A conversation with GM's Mark Reuss on MPG, aluminum and Corvettes

There was plenty to talk about when General Motors hosted its annual mid-December holiday media reception a few months ago. GM had just decided to pull its global Chevrolet brand out of major European markets, where Chevys have competed directly with GM Europe Opel and Vauxhall vehicles, and the US government had sold its last remaining shares of GM stock. But most important was the company's just-reshuffled leadership. Post-bankruptcy CEO Dan Akerson had announced that he would step aside and that 52-year-old Mary Barra would replace him on January 15. Not only would she be the first woman to lead a major automaker, she would also be GM's first engineer CEO since Bob Stempel in the early 1990s. "I look at 2013 and 2014, as the retooling of General Motors" - Mark Reuss Replacing her as executive VP for global product development (and purchasing and supply chain) would be 49-year-old Mark Reuss, who had served a stellar four years as North American president, and elevated to corporate president (from executive VP and CFO) would be 42-year-old Dan Amman. All three are relatively young auto enthusiasts who are liked and respected inside and outside the company, and their collective talents and experience are highly complementary. I've interviewed Barra and found her smart, personable and knowledgeable, though she carefully walks the corporate line in speaking and answering questions. I met and chatted with Ammann for the first time at that holiday reception, and he made a good first impression. But I've known Reuss for some time as a genuinely good guy and a highly capable and inspiring leader, and I believe he is exactly the right person for the global product responsibility once famously held by the outspoken, oft-controversial Bob Lutz. So I jumped at an opportunity to join a group interview of Reuss (with mostly business reporters) at the Detroit Auto Show in January. It was an interesting session of mostly good questions, which he answered with refreshing candor and humor. "I look at 2013 and 2014, as the retooling of General Motors," Reuss said. "We've taken down almost every plant in North America, converted and turned it this last year, and to do that with award-winning vehicles and pretty flawless launches is key. We have to keep the train rolling on great product, because the rest won't happen without the best product, period." A reporter asked whether GM was pushing big trucks, SUVs and Corvettes again because gas is cheap. "No," Reuss said.

2016 Chevy Camaro takes a walk on the wild side at SEMA

From highly modified restomods to tuned pickups, Chevrolet has over 20 custom vehicles at this year's SEMA Show. Given the popularity of the Camaro in the aftermarket, it's no surprise that the new, sixth-generation model gets in on that act with four modified examples. Thanks to a combination of concept parts and components on the way in early 2016, Chevy gives future owners an idea of what's possible for their new coupe. Among the group are two takes on the SS trim at opposite ends of the color spectrum. The Chevrolet Performance version is Summit White with red accents, and it uses a lowered suspension to hunker the body over conceptual 20-inch wheels. Alternatively, the Camaro Black wears darkened trim, tinted glass, and matching 20-inch wheels. Chevy beefs up their performance to fit the added style by equipping both customs with exhaust, air intake, and brake upgrades. By far the weirdest among Chevy's group of modded Camaros is the Krypton concept in a custom shade of eye-popping green. This wild paint is electroluminescent, and when the system is activated, illuminated bowties appear across the body. Headlights with matching trim and painted exhaust tips finish off this alien aesthetic. Finally, the Camaro Hyper concept is for those looking for just a little added style for their coupe. Based on the LT trim with the 3.6-liter V6, it features Hyper Blue Metallic paint with white stripes and rides on 20-inch wheels. For a little added performance, coupe uses Chevy's aftermarket exhaust and a lowered suspension.

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.
