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.

Chevy Crossvolt name kept alive in new trademark application

In April 2011 General Motors submitted a trademark application with the US Patent and Trademark Office for the word "Crossvolt." In November of this year, the application expired for lack of a statement of use. But in August of this year, GM applied again for the same trademark, leading some to believe that it intends to apply the name to a vehicle. That vehicle could explain the mule in sliced-and-diced Chevrolet Orlando bodywork caught in several spy shots this year, theorized to be some kind of Toyota Prius V or Ford C-Max Hybrid competitor; or it could be a production version of the Chevrolet Volt MP5 concept showed off at the Beijing Motor Show in 2010, which was about the same size as the Chevy Orlando. Or it could be none of those things – but the fact that Chevrolet is keeping it current makes us believe it will be... something.

2016 Chevy Volt auctioned off to help the robots

One of the cool things about the 2016 Chevrolet Volt extended-range plug-in being auctioned off to raise money for kids' science and robotics program is that even the sedan's color sounds very scientific. Indeed, it's fitting that a "Kinetic Blue" Volt will be used to advance the scientific education of the country's students, according to Hybrid Cars. That is, if it fetches enough cash. Chevrolet parent General Motors was kind enough to donate a 2016 Volt to the so-called FIRST K-12 robotics program (FIRST stands for For Inspiration and Recognition of Science and Technology). The program was founded in 1989. Last year, General Motors engineers worked with about 10,000 FIRST students in the US, but it looks like GM is now going the cold-hard-cash route to make its mark on future scientists. Bidding for the vehicle will take place until the morning of November 19, and, hopefully, it will generate enough interest to drive the bidding price up beyond its MSRP. As of Tuesday morning, nine bids had been taken, with the top one at $27,750. That's all fine and good except the car is pretty loaded with bells and whistles, and it's 53-mile electric-only range is a considerable jump from the first-generation Volt, so the car's "estimated value" is $40,245 (not factoring in the $7,500 federal tax incentive). That's a pretty good jump over the 2016 Volt's base price of $33,995, which marked a $175 price cut from the 2015 model. So pony up, folks. It's for the kids. Related Video:
