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.

Porsche Boxster and Cayman 4-cyl rated from 240 hp to 370 hp

Car magazine has information on the revised 981.2-series Porsche Boxster and Cayman twins that will inaugurate the all-turbo era for those two ranges. Almost all-turbo, that is - we're told that variants like the Cayman GT4 will continue with the flat-six. The rest, though, will come with a 2.0-liter, horizontally opposed, four-cylinder aided by just one turbocharger, according to Car's sources. Entry-level models will start at 240 horsepower, the S models graduate to 300 hp, the GTS trims get 370 hp. If accurate, the new new outputs will make for a wider power range than at present, and the base and S cars will go down in horsepower. Right now the Boxster gets 265 hp, the Boxster S gets 315 hp, and the Cayman lineup has ten more horsepower than the Boxster across the range but Car doesn't mention that continuing. The only gains come with the GTS models: the Boxster S will go up by 40 hp, the Cayman by 30 hp. To keep turbo lag from being an issue, Porsche could install some sort of e-boost to work while the turbo spools up "as a short-to-mid-term option." It is also possible that the Cayman will be sold as the entry-level vehicle in some markets at a lower price than the Boxster. The swap is planned to help Cayman sales, which have lagged the Boxster since launch. A 2016 unveil is predicted, perhaps at the Detroit Auto Show or Geneva Motor Show. Related Video:

Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.
