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.

2016 Technology of the Year Finalist: 2016 BMW 7 Series

BMW remade the legendary 7 Series around technology for 2016. Yes, the sixth generation of BMW's iconic flagship remains a luxury leader, but its sophisticated new features expand the 7's traditional strengths to a new generation that relies on smartphones. The 7 Series' extensive tech is most evident inside, where the driver and passengers have new interactions with the car. A feature called gesture control allows the driver to turn up the volume, accept or decline phone calls, or turn off the home screen using hand movements (see the video below). The sedan also has a digital instrument cluster, LCD touchscreen keyfob, wireless charging feature for phones, and a pinch-to-zoom function that makes iDrive simpler to use. Life is especially good in the backseat, where a seven-inch Touch Command Tablet allows the passenger to control comfort, lighting, and infotainment tasks. There's also WiFi, a gorgeous panoramic Sky Lounge LED roof, and 10-inch screens mounted into the seatbacks. Creature comforts and connectivity aside, BMW literally redid the 7 Series to the core. The new body structure, called Carbon Core, helps the sedan cut weight by up to 190 pounds compared with its predecessor while improving stiffness and rigidity. Meanwhile, the big sedan now offers four-wheel steering, improved aerodynamics, and it will get a plug-in hybrid version next year. It's still a 7 Series, and that means it has all of the luxury can you imagine. The car will massage you, perfume the air, and ionize the cabin. Naturally, it has a potent twin-turbo V8 pushing out 445 horsepower. This is what you've come to expect from BMW. But with the new 7 Series, the venerable automaker moves toward the modern tech-savvy consumer, and that's why Bavaria's most decadent sedan is a finalist for our Technology of the Year award.

Recharge Wrap-up: BMW, Nissan team up on chargers, CNN loves Tesla Model X

CNN Money calls the Tesla Model X "the new king of crossover SUVs." In its round-up of its favorite luxury SUVs of 2015, CNN places the electric ute on the top of its list. The Model X's EV powertrain, excellent acceleration and handling and cool design and technology features (including much attention paid to its slick Falcon Wing doors) earn it high praise. See the video above, and read more at CNN Money or from Clean Technica. Tesla has plans to open offices in Korea and South Africa. Tesla has registered in Korea as Tesla Korea Limited under co-CEOs Todd Maron (Tesla general council) and Susan Repo (Tesla Financial Services). It will have an office near Seoul. Tesla is also reportedly opening an office in South Africa in January, with GreenCape CEO Evan Rice acting as Business Development Manager. Rice will work to build a market for Tesla's PowerPack stationary energy storage systems. Read more from Korea Times, from htxt and from Teslarati. BMW and Nissan are partnering to build 120 new fast charging stations in the US. The public, 50-kW DC chargers, operating on the Greenlots charging network, will be deployed in 19 states in order to support Nissan Leaf and BMW i3 drivers, and to help promote EV adoption in the US. The chargers will support both CHAdeMO and SAE Combo charging. "Together with Nissan, we are focused on facilitating longer distance travel so that even more drivers will choose to experience the convenience of e-mobility for themselves," says BMW's Manager of Connected eMobility, Cliff Fietzek. Kia also recently partnered with Greenlots to provide charging for Soul EV drivers. Read more in the press release below.
