Recharge Wrap-up: Honda releases "Green Dealer" Guide, Tesla's China president steps down

Honda has released its "Green Dealer" Guide to the public. The guide, which is used to outline ways for Honda and Acura dealerships to be more environmentally responsible can also help other businesses take the same steps to green up their practices, save energy and even save money in the process. The guide, which ranks dealers based on a points system, provides incentive to dealerships to implement the environmentally practices, but it also helps Honda assert itself as a leader for green business.

According to a survey by Nissan, 93 percent use the EV as their main family vehicle. 89 percent report saving money driving, 64 percent prefer it to driving a conventionally powered car and 95 percent would recommend the car to a friend. Most said they wouldn't go back to a gas or diesel car. One owner even gave up his Aston Martin for a second Leaf so he and his wife wouldn't argue over who got to drive the EV to work each day. That's love. Read more at Next Green Car and at Hybrid Cars. Renault has outlined its future sustainable mobility plans, including two pieces of technology going into production cars soon. Renault will put a smaller, more efficient electric motor into production, as well as a three-cylinder dual-fuel gasoline/liquid petroleum gas engine. The HYDIVU prototype will help Renault research mild hybrid technology for light commercial vehicles. The VELUD project will look into making the last mile of urban deliveries more sustainable. Renault is also testing a two-cylinder, two-stroke diesel engine for small vehicle platforms. Read more in the press release below. Tesla's China president has resigned. Veronica Wu had been in charge of the company's operations in China for the past nine months, and with her leaving the company, Tom Zhu will step into the role. Jochen Siebert of Shanghai-based JSC Automotive Consulting says that, "Tesla counts on China as one of their main drivers of growth after California, and it might have been more difficult than they thought." Tesla states it is still "confident in the Chinese market," where it has sold the Model S since April. Read more at Bloomberg.

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.

Nissan lowers price of seven models for better search results

Intent on not eliminating itself from consideration, and adapting to the way consumers research new car purchases, Nissan has announced price discounts now in effect, indefinitely, on seven models: the Altima, Armada, Juke, Maxima, Murano, Rogue and Sentra. It was found that Nissan's price points fell outside the competitive pool when prospective buyers searched for cars based on maximum price.
The price cuts vary and depend on the equipment spec, but they range from several hundred dollars to thousands of dollars; the MSRP of the Altima drops by $580, the Sentra by $730, the Armada by $4,400. Discounts on the Murano alone range from $1,460 to $2,410. Under orders from CEO Carlos Ghosn the brand is working to raise its US market share to ten percent by 2016, from 7.9 percent currently - which includes Infiniti - and appears to be optimizing its placement every step of the way to do so.
