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: Toyota FCV Rally Car To Compete, Barra bullish on Chevy Volt

The Toyota FCV will compete in the last stage of the 2014 Japanese Rally Championship. The sport-tuned hydrogen-powered car will tackle the 177-mile Shinshiro Rally on November 1 and 2, emitting no greenhouse gases in the process. The rally course will help prove the safety of the vehicle before it goes on sale in Japan in the next several months. The Toyota FCV, rumored to be called "Mirai" in Japan, will begin sales there before April, according to Toyota, and in the summer in the US and Europe. Read more in the press release below. Carsharing is becoming more popular, and more visible, throughout the world, including the US. According to WardsAuto columnist John McElroy, 18 percent of US drivers have used some sort of carsharing service. Additionally, he says 60 percent of Americans are familiar with Zipcar and Uber. Mercedes' Harald Kroeger says promotions like free parking for carshares in Stuttgart are encouraging growth for Daimler's carsharing service, Car2go. Read more at WardsAuto. Ethanol is being help up by rail transport, according to ethanol producer Green Plains. More and more stations are carrying E15 blend gasoline, but grain producers have complained that crude oil is given higher priority by the rail lines shipping it, which rail companies deny. Union Pacific and BNSF Railway say they are stepping up service to make sure that ethanol can be shipped reliably to customers. Read more at Omaha World-Herald. General Motors "has placed a significant bet [on] the electrification of the automobile," says CEO Mary Barra. In a speech to the Detroit Economic Club this week, she spoke about the Chevrolet Volt, and its importance to GM's future. While Barra admits the Volt's success has been "not everything we wanted," it has provided experience, and shows that EVs have "an important role in the future of GM." The new Volt is more refined, stores more energy, has longer range, uses less fuel and is a big investment for Michigan. She announced that the new Volt's electric drive system will be built in Warren, and that all of its major components will be made in Michigan. "Silicon Valley doesn't have a corner on the market for innovation, creativity and drive," says Barra. "These qualities exist here – in this region – as well."

Chevy murders out Trax crossover with new Midnight Edition

Leaning towards a new Chevy Trax, but think it needs a little bit more attitude? Chevy has you covered with the release of the new Midnight Edition. It's based on the Bowtie brand's smallest crossover, but injects some extra style with its murdered-out treatment. The new Chevy Trax Midnight Edition is based on the top LTZ trim, and upgrades with black wheels, bezels, molding, door handles, and more. Inside, the cabin is adorned with gray-accented seats and gray-piped floor mats. It isn't a huge transformation, but may be just the dose of attitude that Chevy's little crossover needs. Otherwise it's the same Trax introduced a year ago, and comes equipped with a 1.4-liter turbo four good for 138 horsepower and 148 pound-feet of torque. It's available in either front- or all-wheel drive, and will return a claimed 34 miles per gallon on the highway in the former setup. The Midnight package adds an extra $500 to the $26,125 base MSRP on a new Trax LTZ.

Based on the LTZ trim, the Midnight Edition features black wheels, bezels, beltline molding and door handles, along with a black rear license plate applique. Inside, the seats are trimmed with gray accents and the floor mats feature gray piping. "Introduced just a year ago, the Trax has quickly become an important vehicle for Chevrolet, bringing in new, younger and more female buyers to the brand," said Betsy Flegg, senior marketing manager, Chevrolet Crossovers. "The small SUV segment is the fastest growing in the industry and models such as the new Trax Midnight Edition provides customers an expressive option." Trax sales were 57,707 for the first 11 months of 2015, placing it second in the segment, with almost 20-percent market share. Chevrolet crossover sales were up 35 percent for the same period. Fusing small-car agility and utility convenience of an SUV, Trax offers up to 48.4 cubic feet of cargo space. A 1.4L turbocharged engine offers the efficiency of a small displacement engine – an EPA-estimated 34 mpg highway (FWD models) – with the power of a larger engine on-demand. Connectivity features include an available 4G LTE Wi-Fi hotspot.
