2017 Bentley Mulsanne Extended Wheelbase is for the driven

For the first time since the nameplate was reintroduced as a 2011 model, Bentley will offer the Mulsanne in two lengths. The Extended Wheelbase adds an additional 10 inches to the rear passenger compartment over the standard and Speed models, allowing Bentley to fit a pair of reclining rear seats and a large sunroof into its flagship model. Naturally, this is the Bentley model aimed at buyers who would rather not drive themselves, preferring to be chauffeured. That doesn't describe the average Autoblogger, but for those who do fall into that camp, here's what you should know. View 8 Photos It's coming to America. Although the Mulsanne Extended Wheelbase will be aimed mostly at the Asian market, it will come to the United States. Most Americans would rather drive than be driven, which means the long-wheelbase model will be imported from England in very small numbers and quite likely as a limited edition. For such a simple idea, the execution is complicated. Every Bentley Mulsanne is hand-assembled by a skilled team of craftsmen. That doesn't change for the Extended Wheelbase, but it does add some new complexity to the build process. All three Mulsanne models roll down the same line in Crewe, meaning workers have to be trained in the differences of each model. This is true at most plants, but the assembly of a Mulsanne is a rather different process than a Mustang. In addition to the extra length, all Mulsanne Extended Wheelbase models get optional folding tables for both rear passengers. These are beautiful works of art, and the engineering behind them is almost unbelievable. Each tray table is made from 600 individual parts. Yes, you read that correctly. We're not sure how Bentley managed to over-engineer these baubles so thoroughly, but we suggest that you treat the metal and leather creations with respect. But it's also very comfortable. Those tray tables can tilt at about a 30-degree angle, which is perfect for displaying content on an electronic device. The center console that holds them when not in use is unique to the Extended Wheelbase, and it's covered in the same veneer and leather that the buyer selects for the rest of the car. USB ports, pen holders, and cup holders designed specifically to hold two of the three crystal flutes in the fridge between the seats, and a glass-covered bin make the console as useful as possible.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

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.
