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 Colorado gets Midnight, Trail Boss editions

After introducing a gamut of special editions for the full-size Silverado, Chevrolet is offering a pair of new packages for its midsize Colorado. Following in the Silverado's footsteps, the Colorado Midnight Edition just blacks out all the things. There's a black grille, black Bowtie, and exclusive 18-inch wheels. They happen to be black, as well. In terms of functional changes, the Midnight Edition adds a spray-in bedliner, tonneau cover, and unique sill plates. Potential owners won't be limited on engine options and body styles here, as the blacked-out trim can be added to extended and crew cab bodies, in two- or four-wheel drive models, and with all of the pickup's available engines, including the upcoming Duramax diesel. The only limiting factor is the actual trim level – you'll need to settle for the mid-grade LT. Don't worry, though. The heftier, top-of-the-line Z71 will be offered with its own unique package, called the Trail Boss. As expected, it goes big on off-road character, with LED trail lighting and aggressive Goodyear Wrangler DuraTec tires. There are also black 17-inch wheels, newly flared fenders, side steps, and like the Midnight Edition, a blacked-out grille and spray-in bedliner. Also like the Midnight Edition, the only limit to adding the Trail Boss is that you opt for the Z71 trim. Engines, drivetrains, and body styles are not fixed. Look for both trucks at your local Chevrolet dealer this fall. Until then, scroll down for the official press release. 2016 Chevy Colorado Special Models Dressed to Impress Midnight Edition, Z71 Trail Boss complement capability with customized style 2015-08-03 DETROIT – On the street or on the trail, the 2016 Chevrolet Colorado's Midnight Edition and Z71 Trail Boss bring bolder choices to customers looking to make a visual statement with their truck. The special editions roll into Chevrolet dealerships this fall, with distinctly tailored appearances that blend custom design cues with Colorado's popular options and accessories. The Midnight Edition evokes the aesthetic of an urban tuner vehicle, while the Z71 Trail Boss is designed for terrain where the pavement ends. "These are aggressive editions of one of the country's hottest-selling truck, demonstrating the personalization that's possible with Chevrolet accessories, whether it's for the street, trail or both," said Tony Johnson, Colorado marketing manager.

Chevy Trax engineer says GMC version possible

The Buick Encore is doing so well and its platform-mate the Chevrolet Trax has such good reviewer vibes going for it already, that a GMC version hasn't been ruled out. During the recent press launch, Automotive News asked lead engineer Al Manzor if the Trax could wear a GMC-branded suit, to which Manzor replied, "I think that is certainly possible." That's a long way from telling us anything about the probability of a GMC version of the Trax, and a legion of questions would need to be answered before it could happen. How would a GMC version be priced to leave room for the $26,465 GMC Terrain but not eat into sales of the $20,995 Trax or the $24,035 Encore? Or would that matter? Could it primarily be considered to encourage a new faction of The Yukon Set at the compact end, GMC buyers being famously committed to the marque? And of course, would there be a Denali version? It'll probably be a long while before we have any kind of answers, but if you want to see it happen, the door to your campaign of persuasion is at least ajar.
