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.

Nissan could upgrade current GT-R yet again

Heisenberg himself would have been impressed by the unpredictability of the next-generation Nissan GT-R. We're pretty sure one is coming, we think it will be sometime around 2018, it could have a hybrid powertrain with an evolution of the 3.0-liter, twin-turbo V6 used in the GT-R LM Nismo endurance racer, and there's a chance its looks will point in the direction of the Nissan Concept 2010 Vision Gran Turismo concept. Oh, and rumor is that no matter what comes next, Nissan-Renault CEO Carlos Ghosn wants to sell more of them every month; GT-R sales are up about 40 units through August compared to last year, but that's still just 891 examples. What's Nissan going to do with the current GT-R for the next three years? According to a chat Top Gear had with Phillipe Klein, the company's head of product planning, Nissan can do more with the R35. Klein said, "We are very serious about this vehicle and its future," and, "There is still development potential there, always." That could mean any number of things, since we never have any idea what Nissan is going to do or not do with the GT-R. If Klein is talking about engineering more performance from this package and it's 3.8-liter, twin-turbo V6, does that mean a notable increase in horsepower for the standard version, or does that mean a super-duper edition hotter and faster around the 'Ring than the 600-hp, $149,990 GT-R Nismo? Or is it something else – because, frankly, the GT-R has plenty of performance right now and it's not the coupe's stat-sheet numbers that are holding it back. Since 2018 isn't that far away, we should probably know soon. Related Video:

Trucks, SUVs — and Camry — shine in mixed U.S. January vehicle sales

DETROIT — Automakers posted mixed U.S. new vehicle sales data for January, with American consumers continuing to abandon passenger cars for the larger pickup trucks, SUVs and crossover models that manufacturers also love because they are far more profitable. Total industry auto sales for the month rose 1 percent versus January 2016. According to Autodata Corp, which tracks industry sales, the seasonally adjusted annualized rate (SAAR) of U.S. car and light truck sales in January fell to 17.12 million units from 17.44 million a year earlier. Analysts polled by Reuters had expected a January SAAR of 17.2 million units. U.S. auto industry sales fell 2 percent in 2017 to 17.23 million vehicles after hitting a record high in 2016 and are expected to drop further in 2018 despite a solid economy. Interest rates are rising and around 4 million late-model used cars will return to dealer lots this year to compete with more expensive new ones. Automakers have used consumer discounts to boost sales, a growing concern for observers who say this undermines resale values and profits. Discounts declined in January, but remained above 10 percent of manufacturers' recommended prices. ""I think the industry has accepted that (sales) volumes will fall somewhat in 2018 ... and I don't think the industry is going to go over the cliff with insane incentives," Mike Jackson, chief executive officer of AutoNation Inc, told Reuters after his company, the largest U.S. auto retail chain, posted a higher quarterly net profit. Mark Wakefield, head of the North American automotive practice for consultancy AlixPartners, had a gloomier perspective. The industry's less-than-stellar sales performance for January showed "we are now past the peak," he said. "Automakers are now selling the deal instead of the vehicle," he said. "That's a tough spot to be in because that treadmill is hard to get off once you're on it." General Motors January sales rose 1.3 percent, driven by a 16 percent rise in fleet sales. Sales to consumers fell 2.4 percent. GM posted strong gains for models such as the Silverado pickup truck and Equinox crossover model, while its passenger cars continued to struggle. Ford The Blue Oval posted a 6.6 percent sales decline for January, with retail sales down 4.3 percent. Sales of Ford's F-Series pickup trucks - America's best-selling vehicle brand for decades — rose 1.6 percent. Passenger cars were down more than 23 percent.
