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.

2015 Nissan Micra

Several years ago, poutine started showing up on the menus of a number of Detroit-area restaurants. For those unfamiliar with the Canadian specialty, it involves serving up french fries, gravy and cheese curds all in one artery-clogging heap. It's not really my thing, but the comfort-food dish has caught hold here in The D, and many absolutely swear by it. In a country where we happily serve Double Down sandwiches, and where competitive eating qualifies as sport, it's hard to believe le poutine isn't spreading like wildfire.
Given Detroit's proximity to Canada, it's not surprising that this culinary creation has managed to find its way across the border. The same thing goes for cars - we Detroiters are routinely privy to lots of Great White North imports. No, we can't buy not-for-US vehicles like the Nissan X-Trail, Mercedes-Benz B-Class (at least, the gasoline version), or now-discontinued products like the Honda Civic-based Acura CSX or EL before it. But Ontario-plated examples of these cars can be seen all the time here in southeast Michigan - it's a far more common occurrence than you might think.
These days, it's rare that an automaker will introduce a model to Canada without offering it up in the United States - especially a car that stands to do big things for a company's presence in North America. But with this 2015 Nissan Micra, that's exactly what's happened; Nissan's US arm has repeatedly stated that there are no plans to offer the car in Yankeeland. Why is the Micra so important? This five-door hatchback enters Canada with the coveted title of being the most affordable new car in the country: just $9,998 Canadian (CAD) to start. In fact, the Micra launches to our north just as the larger, four-door Versa Sedan is phased out in Canada - a vehicle that holds the lowest-cost title here in the US, at $11,990 USD.

Recharge Wrap-up: Nissan 'No Charge' in Denver, A123 doubles

Nissan has introduced its "No Charge To Charge" program in Denver, Colorado. As of June 2, customers who buy their new Nissan Leaf from certified dealers in the metro Denver area will get two years of free charging. Denver is the 16th market to offer "No Charge To Charge," with a total of at least 25 US markets scheduled to offer the program by the end of the year. "EV charging infrastructure continues to grow in Denver," says Nissan EV Sales and Marketing Director Andrew Speaker, "and access to free public charging for new Leaf buyers helps make owning an all-electric vehicle even more cost-effective and convenient."

The combined capacity of its three production facilities in Michigan, Hangzhou, China and Changzhou, China will increase from 750 megawatt-hours to 1.5 gigawatt-hours in the next three years. The increased capacity will help support customers building hybrids, passenger EVs, and commercial vehicles. Included in the expansion is the capacity to build 12-volt starter batteries and 48-volt microhybrid systems. "It's been a tremendous turnaround," says A123 CEO Jason Forcier, referring to the company's 2012 bankruptcy. Forcier also says the company is already planning another expansion when this one is complete. Read more at Automotive News, and in the press release from A123. The Royal Hashemite Court of Jordan is ordering 150 Zoe EVs from Renault. King Abdullah II of Jordan signed an agreement with Renault, who will deliver the cars by the end of the year. The cars will be powered completely by solar energy generated on royal property. The order of the 150 Zoes is the largest since 2013, and makes Renault the largest provider for Jordan's royal EV fleet. Renault says that further EV orders are already being discussed.

Current policy, designed to help alleviate traffic and air pollution, restricts cars with even and odd license plates from rush hour traffic on alternating days. The exemption for EVs runs from June 1, 2015 until April 10, 2016. It is the newest in the list of perks meant to encourage EV adoption, despite the troublesome lack of charging infrastructure.
