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 sold 2.49 million BMW, Mini and Rolls-Royce vehicles in 2018

FRANKFURT — German carmaker BMW on Tuesday said it achieved record sales of 2.49 million BMW, Mini and Rolls-Royce vehicles last year. "BMW Group achieved record sales in 2018. 2.49 million vehicles mean the BMW Group is the world's leading premium automotive company for the 15th year running," Chief Executive Harald Krueger said. In 2017, BMW Group sold 2.46 million vehicles. Daimler has not yet released annual sales figures for Mercedes-Benz passenger cars, so it remains unclear whether BMW brand overtook Mercedes-Benz in terms of sales in 2018. Sales of BMW, Mini and Rolls-Royce cars were higher than Mercedes-Benz in 2017.

Park your BMW with a wave, 3D instrument clusters, and more

Remote parking your car with a smartphone app is so 2015. In the future envisioned by BMW, you can park your car by giving it hand gestures. Meanwhile, the car will sync with your smart home and display traffic information on your hallway mirror. It's all part of a giant list of concepts and technologies BMW is bringing to the 2016 Consumer Electronics Show. Let's break down some of the big ideas BMW's bringing to this year's CES. Park By Waving Actually, you don't even need to wave to get this i3 Concept to start moving. From inside your house, simply picking up the key can signal your connected garage door to open and tell your car to pull out into the driveway. Out in the wider world this concept takes automated parking a step further than current in-car parking assistance systems. Once a spot is found, the driver gets out and waves at the car. The i3 then does all the movement on its own. What's the benefit of watching your car park instead of sitting inside while it parks itself? Not much, other that the ability to fit into narrow parking spaces. But I'm a sucker for automation like this, as long as it works better than those infernal foot-kick tailgate opening systems. The Bumper That Snitches For You If you have a car already covered in cameras, why not use them for more than parking? Bumper Detect is BMW's take on the valet-mode recording in the Chevrolet Corvette. But instead of filming any motion, BMW's system monitors the body and bumpers for any unexpected impacts and immediately captures the footage. An alert goes to the driver's smartphone via the BMW Connected App, with available live streaming images. Samsung Smart Things And The Smart Home The i3 on display at CES intergrates Samsung's Smart Things app into the iDrive controller. This allow you to use connected smart home features inside the car, like turning off lights or adjusting the thermostat. BMW's vision further into future integrates the car into the home even more with what the automaker calls Open Mobility Cloud. You can call it a personal assistant or an evil digital spy, depending on your perspective of this kind on technology. In any case, Open Mobility Cloud uses predictive algorithms to plan the day and give relevent information through BMW's smartphone app or – in a super futuristic way – a Mobility Mirror inside the house.
