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.

Nissan withdraws from two races to focus on Le Mans

Nissan is making a huge bet and putting all of its chips on the 24 Hours of Le Mans for the race debut of the GT-R LM Nismo. The team will now skip the World Endurance Championship test at Paul Ricard in France later this month and also won't compete at the first two races of the season at Silverstone and Spa-Francorchamps. The team made the announcement through two tweets (embedded below). "Our main aim for this year was always Le Mans and we have decided to re-focus on that race," Darren Cox, Nissan Motorsport boss, said to Autosport. In the meantime, the company will keep testing the car in the US right up until the big race. The driver lineup and a GT-R Nismo for display will make an appearance at the season-opening round at Silverstone on April 12, though, according to Autosport. This isn't the first setback for the team. The GT-R LM suffered a failure of a "very minor" part during testing in early March at Sebring, and the team didn't have a spare with it. The car had run 68 laps over the preceding two days. The GT-R LM uses a powertrain unlike any other vehicle in its class. A twin-turbocharged V6 has front-mid-engine placement, and it's combined with electric motors making over 700 horsepower. In total, the system generates a claimed output of over 1,250 horsepower. With no competitive racing under its belt before Le Mans, the Nissan is definitely going to be a car to watch in the big event this year. This content is hosted by a third party.

Carlos Ghosn says his family played no role in escape from Japan

Men guard a vehicle as it arrives at the home where former Nissan Chairman Carlos Ghosn is staying in Beirut, Lebanon, Thursday. / AP   BEIRUT — The family of former Nissan boss Carlos Ghosn played no role in his escape from Japan, Ghosn said in a statement on Thursday, days after his abrupt arrival in Beirut from Tokyo, where he faces trial for alleged financial misconduct. "There has been speculation in the media that my wife Carole, and other members of my family played a role in my departure from Japan. All such speculation is inaccurate and false," said the statement. "I alone arranged for my departure. My family had no role whatsoever." Sources close to Ghosn said he was prompted to flee after a recent court session in which he learned that the second of two trials would be delayed until April 2021. "They [prosecutors] said they needed another whole year to prepare for it. ... He was distressed about not being able to see or speak to his wife," one of the sources close to Ghosn said. A request to see or speak to his wife over Christmas was also denied, the sources added, part of strict conditions set on his bail. The sources said Ghosn had grown distressed that authorities were pressuring his family to draw a confession from him after his daughter and son were questioned by Japanese prosecutors in the United States in early December.
