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.

2016 Chevy Camaro leaked on CNBC

It seemed inevitable. Eventually some outlet would get access to fully uncovered pictures of the sixth-generation 2016 Chevrolet Camaro and let them loose early. Embargoes break. All. The. Time. And for this round, credit goes to CNBC's Squawk Box. The program, according to the GM Inside News forums, had been talking about the new Camaro "all morning," when it dropped a trio of images of the new muscle car. Consider this, then, our first full look at the 2016 Camaro, a car we detailed extensively earlier this morning. In general, the leaked images confirm much of what we discussed in that post regarding the car's looks – an evolved style, with a slim grille up front, a rounded tail, and a very short rear deck. Check out the leaked images, give our Camaro round-up a read, and strap in for tomorrow's big Camaro reveal.

Recharge Wrap-up: meet the Luka EV project, VisibleTesla allows Model S hacking

Select Registry is partnering with Tesla to install chargers at many of its lodgings. More than 170 hotels, inns and bed & breakfasts will install Tesla High Power Wall Connectors for their guests to use. So far, 63 properties have installed the chargers. Eventually, Select Registry members in 34 states as well as Nova Scotia will offer charging on-site. Tesla's wall charger provides the Model S with 58 miles of range per hour. The hotels will rent you a room for the full night, as well. Read more in the press release below. Tesla Model S owners can hack their car with the VisibleTesla app. The free, open source app allows users to check on and control the status of the car and its subsystems, similar to Tesla's official apps. VisibleTesla can also be used to schedule certain automated commands. For example, its creator, Joe Pasqua, has his car send him a text message reminding him to bring his bags with him when he enters the grocery store parking lot. Other users have the car remind them if the car is not charging at a certain time, or schedule the car to turn on the heat before departure.

Employees, particularly the utility's energy efficiency experts, will use the cars to travel to customers' homes and businesses to conduct energy audits. "We are leading by example and demonstrating to our customers, and other Georgia businesses, that electric transportation works for all drivers," says Georgia Power Chairman, President & CEO Paul Bowers. Georgia Power also offers charger rebates and special rates for EV customers. Read more at Domestic Fuel. The Luka EV is a project to build an affordable, lightweight, retro-looking, road-legal electric car in one year. The team wants to get the car certified for use on EU roads by September 2015. They have goals of achieving a driving range of 300 kilometers (about 186 miles), keeping the cost under ˆ20,000 (about $22,280 US at current rates) and the weight under 750 kilograms (about 1,650 pounds). The builders recently completed their first range test of the working vehicle, which uses in-hub motors for propulsion. Learn more at the Luka EV project page on Hackaday.
