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.

BMW considering North American engine plant?

BMW may be set to expand its US operations with a new engine plant, Bloomberg reports. The Bavarian automaker already has its Spartanburg, SC factory which builds the company's X3, X5 and X6 crossovers. According to the story, Mexico is also under consideration for the BMW engine factory, with the report claiming a final decision will be made in 2014.
"Establishing local motor manufacturing abroad is more complex than assembling cars, but it's a logical step for them to eventually start making engines in markets where they're expanding vehicle production," Juergen Pieper, an analyst for Bankhaus Metzler tells Bloomberg. Building engines in the US or Mexico would save BMW from having to ship engines for some of its most popular models across the Atlantic.
BMW, for its part, hasn't said anything concrete. Spokesman Mathias Schmidt is quoted in the story saying, "As part of our long-term growth strategy, we're frequently looking at different countries for possible locations of future production facilities. No decisions have been made yet, though, for an additional plant."

BMW tops Consumer Reports 2023 Brand Report Card

Feels like we wrote about Consumer Reports' 2022 Brand Report Car and 10 Top Picks a few weeks ago, but it was last April. So the mag is back with a ranked roster of 32 brands and 10 vehicles in four categories for your debating pleasure. Starting with the brands, last year's top three were Subaru, Mazda and BMW. This year, the Munich crew climbed two spots to win the prize thanks to "Superb road test scores and solid results in CR’s reliability and owner satisfaction surveys." Subaru narrowly fell to second, maintaining its four-year run in the top three. Mini, eighth last year, jumped five spots to get the last step on the podium. The rest of the top 10 were Lexus (up one spot from last year), Honda (down one spot from last year), Toyota (up three), Genesis (up 12), Mazda (down six), Audi (down three) and Kia (up eight). The magazine and testing outfit says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CRÂ’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." Last year's top 10 had six automakers from Japan, three from Germany (giving Mini credit for England), none from the U.S. or South Korea, and five luxury brands. This year's list counts five makes from Japan, two from Germany because Porsche fell out of the top ten, two from South Korea, still none from the U.S., and four luxury brands. Buick again ranked as the best domestic, dropping to 12th after being 11th last year. The big mover was Lincoln, its 10-place jump up to 16th attributed to better reliability from the Corsair and Nautilus. Tesla's improved overall reliability saw it climb six spots to 17th. Dodge climbed one spot to 15th. Jeep got out of the penalty box in last to come second-to-last. Land Rover fell three places into the penalty spot.  CR's top 10 vehicle models The 10 Top Picks list is practically a new list. Only two holdovers made it to 2023, those being the Subaru Forester and Kia Telluride.
