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.

Chevrolet only automaker to win EPA's 2015 Climate Leadership Awards

Chevrolet was the only automaker to be on the list of entities for the US Environmental Protection Agency (EPA) Climate Leadership Awards. Of course, the accolades had nothing to do with any vehicle's tailpipe emissions, General Motors can still be proud. The automaker is engaging in what it calls the Chevrolet Clean Energy Campus Campaign. Chevy is working with the US Green Building Council, among other groups, to find ways for buildings in primary and secondary schools as well as college campuses to reduce their collective carbon footprint via better design. The EPA pointed out the "carbon performance methodologies" used by Chevrolet to run the program and spur lower emissions from its campus partners. The effort is part of Chevrolet's broader goal to reduce greenhouse-gas emissions by as many as 8 million metric tons of CO2. And it's going to take more than bunch of plug-in Volt and Spark EVs to do that. Other entities feted by the EPA include UPS, Bank of America, the cities of San Francisco and Oakland, Clorox and Tiffany & Co. Yes, Tiffany. Take a look at the EPA's press release below, and find out more information on Chevy's program here. UPS, Bank of America, SC Johnson Among 16 Organizations across the U.S. Recognized for Climate Action / EPA also recognizes Chevrolet Clean Energy Campus Campaign, San Diego Regional Climate Collaborative in new Innovative Partnerships Category WASHINGTON – From an innovative partnership enabling colleges to sell carbon credits to fund clean energy projects on campuses to some of the country's leading corporations setting and exceeding aggressive emission reduction goals, the U.S. Environmental Protection Agency's Climate Leadership Award winners announced today are demonstrating that innovative actions to combat climate change are smart business decisions. Sixteen organizations and one individual representing a wide array of industries from finance and manufacturing to retail and technology show exemplary corporate, organizational, and individual leadership in response to climate change. "I am proud to recognize our Climate Leadership Award winners for their actions to reduce the harmful carbon pollution that's fueling climate change," said EPA Administrator Gina McCarthy. "Our winners are demonstrating that a healthy environment and a strong economy go hand in hand.
