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 to present Vision Gran Turismo concept at Goodwood?

Power up your PlayStation and pop in any edition of Gran Turismo and you'll have hundreds of cars to choose from. But arguably few have managed to bridge the gap between that virtual world and reality than Nissan.
The Japanese automaker is the one responsible for putting the best gamers behind the wheel of actual race cars with its GT Academy, co-sponsored by Nissan and Gran Turismo. Yet while the likes of Mercedes-Benz, BMW, Volkswagen and Mitsubishi have already revealed their Vision Gran Turismo concepts specifically designed for the game, Nissan has been left behind. And as it is apt to point out in its latest infographic, that's not a position to which it's accustomed.
The graphic outlines all 148 Nissan vehicles you can drive in Gran Turismo, but leaves the last one under wraps, identified only by the date June 10, 2014. That's this Tuesday, when Nissan is hotly anticipated (thanks in no small part to the Tweet below from Nissan VP Andy Palmer) to reveal its own Vision Gran Turismo concept at the Goodwood Festival of Speed.

2021 Toyota Camry AWD vs. midsize all-wheel-drive sedans | How they compare on paper

Just as crossovers have become the dominant body style in the car market, the all-wheel drive they frequently feature has become more popular. In fact, all-wheel drive is so popular that automakers are increasingly putting it in traditional cars. The latest car to add driven wheels is the 2021 Toyota Camry. It will offer all-wheel drive on most of its trim levels, though only with the four-cylinder engine. It isn't alone in this market, though. So we've compiled the Camry's specifications, along with those of a couple of its competitors for comparison. For the purposes of this analysis, we're sticking with the AWD veteran 2020 Subaru Legacy equipped with a naturally aspirated 2.5-liter engine and the relative newcomer 2020 Nissan Altima. Both are similar in pricing and power to Camry. We've skipped the turbocharged Legacy and the turbocharged Ford Fusion with all-wheel drive as both have higher base prices and significantly more power. We'll take a look at these three sedans engine output, fuel economy, pricing and space. Below is a chart with all the raw numbers, and below that is more in-depth discussion of the cars. Performance and Fuel Economy These sedans are very closely matched, but one area where a clear winner emerges is in output. The Camry has a solid 21 horsepower and roughly 10 pound-feet of torque over the Subaru and Nissan. This, despite all of the engines having the same displacement. That power should make it quicker than the approximately 50-pound-heavier Subaru, though the Nissan Altima may stay with it thanks to its curb weight being about 100 pounds less than the Toyota. Also worth noting is that only the Toyota offers a traditional automatic transmission, whereas the Subaru and Nissan rely on CVTs. Subaru and Nissan have both dramatically improved their CVTs to the point they're quite unobtrusive, but if you strongly prefer the feel of softly shifting gears, the Toyota is your choice. In our experience, all three of these sedans are pleasant to drive with suspension and handling clearly tuned in favor of comfort over quickness. Fuel economy is close to a dead heat. Toyota hasn't announced official fuel economy numbers for the all-wheel-drive model, but we can estimate that, as with most all-wheel-drive variants, mileage will be slightly lower than normal models. We're betting it will only about 1 mpg worse than front-drive variants. That puts it in the same 29 to 30 mpg overall range as the Subaru and Nissan.
