BMW has the first smart emergency system for motorcycles

While cars and trucks have long had smart emergency systems to send help in the event of a crash (think services like OnStar), motorcycles have had to go without -- a scary thought if you've ever worried about wiping out miles away from help. That's where BMW might just save the day, though. It's introducing the first smart emergency tech for motorbikes, Intelligent Emergency Call, to give the two-wheel crowd a proper safety net. You can trigger it yourself, such as when you need to help a fellow motorist, but the real magic comes with its automatic responses. IEC's acceleration and lean angle sensors can not only tell if your bike falls or crashes, but time the call for help based on severity. A bad accident will call for help immediately, for instance, while a gentler incident provides a delay so that you can cancel the call. If things are dire enough for that call to go out, it'll send your ride's position at the same time. Don't expect to see this system in North America, at least not any time soon. IEC will first launch in Germany sometime in early 2017, and it'll spread to other European countries soon afterward. There's no mention of availability in other countries, unfortunately. However, you may well see equipment like this become widespread among bike makers eager to one-up the competition.Related Video: This article by Jon Fingas originally ran on Engadget, the definitive guide to this connected life.

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.

BMW joins the mirrorless car club at CES

Another item the future promised us is finally arriving: cameras for rearview mirrors. It's coming on the Cadillac CT6, Audi played around with the idea in its Le Mans racers, and Tesla has plans to get in on the action. And now add BMW to that list with the i8 Mirrorless concept revealed at the 2016 Consumer Electronics Show in Las Vegas. In BMW's scheme, three cameras replace the mirrors. One big adjustment from years of automotive convention is the lack of any side glances for the driver. A display in place of the conventional rearview mirror shows a composite wide-angle image. Imminent hazards, such as a vehicle in the blind spot, are shown with yellow warning icons. Previous mirrorless designs have mounted cameras flush with the body, but the i8 Mirrorless uses wing-like side cameras. They also serve as turn signal indicators. We assume that the narrow profile is more aerodynamic than the housing for a large piece of reflective glass. Also in BMW's CES bag of tricks is the BMW i3 Extended Rearview Mirror. This uses a rear-facing, roof-mounted camera that overlays images on the conventional interior mirror. But we do have some questions – what happens when the cameras get dirty? Mirrors still work even when partially obscured by dirt. And when will these ideas see production? Stay tuned as we'll follow up with answers from BMW's booth on the CES show floor soon.
