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.

2016 Porsche 911 GT3 RS prowls into Geneva with biggest NA engine in the 911 range [w/video]

We've been waiting for the debut of this road-going and race-ready Porsche 911 GT3 RS for quite some time now. As is typical for high-profile sports machines, the new 911 has been foreshadowed with spy shots and information leaks aplenty, all pointing to this grand day at Geneva. Here she is. Just a glance at the duct-sliced bodywork and massive rear wing will tell you that this Porsche means business, but let's look at its bona fides. The heart of the matter, under that short rear deck, is the largest-displacement and most powerful naturally aspirated engine in the 911 family, with 500 horsepower and 338 pound-feet of torque developed by the 4.0-liter flat-six. That hoss of an engine is mated to a newly developed version of Porsche's PDK dual-clutch gearbox – with functions such as "paddle neutral" that effectively works like depressing the clutch on a standard manual, and a Pit Speed button for on the track. Working in concert, engine and trans allow the GT3 RS to sprint to 60 miles per hour in 3.1 seconds, hit a quarter mile in 11.2, and lap the Nurburgring Nordschleife in just seven minutes, 20 seconds. (That 'Ring time makes it the fastest current 911 around the benchmark course, and five seconds faster than the current 911 GT3 – so quick.) Weight has been saved via exotic materials; the car sports a magnesium roof and carbon fiber for the trunk and engine lids. Overall the RS is 22 pounds lighter than the GT3, but also boasts a lower center of gravity. As we said at the top, there's a wide, low and aggressive body kit on the GT3 RS, all engineered with racing performance in mind. That huge rear wing is balanced in the front by a deep chin spoiler, and the front wheel arches have been punctuated with vents that help to increase downforce on the front axle. The roll cage is the most obvious interior modification to let one know that this is a racing tool, but Porsche has also slathered the space in Alcantara and installed carbon-fiber bucket seats (based on those found in the 918 Spyder) to drive the point home. The cost of such racing glory will be steep at $175,900 plus a $995 destination charge, but not out of the scope of the current ask for the 911 range, when you consider that a Turbo S runs over $180k. Look for 911 GT3 RS deliveries to start in July of this year in the US, and for track days to be more competitive for the addition.

Porsche 911 GT2 RS vs. Mercedes SLS AMG Black in battle of who can shred more rubber

We might be looking at the end of an era in European performance models. Mercedes-Benz is doing away with the SLS in favor of a rumored smaller and cheaper SLC, and Porsche has said that a new 911 GT2 isn't necessarily a sure thing, which means another 911 GT2 RS is even farther away. In its latest video, Evo's Jethro Bovingdon pits the ultimate versions of these German sports coupes against each other and finds two of the fastest cars the magazine has ever lapped around its track.
In one corner, there is the Mercedes SLS AMG Black Series that sits as the pinnacle of the company's halo model. It relies on the classic setup of a V8 mounted in front powering the rear wheels. On the other side, there is the 911 GT2 RS with a turbocharged flat-six mounted at the back, spinning the rear wheels. It was conceived to be Porsche's ultimate expression of a turbocharged 911, and while it's a few years old, Bovingdon shows that it's up to the task of racing a more modern rival.
Both of these rear-wheel-drive monsters are more than capable of some fantastically smoky power-slides, but they also show how great the last generation of sports cars was. Scroll down to check out the video.
