Recharge Wrap-up: Tesla will sell Model S on Alibaba in China, Wrightspeed electrifies garbage trucks

Tesla will sell cars in China using Alibaba's Tmall website. Customers will be able to use the Chinese shopping site to place an $8,200 deposit toward a Model S. Tmall will feature 18 preconfigured versions for customers to choose from, which won't offer quite the level of customization as Tesla's US site. Bloomberg's Jamie Butters calls it a "defensive move" on Tesla's part, and still expects the company to sell cars in China the traditional way. Watch the video at Bloomberg or read more at Bidness Etc. Tesla co-founder Ian Wright's company Wrightspeed is converting garbage trucks to EVs. The same brand that created the exciting X1 EV is making trash collection much cleaner. "Garbage trucks are the perfect driving cycle for us: they get two or three miles per gallon, drive 130 miles a day with 1,000 hard stops that chew on the brakes," says Wright. The system puts an electric motor at each of the truck's drive wheels, and includes an on-board generator that runs on diesel or natural gas to extend driving range. Read more at Xconomy. British company Hillside Leisure is converting the Nissan e-NV200 into a camper van. The electric RV, called the DalburyE, debuted at the UK's Motorhome and Caravan Show in Birmingham. It sleeps up to four people, and features a pop-up roof, a gas stove, fridge, sink and other amenities. It's a great way to take full advantage of an RV park's electrical outlet to charge the van while camping in it. Read more at Transport Evolved, and see more photos at Hillside Liesure's blog.

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.

You'll soon be able to buy an EV in China for just $8,000 after incentives

Renault is eventually looking to sell an electric vehicle in China that will cost as little as $8,000 after government incentives kick in. According to Reuters, Renault-Nissan chief Carlos Ghosn offered the prediction at the New York Times Energy for Tomorrow conference in Paris this week. Granted, China government incentives are approaching $20,000 per vehicle, as China looks to address its cities' notorious pollution problem, so there's some wiggle room with that price. And of course, the devil is in the details, and Ghosn didn't provide any. Still, such a low-priced EV would likely challenge the dominance of China-based EV makers BYD and Kandi. And the effort would likely be lucrative, given that it has been predicted that China will become the world's largest EV market by the end of the decade. In fact, the publication EV Sales said earlier this year that as many as 300,000 EVs will be sold in China in 2016 (by comparison, Americans bought about 100,000 EVs and plug-in hybrids combined through the first 10 months of the year). BYD is expected to sell 75,000 Tang SUV units this year. With such growth expectations in mind, automakers are focusing on China for potential EV development. Earlier this year, Volkswagen Group said it signed a memorandum of understanding with China's Jianghuai Automobile (JAC) for plug-in vehicle production. Mercedes-Benz parent Daimler also stated its goal to broaden plug-in vehicle sales in China. Renault appears to be trying to make an early mark in China. Dongfeng Renault Automobile Co., the Chinese joint venture between Renault and Donfeng, is looking to start testing a self-driving electric vehicle this month. Dongfeng Renault will use a 1.5-mile stretch of road in Beijing's Caidian district for testing purposes. Related Video:
