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.

24 Hours of Le Mans live update part one

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice with a profanity-laden stream-of-consciousness writing style. Parker lives in Hawaii and spends far more time spearfishing than behind the wheel of a car. Jump ahead to Part Two here, and Part Three here. Big Money and billionaire hobbyists and rockets on wheels. Jets belching French color smoke overhead. Balance of power fuckery. Plenty of water on the ground this morning. Absurdly expensive motorcars lined up in the pissing rain. Fast twitch lunatics behind the wheel. Chomping at the bit. Let's go let's go let's go! Race hasn't even started, Ford #67 maybe dealing with clutch issues. Karma? That beautiful bastard Brad Pitt's out on the track, waving the tricolor flag. It's a standing start in "Noah's Ark" weather and the 2016 24 hours of Le Mans is go! First lap takes place behind the safety car, finished in a record setting 8 minutes 27 seconds. Wrong kind of record maybe, but this is the first time I've set my mind to watching the whole damn race. Feel like I'm part of history. 3:00 AM on Kauai, a little too early for life. Sucking down coffee like a maniac. Don't fall back asleep. Got my hands on four hours of rest, how much more can I need? Better be enough for the next twenty four hours. Gonna get kinda punchy toward the end. Jason Statham on the scene. Four feet of solid muscle, non-existent hairline. Lovely wife peanut gallery sitting next to me calls him the "best race car drive in the world." Not sure if she's serious. Toss up, could go either way. Statham's a funny guy. Heir to the Bruce Willis comedy action crown. Really good in the movie where the fat comedy lady plays a spy. Ford's on the road. Problems with gearbox pressure, apparently. Nearing a half hour in and the safety car is still on the track. Hellish amounts of water on the ground, in the air. Visibility is garbage. Getting better. Twitter wags, "Not with a bang but a whimper." Just building suspense. Mother Nature felt like killing some people today, race officials need to dial back the drivers until it dries a tad. Normal inclination would've seen 'em flying, guaranteed early lap wrecks. Sad news for that bloodthirsty part of my lizard brain I try and keep suppressed. Good news for humanity. #12 in the pit for a bit.

Corvette + fireworks = so much glory

You might think that those of us making our living by reviewing cars, think critically about the cars we're driving most of the time. It could be that I'm an underachiever, but that's not the case with me. In fact, unless I'm set to the review task, I typically think about the cars in front of and around me more frequently. That's because a) you never know what you're going to see out there, and b) all of them could be out to bump/scratch/tailgate/crash me out. You can never be too careful. Such was the case when I was driving a 2015 Chevy Corvette earlier this week. I'd already had my fun finding the edges of grip on a river road in the car, the night before; on the morning in question I was just trying to get to work. But while scanning the suburban streets for potential dangers to the 'Vette's neat-o Daytona Sunrise orange paint, I spied a XXL-sized fireworks tent in an empty parking lot. Oh right, I remembered, 4th of July weekend. That obvious bit of observation lead to a chain of thought along these lines: "We should do something with this car for the 4th" ... "Too bad I have to give it back tomorrow." ... "Wonder if I could do a quick video?" ... "Wonder if I can set off a bunch of fireworks in slow-mo for a video?" The result, well, I won't call it genius, but I will say that I remember why every kid loves fireworks. And I will call it glorious. Happy 4th, y'all.
