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.

Buick takes top spot in 2022 J.D. Power Initial Quality Study

People, economies, and supply chains weren't the only things continuing to get sick over the past year. The 2022 J.D. Power Initial Quality Study (IQS) is out, showing the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership increased overall. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. This year, the average jumps to 180 problems. J.D. Power says that figure is a record high over the 36-year history of the study. Buick leapt to the top of the rankings this year with the fewest issues, at 139 problems per 100 vehicles in the first 100 days of ownership. After Dodge became the first American automaker to lead the IQS in 2020, followed by Ram in 2021, this year marks a three-peat for U.S. carmakers. Dodge took second this year at 143 PP100, Chevrolet third with 147 PP100, Genesis the first luxury maker on the chart in fourth with 156 PP100. Between February and May, this year's study gathered responses to 223 questions from more than 84,000 new 2022-model-year car owners and lessees. The questions are designed to zero in on real-world problems new owners encounter with nine categories of vehicle features: Infotainment; features, controls and displays; exterior; driving assistance; interior; powertrain; seats; driving experience; and climate. As has been the case in the past few year, infotainment has proved to be the most problematic bugbear making scores worse. Considering features individually, six of 10 of the worst problem areas dealt with infotainment, causing infotainment's score of 45 PP100 to be 19.5 PP100 worse than the second-placed feature. Consumers ranked getting Android Auto and Apple CarPlay to connect reliably as the most troublesome.  GM didn't just score with Buick, which was one of only nine of the 33 ranked brands to show improvement this year. The conglomerate earned first place with the fewest PP100 among all the automaker groups, and scored the most model-level awards with nine, ahead of BMW with eight and Hyundai Group with three.  This year's study again showed a gap between luxury and mass-market makers, thought to be down to the amount of tech in luxury vehicles that consumers aren't properly informed about or that doesn't act as expected — that latter issue exacerbated by the chip shortage.

2016 Chevy Malibu undercuts rivals with $22,500 starting price

Customers eager to get their hands on the new 2016 Malibu may be pleasantly surprised to find that Chevy has actually reduced the price on the base model. In fact the Malibu now undercuts much of the competition. Order up a new Malibu in entry-level L trim and you'll shell out only $22,500. That includes the $875 destination charge (which is $50 more than what Chevy used to charge for delivery). The Malibu L of course won't come with all the bells and whistles of the higher trim levels, but still comes with 10 airbags, cruise control, and push-button ignition. Compare that to the competition and you'll find the base Malibu less expensive than most, but not all. It undercuts the Ford Fusion, Honda Accord, Toyota Camry, and Nissan Altima – although the Hyundai Sonata and Mazda6, for example, are still marginally less expensive in base trim. Those looking for a little bit more can upgrade to the Malibu LS ($23,995), LT ($25,895), or Premier ($31,795). The L, LS and LT come with a 1.5-liter inline-four, but the Premier packs a 2.0-liter turbo that can also be had in LT spec for $29,495. Pricing for the Malibu Hybrid is slated to be announced at a later date, as will EPA fuel economy figures for the rest of the range. Next-Gen Chevrolet Malibu Starts at $22,500 Lower than Camry, Accord, Fusion and Altima 2015-09-10 DETROIT – The 2016 Chevrolet Malibu, the most fuel-efficient, connected and technologically advanced version in the nameplate's history – will be available with a starting suggested retail price of $22,500 for the L model. "We've continued our focus on delivering on the highest levels of quality, as evidenced by recent recognitions from J.D. Power on initial quality and long-term dependability," said Steve Majoros, director of Chevrolet cars and crossovers. "The 2016 Malibu is engineered and priced to give customers impressive value and technology that's hard to compete with." For 2016, Malibu will be offered in five models, L, LS, LT, Hybrid and Premier. Standard equipment includes 10 airbags, cruise control, push-button start with passive entry and fuel-saving stop/start technology on the base 1.5L 4-cylinder engine. The LS model, starting at $23,995, includes standard Chevrolet MyLink Radio with 7-inch diagonal color touch screen, available compatibility with Apple CarPlay and Android Auto and a rear vision camera.
