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.

2014 BMW 328i xDrive Gran Turismo

"The Ultimate Driving Machine" has been BMW's tagline for nearly 40 years. Launched in the 1970s, the marketing campaign was a stroke of genius by ad firm Ammirati & Puris, as the phrase helped differentiate the imported Bavarian cars from their fellow European rivals by subtly pointing out that Mercedes-Benz and Audi were offering luxury models, while BMW was selling sporty and youthful driving dynamics. The campaign worked - some would argue that stands among the most effective ad campaigns ever - and countless Baby Boomers embraced the brand's fun-to-drive image by taking delivery of the company's new models.
BMW still boasts that its vehicles are "The Ultimate Driving Machine" four decades later, but the brand is very different today. It offered just a few model lines in the mid-1970s, and only a handful of vehicles within. In 2014, the automaker offers an exhaustive range comprised of nearly a dozen lines with almost 50 different models. To survive and thrive, BMW has decided it must massively broaden its appeal.
One of the latest arrivals to BMW's ever-growing stable is the 2014 3 Series Gran Turismo. The five-door hatchback is best thought of as a smaller version of the company's 5 Series Gran Turismo built on stretched 3 Series platform that, in the case of this test car, shares the running gear of the 328i xDrive sedan. On paper, the five-passenger vehicle checks all the proper boxes with regards to performance, utility and economy. But does this family-focused 3 Series still deliver driving dynamics that qualify it for the title of Ultimate Driving Machine?

Which of these five plug-ins should win the 2017 Green Car of the Year?

It's going to be a competitive race for the 2017 Green Car Of The Year. With a minivan in the running for the first time in ages, the five finalists announced by Green Car Journal today include five very different plug-in vehicles. As Ron Cogan, the editor and publisher of Green Car Journal, said in a statement, "electrification is now considered by most automakers an essential technology for current and future high-efficiency models." Let's check out the list: Toyota Prius Prime, the updated plug-in version of the world's best-selling hybrid. Chevy Bolt, GM's all-new entry into the long-range EV game. Chrysler Pacifica, a family hauler with the ability to go 30 miles on electric power. Kia Optima. The nomination is for the full line-up, but really the hybrid and plug-in hybrid models are the green stars here. BMW 330e iPerformance, one of the automaker's many new plug-in hybrids that bring battery power to models outside the i sub-brand. Green Car Journal will announce the winners at the Los Angeles Auto Show on November 17th, along with some, "other green transportation announcements," whatever that means. Last year, the winner was the 2016 Chevy Volt, the first model to snatch up two wins. Which do you think should win this year?
