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.

Recharge Wrap-up: BMW cars to share i tech, Jordan to build solar EV charging network

Jordan is looking to promote EVs and build a solar charging network. The country is waiving import tariffs on electric cars, and is spending $120 million on solar chargers. It plans to build 3,000 charging stations, along with 30 MW of solar power. Some chargers will be powered by solar canopies, while others will get electricity from nearby solar farms. Jordan's solar plan should also help to lessen the amount of energy it needs to import from nearby countries. Read more from Navigant Research, or at Green Car Reports. BMW's mainstream cars will benefit from technology borrowed from the i3 and i8, according to BMW sales head Ian Robertson. In an interview with Automotive News, Robertson said that next-generation cars will use carbon fiber more extensively, and that more cars will get plug-in technology. He said that about half of i3 buyers opt for the range extender and added that it is incorrect to refer to a range-extended electric vehicle as a plug-in hybrid. Read more at Automotive News. The ethanol market should remain healthy despite falling oil prices. While cheap oil could drive down ethanol prices, demand still remains due to the federal biofuels standard. Additionally, ethanol producers may find it cheaper to ship their products as domestic oil production drops and railroad shipping opens up. Ethanol byproducts like distillers grains continue to sell, and foreign demand continues as other countries impose their own renewable fuel standards. Read more at Yahoo News. Via Motors will launch the production of an electric Chevrolet Silverado. The company will convert the pickups into range-extended EVs at its assembly line in Mexico, near GM's Silverado plant. Via has the capacity to produce 10,000 vehicles per year at its Mexico facility. Via Motors Chairman (and former GM Vice Chairman during the early days of the Chevrolet Volt project) Bob Lutz wants to help make EVs mainstream in America, and believes that requires electrifying pickups and SUVs.

Renault Scenic EV takes first place as (European) Car of the Year

The automobile awards season may not be over, but two of the more prestigious annual races came closer to a climax this week. One might need a scorecard to keep track. We’re focused here on two events: the World Car of 2024, now reduced to three finalists in six categories. Then thereÂ’s the Car of the Year, known in some quarters as the European Car of the Year. Except that the car doesnÂ’t have to be European to win, only sold there. Got that? Winners out of the way first: At the Geneva Motor Show on Monday, the Renault Scenic E-Tech all-electric has been voted Car of the Year 2024. The Scenic is a fairly compact, somewhat stylish SUV for Europe only, and is the seventh vehicle from the French brand to win the award. It sells in the United Kingdom for about $47,500. The other six finalists that had made the first cut of voting in November were the BMW 5 Series, BYD Seal, Kia EV9, Peugeot E-3008/3008, Toyota C-HR, and Volvo EX30. The trophy winner was chosen by a jury of 59 motoring journalists from 22 countries. Scenic came in first place with 329 points. The Seal was the first Chinese-made car to make this awardÂ’s shortlist; it finished sixth out of seven, just up from the Toyota. One judge explained his decision to grant the Seal zero votes. Writing in Top Gear, Paul Horrell wrote this entertaining critique: “It looks good and is well specified, so makes a strong market entry. The advanced electric system and cobalt-free battery are commendable too, and it's enjoyable enough to drive quickly. That's undermined by an agitated ride over bumps, and the logic of screens and switches is pretty eccentric.” Recapping the World Car of the Year 2024 update, the sponsors shared the stage at Geneva on Monday with the Europeans as well, although they revealed only the top three finalists in six categories. For the ultimate prize, they are the Kia EV9, the Volvo EX30 and the BYD Seal. The winners will be announced March 27 at the New York International Auto Show. Here's more on the World Car finalists.
