2015 Bentley Mulsanne Speed

Why does the Bentley Mulsanne Speed exist? Sam Graham, product line director for the Mulsanne, tells us Bentley's Western customers demanded it, many driven by memories of the Arnage T - the hotted-up version of the Arnage R. The Arnage T, you may remember, arrived in 2002 and threw down 459 horsepower and 645 pound-feet of torque on its way to being billed the most powerful production Bentley ever. Today's Mulsanne Speed picks up the torch and takes it all the way to the Olympic stadium.
Driving Notes
It starts with an upgrade to 530 hp at 4,200 rpm and 811 lb-ft of torque at a limbo-esque 1,750 rpm. That's an additional 25 hp and 86 lb-ft compared to the standard sedan, enabling a top speed of 190 miles per hour. That torque figure makes it second only to the Bugatti Veyron among production cars, and that terminal velocity makes it the fastest ultra-luxury sedan on God's Own Green.

Bentley Bentayga plug-in hybrid spied using V6 power

Bentley confirmed plans for a plug-in hybrid version of the Bentayga in early 2015 and said the electric SUV would be ready for 2017. It seems that the luxury automaker will keep its word, because one of our spy photographers spotted this nearly undisguised model out testing. It looks identical to the normal Bentayga, with the exception of an additional little flap on the left side for a plug. Although Bentley confirmed the hybrid's development way back in 2015, it left out a few details about what the powertrain would be, only saying it would either be a V8 or a V6. Our spy photographer was able to shed some light on this by looking up the prototype's registration. Apparently it has a 3.0-liter engine under its proud hood, so it's a reasonable bet the Bentayga has a V6. Since Bentley promised the hybrid would be ready for 2017, and because this car is hiding almost nothing, we would expect to see the car make a full debut by the end of the year. It should have an electric range of just over 30 miles.

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. You can see how the ACEEE determines its rankings here, explore the entire greenest cars site here, or click through our galleries to see which vehicles are extra green (above) or extra mean (below) this year. 12: Mercedes-Benz GL550 4MATIC View 12 Photos More Electric Cars than Ever on Greenest Vehicles List Electric Vehicles Nab 9 out of Top 12 Spots in ACEEE's Environmental Vehicle Rankings Washington, DC: Despite a tumultuous year for the automotive industry, manufacturers have continued to offer exciting technology options for a growing vehicle market.
