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.

Mitsubishi, Nissan will build mini EV together

That minicar project that erstwhile competitors Nissan and Mitsubishi launched about four years ago is about to go a little more maxi. NMKV Co., the joint venture established in June 2011 by the two Japanese automakers to make minicars, is going to get more resources specifically to ease a move into the electric-vehicle sector. Specifically, Nissan, which makes the all-electric Leaf, is going to have a bigger role in the testing, design, and development of the partnership's mini EVs. A memorandum of understand between Nissan and Mitsubishi, maker of the i-MiEV, is in the works. So far, the joint-venture has sold about 500,000 gas-powered three-cylinder compact vehicles under the two automotive brands, so it must be doing something right. The first Nissan Dayz and the Mitsubishi eK Wagon models started production in 2013. Sales of the Nissan Dayz Roox and Mitsubishi eK Space, which went the higher-roof route, began early last year. Nissan and Mitsubishi started making noise about this last summer, when word came out that the little EV may be priced at less than $15,000 in Japan, quite a bit cheaper than either the Leaf or the i-MiEV over there. As with the current models, the future minicar variants will be produced at Mitsubishi's Mizushima factory in Japan. So far, the partnership would only say that details about NMKV's next-generation mini EV will be released "at a later time," so specifics like range and other performance measures will have to wait. Until then, you can take a look at NMKV's press release below. Nissan, Mitsubishi Motors and NMKV reach agreement on planning and development of next-generation minicars Nissan Motor Co., Ltd., Mitsubishi Motors Corporation, and their joint venture NMKV Co., Ltd. today reached an agreement to continue their joint project regarding development of the next generation of current minicar models. The three companies will soon sign a memorandum of understanding. The companies aim to develop more competitive products by optimizing resource allocation and their respective roles and responsibilities. Nissan will be more deeply involved in development operations, such as design development and testing. In addition to its product planning and project development roles, NMKV will strengthen its management capabilities by adding a new department to enhance collaboration with engineering and manufacturing functions. Vehicle production is planned to continue at Mitsubishi's Mizushima Plant.
