot at the 24 Hours of Daytona. It was commissioned by Porsche from photographers Camden Trasher and Zach Miller, who pieced it together from no less than 27,894 photographs they shot at the sports car racing season opener in Florida in January. Porsche has won the Daytona endurance race more than any other manufacturer, with 18 overall wins to its name – way ahead of second-place Riley whose Daytona prototypes have dominated the race in recent history with 10 wins from 2005 through 2015. This year an LMP2 prototype built by Ligier and powered by Honda won for the first time, with the Corvette team dominating the GT categories. Porsches came in third in GTLM and second in the GTD class. Related Video:
