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.

First 2015 Chevy Corvette Z06s en route to owners [w/video]

Pretty much right on schedule, Chevrolet has begun shipping the very first customer examples of its 650-horsepower, supercharged Corvette Z06. In fact, according to General Motors, the earliest Z06s could be in customer hands by the end of this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, manager of Chevy's Bowling Green Assembly plant. "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." Prices for the Z06 start at $78,995 for the hardtop model, while the first-ever Z06 Convertible kicks off at $83,995. Take a look below for the official press release from Chevrolet, and while you're down there, we've slipped in a new video of Corvette Racing's Tommy Milner taking a hot lap of Road Atlanta in a Z06, complete with some Performance Data Recorder footage. First 2015 Corvette Z06s on Their Way to Customers Most capable model in Chevrolet's history now shipping from Bowling Green BOWLING GREEN, Ky. – Chevrolet is now shipping the all-new 2015 Corvette Z06 coupe from Bowling Green Assembly and some early customers could receive the much-anticipated supercar later this week. "It has been an incredible opportunity to work on Chevy's most capable model," said Jeff Lamarche, plant manager of General Motors' Bowling Green Assembly plant, "It truly is an amazing car, and we're thrilled to get them into the hands of our eager customers." The new Corvette Z06 offers the most choice for customers in the model's history. It is the first Z06 to offer an available eight-speed paddle-shift automatic transmission and, thanks to a stronger aluminum frame, a removable roof panel. In addition, it is the first time since 1963 that the Z06 is available as a convertible – which will arrive in early 2015. The new LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm – making the 2015 Corvette Z06 the most powerful production car ever from General Motors and one of the most powerful production cars available in the United States. To balance performance and efficiency, the LT4 leverages a trio of advanced technologies – direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing –with a new, more efficient supercharger. The LT4 helps make the Corvette Z06 the most capable car in the brand's history.

Basic configurator for 2021 Chevy Colorado and GMC Canyon slips online

TFLnow discovered basic configurators for the 2021 Chevrolet Colorado and GMC Canyon are already online at GM's site for employee discounts. These aren't the fully-featured whiz-bang configurators that will show on the retail websites soon, but they include a bunch of the relevant info a shopper would be looking for. After trim changes detailed earlier this year, the 2021 Colorado offers the most choice, even with the two-door base model gone. Cutting the entry-level Colorado also means the entry-level price has gone up by $3,900; the 2020 Colorado could be had for $22,495, but the 2021 model starts at $26,395 after the $1,195 destination charge. That gets you the extended cab with a standard bed in two-wheel drive. The 2WD crew cab with a short bed starts at $28,295, and the 2WD crew cab with a standard bed starts at $30,595. At the top end, the ZR2 model runs $44,395, which is $200 more than the 2020 version. The color palette isn't complete, but the options page shows a number of choices for packages. The Redline Special Edition Package goes up $10 to $2,690, the Tonneau and Step Package increase $100 to $1,195, a new Chrome Package puts shiny stuff in places like the door handles and steps for $300, while the Black Bowtie Emblem Package drops $80 to $140. The one-inch front leveling kit, which was thought to cost $150 based on early order information GM Authority had seen, is here listed for $450 and available on the Colorado but not the Canyon.  The Canyon makes matters a tad simpler by having many options locked in depending on which one starts with — 2WD Elevation Standard starting at $27,595, 2WD Elevation for $31,195, 4WD AT4 with a cloth interior for $39,395 or AT4 with leather for $41,195, the least expensive Denali starting at $42,095 for a crew cab short box with 2WD. The Elevation includes items like the Convenience Package that are options on the base model, and also offers a $1,400 High Elevation Package conferring heated and power black leather seats, plus a heated steering wheel, that can't be optioned on the Elevation Standard. The pinnacle is the crew cab with a standard bed in Denali 4WD trim for $45,895. Colors and many of the final options and accessories, such as the AT4 Off-Road Performance Edition Package we've heard about, are also missing here, but there's heaps to play around with to get an idea of what you'll be in for if you're considering a 2021 Canyon.
