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.

Here are all the cars GM is axing as part of its restructuring

GM plans to kill off a couple of great and a few meh cars as part of its restructuring. Here's a rundown of all the cars being phased out of production. None of the vehicles GM axed were SUVs or crossovers. Instead, it was an action reminiscent of what Ford recently decided to do by discontinuing U.S. sales every Blue Oval sedan. GM just didn't explicitly say, "We're killing our cars," like Ford did — probably a smart move by GM. Keep scrolling down to see the full list of deceased GM models. Chevrolet Volt This one was the most surprising of all the cars GM decided to can, primarily because cars with plugs are supposed to be our future. However, maybe consumer demand just isn't quite there yet for a plug-in like the Volt. We came up with all sorts of ideas for what was to blame for the untimely demise of the Volt, so go check that out for a full breakdown of the situation. Cadillac CT6 Here's another car we'll be sad to see go. Cadillac's flagship sedan was such a joy to drive, and it served as the conduit to deliver GM's semi-autonomous Super Cruise system, which still hasn't been surpassed by any other company's technology in our books, even Tesla's Autopilot. That being said, GM does plan to produce the CT6 until March, with the last cars coming off the line set to be twin-turbo V8 V-Series models. If it's going to go, this seems like a pretty great way to make an exit. We'll be patiently awaiting the next flagship Cadillac once this one finally fades away. Chevrolet Impala The Impala is actually a pretty good car. It doesn't sell terribly, and we think it's a completely satisfactory car to drive. However, people would rather have a Traverse or Equinox these days, making the Impala one of the vehicles to find itself on this list. Chevrolet is keeping its smaller brother, the Malibu, but a big, full-size sedan just isn't what people are ordering up these days. It's unfortunate to see it go, but we won't be broken up over it. Chevrolet Cruze We wouldn't rank the Cruze at the top of the compact car class, but if you were looking for a small, cheap American car, it was either this or the Focus. The Cruze had the potential to be a true small performance car if Chevy had ever wanted to make it into one. But sadly, we're seeing it bow out before Chevy ever tried to slot a hot engine and suspension in there to make it competitive with other hot hatches. A Cruze SS would have made enthusiasts take notice.

Let's Drive NYC is GM's car sharing program for the Big Apple

Under a new car sharing program offered by General Motors and others, a New York Minute will cost about 15 cents. GM is working with a luxury-apartment building owner and a parking lot operator to run a car sharing program in Midtown Manhattan. The program is called Let's Drive NYC and it was announced Thursday. Let's Drive NYC is being offered to residents of the Ritz Plaza, a 479-unit luxury apartment building near New York's Times Square. The program is being run with the help of Icon Parking Systems, which runs about 200 parking garages in Manhattan where the cars can be parked. GM is contributing eight Chevrolet Trax crossovers and two Chevrolet Equinox SUVs, and the automaker is slated to add more vehicles "later." Residents of the Ritz Plaza, which is owned by Stonehenge Partners, can make "periodic apartment lease payments" and in exchange receive electronic credits for three hours of driving a month. After those three hours are up, the drivers will be charged less than $10 an hour, or as much as $75 a day. The program was piloted earlier this year to some of the apartment's tenants. The program marks the second bit of car sharing news in New York within the past two months. In August, Mercedes-Benz and Smart parent Daimler announced that its Car2go car sharing service would expand into Queens and add about 100 Smart ForTwo two-seaters to the city's program. Car2go made its New York debut in Brooklyn last October and has attracted more than 27,000 members since then. You can take a look at Let's Drive NYC's press release below. GM Unveils 'Let's Drive NYC' Car-Sharing Program NEW YORK, Oct. 1, 2015 /PRNewswire/ -- Running an errand to a big box store or planning a weekend excursion are about to get easier for some Manhattan residents because of a car-sharing program revealed today by General Motors. It's the company's latest move to deliver urban mobility options to customers around the globe. Let's Drive NYC is available to eligible residents of The Ritz Plaza, a 479-unit luxury apartment building at Times Square in midtown Manhattan, owned and managed by Stonehenge Partners. Residents use a GM-developed mobile app to reserve a vehicle and access parking in one of 200 garages throughout Manhattan managed by Icon Parking Systems. The fleet currently includes eight Chevrolet Trax small SUVs and two Chevrolet Equinox compact SUVs, with more vehicles to be added later.
