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.

2015 Nissan Murano to hit the stage in NY

When the Nissan Murano launched in the early-2000s it was one of the first crossovers to eschew truck-like looks in favor of more sporty styling. For the third generation, Nissan is rumored to be taking the CUV's design even farther with inspiration from the wild Resonance concept that debuted at the 2013 Detroit Auto Show. According to Edmunds, Nissan will unveil the next-generation, 2015 Murano and an unnamed concept at the New York Auto Show in April.
The new Murano will go on sale this fall on the same front-wheel drive platform as the Altima, Pathfinder and next-gen Maxima. Its size will be roughly unchanged compared to the current model, and there won't be a seven-seater option. Nissan spokesman Dan Bedore told Edmunds that it already offers "three rows in the Rogue as an option and three rows in the Pathfinder for everything. We don't need another three-row crossover." There will also be a rumored hybrid version using the Pathfinder's supercharged 2.5-liter four-cylinder engine, a 22-horsepower electric motor and lithium-ion battery. To disappoint the dozen people who will miss it, the much-maligned Murano CrossCabriolet will not make it to the third generation. Let's all shed a tear.

This is what happens when you drive your Nissan Leaf beyond empty

If you see an AAA truck bringing someone a can of extra gas, it's rarely a big deal, but when an EV driver runs out of charge, people pay attention. Whether its a writer for The New York Times or hardcore Tesla fans, people are curious about this newfangled technology and the things that could go wrong. "I don't know what the opposite of range anxiety is. Range annoyance?" – Robert Llewellyn Well, few people have more fun with their EV than Robert Llewellyn, the actor (best known for Red Dwarf) and star of his own pro-EV show Fully Charged. And he's good at educating people on the EVs as well. In the latest episode, he tries something in his first-gen Leaf that he's never done before: drive until the battery is completely empty. When the car just keeps on going well beyond the official range estimate, Llewellyn gets frustrated. "I don't know what the opposite of range anxiety is," he says. "Range annoyance?" After 91 miles, he finally comes to a stop. Watch the video below. In the end, all Llewellyn needed to do to get up and running again was to get towed home and plug in. A few hours later, he was ready to go, this time with his range estimate at 93 miles. Compare that with the dangers to your gas engine if you run out of gas and you might wonder why so many people worry about an EVs range. This content is hosted by a third party.
