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.

Hot air balloons caught in high winds drag fullsize SUV

A sudden storm front whipped up enough wind to send some hot air balloons flying into the air in Wisconsin over the weekend. One ballon proved so energetic that it was able to drag a fullsize SUV across a field and into a stand of tents. The freak accident occurred at Balloonfest in Waterford, Wisconsin. Spectators were horrified as balloons dragged handlers to the ground and launched with terrified pilots clinging to their baskets. Organizers had started packing up the colorful balloons due to ominous storm clouds when the wind kicked up. "Happened just like that; it was crazy," Nathan Fricke, crew member, told Fox 6. Winds were clocked at 40 to 50 miles per hour. A balloon caught in the wind dragged a large SUV (we think a Suburban or Yukon XL) hundreds of feet and into a cluster of tents on the edge of the staging area where balloons were on display for festival goers. Considering that the SUV surely weighs well over 5,000 pounds, it's lucky that no one was injured in the incident. News Source: Fox6Now Weird Car News Chevrolet GM GMC SUV

Chevrolet FNR is a sharp vision of the future in Shanghai

The Shanghai Motor Show is about more than just displaying the latest extended-wheelbase luxury sedans to the Chinese populace. Chevrolet is taking advantage of the event to debut its vision of the future of motoring with the FNR concept, and the capsule looks like it could be fresh from off the set of Blade Runner. The FNR imagines what a fully autonomous, electric vehicle might look like many years from now and is meant to appeal to young, Chinese consumers. The concept's design from the minds at GM's Pan Asia Technical Automotive Center does a pretty neat magic trick, too. Most times it's a mass of glass and curving lines that looks very sci-fi, but then the dragonfly doors open upwards to reveal some knife-edged angles in the styling, as well. As a cutting-edge concept, this capsule is also packed with futuristic tech. Power comes from magnetic hubless electric motors in each wheel, and it could charge wirelessly. Crystal lasers generate the headlights and taillights, and radar in the roof would allow scanning the surroundings for autonomous driving. The interior is similarly imaginative as the rest of the styling. Passengers are enveloped in blue light while sitting in mostly mesh chairs with huge bolsters. Keys have been done away with entirely in favor of iris recognition. Once on the road, the front seats even swivel around to more easily talk with rear passengers. Check it all out in the gallery above for a glimpse a Chevy's vision of what might be next.

They were joined by the Bolt EV concept and the 2015 Captiva, which made their China debut. The new models were introduced as Shanghai GM celebrates the 10th Anniversary of its Chevrolet brand in China. They will appear alongside 12 other models on the Chevrolet display at Auto Shanghai 2015, this year's leading auto show in China, which starts tomorrow. Chevrolet-FNR The Chevrolet-FNR is an autonomous electric concept vehicle that offers a glimpse at mobility of the future. It was developed in Shanghai by GM's Pan Asia Technical Automotive Center (PATAC) joint venture. Engineering, design and electrification teams drew on their past experience developing electric concept vehicles.
