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.

$76,400 Porsche S E-Hybrid will debut in Paris

The 2015 Porsche Cayenne S E Hybrid will be an all-new model, one that adds a plug – and the required associated technological bits – to the currently available Cayenne S Hybrid. The most important of those bits is a 10.8-kWh lithium-ion battery, but Porsche's Calvin Kim told AutoblogGreen that the SUV's electric-only range is still pending certification, but Hybrid Cars says that Porsche is estimating it'll be somewhere between 11 and 22 miles, "depending on the style of driving and route topography." Other than the new battery, the electric motor has been upgraded to a 95 horsepower/70 kW unit (up from the 47-hp/34 kW motor in the Cayenne hybrid without a plug). The overall powertrain now puts out a total of 416 hp and can go from 0 to 60 miles per hour in 5.4 seconds. Alongside the electric parts, there's a 3.0-liter supercharged V6 engine and an 8-speed automatic transmission. You can find all of the E-Hybrid's available specs here and stay tuned for more information on the new plug-in SUV when it makes its debut at the Paris Motor Show in early October. The SUV will go on sale in the US on November 1, 2014 with a starting MSRP of $76,400, plus a destination charge of $995. In a new press release (available below), Porsche is also proudly saying, once again, that it will be the world's only automaker offering three plug-in hybrid models, once the Cayenne S E-Hybrid hits the market. The others are the Panamera S E-Hybrid and the 918 Spyder. How long will this reign at the top last? World premiere of the Porsche Cayenne S E-Hybrid in Paris Leading the industry: Porsche offers three plug-in hybrid models Stuttgart/Atlanta. The new Porsche Cayenne S E-Hybrid celebrates its world premiere at the Paris Motor Show. It is the world's first luxury SUV to offer a plug-in hybrid drive, setting new standards in its segment. The Cayenne S E-Hybrid also makes Porsche the leading manufacturer of plug-in hybrid vehicles: Complementing the Panamera S E-Hybrid and the 918 Spyder, Porsche is the only manufacturer worldwide to offer three plug-in hybrids. In addition to the Cayenne S E-Hybrid, Porsche is presenting the other models that comprise the new generation of Cayenne including the Cayenne S, Cayenne Turbo, and Cayenne Diesel. Increased efficiency and performance, even more precise handling, a sharper design and a broadened array of standard equipment are its defining features.

Porsche turns up boost on 911 range with new Turbo and Turbo S

You didn't honestly think Porsche would stop with just a turbocharged Carrera and Carrera S, did you? No, that'd be silly. Of course Stuttgart had to follow up those two smash hits with a new Turbo and Turbo S. Naturally, both cars build on the 370-horsepower Carrera and 420-horsepower C2S. The base Turbo offers 540 horsepower and starts at $160,195, while the Turbo S packs 580 horsepower and demands an extra $28,900. Adding a folding fabric top to either model will drive the cost of entry up by $12,300, regardless of output. For those keeping track at home, that's a 20-horsepower bump for both vehicles over the previous models, while the Turbo's price jumps by $8,100 and the Turbo S will cost an extra $5,400. In terms of actual performance, the Turbo hits 60 in just 2.9 seconds and will carry on to 198 miles per hour, a one-tenth and three-mph improvement over the current car. Going for the Turbo S will only shave a tenth of second off the 60-mph sprint, although you'll pick up an extra seven mph on the top end. That compares favorably to the current car, which takes 2.9 seconds to get to the magic six-oh and stops accelerating at just 197. The stopwatch improvements are only part of the story. Porsche claims the new dynamic boost function will maintain turbo pressure during sudden throttle load changes, like you might experience when pushing the 3.8-liter, twin-turbocharged flat-six hard. That means snappier throttle response. As with the current 911 Turbo and Turbo S, Porsche's excellent dual-clutch transmission is the only way to fly. This content is hosted by a third party.

Both cars also get Porsche's Sport Chrono Package and Porsche Active Suspension Management as standard, while upgrading to the Turbo S will add Porsche Dynamic Chassis Control and carbon-ceramic brakes. While there's lots of free hardware, we're betting Porsche's options catalog will remain just as robust. As for the design, you can expect the same look shown on the new, turbocharged 911 Carrera, albeit with some Turbo and Turbo S exclusives. 20-inch wheels are standard, with super-wide rubber in the back – Porsche doesn't list tire specs, but the rear hoops are 11.5-inches wide. Both the 911 Turbo and Turbo S will get their big debut at the 2016 Detroit Auto Show. Naturally, we'll have much more then, including live photos from the show. In the meantime, read on for the official press release from Porsche.
