In his own words: Carlos Ghosn on why EVs rule

That's a nice little dig at hydrogen fuel cell technology, Mr. Ghosn. The Nissan chief, long a champion and heavy-duty investor of electric-vehicle technology, wrote an essay on his LinkedIn Influencer page on why EVs are the theoretical wave of the future. It's obviously not an unbiased opinion, but he makes his points clearly. Ghosn points out that "refueling" costs per mile for EVs are about 70 percent less than gasoline and more than 60 percent less than hybrids. He cites the rapidly growing network of plug-in vehicle charging stations that are eliminating "range anxiety" with at least some folks, and notes that the fastest growing US plug-in vehicle market is, of all places, Atlanta. Additionally, Ghosn, near the bottom of the post, says that a plug-in vehicle charging station can be deployed for as little as $2,000, while building a hydrogen station costs about $2.5 million. Pretty clever. Nissan's sales numbers appear to give Ghosn's confidence some clout. Through November, sales of the Leaf in the US surged 35 percent from a year earlier to more than 27,000 units. Globally, Nissan says the Leaf's sales are up 20 percent this year. Check out Ghosn's own words below. Zero-Emission Cars: Both Consumers and the Environment Win Last month, the Renault-Nissan Alliance sold its 200,000th zero-emission car. The Nissan LEAF, which we launched four years ago, is by far the top-selling electric vehicle worldwide. Sales are up 20 percent this year. Together with the Renault ZOE and other zero-emission vehicles in our lineup, Renault-Nissan's EVs have been driven about 4 billion kilometers – enough to circle the earth 100,000 times. They are the world's first and most successful mainstream, mass-marketed EVs. Why are more people switching to EVs? The reasons are clear: EVs are convenient: They can be refueled at home or at the office from multiple energy sources, including the increasing amount of clean energy from solar or wind power. Imagine never stopping at a gasoline service station because you wake up to a "full tank" every day. This is one of the top things EV owners enjoy about their cars. EVs are economical: Even with gasoline prices falling, Consumer Reports recently estimated operating costs of a Nissan LEAF in the United States at 3.5 cents a mile, compared with 11.9 cents for a subcompact gasoline car or 8.6 cents for a hybrid. EV owners typically save on their insurance policies, because insurers view EV drivers as a lower risk.

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 recalling 2012-14 Frontier pickups over fire risk

Nissan is recalling its Frontier pickup over fire concerns, according to a National Highway Traffic Safety Administration bulletin. A total of 13,535 vehicles are being recalled, all from the 2012 to 2014 model years, built between November 28, 2012 and December 27, 2013.
The NHTSA report states that "in the affected vehicles, a circuit breaker may have been installed incorrectly causing the main wire harness connected to the circuit breaker to face outward, potentially contacting a metal bolt located on the A-pillar." If this happens, it's possible that "the bolt may wear though the wire harness covering, resulting in an electrical short," NHTSA states. In the event of an electric short, a fire may occur.
The official recall will begin in March, where Nissan dealers will inspect the circuit breaker for the correct orientation, and if necessary, repair the vehicles, free of charge. Scroll down for the full NHTSA bulletin.
