2014 Nissan Dayz Roox is the littlest high-roof van you ever did see

Even average production cars from Japan often seem very conceptual to US eyes. Throw in typical, nonsensical-quasi-English-words name like "Dayz Roox" and you'd be forgiven for thinking this Nissan box on wheels was still a designer's dream. But the fact is that the Nissan Dayz is a model currently on sale, and this Roox version is the latest take on the micro-van, which is a popular segment in Japan.
In fact, this generation of Dayz is the first minicar that Nissan has developed completely in-house, and the thing has been selling astoundingly well in its first stint on the market (30k units in month one month, says Nissan). So it's unsurprising that the company is looking to expand the range with a model that is more fully featured.
The Roox (we have no clue as to where that name came from, or what it means) would appear to be a high-roof version of the three-cylinder Dayz minicar - in fact Nissan goes so far as to call it an "Impressive Super Height Wagon." Features like automatic sliding doors, Around View Monitor and UV-insulated glass are all luxuries in kei-class car. The press release also specifies that the Roox is tall enough to swallow a 27-inch bicycle.

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.

Nissan's plan to supply US Mitsubishi dealers with family sedan stalls

Mitsubishi has quietly had some big success recently. The Japanese brand sold 77,643 vehicles in the US for all of 2014, a 24.8 percent jump over 2013. While still relatively small overall (Ford sold 74,355 F-Series trucks just in December, for example), it shows definite growth for the sometimes forgotten automaker. Unfortunately, the latest news might not help the company's future expansion. The proposed partnership of Mitsubishi and the Renault-Nissan Alliance on at least one midsize sedan for the US market is off the table, according to Automotive News. The company informed sellers that the collaboration had fallen through during a National Automobile Dealers Association meeting. "I told them that the plan has stalled," said Don Swearingen, executive vice president of Mitsubishi Motors North America, to Automotive News. "And I said that's really all I can tell you at this time." Under the original partnership, Mitsubishi was supposed to get a D-segment sedan that would have been built at the Renault-Samsung factory in Busan, South Korea. The automakers were also negotiating for Mitsu to get a C-segment four-door as a global model and developing an electric kei car for Japan together, due in 2016. While the sedan is gone, Mitsubishi isn't completely bereft of improved products in the pipeline. The Mirage Sedan is being launched in the US, and the Outlander is supposed to get a redesign for the 2016 model year. According to Automotive News, the Outlander Sport and Lancer are also due for refreshes in 2016, and a new Mirage is on the way.
