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.

The Rinspeed Etos is a BMW i8 that drives itself and comes with a drone

Outlandish as they can be, we've grown accustomed to seeing Rinspeed unveil its avant-garde concept cars at the Geneva show every year. But this time the Swiss studio will present its latest showpiece outside of its native country, taking the veil off at CES in Las Vegas. It's called the Etos, and takes the advanced concept of the BMW i8 even further. Frank M. Rinderknecht and company designed the Etos around autonomous technology. Now if you're wondering why anyone would need a self-driving sports car, we're with you. But if Rinspeed is out to capture our attention, the svelte shape, eye-catching yellow paint, and 20-inch Borbet alloys have certainly done that much. Recognizing the transformation possible in the cabin of a self-driving automobile, Rinspeed fitted the Etos with a retractable steering wheel. That allows unfettered access to a pair of 21.5-inch ultra-HD widescreen displays hooked up to a connected infotainment system that learns from the driver's (or occupant's) habits to minimize the necessity to manually input information. No less than eight exterior cameras work in conjunction to all but completely eliminate the notion of the blindspot. But like so many mullets festooning the streets of Las Vegas and the slopes of the Swiss Alps alike, the party trick is found around back. Not unlike a megayacht with a helipad, Rinspeed fitted a remote-control helicopter on the rear deck that can be used for anything from selfies on the go to retrieving packages along the driving route. The drone lands on a platform with 12,000 individually controlled LEDs and covered in Gorilla Glass furnished, as with the glass roof, by Corning. Combine the drone with the ability to pay tolls and other charges through NFC signal while charging your phone inductively, and the driver/occupant may never need to get out of the car unless he or she wants to (and the singularity controlling all these systems permits). Fortunately Rinspeed made the interior a comfortable place to be, filled with niceties and distractions from a watch winder on the dashboard to the ceramic and titanium trim to the San Francisco skyline stitched, for some reason, into the seatbacks. Few of these features strike us as strictly necessary, and the most outlandish of them (we're looking at you, drone) will likely never be implemented on a production automobile. And what features do will likely find their home in more accommodating vehicles than a two-seat sports car.

BMW says yes to 1 Series M successor, no to M6 Gran Coupe with xDrive

If you're anything like us, the first half of that headline made you smile. The BMW 1 Series M Coupe was, without a doubt, one of our favorite cars from the past few years, and according to a BMW Blog interview, Dr. Friedrich Nitschke, head of the company's M division, has confirmed that a successor is in the works.
"We haven't made a decision yet, but the 1M coupe was so successful, that in my opinion, I am absolutely sure we will build a successor," Nitschke told BMW Blog. Currently, BMW only offers the M135i version of the new 1 Series hatch in Europe, which Nitschke says is "not a pure M car."
Moving elsewhere in the M range, BMW Blog asked about the M6 Gran Coupe that recently debuted at this year's Detroit Auto Show. The obvious competitors for this car will be higher-power versions of the Porsche Panamera and Audi RS7, but while both of those offer all-wheel drive, the M6 only sends power to its rear wheels.
