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 911 2.7 RS values up by nearly 700% in the last 10 years [w/video]

These days if you have a wad of cash to invest in a classic car, Ferrari seems to be the best option. Hagerty's price index for the Italian supercars was up 43 percent in 2014, and Prancing Horses made up eight of the highest-selling vehicles at auction for the year. However, if you really want to watch your funds grow faster than practically any other legal investment, it might be worth setting your sights north of Maranello to Porsche in Germany. According to research from the Discovery Channel, the 1973 Porsche 911 Carrera 2.7 RS is the quickest-appreciating vehicle in the past decade, at least in the UK. In 2004, prices hovered around 65,000 pounds ($101,350 in current money), but buying one today would set you back over 500,000 pounds ($779,600). Rarer lightweight models go for even more. More than just a solid investment, buyers get what is considered to be the ultimate expression of the early 911. Built as a homologation special for racing, Porsche used the classic tactic of fitting a larger engine to boost power to about 210 horsepower while simultaneously cutting weight. A lower front air dam, extended fenders for wider wheels and ducktail spoiler at the back made sure the grip, aero and styling fit the motorsports attitude. You can get a brief taste of what it's like to drive one of these rare Porsches in the video from The Telegraph below. This one is even for sale, with an ambitious price of around 600,000 pounds ($935,000), and it also features legendary racer Derek Bell's autograph on the ashtray. Hopefully the car's eventual buyer remembers that the RS is a fantastic piece to drive, too, and stretches its legs every once in a while.

Porsche's latest Driver's Selection keeps enthusiasts happy at home

Porsche fans - and there are certainly plenty of them out there, even in here on the Autoblog editorial staff - can be pretty emphatic about their enthusiasm, insisting that the 911 is the very definition of the sportscar. And for some, merely admiring one from afar or even leaving theirs parked outside isn't enough. For just such enthusiats, Porsche Design has expanded its Driver's Selection with some tantalizing additions for the home and office.
First up is a desk chair made from the bucket seat in a 911 Carrera, which we have to admit we'd rather be sitting in right now over this blasted, rather unexciting ergonomic office chair. It's covered in black leather (the same you'd find inside an actual 911) embossed with the Porsche emblem and features electronic backrest adjustment.
There's also a wall shelf made from the carbon-fiber rear spoiler a 911 GT3 Cup racecar that can support up to 264 pounds of downforce in the form of books, trinkets and whathaveyou. And there's a limited-edition resin model of the 918 Spyder in 1:8 scale. The items haven't hit the Porsche shop just yet, so we don't have pricing information, but if they tickle your fancy, the online store has plenty more to offer.
