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.

Bryant Gumbel and Katie Couric equate BMW i3 with the Internet

BMW fancies its new i3 electric car as something revolutionary – which, to be entirely honest, it is. But while we as automotive enthusiasts might know this, the general populous may not, which is why the German company is shelling out what is no doubt a substantial sum of money for a spot during this year's Super Bowl. Starring former Today Show hosts Katie Couric and Bryant Gumbel, the spot, called Newfangled Idea, focuses on another arguably misunderstood technology – the Internet. Starting with a now-humorous segment from 1994 that sees the pair discussing the then-new idea of the Internet – what does "@" mean? – Katie and Bryant then find themselves in an i3, asking very similar questions. Take a look at the video, up top, and then scroll below for the outtakes and a short behind-the-scenes segment from the clip. Related Video:

BMW preparing two concepts for Villa d'Este

Every spring, the finest automobiles ever to grace tarmac gather on the shores of Lake Como for the Concorso d'Eleganza Villa d'Este. It's a chance for the most beautiful classics to compete for awards and for automakers and design studios to show off their concept cars under the soft light of the Italian sun. But while most of the vehicles old and new that show up for the concours are ones we've seen before, BMW takes things a step further.
As patron of the concorso d'eleganza for the past ten years, BMW regularly cooks up something new for the glamorous extravaganza. Last year it teamed up with Pininfarina for the Gran Lusso Coupé and revealed it alongside the Concept 90 motorcycle. The year before that came the BMW Zagato Coupe, preceded by the 328 Hommage and the M1 Hommage (pictured above) before it.
The theme for this year's event is the Roaring Twenties. BMW may not have been known back then on the same level as Bugatti or Duesenberg, but Rolls-Royce sure was.
