Chevy Volt sales surge with 2016 model, Nissan Leaf continues Autumn fall

The Nissan Leaf and Chevy Volt have been locked in sales combat since they arrived within a short distance of each other way back in 2010, and we continue to follow that fight closely. Though both vehicles approach driving efficiency from a different angle, they each have plugs and owners put a surprisingly similar number of electric miles on them. With the launch of its 2016 model, the Bowtie brand now appears to have the upper hand, clocking in a solidly improved performance for the month of October. According to GM's sales charts, the Chevy Volt made it into the loving embrace of 2,035 buyers last month. That's up a whopping 41 percent over the same period in 2014, and more than a 100 percent improvement from the 949-unit result in September. Now, we don't know how many of these were 2015 models and how many were the all-new 2016 edition. Dealers are, no doubt, incentivized to move the old inventory, and the latest and greatest is still only available in a limited number of states. Breaking out the sad trombones, Nissan recorded a mere 1,238 units moved in October. That's down 52.2 percent from the same month in 2014. That's also nine fewer examples than last month. Despite its recent sales travails, the Leaf still leads the calendar-year-to-date figures by a commanding 14,868 to 11,299 tally. We imagine the Japanese manufacturer is counting on an improvement in the situation once the 2016 model, with its larger, optional 30 kWh battery becomes available. You can compare these two stalwarts with the rest of the green-vehicle field in our By The Numbers post due out tomorrow. Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales volt

EcoCar3 will convert Camaro to bitchin' eco rides

In the 47-year-history of the Chevrolet Camaro, there have been countless college-age kids spending a ton of time getting under the hood and souping 'em up. Now, General Motors is adding a twist to the concept by donating 16 Camaros for the EcoCar challenge that puts university teams together to wring out better fuel-efficiency out of various vehicles. No word on whether there will be donuts on anyone's lawn, as suggested by 80's punks the Dead Milkmen, but the idea's never a bad one. EcoCar3 will feature 16 teams such as Arizona State, Penn State, Ontario's University of Waterloo and, of course, Detroit's Wayne State University. They'll spend the next four years "[reducing] environmental impact, while maintaining the muscle and performance expected from this iconic American car," as the EcoCar organizers say. The goal is to maintain body design and safety standards while boosting efficiency and lowering emissions, but the actual process is far more complicated than that description suggests. The California Air Resources Board (CARB) and Bosch are among the sponsors of the contest, which is also put on by the US Department of Energy and managed by Argonne National Laboratory. Penn State won Year Two of the three-year EcoCar 2 competition with its E85 plug-in hybrid electric vehicle converted out of a Chevy Malibu. The grand-prize winner of EcoCar2 will be announced in June. Check out the EcoCar3 website and see the announcement video below for more details. This content is hosted by a third party.

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.
