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 Macan spied, all lit up and dodging flurries

We've seen the upcoming Porsche Macan testing on surface roads and even on the Nürburgring, but here we have our first spy shots showing a disguised prototype doing some winter testing in snowy conditions. Still obscured by plenty of camouflage attempting to mimic its larger Cayenne sibling, we still can't get a clear look at what the Macan's face and rump are going to look like, although it does appear that some details for the front lighting are starting to emerge.
Below the headlights, those are obviously decals trying to look like turn signal lenses, but it appears that there is still some sort of lighting being hidden judging by the small circles cut into the camo. Lower in the fascia, we can also see there are LED running lights not revealed on past prototypes. The entire rear end of this Macan prototype still appears to be tacked-on camo, but the side view appears to be in production form save for the poorly disguised rear quarter windows.
As we've seen in the past, Porsche engineers are still testing the Macan alongside the Audi Q5 with which it shares its platform. There has been no word as to when we could expect to see the Macan in production or concept form, but we'd have to guess that this compact crossover is getting ready to shed its camo very soon.

Car owners getting more irritated with their repair experiences, study says

The J.D. Power U.S. Customer Service Index Study (CSI) is a barometer of a vehicle owner's happiness with the service experience. While it wasn't all bad in the 2023 study, the overall owner satisfaction score dropped. This year's tally of 846 out of 1,000 is two points down from 2022, the 43-year-old study's first decline in more than 28 years, and one point down from 2021. However, the overall score remains well up from the pre-pandemic scores of 821 in 2018 and 837 in 2020. The study claims the stumbling block is the horde of BEV launches. The flood into the new energy space has created a recall rate among EVs that's more than double the rate for ICE vehicles. Furthermore, dealership service department knowledge of EVs isn't on par with internal combustion engine expertise, leaving EV owners less satisfied with service advisors compared to ICE owners. Chris Sutton, VP of automotive retail at J.D. Power, said, "As training programs for service advisors and technicians evolve, EV service quality and customer experience must address both the vehicle and the unique customer needs. The EV segment has the potential to spur massive convenience improvements in how customers service their vehicles — but weÂ’re not seeing the benefits yet." Matters are slightly worse for all owners, though, with labor and parts shortages contributing to longer wait times for service appointments. The CSI study surveys owners and lessees of one- to three-year-old vehicles to gauge their happiness with service at franchised dealer or aftermarket service facilities for maintenance or repair work. The criteria in order of importance are service quality (32%); service advisor (19%); vehicle pick-up (19%); service facility (15%); and service initiation (15%). Lexus retains the top spot for luxury brands, giving it three wins in four years. The Japanese automaker won in 2020 as well, its run interrupted by Porsche in 2021. Cadillac, Infiniti and Acura complete the luxury top 5.  For mass-market cars, Mitsubishi wins again after a victory in 2021 and falling to fourth last year. It's followed by Mazda, Buick, Subaru and Mini.  Considering the different service needs and service experience of different body styles, the study has broken results out by segment for the first time. Lexus earned a second victory thanks to winning the premium SUV segment, and Mitsubishi earned a second victory by winning the mass-market SUV/minivan category.
