Porsche says turbo'd 911 engines will still be revvy

Porsche fans really, really don't like change. Remember when the 911 moved away from air-cooled engines? Now, as the company prepares to move the vast majority of the 911 line away from naturally aspirated powerplants, one of the brand's highest ranking officials is speaking out to prevent a similar outcry. Dr. Heinz-Jakob Neusser, the head of powertrain development for the Volkswagen Group and a board member of the VW brand, told Car that turbocharging won't take away from the rev-happy nature of Porsche's current engines. "Turbocharging is possible with higher revs – it's not true to say that turbocharged engines must stop at 6000rpm," Neusser told Car at the 2015 New York Auto Show. "That's not true... If you look at McLaren, they already have in production turbo engines with high revs." With turbocharged engines, Nuesser explains, there's no need to go for a super high redline, because engineers are trying to spread the torque over the entire rev range. "It makes no sense to go to 10,000 rpm with a turbocharged engine," Neusser told Car. The other big concern that comes with the switch to turbocharging focuses on the 911's iconic flat-six exhaust note. Maintaining the car's well-known acoustic character shouldn't be an issue, Neusser said. "Noise is not a problem," adding that the Volkswagen Group knows a thing or two about building sweet-sounding turbos. "Look at the 911 Turbo; it has an extremely expressive noise today – that is not a problem. At the other end of the scale, the Golf R has it too," Neusser told Car. "You won't miss character with turbos, I promise." According to Car, the new turbocharged engines will arrive later this year at the 2015 Frankfurt Motor Show, as part of the current 911's facelift.

J.D. Power: Vehicle dependability at all-time high, Lexus and Porsche lead

Each year, J.D. Power and Associates surveys original owners of three-year-old vehicles to find out what kinds of problems they have had experienced over the last 12 months, and then it uses this data to create its annual Vehicle Dependability Study. This means that the models in the 2013 study are 2010 model year vehicles, and J.D. Power rates each make as well as the top individual models based on how many problems were experienced per 100 vehicles (PP100).
Debunking the idea that carryover models are more dependable than new or updated models, the 2013 study found that the average carryover model experienced 133 PP100, while all-new or redesigned vehicles for the 2010 model year had 116 PP100; vehicles that received minor changes fared the best with just 111 PP100. The overall average for all makes was 126 PP100, which is the lowest figure since the findings were first issued in 1989.

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.
