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.

GM to cut production at 5 plants in North America, kill several models

DETROIT/WASHINGTON — General Motors Co said on Monday it will cut production of slow-selling models and slash its North American workforce in the face of a stagnant market for traditional gas-powered sedans, shifting more investment to electric and autonomous vehicles. The announcement is the biggest restructuring in North America for the U.S. No. 1 carmaker since its bankruptcy a decade ago. GM said it will take pre-tax charges of $3 billion to $3.8 billion to pay for the cutbacks, but expects the actions to improve annual free cash flow by $6 billion by the end of 2020. GM plans to halt production next year at three assembly plants: Lordstown, Ohio, Hamtramck, Michigan, and Oshawa, Ontario. The company also plans to stop building several models now assembled at those plants, including the Chevrolet Cruze, the Cadillac CT6 and the Buick LaCrosse, the sources said. Sources said the Chevrolet Volt, Impala and Cadillac XTS would also be discontinued. Signs of the demise of six passenger-car models have been swirling since July. Plants in Baltimore, Maryland, and Warren, Michigan, that assemble powertrain components have no products assigned to them after 2019 and thus are at risk of closure, the company said. It will also close two factories outside North America, but did not identify those plants. The AP reported that 14,700 jobs would be affected. Some 8,100 of those would be white-collar jobs reduced through buyouts or layoffs. The No. 1 U.S. automaker signaled the latest belt-tightening in late October when it offered buyouts to 50,000 salaried employees in North America. The company also said it will cut executive ranks by 25 per cent to "streamline decision making." Some 6,000 factory workers could lose their jobs or be transferred to other plants. Its shares were last up 6.2 percent at $38.16. Tariff 'headwinds' and cost-cutting GM Chief Executive Officer Mary Barra told reporters on Monday the company can reduce annual capital spending by $1.5 billion and increase investment in electric and autonomous vehicles and connected vehicle technology because it has largely completed investing in new generations of trucks and sport utility vehicles. Some 75 percent of its global sales will come from just five vehicle architectures by early in the 2020s. It plans to reduce annual capital spending to $7 billion by 2020 from an average of $8.5 billion a year during the 2017-2019 period.

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.
