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.

Chevy to reveal new Spark in Seoul and New York

Chevy is preparing to roll out an all-new Spark next month, giving us a taste of things to come with the teaser image above. The new Spark is set to debut simultaneously at car shows in Seoul and in New York on April 2, joining the new Malibu that will also mark its debut at the Manhattan expo. Why introduce the new Spark at the same time in South Korea and in the US, you ask? Probably because those are the two biggest markets for Chevy's smallest car, accounting for the lion's share of the 1.1 million units sold in 71 markets around the world since its introduction in 2009. Chevy hasn't revealed much about the new Spark, except to say that its styling will be more sophisticated than the "youthful whimsy" of the current model. A Spark of Sophistication Chevrolet's redesigned global minicar to debut in Seoul and New York on April 2 2015-03-09 DETROIT – The all-new 2016 Spark will debut on April 2 at the Seoul and New York auto shows, Chevrolet announced today. A sleeker, more aerodynamic profile and a progressive take on Chevrolet's signature design cues will give the redesigned Spark a more sophisticated aesthetic that reflects the changing tastes of the global minicar market. "The new Spark's design has evolved and grown up with the segment," said Michael Simcoe, GM International vice president of Design. "The youthful whimsy of the original Spark is still in its genes, but it is conveyed in more traditional proportions that reinforce the customer's refined expectations." Chevrolet has sold more than 1.1 million Sparks around the world since it went on sale as the Beat in India in late 2009. Today, the Spark is available in 71 markets worldwide, selling the most in South Korea, followed by the United States and Mexico. Spark is attracting younger and first-time car buyers to Chevrolet with 26 percent being under the age of 35. Sales of the Spark in the U.S. are up 32 percent in the first two months of 2015 versus the same period in 2014. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 115 countries and around 4.8 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature engaging performance, design that makes the heart beat, passive and active safety features and easy-to-use technology, all at a value.

GM CEO to meet with U.S. lawmakers over job cuts

WASHINGTON — General Motors Co Chief Executive Mary Barra plans to visit Capitol Hill next week to discuss the company's plans to halt production at five plants in North America next year and cut up to 15,000 jobs, two congressional aides said on Friday. GM has come under harsh criticism from lawmakers from both major political parties, and from President Donald Trump, since Monday when it announced the biggest restructuring for the U.S. No. 1 carmaker since its bankruptcy a decade ago. Barra is expected to meet with lawmakers from Michigan and Ohio, where GM plans to shutter three plants, as well as senior leaders in Congress. GM did not immediately comment. Barra has been calling lawmakers this week to explain the decision to end production. Trump has threatened to revoke subsidies for GM. The Detroit automaker plans to halt production next year at three assembly plants: the Lordstown small-car factory near Youngstown, Ohio; the Detroit-Hamtramck complex in Detroit; and the Oshawa, Ontario, assembly complex near Toronto. It will also stop building several models now assembled at those plants, including the Chevrolet Cruze, the Chevrolet Volt hybrid, the Cadillac CT6 and the Buick LaCrosse. Additionally, GM plans to shutter the Warren transmission plant outside Detroit and a plant that makes electric motors and drivetrains outside Baltimore, Maryland. The Cruze compact car will be discontinued in the U.S. market in 2019, although GM may continue building it in Mexico for other markets, Barra said. Reporting by David Shepardson. Related Video:
