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, Mini to offer Amazon Alexa in all models beginning next year

Voice recognition has been available in cars for years now, but the technology has improved, and found its way into our pockets and our homes. With applications like Siri and gadgets like the Amazon Echo essentially acting as digital personal assistants, the ways we interact with technology through our voice have advanced significantly in recent years. BMW plans to take advantage of the evolved voice technology, and will offer Amazon Alexa in every BMW and Mini model beginning in the middle of 2018. Drivers will be able to use the usual Alexa features (or "skills" in Amazon speak) to get the latest news and weather, provide entertainment, or remotely control their smart home gadgets. Alexa will also perform car-specific duties, such as navigation or locating nearby businesses. Users can also check on movie times, request specific playlists or even order products from Amazon through Alexa. View 5 Photos It's the logical next step for BMW, which has allowed owners to check the status or control features of their car through Alexa's BMW Connected skill since last year. Users won't need to bring their smartphone along for the Alexa to work, as BMW and Mini models will be equipped with their own SIM cards. Alexa will be available in cars in the United States, United Kingdom and Germany. As our friends at Engadget point out, the timing is important, as Amazon risked being left behind by the likes of Apple and Google, which offer their technology in vehicles via Apple CarPlay and Android Auto. Amazon would do well to expand access beyond the three markets in-car Alexa will launch in, for exactly the same reason. Check out the video above for how BMW envisions users interacting with Alexa. We really hope some lucky M4 owner does, in fact, actually order a pizza while drifting on the deck of an aircraft carrier. That's a future we want to live in.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.
