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.

2015 Porsche 911 GTS starts at $114,200*

Purists often criticize Porsche for creating products like the Cayenne, Panamera and recently launched Macan, saying they dilute the true sports car spirit of the brand. It's an argument we've heard before, and one we counter with two points. First: No they don't. And second: These are Porsche's volume superstars, and the money they rake in allows the company to create dozens of versions of its well-liked sports cars. Want proof? Have a look at the gallery above, where you'll see four new versions of the 911, all with GTS badges on their rumps. This means Porsche now offers 19 versions of the 911. Nineteen.
Porsche offered a GTS version of the 911 in its previous generation, and this new one seeks to slot somewhere between the standard car and the hardcore GT3. It's available in coupe and cabriolet forms, with either rear- or all-wheel drive, starting at $114,200, *not including $995 for destination. The GTS Cabriolet comes in at $126,100, while models equipped with AWD will set you back $120,900 or $132,800 for the coupe or convertible, respectively.
All GTS models get the 430-horsepower version of the Carrera S' 3.8-liter flat-six with the Powerkit, which also includes the Sport Chrono package and the sport exhaust. If equipped with the PDK dual-clutch transmission, the 911 GTS will hit 60 miles per hour in just 3.8 seconds (or four seconds flat, if you've got the Cabriolet) - one tenth of a second quicker than the normal Carrera S. The car's top speed varies, depending on trim or transmission, but Porsche says the car will hit anywhere from 187 to 190 mph, flat out.

Why you must buy an air-cooled Porsche 911 now

"Because" might be a good response to our headline, but as a vintage (purists might call 'proper') Porsche 911 is hardly cheap, we suspect you'll need a better explanation than that. Enter Drive editor Mike Spinelli.
Spinelli sits down with Zac Moseley and Mick Prichinello from Classic Car Club Manhattan to first explain why the market for old, air-cooled 911s has gotten so hot over the past few years, and to discuss if it's a bubble that's about to burst. Following that, this video is really is just three guys sitting around talking about old Porsches for 35 minutes. Which, you know, we're pretty onboard with.
