Nissan-Dongfeng JV reveals Venucia VOW concept in Shanghai

Among the dozens of automakers pouring in to the Shanghai Motor Show this week to showcase their latest wares, this one comes from a brand you may never have heard of. It's called Venucia, and it's the product of a joint venture between Nissan and Chinese automaker Dongfeng. Today Venucia has unveiled the VOW Concept, a sporty-looking crossover designed to appeal to young Chinese buyers and previewed in a teaser rendering last week. The design is said to have been inspired by the Salar de Uyuni plateau in the Bolivian Andes, but reminds us a bit of the Lamborghini Urus and Mitsubishi XR-PHEV concepts. And that's no bad thing. Technical details are few and far between, but the name VOW apparently stands for "Venucia Over Wonder," that brand name itself having been derived from the Roman diety Venus. Beyond that we couldn't tell you any more, but even if the VOW concept gets put into production, the chances are slim to none that any version would ever reach a showroom on our side of the pond in the foreseeable future. Venucia debuts VOW Concept at Auto Shanghai 2015 SHANGHAI, China – Venucia, a local brand by Dongfeng Nissan Passenger Vehicle Company (DFL-PV), the passenger vehicle business unit of Nissan's joint venture in China, unveiled the VOW Concept at Auto Shanghai 2015. VOW Concept, a brand new trendy sport crossover concept by Venucia, was developed for the young generations. VOW is the abbreviation of "Venucia Over Wonder," meaning a complete breakthrough in excellence. The forward thinking and bold design is paired with a bright blue body inspired by Bolivia's Salar de Uyuni, a high plateau near the crest of the Andes Mountains with captive fresh and saltwater lakes and the world's largest salt flat. VOW Concept conjures up a new balance of dynamic excellence and elegance. "With the VOW Concept, Venucia is going directly to the young generations and listening to what they have to say about their futures, their hopes and what inspires them. We are determined to bring forward a young and fresh brand that continues to challenge the status quo," said Zhou Xianpeng, DFL-PV deputy managing director. "We believe Venucia will lead future trends as an influencer, and enhance its place in the automotive market in China."

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.

Recharge Wrap-up: utility sells discounted Powerwall, Nissan-Renault builds 340K EVs

Vermont electric utility Green Mountain Power is selling discounted Tesla Powerwalls to its customers in hopes of balancing the grid. The battery packs would be used not just to help customers store renewable energy for home solar systems or as backup power, but also to occasionally discharge power back to the grid when needed. In addition to this decentralized energy storage being useful to customers, it also benefits the utility by taking demand off energy generating infrastructure during periods of peak demand. The pilot project will put 500 Tesla Powerwalls in customers' homes. Learn more at Green Car Reports, or in the story from Vermont Public Radio. Together, Nissan and Renault have built 340,000 electric cars. The allied Japanese and French automakers hit 100,000 EVs in July 2013, 200,000 in November 2014, and a quarter million in June of 2015. The Nissan Leaf, which first went on sale at the end of 2010, makes up the bulk of the EVs the Renault-Nissan Alliance has sold. Renault delivered its 50,000th Zoe EV in April 2016. Leaf sales have declined in the US in recent months, due at least in part to the anticipation of the Chevrolet Bolt and Tesla Model 3. Nissan, however, is expected to update the Leaf with a 200-mile driving range in the coming years. Read more at Green Car Reports. Students at the Bearys Institute of Technology (BIT) in Karnataka, India have built what they call the Hybrid Water Car. The car uses a system to electrolyze hydrogen from water and add it to the fuel for more efficient combustion. The system has been placed into a chopped up, lightweighted Maruti Omni. While the benefits of onboard hydrogen electrolyzers have been debated for some time, the BIT students don't plan to stop there, as their next project car will be fueled completely by hydrogen.
