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 918 Spyder with Weissach package does 0-62 mph in 2.6 seconds

Porsche marketers are having a field day with the 918 Spyder after some last-minute tuning improved the car's performance. They now say that it's so fast it's already beaten itself. Let us explain: Using a Weissach package-equipped 918 as an example (which reduces the plug-in hybrid supercar's weight through the deletion of some interior items, more generous use of carbon fiber and magnesium wheels), the car's previous official 0-62 miles-per-hour time of 2.8 seconds has been cut to 2.6. Additionally, 0-124 mph takes 7.2 seconds and 0-186 mph is dispatched in 19.9 seconds, times that were reduced by half a second and 2.1 seconds, respectively.
In all-electric mode, a non-Weissach pack 918 does 0-62 mph in 6.2 seconds (with the package, 6.1 seconds), down from 6.9 seconds. Efficiency is also improved thanks to the final tuning. The New European Driving Cycle (NEDC) rating of a Weissach pack-equipped car equates to 94 miles per gallon, up three mpg compared to before. That's pretty good for a car with 887 horsepower!

Janis Joplin's psychedelic Porsche nets $1.76M at auction

Even though she famously asked the Lord for a Mercedes-Benz, Janis Joplin loved her 1964 Porsche 356C Cabriolet with its psychedelic mural called History of the Universe. The mind-bending droptop went for an amazing $1.76 million at a recent RM Sotheby's auction in New York City and shattered the original estimate of between $400,000 and $600,000 for the sale. Seven bidders in a fight over the trippy car helped push up the price, and this is now the most ever paid for a 356 at public auction. According to RM Sotheby's listing, Joplin bought the Porsche used in 1968 and quickly gave it to a roadie for her band Big Brother and the Holding Company to create the mural. He covered the entire exterior with a variety of motifs including a landscape across the passenger side, butterfly on the driver's door, a rainbow connecting two faces at the back, and an eye on the front. Joplin proudly drove the convertible regularly until her death at just 27 years old in 1970. After the singer's passing, Joplin's siblings eventually took control of the groovy Porsche but made the odd choice to repaint the car in the original Dolphin Gray. They eventually realized that was an awful idea, and two artists used photos to recreate the mural. The family then loaned the 356 to the Rock and Roll Hall of Fame in Cleveland, OH, in 1995, and this auction was the first time the convertible went up for sale since Joplin bought it. You can get a great look at all the psychedelic details in the gallery above. PSYCHEDELIC JANIS JOPLIN PORSCHE SHATTERS ESTIMATE, BRINGS RECORD $1.76 MILLION IN NEW YORK CITY NEW YORK (December 10, 2015) - Tonight at the RM Sotheby's 'Driven By Disruption' auction in New York City, The Janis Joplin 1964 Porsche 356 C 1600 SC Cabriolet sold for $1,760,000*, well over the pre-sale estimate of $400/600,000. Spurring a spirited bidding contest between collectors in the room and on the phones, seven bidders competed for the iconic daily driver of legendary rocker Janis Joplin. The outstanding sales price represents a new record for any Porsche 356 sold at public auction. Purchased by the Queen of Rock'n'Roll from a used car lot in 1968, Joplin engaged Dave Richards, a friend and roadie with her band, Big Brother and the Holding Company, to customize it with a psychedelic 'History of the Universe' mural, rendering it one of the first true 'art cars' and one of the most famous and important Porsches of all time.
