Nissan considering 200-mile Leaf to take on Chevy Bolt?

With 30,200 units sold, the Nissan Leaf posted its best year ever in the US in 2014. However, Nissan needs to keep looking over its shoulder because the Chevrolet Bolt Concept from the 2015 Detroit Auto Show clearly has success EV in its sights. Chevy claims that for roughly the same price (after incentives) as a Leaf, the future Bolt could offer a 200-mile range. Although, evidence continues to mount that the Japanese brand is hard at work on its next-gen electric hatchback capable of significantly longer driving distances. According to TheDetroitBureau.com, the next Leaf will reportedly debut in about two years and will be offered in a high-output version with 200 miles or more of range. It will all be possible thanks to new lithium-ion batteries with lower weight and higher power density. If accurate, the changes would more than double the model's current EPA-estimated 84-mile range and put the hatchback on sale at roughly the same time as the Bolt's debut, if it happens. "We want to be competitive," said Nissan CEO Carlos Ghosn to TheDetroitBureau.com during the Detroit Auto Show. "It may have even more range." In another speech, he also predicted that the company's EVs would become even more affordable. The statements are hardly a surprise from the company boss. Ghosn is a big proponent of electric power over other zero-emissions alternatives because it is cheaper overall, among other reasons. The latest speculation about battery innovations from the next Leaf actually echoes earlier leaks about the car. Ghosn suggested during a Japanese TV interview that the range could double for the new generation, and an unnamed engineer believed that 250 miles of driving was at least possible.

Infiniti puts EV plans on hold again

Think of it as the green-automotive industry's version of Groundhog Day. Nissan's Infiniti division is putting plans for its first mass-production electric vehicle on hold. Again. The Infiniti LE, whose concept version was unveiled 2012's New York Auto Show, is again being put up on the proverbial blocks, USA Today says, citing a presentation by Infiniti executive Michael Bartsch at a recent company event in Detroit. Essentially, the Nissan division has bigger fish to fry, in the form of boosting overall Infiniti sales, and doesn't yet want to put the effort into introducing the Infiniti LE. The Infiniti EV plans were first postponed by then-Infiniti President Johan de Nysschen during the summer of 2013, as de Nysschen wasn't quite buying into Nissan boss Carlos Ghosn's ambitious electric vehicle sales projections. De Nysschen resigned last summer to join General Motors' Cadillac division. One issue may be the fact that the Infiniti wouldn't be all that different from the Nissan Leaf. Despite the fact that US sales of that EV surged 34 percent last year compared to 2013, to 30,200 vehicles, an Infiniti version was apparently not enough of a selling point within the company. While the Infiniti is sportier looking than the Leaf and would boast inductive, wireless charging, it would have a similar power output and single-charge range as the Leaf.

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.
