2015 Chevrolet Corvette Z06

"Corvette" has stood for American muscle, American sports car, and American supercar. In many cases, it still stands for America: liberty on the go, LS-powered freedom. There was also a time when it meant really impressive numbers that didn't equate to really impressive handling, and a not-so-nice cabin. The handling issue really turned the road-legal corner when the C5 Z06 was introduced in 2001, and by the time the super-duper ZR1 ended its run in 2010, Corvette had exorcised practically all of its dynamic demons. But when I took a seat in the 2015 Corvette Z06 on the first day of my week-long loan, I espied a few demons still squatting in the interior. When colleague Seyth Miersma drove the Z06, he wrote, "Listen, I'm not going to be the guy that dogs the Corvette for having a cheap-feeling interior, this generation has put those once-legitimate claims to rest." Well, I am going to be that guy, because I don't think those claims have been put to rest. One day Chevy will give us leather that looks and feels like leather, instead of the astonishingly thin hide that is laid directly on top of the instrument panel structure. This material was set off by white stitching, but there were no seams, just a trail of white stitches. In some places it was hard to tell where the leather ended and the plastic began; or it might all have been the same upholstery, I don't know. Five dollars of foam padding would add five thousand dollars of luxury to the cockpit. One day Corvette will have plastics that don't look so plasticky. I know General Motors can do it. And after years of thinking Corvette seats were too wide and flat, this latest Z06 is almost there. The seatbacks were nice, but the exaggerated side bolstering on the seat bottoms was too narrow and sharp. That's a personal preference, though; other drivers with thinner thighs will think differently. My complaint isn't that the interior isn't luxurious, it's that it's not luxurious enough. If Chevrolet was worried about pricing, it could add some kind of profligate package to the options list. Have some ex-Porsche people design it, call it the Teutonic Splendor Package, slap a massive price on it, and count the money. People will buy it, and no one will ever have to say again, "But the interior..." That said, this test car's cabin had every feature I wanted. The gauge cluster was bright, crisp, and readable in every shade of daylight.

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 extends production cuts, affects Cadillacs, Camaro and Acadia

General Motors is extending production cuts at some of its North America factories due to a chip shortage that has roiled the global automotive industry, the U.S. carmaker said on Thursday. The move's impact has been baked into GM's prior forecast that the shortage could shave up to $2 billion off this year's profit. GM's Lansing Grand River assembly in Michigan will extend its downtime through the week of April 26. The plant makes Chevrolet Camaros and Cadillac CT4 and CT5 sedans. It has been out of action since March 15. GM's Spring Hill assembly in Tennessee will shut down for two weeks starting the week of April 12. The plant makes the Cadillac XT5, XT6 and GMC Acadia. The company said it has not taken downtime or reduced shifts at any of its more profitable full-size truck or full-size SUV plants due to the shortage. The news was first reported by CNBC.
