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.

Volvo, Kia and BYD duke it out in the finals for World Car of 2024

Three electric vehicles — none produced by an American manufacturer — will compete next month for the title of 2024 World Car of the Year, it was announced Monday. The finalists are the Kia EV9, the Volvo EX30 and the BYD Seal (shown above). The latter two are built in China. The three top finalists in five other categories were also named at the Geneva Motor Show in Switzerland. The winners in all six categories will be revealed live during an awards ceremony at the New York International Auto Show on March 27. This year marks the 20th year of the World Car Awards and the partnership with the New York show. Besides car of the year, the other finalists are: Electric vehicle: BMW i5, Kia EV9, Volvo EX30; Luxury car: BMW 5 Series/i5, Mercedes Benz E-Class, Mercedes Benz EQE SUV; Performance car: BMW M2, BMW XM, Hyundai Ionia 5 N; Urban car: BYD Dolphin, Lexus LBX, Volvo EX30; World Car Design: Ford Bronco, Ferrari Purosangue, Toyota Prius. Only Ford among U.S. companies has an entry in the final selections, and only in one category, design, for the Bronco. BMW has four vehicles in the finals, Volvo has three, Kia and Mercedes have two each. BYD from China has two entries as well. The Seal went on sale in in its home market in 2022 and is now available in most of the rest of the world. The BYD Co. (which stands for Build Your Dreams) has surpassed Tesla to become the worldÂ’s biggest maker of electric vehicles, and has its sights set on the U.S. The selection process for World Cars involves 100-plus automotive journalists from 29 countries who vote, as they review and test-drive the eligible vehicles for the 2024 awards. Their journey is captured virtually on World Car TV. Design/Style Geneva Motor Show BMW Ferrari Ford Hyundai Kia Lexus Mercedes-Benz Toyota Volvo Best Cars World Car of the Year

2015 BMW i8 sets everyone's tongues wagging in Northern Michigan

Like few other cars we can remember, people want to talk about the 2015 BMW i8. Drive one, and you'll soon find out what we mean. They stop you at gas stations. They accost you in Walgreen's parking lots. They stream out of neighborhood bars, beers in hand.
At least, that was our experience this week during Autoblog's Technology of the Year testing. We had the pleasure of driving the plug-in hybrid BMW sports car up to and around Petoskey, MI, a resort town where seeing such exotics is rare enough, let alone in the off season. It made for some interesting conversations - so we began writing down some of the comments the butterfly-doored coupe inspired. Here's a sampling:
"Wanna race for pinks? I'll go easy on you." - Acne-covered teenage pizza delivery driver in a sad-looking Ford Taurus parked at a Valero gas station near Grayling (which incidentally didn't actually have gas).
