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.

Alpina D3 may be coming to Frankfurt with 350 hp, AWD

Rumors are swirling that Alpina, the tuning house that specializes in all things BMW, will followup its Geneva debut of the B3 Bi-Turbo with an oil-burning variant slated for debut at September's Frankfurt Motor Show. The news comes from Auto Zeitung, which reports that the second-generation D3 will be based off the Europe-only 335d.
This is a departure from the last D3, which had the four-cylinder turbo-diesel from the BMW 123d in a 3 Series body. The new model is expected to use a 3.0-liter, twin-turbocharged inline-six, which will generate 350 horsepower and 516 pound-feet of torque. That should scoot it to 62 miles per hour in under five seconds (likely while towing a tree stump). Both rear- and all-wheel drive should be available on the D3, and we imagine the thrill of this much power channeled through just the two rear wheels to be akin to skydiving sans parachute.
For our European friends that want an Alpina D3, but don't need more torque than any American full-size pickup, there may be plans to offer a four-cylinder variant that still delivers Alpina performance without a compromise in economy. We'll have more on the Alpina D3 when it debuts at the 2013 Frankfurt Motor Show.

2023 J.D. Power APEAL Study shows new-car customer satisfaction scores slip

J.D. Power survey results have been slightly up but mostly down for automakers this year, literally. In February, the 2023 Vehicle Dependability Study showed an overall decline compared the 2022 a month before the Customer Service Index Study did the same. The trend reversed in June with a better overall score on the 2023 U.S. Electric Vehicle Consideration Study than in 2022, then declined again the same month on with a lower overall score on the 2023 Initial Quality Study. The declines continue with the 2023 J.D. Power U.S. Automotive Performance, Execution and Layout (APEAL) Study, overall satisfaction among the 84,555 respondents down two points overall compared to 2022, to 845 out of 1,000 points. Because last year's score dropped compared to 2021, this year marks the first consecutive decline in the study's 28-year history. The study tries to "[measure] owners' emotional attachment and level of excitement with new vehicle" after 90 days of ownership by asking new owners to rate 37 attributes in 10 areas around the vehicle, such as the feeling they get when they hit the accelerator. Satisfaction with nine of the attributes is down this year versus last, fuel economy the only segment to show better results with 15 points more satisfaction. Styling and infotainment are big drags on satisfaction. Responses to new car exterior looks tallied 888 points, down from 894 last year, the largest drop in this year's study. On the digital side, less than half of those surveyed this year said they prefer using a manufacturer's built-in infotainment. From 70% of respondents in 2020 preferring to use a manufacturer's in-house software to play audio instead of Android Auto or Apple CarPlay, that's 56% in 2023. Going all-in on Google appears to have the best effect. J.D. Power said that vehicles with both Google's Android Automotive Operating System (AAOS) and Google Automotive Services (GAS) "score higher in the infotainment category than those with no AAOS whatsoever. AAOS without GAS receives the lowest scores for infotainment of the three categories."  Frank Hanley, senior director of auto benchmarking at J.D. Power, said, "Despite the technology and design innovations that manufacturers put into new vehicles, owners are lukewarm about them. While innovations like charging pads, vehicle apps and advanced audio features should enhance an owner’s experience, this is not the case when problems are experienced.
