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.

Japan minister launches counterattack after Ghosn blasts justice system

TOKYO — Japan's justice minister launched a rare and forceful public takedown of auto executive-turned-fugitive Carlos Ghosn after he blasted the country's legal system as allowing him "zero chance" of a fair trial as he sought to justify his escape to Beirut. After his dramatic flight to Lebanon last month, Ghosn spoke in public for the first time on Wednesday, saying he had been treated "brutally" by Tokyo prosecutors. He said they questioned him for up to eight hours a day without a lawyer present and tried to extract a confession out of him. In an effort to undo Ghosn's attempt to sway public opinion in his favor, Justice Minister Masako Mori followed shortly with a statement, translated into English and French, and held a news conference after midnight and again around 9:30 a.m. on Thursday morning to defend Japan's justice system. "I decided to do this because defendant Ghosn was looking to justify his unlawful exit from Japan by propagating a false recognition of our justice system," she said at the second news conference. "I felt that we needed to respond immediately to broadcast a correct understanding to people around the world." Ghosn, the former chief of Nissan and Renault, fled Japan last month as he was awaiting trial on charges of under-reporting earnings, breach of trust, and misappropriation of company funds, all of which he denies. Mori said Ghosn's escape from his trial in itself "could constitute a crime" that would not be tolerated in any country. "My impression in listening to him was that there were few statements that were backed by any real evidence," she said. "If he wants to prove his innocence, he should face fair trial proceedings here," she added, stressing that the allegations against him concerned financial crimes in Japan. "That would be the mark of a first-class businessperson and good citizen." Mori blasted Ghosn for violating his bail by fleeing the country "without showing a passport and breaking international rules that everyone in the world follows." "It was a breach of faith that can't be explained to our children," she said. The spotlight on Japan's justice system comes as Mori is set to host in April the United Nations' Congress on Crime Prevention and Criminal Justice, held once every five years.
