Nissan prices replacement Leaf battery at $5,500

The battery pack is the single most expensive component in a plug-in vehicle and, until now, figuring out the cost to replace one has been a bit of a mystery. Last year, Nissan tried a $100/month price for a new battery in its popular Leaf, but was loudly criticized for that attempt. Today, Nissan is changing gears with a big announcement regarding the price of a new pack for your Nissan Leaf: $5,500 to buy. With an asterisk. Nissan's Brian Brockman, writing at My Nissan Leaf, announced that Nissan Leaf replacement batteries are now available to purchase at certified Leaf dealers in the US at a suggested retail price of $5,499. These packs are the ones found in 2015 Leaf models, which are similar to the ones the Leaf has always had, just with a different, better battery chemistry. To buy a new pack, you need to give Nissan your original battery pack (which Nissan says will be recycled and has a value of $1,000) and the $5,500 "does not include tax, installation fees or an installation kit required for 2011 and 2012 vehicles." That kit costs around $225. A $100/month financing program will still be available (details will be made available later) but now it will have an end date and the driver will own the pack at the end of the payment process. All replacement packs will have the same eight-year, 100,000-mile warranty as the battery in a new Leaf. You can read Brockman's full statement below or over on My Nissan Leaf. Ever since the Leaf entered the market in late 2010, Nissan has been dealing with degrading battery issue, both as a real thing (in warm climates like Arizona) and as a worry in the mind of potential customers. Now that we know how much it'll cost to get a new pack, we can calculate that the overall cost for a new 24-kWh pack is now officially $6,500. That means the price to a customer is less than $270-per-kWh. That's quite low compared to some early estimates, right on target with others and a very big deal for EV shoppers and drivers out there. Hi all: I'm happy to be back to provide a long-awaited update on the Nissan LEAF battery replacement plan. Last year, I posted preliminary details of the program that we'd created based on early survey data, and it led to spirited discussion (and very vocal criticism). So we went back to the drawing board with your comments and the ongoing guidance of the LEAF Advisory Board.

Nissan, Renault break up the Ghosn-style almighty chairmanship

YOKOHAMA, Japan — Japan's Nissan Motor and France's Renault said they would retool the world's top car-making alliance to put themselves on more equal footing, breaking up the all-powerful chairmanship previously wielded by ousted boss Carlos Ghosn. The removal of Ghosn, credited for rescuing Nissan from near-bankruptcy in 1999, had caused much uncertainty about the future of the alliance and some speculation the partnership could even unravel. The companies, together with junior ally Mitsubishi Motors, on Tuesday said the chairman of Renault would serve as the head of the alliance but — in a critical sign of the rebalancing — not as chairman of Nissan. "This is a very special day for the alliance," Renault SA's chairman, Jean-Dominique Senard, told reporters after a meeting at Nissan's Yokohama headquarters. He spoke to reporters along with Renault's chief executive, Thierry Bollore; Nissan CEO Hiroto Saikawa; and Osamu Masuko, CEO of the smaller Japanese alliance partner Mitsubishi Motors Corp. Those four executives will meet every month in Paris or Tokyo and oversee various projects, helping to make the companies' operations more efficient, they said. Nissan has said that Ghosn wielded too much power, creating a lack of oversight and corporate governance. It was not clear who would become Nissan's chairman, vacant since Ghosn was arrested in Japan in November. But the automakers gave no indication of any immediate change in their cross-shareholding agreement, one which has given smaller Renault SA more sway over Nissan. The alliance did not announce any changes in mutual stake holdings. The so-called Restated Alliance Master Agreement that has bound them together so far remains intact, they said. "We are fostering a new start of the alliance. There is nothing to do with the shareholdings and the cross-shareholdings that are still there and still in place," Renault Chairman Senard said. "Our future lies in the efficiency of this alliance," he told reporters at Nissan's headquarters in Yokohama. Senard also said he would not seek to be chairman of Nissan, but instead was a "natural candidate" to be vice-chairman. Former Nissan chairman Ghosn was released on a $9 million bail last week after spending more than 100 days in a Tokyo detention center.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
