Is Buick's surprise Detroit concept a Camaro-sized coupe?

Tomorrow night marks the unofficial start of the 2016 Detroit Auto Show. Keep your eyes peeled for a number of reveals, including a surprise debut from Buick. Yes, Buick. And we think it's going to be something really hot. According to a report from Bloomberg, the Tri-Shield's secret car could be a Camaro-sized sport coupe concept. As Bloomberg explains, it'd certainly gel with the impression the company is trying to put out – that it's no longer a brand for those with one foot in the grave. Introducing a sports coupe, even as a concept, could certainly reinforce that message. And if it happens to make production – which is not a certainty, Bloomberg's secret source says – it could certainly help Buick drive its average buyer age down from 59. Bloomberg doesn't offer any speculation on Buick's new coupe, but we have no problem making educated guesses. Our most reliable conjecture is this: it will ride on General Motors' Alpha platform, which underpins both the Camaro and the Cadillac ATS. And with a certain twin-turbocharged V6 in the GM stable, we've got an idea of what kind of engine could be shown. That speculation will have to suffice for now. But don't worry, we'll have official details, live images, and video tomorrow when Buick unveils its new concept in Detroit's Eastern Market.

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.

Jeff Gordon to pace Indy 500 in Corvette Z06

The Chevrolet Corvette has served as pace car for the Indianapolis 500 more than any other vehicle in the century-long history of the race. And this year it'll be at the front of the pack again in the form of the Corvette Z06 driven by Jeff Gordon. With 650 horsepower on tap, the Z06 is among the fastest, most powerful cars ever to serve as pace car for the Greatest Spectacle in Racing – right up there, at any rate, with the ZR1 that led the field in 2012 and the Viper GTS from 1996. For this year's race, it's been decked out in white with special graphics, strobe lights and a red interior. The 99th running of the race will mark the 13th time a Corvette has been tapped for the honor. Gordon, a name better known to NASCAR fans, but certainly no stranger to the track, will handle driving duties. The four-time Sprint Cup champion has won the Brickyard 400 no less than five times, including the very first time it was held back in '94. No driver has won at Indy more than Gordon – a record he shares with Michael Schumacher, who won the US Grand Prix there five times. (AJ Foyt, Al Unser and Rick Mears share the record for Indy 500 victories at four apiece, in case you were wondering.) It'll be a busy Sunday for Gordon, who will also be competing in the Coca-Cola 600 at Charlotte on the same day. Jeff Gordon to Drive Corvette Z06 Indy 500 Pace Car Five-time Brickyard winner will lead pack for 99th running of the Indianapolis 500 2015-04-29 INDIANAPOLIS – Five-time Brickyard 400 winner and four-time NASCAR Sprint Cup champion Jeff Gordon will drive a Corvette Z06 pace car for the 99th running of the Indianapolis 500 mile race, May 24 at the Indianapolis Motor Speedway. It is the 13th time a Corvette has served as the official pace car, dating to 1978, and the 26th time a Chevrolet has led the pack for "The Greatest Spectacle in Racing." Corvette has served as the pace car more than any other vehicle in the race's history. Gordon, who grew up in nearby Pittsboro, Ind., is no stranger to the Indianapolis Motor Speedway. In 1994 he won the inaugural Brickyard 400 – the first-ever NASCAR race at the Brickyard, and has visited the winner's circle there four more times. That makes him one of only two five-time winners at Indy in any series. Michael Schumacher won five Formula One races there. "It's great to have Jeff Gordon serve as this year's pace car driver," said Jim Campbell, Chevrolet U.S. vice president of performance vehicles and motorsports.
