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.

Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...

Evatran, Bosch will sell wireless home charger for as low as $1,998*

At the Consumer Electronics Show in Las Vegas today, the big news for plug in vehicles is that they can now start to ditch the plug. As expected, the system costs around $3,000 and is available for both the Nissan Leaf and the Chevrolet Volt. For the first 250 customers, though, Evatran is offering $1,000 off the standard price, a 30 percent discount. Deliveries start next month and Evatran says it expects the discounted units to all be snatched up in the first half of the year. The wireless charger charges as quickly as conventional corded systems. Called the Plugless Wireless EV charger, the 240-volt station will be installed by Bosch and needs a specific adapter to be used with the Volt or the Leaf (the Leaf version costs $100 more). So, any two-EV families out there will need to pony up double if there's a Chevy and a Nissan in the garage. Of course, since the Plugless system only works with older Leafs (2010-2012 model years - but with any Volt), any late adopters will not be able to take advantage of the new technology, for now. Evatran says the wireless charger "charges the Volt and Leaf as quickly as conventional corded systems and all vehicle features, such as charge-timers and phone applications, can be used seamlessly with the Plugless system." After the first 250 units, standard prices for the wireless chargers take effect again: $2,998 (Volt) and $3,098 (Leaf). Evatran says it will announce wireless chargers for additional vehicles and model years later this year. Evatran and Bosch offer Promotional Pricing as low as $1,998 to first 250 PLUGLESS™ Wireless EV Charging Customers LAS VEGAS, Jan. 6, 2014 /PRNewswire/ -- Evatran Group, Inc. ("Evatran"), in partnership with Bosch Automotive Service Solutions, announced today at the 2014 Consumer Electronics Show that it is offering reduced promotional pricing to the first 250 customers who opt to Go PLUGLESS with their electric vehicle ("EV") experience. The PLUGLESS system offers a convenient, wireless charging alternative to the repetitive process of unplugging and plugging-in electric vehicles. The reduced pricing includes all charging hardware and is as much as a 30% discount off the system's standard MSRP. The discount is available only to the first 250 customers. Initial shipments of the PLUGLESS system, the first wireless EV charging product in the world available to individual EV drivers, will begin in February 2014.
