Experience the New York Auto Show by drone

The Autoblog team recently returned from wildly running around the Javits Center to cover all the news and debuts at the New York Auto Show. Sometimes, it's nice to take a more serene look at the exhibition floor, though, and the event's organizers are providing that exact opportunity by flying a drone through the hall. Combined with the down-tempo music, this clip feels like a form of automotive meditation. If you're going to miss the show in the Big Apple, the drone also provides a good overview at the exhibition floor, especially at the stands from Lexus, Buick, Dodge, Mercedes-Benz, Toyota and BMW. Plus, it's a fun way to see some vehicles from a completely different angle than they ever appear on the road.

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.

Hamann M6 Gran Coupe is all flared and shiny

Oh, Hamann. After rolling out the ridiculously pink Mystère at this year's Geneva Motor Show, the tuning company has worked its mirror-finishing magic on the BMW M6 Gran Coupe, debuting this, the aptly named "Mirror" at the Frankfurt Motor Show. It sure is shiny, and a full 40 millimeters wider than the standard M6 GC.
Hamann says that the, um, "tailor-made suit" exterior treatment is made up of a new front bumper spoiler with large air intakes, side skirts, a new rear spoiler, and wing extensions out back. And the end result is... well, let's just call it noticeable. The special BMW rides on unique 21-inch wheels and sits a full 25 millimeters closer to the ground, as well.
As far as we can tell, Hamann hasn't upgraded the M6's 4.4-liter twin-turbo V8 at all, though there's a new sport exhaust system that "depending on the application area, either noisily announce its presence or purr sportily." Sounds like it's as loud as its newfound appearance.
