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 touts e-NV200 as electric VIP transport

While the big auto show may be in Paris next month, right now in Hannover, Germany, commercial vehicle manufacturers are peddling their wares to fleet operators. Among them is Nissan, which is not only upgrading its NV400 full-size van with new engines and technology, but also showcasing a rather unusual show car in the form of the e-NV200 VIP Concept. Nissan has outfitted this electric NV200 demonstrator to chauffeur passengers around town in comfort and under electric propulsion. It's decked out in a two-tone metallic blue paint job and an interior upholstered in white leather contrasting with black trim and carpets, although for some reason the Japanese automaker hasn't seen fit to release any interior images. In the back you'll find a 21.5-inch DSP monitor, LED lighting and a pair of "club class" seats (again, no pictures), moved aft-wards to maximize leg room to 26 inches with an extendable footrest, while still allowing for luggage space behind. The driver can even make use of Nissan's new Smart Rear-View mirror to help get passengers as close to the red carpet as possible. NISSAN SHOWCASES EV FOR VIPs Zero emission e-NV200 is transformed for ultimate comfort city transport -introducing the e-NV200 concept for VIPs. - Luxuriously appointed 100% electric for downtown VIP passenger shuttle - Two-tone metallic blue exterior and white leather seats - Limousine-like space and 21.5-inch monitor with digital device connectivity - Smart Rear-View mirror providing clear rearward visibility in all conditions Hannover, Germany (23rd September, 2014) Fresh from launching the game-changing 100% electric Nissan e-NV200 compact van, the world's leading electric vehicle manufacturer has created a new zero emission concept for VIP transportation - the Nissan e-NV200 VIP Concept. Designers have upgraded the all-electric e-NV200 Evalia people carrier into a zero emission van perfect as shuttle transport for VIPs. The benefit of being zero emission means that the van can access all current and future clean air zones, as well as drive inside buildings, for the ultimate in discreet convenience. Behind the spectacular two-tone exterior lies a sophisticated and luxurious interior. The seats are covered in premium quality white leather with blue accents, which contrast with the predominantly black lower portion of the cabin - the trim and carpets are black with a piano black finish on the control surfaces.

Why a Renault-FCA merger could be good news for Nissan, Mitsubishi

TOKYO — Nissan's advanced technologies including platforms and electric powertrains could give it leverage in a merger involving Renault and Fiat Chrysler, thanks to a royalty system it has with the former, two people with knowledge of the matter said. A merged Renault-Fiat Chrysler could face an extra hurdle each time it uses technology developed by Nissan or Mitsubishi Motors, while the two Japanese automakers stand to gain a client in Fiat Chrysler (FCA), one of the people said. Both sources declined to be identified because of the sensitivity of the matter. Nissan's technology, particularly in electrification and emissions reduction, could give it some sway in the $35 billion potential tie-up between Renault and FCA, even as its stake in the newly formed company would be diluted. Currently Renault SA pays less for technology developed by Nissan than the Japanese automaker pays for French technology, a third person said. This has long been a sticking point for Nissan, and an area where Nissan could seek more favorable terms. "Whenever Nissan transfers platform, powertrain or other technology to Renault, there is a margin or royalty which Renault has to pay for use of that tech," one of the people said. "In that sense, FCA, if everything went well, would become another 'client' of ours and that's good. More business for us." A Nissan spokesman declined to comment on its royalty system. The potential Renault-FCA deal has complicated the Japanese automaker's already uneasy alliance with Renault. A further deal with Fiat Chrysler looks likely at least in the near term to weaken Nissan's influence in the 20-year-old partnership. Renault owns a 43.4% stake in Nissan and is its top shareholder. Nissan holds a 15% non-voting stake in Renault and would see that diluted to 7.5% after the FCA deal, albeit with voting rights. The imbalance between the two has long rankled Nissan, which is by far the larger company. Alliance imbalance Renault had previously angled for a merger with Nissan but has been rebuffed by CEO Hiroto Saikawa. Securing benefits from the merger deal will be important for Saikawa, who is grappling with poor financial performance while he struggles to right the company after the ouster of former chairman Carlos Ghosn last year.
