2014 Nissan Leaf named overall cleanest car in US

A research firm has named the zero-emission 2014 Nissan Leaf the cleanest production vehicle in the US, and that's figuring in the full, wheel-to-well lifetime impact of the car on the environment. The Automotive Science Group (ASG) studied more than 1,300 automobiles with at least four seats across nine categories, measuring everything from the amount of fuel needed to run the car during its lifetime to the extraction of natural resources to build the thing in the first place to end-of-life processing. ASG calls the process "wildly complex." The battery-electric Leaf, with its 84-mile single-charge range, took top honors overall, but there were other highly ranked vehicles in different categories. ASG also said that the Mitsubishi Mirage, with its sub-2,000-pound curb weight and 40 miles per gallon fuel economy, was the cleanest among gas-powered vehicles, while the Chevrolet Spark had the lowest cast of ownership over five years. Last month, the American Council for an Energy-Efficient Economy (ACEEE) put together its annual "Greenest" and "Meanest" (notice: we didn't say "Cleanest") lists and put the Leaf at number three. Topping that list was the Smart ForTwo ED battery-electric, but that was followed up by the Toyota Prius C compact hybrid, so fans of those vehicles can now start a healthy debate. The ACEEE uses data from the Environmental Protection Agency and California Air Resources Board to compile its list. We have ASG's press release below. Life-cycle Assessment of 1,300 Models Reveals Best of 2014 FOR IMMEDIATE RELEASE 4 February 2014 [Santa Rosa, CA] – The Automotive Science Group (ASG) conducted a comprehensive life-cycle assessment of over 1,300 automobiles across nine categories to distinguish the BEST model year 2014 vehicles in environmental, economic, social and "all-around" performance. Auto consumers are now equipped with a car buying guide founded on principled facts, a departure from the notoriously subjective test drive "editor reviews" that have long been the industry norm. Using a unique combination of vehicle data inputs that include conventional specifications as well as ground-breaking social, environmental and economic performance indicators, ASG's back-end algorithms are wildly complex, but the front-end results – meaningful vehicle ratings and distinguished awards – are forthright and consumer-friendly. ASG's Automotive Performance Index is for automotive consumers what Google is for web users.

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.

Infiniti replaces Americas chief

The Nissan-Renault alliance has been something of a revolving door for high-level executives of late, and the latest shakeup comes at its luxury unit, Infiniti, where Michael Bartsch (shown above) has been replaced as vice president of its Americas division by Randy Parker. Bartsch had a short tenure – he only took the helm in September 2013. In a press release, Infiniti said he was leaving to "pursue other interests." Bartsch, a veteran of more than 30 years in the auto industry, came to Infiniti from Porsche. Parker comes from within the Nissan empire, formerly heading up the company's sprawling west region, including its marketing, distribution and dealer network. Before that, he served stints at GMAC and General Motors. Bartsch isn't alone in leaving Renault-Nissan recently. Ex-Renault COO Carlos Tavares took the top spot at Peugeot, Infiniti boss Johan de Nysschen left for Cadillac and Nissan executive vice president Andy Palmer took over at Aston Martin.
