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.

2015 Chevy Silverado gets Custom Sport package

It's been on our mind for a couple of years that the Chevrolet Silverado could really use "a sophisticated monochromatic look." It is, at long last, a reality. Harking back to the Custom Sport Trucks the company produced in the 1960s, the 2015 Custom Sport package can be had in black or white on LT and LTZ models for those in search of "a touch of elegance." That means body-colored front and rear bumpers and grille surround, a black grille, and chrome applied to the door handles, mirror caps, side moldings and 20-inch wheels. The package, which will cost between $1,950 an $2,950, also throws in projector beam headlamps, tow hooks, and heated mirrors. LT trims can be had in black or white, LTZ trims - including Z71 - offer the choice of black or White Diamond Tricoat. The press release below has more information. Don't everybody rush to the dealer at once. 2015 SILVERADO OFFERS CUSTOM SPORT PACKAGE Inspired by Chevy Custom Sport Trucks that helped launch personal-use pickups DETROIT, 07/01/15 – With the new 2015 Silverado Custom Sport special edition, Chevrolet pays homage to one of its most iconic pickups, adding a sophisticated monochromatic look to double- and crew-cab Silverados. The Custom Sport package features body-colored front and rear bumpers and a body-colored grille surround with a chrome-accented black grille. Other accents include 20-inch chrome wheels, chrome door handles and mirror caps, and chrome body-side moldings. The package also includes projector beam headlamps, tow hooks and heated power-adjusted mirrors. "The Custom Sport special edition was inspired by Chevy Custom Sport Trucks of the late 1960s," said Sandor Piszar, Chevrolet Trucks marketing director. "Those CST models added a touch of elegance to a great all-around truck, just like the Custom Sport package for the new Silverado." The redesigned 1967 Chevrolet pickup entered the market at a time when trucks were starting to move off the jobsites and into the driveways of cities and suburbs. The 1967 Custom Sport Truck, with its bright trim, plush carpet and bucket seats, helped launch a wave of personal use pickups that continues today. For the 2015 Silverado, the Custom Sport package will be available as LT and LTZ models, including Z71s. LT models will be available in black or white, while LTZs will come in black or White Diamond Tricoat. Package prices will vary from $1,950 to $2,950, depending on the model. Dealers can place orders starting this month.

GM recalls over 323,000 HD pickups because tailgates can open unexpectedly

General Motors is recalling more than 323,000 heavy-duty pickup trucks in the U.S. because the electronic tailgate release switches can short circuit and open the gates while the vehicles are in park. The recall covers certain Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks from the 2020 through 2024 model years. The National Highway Traffic Safety Administration says in documents posted on its website Tuesday that water can get into the switches and cause the tailgates to open when in park gear. The agency says that can result in unsecured cargo falling out of the beds, creating a road hazard and increasing the risk of a crash. GM is advising owners to check that the tailgate is closed and latched before they drive the trucks. Dealers will replace an exterior touchpad switch. Owners are to be notified by letter starting March 18. GM dealers also have been told to stop selling affected vehicles until repairs are made. The company says in documents that it has 136 complaints about the tailgates opening unexpectedly. GM reported one complaint of a minor injury and three complaints of minor property damage.
