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 dealer: 2016 Leaf will have 110-mile battery option

Leave it to a local dealer in Indiana to spill the beans about the beans about the changes to the upcoming 2016 Nissan Leaf. Maybe. There's a dealer near Indianapolis called Andy Mohr Avon Nissan near Indianapolis and its website says that the new Leaf will come with two battery packs. The dealer says that the 2016 Leaf will come with two different battery trim levels. You can choose a car with the same pack as the 2015 Leaf has (and, thus, still get 84 miles of official range) or you can opt for the higher trim level, which will give you, "as much as 25 percent increased capacity, delivering a driving range of as much as 110 miles." Now, let's take all of this with some grains of salt and combine it with previous rumors. First, this does not seem to be any sort of information about a second-gen Leaf. We've heard plenty of rumors that the 2016 Leaf will have a 30-kWh battery pack that can go over 100 miles, but this is sort of a version 1.5 Leaf, since this longer range will be available in an updated current model and not yet the next-gen model. Nissan's Paige Presley, from Nissan's EV and technology communications, said simply that she, "can't comment on future products." We spoke with Joe Kline, the internet manager at Andy Mohr Avon Nissan, and he said that it was likely that the information about the two battery packs came directly from Nissan but he wasn't 100 percent sure. Kline said that the Andy Morh Avon Nissan dealership probably sold around 10 Leafs in the past year, mostly because the infrastructure isn't as built out as it could be in central Indiana. "They're not quite up to par with the charging stations around here," he said. With the longer-range version, the dealership's website says, "the new Leaf can find a home in even more garages."

Nissan releases official Maxima images following Super Bowl ad [w/video]

Following up on an all-too-brief glimpse during its 2015 Super Bowl ad, Nissan has released a pair of official images giving us a closer look at its heavily redesigned 2016 Maxima. The full-size sedan will make its official debut at the 2015 New York Auto Show, and it will do so wearing sheet metal that's been heavily influenced by the latest Murano crossover. A floating roof, aggressive beltline and swooping rear end all contribute to a dramatically different sedan than the one being replaced. It's a big car, this, but it appears very muscular from the angles that we have. You can check out the images Nissan has released up top, and if you happened to miss the car's appearance in the company's With Dad Super Bowl ad, we've embedded it below. Have a look.
