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.

Magnus Walker turbocharges his love for the Porsche 911

He's had his fill of early, long-hood Porsche 911s - he owns at least one from each model year, from 1964 to 1973 - so Magnus Walker, a fanatic of the Stuttgart, Germany-based automaker, recently set his sights on the early Porsche 930, as documented by this XCAR video called 'Turbo Fever.' Let us translate: pretty soon Walker will own all of the earliest, non-intercooled 911 Turbos - at least one from each model year, starting at 1975 and ending at 1977 (though the 1975 911 Turbo Carrera never officially was imported to the US by Porsche, so it'll be tougher to find one Stateside).
Any Porsche enthusiast can tell you why they love their car, and it often comes down to the small details that differentiate one model year from another. One of many examples is the mid-'80s 928. They look similar, but the basic difference between a 1984 Porsche 928 S and a 1985 928 S (US-spec) is two camshafts and 54 horsepower, though each car's V8 has its own pros and cons. We'll let Magnus Walker tell you all about the 930 and what makes the first three years special, as he's becoming quite the expert on early, air-cooled 911s. When the nearly 15-minute mini-documentary was filmed, which you can view below, he already had added four early 930s to his collection!

Porsche 911 already testing next refresh

The latest Porsche 911 may still be a newer car, but that hasn't stopped the German company from starting development of a facelifted version of the rear-engined sports car, testing in what looks like southern Europe.
Due to hit the market in 2015, our spies think what we're seeing here is the new GTS variant, which, following the evolution of the last-generation 911, will make its debut on the facelifted car. Featuring the wider rear haunches of the all-wheel-drive Carrera 4, the GTS should enjoy a slight power boost, to 408 ponies.
Aesthetically, there are some additional vents in the rear bodywork, along with a revised front bumper and tweaked day-time running lights. The taillights get some attention as well, and will likely grow over the current car's skinny rear lamps.
