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.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

Would you pay $17 a month to give your older Ford connectivity?

When it was first introduced in 2007, there was nothing like the original Ford Sync system, since it allowed car owners to connect and use a portable device better than anything that came before it. And because it was a brought-in/tethered and software-based system, Sync leveraged a device's connectivity and was easily updated. It took competitors awhile to catch up: Toyota Entune wasn't available until 2011, and Chevy MyLink didn't roll out until 2012. But now Ford is the one playing catchup since it stuck with the brought-in strategy while most other automakers were quicker to add connectivity via an embedded cellular modem. Ford initially installed 2G/3G modems in its small fleet of electric and plug-in electric vehicles starting in 2012 so that owners could keep tabs on charging. Embedded connectivity came to Lincoln in 2014, and Ford began adding onboard 4G LTE via Sync Connect to select cars starting with the Escape in 2015. To get more cars connected more quickly, last week the automaker rolled out its FordPass SmartLink solution that plugs into the OBD port of 2010 to 2017 model year vehicles. This lets owners retroactively get onboard Wi-Fi, set up a "geo-fence" to keep tabs on a car's location, receive vehicle health reports and allows remote engine starting and door locking/unlocking using a smartphone app, among other features. But to connect older Ford vehicles will cost owners $16.99 a month for two years, not including installation. Ford throws in 1 GB of data or a 30-day trial, whichever comes first, after which owners have to add the vehicle to their Verizon shared data plan, which supplies connectivity for SmartLink, or establish a new account. (Disclosure: Autoblog is owned by Verizon.) By comparison, GM's 4G LTE data plans start at $10 a month for 200 MB and goes up to $30 for 3 GB, and owners can also add a car to an AT&T shared-data plan. But OnStar doesn't have a separate monthly subscription for the embedded modem or an installation charge, and standard features via the RemoteLink Mobile App are free for the first five years of ownership. FCA's Uconnect Access service also uses an embedded modem to provide similar telematics features for $20 per month following a free one-year trial, while a la carte in-car Wi-Fi is offered for $10 per day, $20 per week or $35 per month.
