Nissan NV400 becomes Japan's first electric ambulance

Consumer passenger cars aren't the only vehicles undergoing electric transformations. We've seen the introduction of early electric fire trucks, and now Japan is getting its first electric ambulance. It's a Nissan NV400, and it will be used by the Tokyo Fire Department at the Ikebukuro station. Though badged as a Nissan, the NV400 is at its heart a Renault Master Z.E. electric van. The powertrain is the same as the French van with a 33-kilowatt-hour battery (7 kWhs less than the base Nissan Leaf) and a 55-kW motor driving the front wheels. That translates to 74 horsepower and 162 pound-feet of torque. That doesn't sound like much, but in as dense a city as Tokyo, it's not likely the NV400 will be able to reach high speeds at all, even if it had a Hellcat engine. There are a couple of unique additions to the van to enhance its ambulance capability. One is the inclusion of a separate 8-kWh lithium-ion battery that can operate all the equipment on board for long periods of time without eating into the ambulance's range. It can even be used like a generator to provide power to external emergency equipment. Then there's the stretcher, which Nissan vaguely says is electrified to make it easier to use by the medical personnel. We presume the stretcher has an electric motor to make it easier to push around. Since neither the NV400 nor its Renault counterpart is sold here, we're not expecting to see one of these ambulances in the U.S. any time soon. But electric versions of local emergency vehicles seem like a good idea, since range wouldn't be an issue, and the torque would be useful in large vehicles. Ford is readying an electric full-size Transit, which is offered in America in gas versions. Perhaps we could see some electric Ford ambulances in the near future. Related Video:

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 Bladeglider now on the backburner

There have been some big shakeups within Nissan's top executive ranks in the past 12 months, including Johan de Nyscchen leaving Infiniti to run Cadillac and Andy Palmer taking over Aston Martin. With them gone, the automaker's future product portfolio looks to be shifting as well. Among them, the chances are dwindling for the BladeGlider to actually arrive in dealers – already a rumored possibility. New Nissan planning boss Philippe Klein isn't nearly as hot on the idea of the BladeGlider as his predecessors. Where Palmer said last year the vehicle was in the brand's mid-term plan, Klein recently told Autocar that the model was "not among the immediate priorities." He didn't slam the door entirely on potential production, though. "It is still on the table, but at the end of the day it has to make sense to the company." Debuting at the 2013 Tokyo Motor Show, the BladeGlider translated the narrow-front, wide-rear wedge shape of the Deltawing and ZEOD RC racers to the street. In concept form, it used an electric drivetrain with hub-mounted motors, and the driver sat in the center with two passengers flanking them to the rear. According to Autocar, the project to develop a production version got at least as far as creating test cars from Ariel Atoms. The BladeGlider's renegade styling hasn't been the only thing holding it back from seeing the road, though. Panoz has a pending lawsuit against Nissan that claims the styling for the Nissan ZEOD RC and the BladeGlider infringe on the intellectual property for the Deltawing's design.
