Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.

2.1 million vehicles recalled again over faulty airbags

Fiat Chrysler Automobiles, Honda and Toyota will recall 2.1 million vehicles to fix faulty airbag modules "after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles." These vehicles had all previously been recalled, but the National Highway Traffic Safety Administration found that the airbags could still potentially malfunction. This recall will cover Acura MDX, Dodge Viper, Jeep Grand Cherokee, Honda Odyssey, Pontiac Vibe, Toyota Corolla, Toyota Matrix and Toyota Avalon models made in the early 2000s. NHTSA has reportedly received about 40 reports of airbag deployment in such vehicles, even though the vehicle had not been involved in a crash. Roughly one million of these same vehicles, all from Honda and Toyota, are also subject to recalls due to faulty Takata airbag modules, though this particular recall is for "an electronic component manufactured by TRW" that is separate from the actual airbags from Takata. According to NHTSA Administrator Mark Rosekind: "This is unfortunately a complicated issue for consumers, who may have to return to their dealer more than once. But this is an urgent safety issue, and all consumers with vehicles covered by the previous recalls should have that remedy installed. Even though it's a temporary solution until the new remedy is available, they and their families will be safer if they take the time to learn if their vehicle is covered and follow their manufacturers' instructions. A hassle is much better than a family tragedy." If you're the owner of an affected car, expect to hear more from the official automaker and government channels in short order. In the meantime, we'd suggest getting your car checked and fixed at your local dealer. The official statement and recall information can be found below. Previously Recalled Vehicle Remedies Not Working as Designed; NHTSA Announces Follow up Recall of 2.12 Million Cars and SUVs Saturday, January 31, 2015 Contact: Gordon Trowbridge, 202-366-9550, Public.Affairs@dot.gov WASHINGTON – U.S. Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles for a defect that may cause airbags to deploy inadvertently. The recalls will provide vehicle owners with a new remedy after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
