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.

Autoblog Minute: New Civic, FCA UAW Agreement, Frankfurt

FCA reaches a tentative agreement with the UAW, Honda reveals the all-new 2016 Civic, and the Frankfurt Motor Show dazzles us again. Autoblog senior editor Greg Migliore reports on the Weekly Recap edition of Autoblog Minute. Show full video transcript text [00:00:00] FCA reaches a tentative agreement with the UAW, Honda reveals the all-new 2016 Civic, and the Frankfurt Motor Show dazzles us again. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. FCA reached a tentative labor agreement with UAW leadership. The major focus of the new deal reportedly includes: the eventual elimination of the two-tier pay scale [00:00:30] and pooling worker health care. Now that a leadership agreement is in place, the deal will be sent to FCA's rank-and-file. FCA has about 36,000 hourly employees. We got a first look at the interior and exterior of the 10th-generation Civic. Honda expects the new sedan to dominate the C-segment when it hits dealerships later this fall. Civic coupe, five-door hatchback, Si and Type R will all come later. The 2015 Frankfurt Motor Show is in the books and there was a lot of news to get excited about. [00:01:00] Porsche introduced a fully electric concept car in the Mission E. If they make this car, Porsche could give Tesla nightmares. We also saw SUVs from Jaguar and Bentley. There were two beautiful Italian convertibles from Ferrari and Lamborghini. Meanwhile, Mercedes introduced a concept of their own in the IAA - a vehicle that experiments with adaptable aerodynamics. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. Plus we'll have some added insight on General Motors' deal to [00:01:30] avoid federal prosecution.

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.
