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: Tesla opens 50th European Supercharger, BMW smart charging in Singapore

Southeastern Illinois College wants to create a biofuel processing certification program. The school is waiting to hear about receiving $750,000 from a US Department of Labor grant that would allow it to expand its Biofuels Education curriculum to include certification for manufacturing biodiesel and ethanol. There are currently no such programs in existence, and its development would require Labor Department approval as well as input from biofuel companies. Southeastern Illinois College believes that biofuel processing certification would be a large draw for potential students. Read more at The Southern Illinoisan. Tesla has opened the 50th Supercharger in Europe. In the year since the first on was installed in Norway in August 2013, Tesla has been building the network that, like it does in the US, will allow Model S drivers to go long distances for free. There are now 168 Superchargers open throughout the world. Find more in the press release below. BMW is partnering with Greenlots to bring an open standards EV charging network to Singapore. As part of BMW's 360 Electric program, Greenlots will install public chargers and manage the network that allows BMW i owners to find and use the chargers with BMW's navigation system and ChargeNow card. The 30 possible public chargers Greenlots plans to install will use the company's SKY Smart Charging platform. Greenlots will also install the BMW i Wallbox Pure charger at customer's homes and offices. Read more in the press release below. Plug-in electric vehicle (PEV) sales are forecast to reach 1.8 million a year by 2023, according to a report by Navigant Research. Right now, North America is the biggest buyer of battery-electric and plug-in hybrid vehicles, but that should change as the Asia Pacific market is expected to outgrow it; still, the US alone is expected to have more than 2.7 million PEVs on the road in 2023. Urban areas are where we'll see the largest concentration, naturally, with Tokyo, Los Angeles and Paris having the most sales in 2023, respectively. With the increase in PEVs comes an increase in residential load on the electric grid, which is expected to rise by 33 to 37 percent. Read more at Hybrid Cars, or head to the Navigant Research website. Chinese automaker Dongfeng is now manufacturing its first mass-produced electric vehicle, the Aeolus E30. The small, two-seat urban EV has a limited speed of 50 miles per hour, but has a range of up to 100 miles.

2015 will be the biggest year ever for cars at CES

Like the SEMA Show, major automakers are paying increasing attention to the CES, with 2015 expected to be one of the most auto focused yet. Ford, Volkswagen, Toyota, General Motors, Hyundai, Mazda, Audi, BMW and Fiat Chrysler Automobiles will all be in attendance when CES 2015 kicks off next week, taking up a record-breaking 165,000 square feet of space at the Las Vegas Convention Center. "We've come a long way from a single car on a carpet," Ford's Alan Hall told Bloomberg. Unlike SEMA, or a more traditional auto show, like the upcoming festivities in Detroit, CES doesn't necessarily focus on entire cars or the way they perform, but on the way our technology will interact with vehicles, and in how those vehicles will deliver information to drivers. "CES has become a major launch point for a lot of the big automakers," IHS tech analyst Mark Boyadjis told Bloomberg. "CES is a way for them to get on a global stage for technology." As for what kind of wares automakers will trot out in Las Vegas, we already know that BMW will show off an autonomous i3 electric car that can navigate its way through a multistory car park and can be hailed via a smartwatch app. According to Bloomberg, Hyundai will show off its own smartwatch app for the Genesis sedan, while Audi and Mercedes-Benz will show off autonomous vehicles next week. Automakers won't be the only companies looking to capitalize on CES. Tech firms, like chipmaker Nvidia, are becoming increasingly involved in the automotive game and will be in town showing their wares off to OEMs. "Two years ago, our booth would have been filled with PCs and people playing video games," Danny Shapiro, Nvidia's senior director for automotive business, told Bloomberg. "This year we made a strategic decision to shift the focus of the booth on automotive and de-prioritize some of the other things." Needless to say, you can expect to see a lot of news out of Las Vegas come next week. Stay tuned.
