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.

Trucks and tidbits from GM's earnings report

General Motors announced this morning that 2018 was a good year for it financially, thanks in large part to the company's performance in North America, which was predicated, according to the company, on "strong pricing, surging crossover sales, successful execution of the company's full-size truck launch, growth of GM Financial earnings, and disciplined cost control." GM reported full-year income of $8.1 billion and EBIT-adjusted income of $11.8 billion. Crossover sales in 2018 were 1,034,808, an increase of 7 percent compared to 2017 deliveries. Throw in the body-on-frame SUVs and the ute number is a total 1,295,700. But let's face it: It is the trucks that really matter. The Chevy Silverado and Colorado, the GMC Sierra and Canyon. Altogether, GM sold 973,463 pickups in the U.S. in 2018. Although Ford gets bragging rights for F-Series sales, GM gets to point out that it has a greater aggregate number. An important factor regarding the trucks and the reported income is that during the last quarter, more than 90 percent of the new 2019 trucks were crew cabs (which have a higher sticker), and at GMC more than 70 percent were Denali and AT4 models (which have even higher stickers). According to reporting by Bloomberg, GM's pickup trucks combine for $65 billion in annual revenue. Clearly when the 2018 sales of the Silverado — 585,581— dwarf the combined sales of both Buick (206,863) and Cadillac combined (154,702), pickups are what matter to the overall health of the company in a way that it is difficult to otherwise achieve. The "disciplined cost control" is something that is very much in the public eye right now, as the company is taking out thousands of its workers, and there is still the "unallocated" plant situation and other plants that will remain under capacity. The numbers in GM's earnings report probably made Unifor members' heads explode in consternation, coming fresh off their Super Bowl ad: " GM, you may have forgotten our generosity, but we'll never forget your greed." But there are a couple of curiosities in the full GM earnings release. One is that so far as its autonomous efforts go, it mentions only that (1) in the first quarter of 2018 Cruise introduced a production-ready autonomous vehicle, and (2) Cruise attracted $5 billion in external capital from SoftBank and Honda. Not a whole lot of love for autonomy. Good thing they have the trucks to fund the program, to say nothing of the external capital.

The story of the 2014 Chevrolet SS: "Luxury, power, refinement, handling"

Not including the women and men who built it, the 2014 Chevrolet SS has only been seen in person by a piddling number of people - fewer humans than would fill the gymnasium at a high school volleyball game. Not including the men and women who built it, no one has driven it. Even so, it is already saddled with two controversies: the way it looks and the way it shifts.
First to that shifting. Did we love the last Americanized Holden, the awesomely sportsome Pontiac G8 GXP, and its six-speed manual? Of course. Do we wish the SS came with a six-speed manual? Of course. But we'd like a toboggan to come with a manual transmission. We'd put a manual transmission on a weasel if we could because we're just wired that way; if it moves, it should come with a stick and a clutch. Or at least the option.
Let's climb down off the ledge, though. We haven't driven the SS and we have no idea how good (or not) the automatic is. And the Hobson's Choice in transmissions when it comes to sport sedans like the BMW M5, Mercedes-Benz E63 AMG and Jaguar XFR-S and, oh yeah, cars-that-really-should-have-manuals like the Audi R8 and Nissan GT-R and Porsche 918 and every single Lamborghini and Ferrari, for instance, hasn't stopped us from enjoying what is clearly the gruesome, dual-clutched demise of Western automotive civilization. Because in spite of our ululations at the dying of the six-speed light, we understand.
