Chevy will reveal the Bolt EV tomorrow at CES

The moment that electric vehicle consumers and green propulsion enthusiasts have been waiting for is almost upon us, as Chevy confirmed that it will unveil the production version of the 2017 Bolt EV Wednesday at CES in Las Vegas. Chevrolet previewed the Bolt in concept form at the Detroit Auto Show almost a year ago, proposing a compelling rival to the likes of the Nissan Leaf and BMW i3. We've expected the CES debut for awhile, and Chevy projects that the finished product will boast a range of more than 200 miles on a single charge. That's nearly double the Leaf's range, and significantly farther than the i3 will travel even with the Range Extender kicking in. All of that for under $30,000 after federal tax credits. Of course, Chevy's own Spark EV costs much less, but will only go 82 miles before it needs to plug in again. If you won't be in Vegas for the unveiling tomorrow, you can catch it on Facebook. It will be the first vehicle to debut on the new Facebook Live, featuring both a live video stream and a 360-degree interactive interior video. Once out on the market, the Bolt EV will join the Spark EV, Volt PHEV, and Malibu hybrid in a growing array of electrified vehicles from the American automaker, rivaling the likes of Toyota and Nissan for the most electrified vehicles in its lineup. Chevrolet Bolt EV Will Debut at CES 2016-01-05 DETROIT – Chevrolet will unveil the 2017 Bolt EV at the International Consumer Electronics Show (CES) in Las Vegas on Wednesday, Jan. 6, and be the first auto brand to work with Facebook to debut a vehicle using Facebook Live. With the addition of the Bolt EV to a lineup that includes the all-new 2016 Volt, 2016 Malibu Hybrid and Spark EV, Chevrolet will offer consumers more affordable, electrified vehicle options than any other major automotive brand – solidifying its position as the leader in electrification. "The Bolt EV truly embodies the ingenuity that is at the core of everything we do at Chevrolet," said Alan Batey, president of General Motors North America and head of Global Chevrolet. "The technologies and the engineering expertise behind the Bolt EV are tremendous examples of the kind of innovation we intend to offer our customers, across an array of products at a tremendous value – something only Chevrolet can deliver." Building on the electrification expertise established by the Volt, the Bolt EV is a game-changing, long-range electric vehicle.

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.
