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 Targa 4 GTS caters to a very specific customer [w/video]

Porsche is happy to cater to some very specific buyer demographics, and the brand's newly unveiled 911 Targa 4 GTS at the 2015 Detroit Auto Show is the perfect example of that tendency. The sports coupe is aimed at the customer who wants open-air driving without a full convertible, all-wheel drive traction and a little extra performance, all wrapped in a sporty package. Launching in the US in late-April, 2015, for $132,800, plus a $995 destination charge, this high-performance Targa benefits from all of the goodies from Porsche's GTS line. That gives it a 3.8-liter flat-six boasting 424 horsepower and 325 pound-feet of twist, and the choice of either a seven-speed PDK or seven-speed manual. The model also gets the Sport Chrono package, PASM, 20-inch wheels and a sport exhaust. Picking the PDK means the Targa 4 GTS can hit a top speed of 188 miles per hour and sprint to 60 mph in 4.1 seconds. Opting for the manual makes the run to 60 take a few more ticks at 4.5 seconds and scarcely cuts the top speed to 187 mph. The Targa 4 GTS is more than just about boosted performance, and shows off some handsome styling tweaks, as well. It wears a modded front bumper with an extra opening to cool the middle radiator. Plus, the wheels are 20-inch units from the 911 Turbo S, and the Bi-Xenon headlights get smoked coverings. Inside, drivers are held firmly in place by Sport Plus seats covered partially in black Alcantara. Porsche apparently sees a hole in its lineup that a higher-performance Targa can fill, and here it is.

The new 911 Targa 4 GTS More powerful, dynamic and exquisitely styled To mark the 50th anniversary of the 911 Targa, Porsche is offering this very popular model in the more powerful and dynamic GTS version for the first time. The targa concept of the 911 Targa 4 GTS delivers very safe driving enjoyment with all-wheel drive and a rollover protection bar; it also delivers open-air fun with a targa top that stows fully automatically. Contributing to a boost in dynamic performance are the 430 hp (316 kW) GTS engine together with the standard Sport Chrono package, PASM chassis, 20-inch wheels and a sport exhaust system.
