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-Toyota joint sports car project is on like Donkey Kong

It's official - there will be a jointly developed sports car from BMW and Toyota. While the two auto giants signed a Memorandum of Understanding that pledged to pursue "joint development of architecture and components for a future sports vehicle" back in June of 2012, in the interim, it has remained unclear how those plans had been progressing. BMW has finally officially confirmed that the German and Japanese manufacturers will be codeveloping a pair of sports cars in addition to pursuing other disciplines including fuel cell systems and lightweight technologies.
"We have agreed on a joint architecture for a sports car. What is important is that there will be two different vehicles that are authentic to the two brands," BMW Development Chief Herbert Diess told Germany's Frankfurter Allgemeine Zeitung, Reuters is reporting. This is a very, very big step for both brands, but now the speculation can officially begin as to what the products of this agreement will look like.
There's ample reason to believe that the BMW-Toyota tie up will result in a Supra successor based on comments made by the chief engineer of the GT86/FR-S program, Tatsuya Tada, back in August. Follow that with a rumor from earlier this month that Toyota could debut a Supra concept car at the upcoming Detroit Auto Show later this month, and we could be seeing the fruits of this partnership sooner rather than later.

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.
