More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.

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 investing $439 million in Corvette plant

General Motors is slowly trickling out announcements about its $5.4 billion in US plant upgrades over the next three years. The latest one is something that fans of one of America's most beloved sports car will be happy about. The Bowling Green, KY, factory that assembles the Chevrolet Corvette is receiving $439 million of those funds to build a new paint shop. Covering 450,000 square-feet, the site will make painting the 'Vette more efficient and environmentally friendly. The upgrades there include robots that use paint more effectively, technology to eliminate sludge water, LED lighting to improve inspections, and less energy-intensive baking ovens. While the groundbreaking is already complete for the building, full construction is expected to begin this summer and take two years. This is the biggest upgrade for the Kentucky factory in a few years. In preparation for the latest Corvette, the Bowling Green plant received $131 million in 2011 for upgrades and to add more workers there.

Now they can dream about more painstakingly precise pigments, thanks to a new paint shop that is among $439 million being invested at the only plant in the world that builds Chevrolet's iconic sports car. General Motors announced the moves today that include retaining 150 jobs and building the 450,000 square-foot paint shop that is almost half the size of the entire current production facility. The investment builds on approximately $135 million GM has invested in the plant over the last four years for the new Corvette Stingray and Performance Build Center. The announcement was followed by a groundbreaking event for the new paint shop. "The Corvette is one of Kentucky's most-cherished icons," said. Lt. Gov. Crit Luallen. "Such a significant expansion of the Bowling Green Assembly Plant will help the company remain competitive in the region and around the world." Construction of the new paint shop, which includes substantial technology upgrades, is planned to begin this summer and take approximately two years to complete. Corvette production schedules will be unaffected by the construction.
