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 Classic launching branded motor oil for air-cooled boxer engines

It's hard not to love the look of a classic Porsche. Whether it's the upside-down bathtub styling of the 356 or the gradual evolution of the 911, there is a little beauty in all of them. However, the older they get, the more that needs repaired to keep them on the road. Porsche Classic is helping out, though, by introducing its own brand of motor oil for the demands of the company's vintage, air-cooled engines.
Developed at the Porsche Development Centre in Weissach, Germany, Porsche Classic Motoroil comes in two weights - 20W-50 for the 356, 914 and 911 models up to the 2.7-liter G-Model and 10W-60 for 3.0-liters-and-up engines through the 993-chassis 911. The company claims that the air-cooled engines have different heat demands than traditional, water-cooled units, and this oil is made to meet those requirements.
According to Porsche, modern, synthetic oils are sometimes too effective when it comes to old engines. They are fantastic at sopping up debris, but those deposits are often holding archaic seals together. Suddenly removing them can cause leaks. The new oil is specifically designed to work with the old-fashioned materials found in its classics. The company also knows that most owners aren't driving their vintage cars everyday. So this formulation is more alkaline that normal to neutralize acids that they build up and corrode components.

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. Porsche and Hyundai weren't the only automakers to take home recognition. Dodge managed to tie Porsche for the most segment awards, with three. The Challenger, Charger and Dart all topped their market. There were a number of two-segment winners, as well, with Audi, Ford, Mercedes-Benz and Nissan capturing a pair of segments each. Scroll down for the full press release from JD Power on this year's winners. Automakers Struggle to Impress Owners with Increased Usefulness of In-Vehicle Technologies And Features on All-New and Redesigned Models Dodge and Porsche Each Receive Three Segment-Level Awards; Audi, Ford, Mercedes-Benz and Nissan Each Receive Two WESTLAKE VILLAGE, Calif.: 23 July 2014 - Although manufacturers are putting more and more technologies and functionality in their new and redesigned models, satisfaction with these features is not significantly higher among owners of those models than among owners of carryover models, according to the J.D. Power 2014 U.S. Automotive Performance, Execution and Layout (APEAL) StudySM released today. The APEAL Study, now in its 19th year, serves as the industry benchmark for new-vehicle appeal. Owners evaluate their vehicle across 77 attributes, which combine into an overall APEAL score that is measured on a 1,000-point scale.
