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 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.

What car should James Robertson buy to drive his famous 21-mile commute?

The Internet has been abuzz this week with the story of Detroit resident James Robertson, the 56-year-old factory worker who has walked some 21 miles to work for the last 10 years. The Detroit Free Press brought Robertson's story to the fore, helping an online fundraising campaign to generate more than $275,000 (as of this writing). The original goal was just $5,000, or about enough to replace the used Honda that died on Robertson back in 2005, and left him walking. So, newly flush with funds, what's the perfect car for Robertson to buy? Let's look at the specifics of his situation, and try to pick out the best options. Here's what we know: Robertson's commute is (famously) 21 miles; he lives in downtown Detroit (for now) and seems pretty humble, so something very flashy is probably out; former Honda aside, his ties to the city (and statements about being a Ford fan) seem to indicate a Detroit Three company product is best; he's a single guy with a girlfriend; he's got to deal with Michigan weather, and the sometimes fickle snow removal processes in The D. Here are some choices: Ford F-150 Robertson is on record as being a Taurus fan, and after a decade of walking I've no doubt that the big sedan would offer a cozy respite. Still, as a car guy and a student of the industry, I'd have a hard time recommending a sedan so clearly in need of replacement. Especially when The Blue Oval has such great stuff within the rest of its roster. The 2015 F-150 seems almost perfect for Robertson. Opting for either of the new EcoBoost V6 engines should help keep fuel bills in reasonable check, while healthy ride height and four-wheel drive will get him to work on time even during the snowiest of snow days. Better still, with a fat options sheet and car-like ride quality, Robertson can have just about every amenity he might want, in a package that won't disrespect his blue-collar roots. Chevrolet Colorado You guys saw this one coming, right? The smaller footprint of the midsize Chevy pickup, relative to some of the other options here, should be an advantage for urban parking and driving. And again, 4x4 is an option for the nasty weather, the running costs should stay pretty low and there aren't many tech/luxury features that can't be had in-cabin. I'd go ahead and splash out on the Crew Cab bodystyle, too, just in case Robertson feels like starting a carpool.
