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.

2017 Porsche 718 Boxster: Old name, modern performance

Porsche set the bar pretty high when it attached the number 718 to the new Boxster. The original Porsche 718 Spyder from the late '50s and early '60s remains one of the most iconic in the company's history. Nameplates aside, the biggest change to the new 718 Boxster can be found under the rear deck. That's where Zuffenhausen has embraced the latest trend in downsizing and turbocharging. In place of the previous naturally-aspirated flat-sixes, the new 718 packs a 2.0-liter turbo boxer four good for 300 horsepower, or a 2.5-liter version with 350 hp. They're smaller than the engines they replace, but also more powerful – and offer a significant improvement in torque as well. The result is a 0-60 time as low as 4.0 seconds – in what's long been considered the "junior" Porsche sports car. Of course Porsche didn't just swap the engines out and call it a day. The styling has been updated inside and out, and there's new equipment as well. The finished product will go on sale in April – but that's in Europe where it's been unveiled today at the Geneva Motor Show. It'll hit US dealers in June, and we can look forward to a 718 Cayman version with a fixed roof to follow soon as well. This content is hosted by a third party.

Hyundai, Porsche top J.D. Power APEAL study

Just as they did in the Initial Quality Study, Porsche and Hyundai have taken the premium and non-premium crown, respectively, for the 2014 J.D. Power APEAL study. This is the tenth consecutive year for that Porsche has been rated the best premium make in the APEAL study, which attempts to figure out how pleased owners are with their purchases. For 2014, it asked 86,000 owners of MY2014 cars to rate their vehicles in 77 different categories 90 days after their initial purchase. The resulting figures were plugged in deliver the APEAL score, which is rated on a 1,000-point scale.
The industry average sits at 794 points for 2014, although that's a one-percent decline over last year's rating. In this year's study, premium brands averaged 840 out of 1,000, while non-premium makes average 785. For their part, Porsche netted an impressive 882 points, while Hyundai earned an 804. Interestingly, only four non-premium brands (Hyundai, Ram, Volkswagen and Mini) finished above the industry average for 2014.
It's also interesting to see the clear delineation between premium and non-premium brands, with an eight-point gap between the non-premium champ, Hyundai, and the lowest-rated premium brand, Volvo.
