Recharge Wrap-up: Ford HQ gets giant solar array, Chevy City Express gets 24 MPG city

Ford will be building Michigan's largest solar array at its Dearborn headquarters. With funding from DTE Energy, the solar carport will provide covered parking, as well 30 charging stations for electric vehicles. The array is expected to generate 1.13 million kWh per year for Ford's operations, and offset 794 metric tons of carbon emissions. Read more in the press release below. Chevrolet announced the fuel economy for the 2015 City Express, at 25 mpg combined. The cargo van is rated at 24 mpg in the city, and 26 mpg on the highway. Chevy credits the van's inline four-cylinder engine and continuously variable transmission for its impressive city mileage. For its customers - which are mainly businesses - "The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business," says Chevrolet's Ed Peper. The City Express starts at $22,950. Read more in the press release below. Engineers at the University of Wisconsin have developed an efficient engine that runs on a diesel-gas blend. The engine, which uses a computer to control the blend proportions, is about 15 percent more efficient than the any diesel engine according to mechanical engineering professor Rolf Reitz. The team has put the experimental reactivity controlled compression ignition (RCCI) engine in a demonstration car - a 2009 Saturn. "This vehicle can do 50 miles per gallon," says Reitz, who believes the system could be improved further. Read more at Wisconsin Public Radio. The Southeast Alternative Fuel Conference and Expo will take place in October in Raleigh, North Carolina. Held at the NC Clean Energy Technology Center from October 22-24, the event will feature a variety of exhibitors, speakers and, most importantly, alternatively powered vehicles. "The three day conference will be a one-stop shop for fleet and transportation related decision makers to learn about return on investment, efficiency and alternative transportation fuels such as biodiesel, electricity, ethanol, propane and natural gas," says Anne Tazewell of the NC Clean Energy Technology Center. If you can't make it to Raleigh for the Expo, you can still enter to win a free two-year lease of a Nissan Leaf at the Center's website. Learn more about the event in the press release, below.

Chevy Volt gets customer satisfaction 'recall' for rear hatch issue *UPDATE*

Last week, General Motors has issued a "Customer Satisfaction program" for some 2011-2015 model year Chevrolet Volts to fix the manual rear lift gate not working as appropriate. According to Volt owner posts on Facebook, the problem manifests itself by the hatch not opening up all the way (sometimes worse in the cold) with some people bumping their heads. Dealers will replace the lift gate struts as part of the program. Some drivers were notified through the vehicle's OnStar system that there is a problem. GM has not yet said how many Volts are affected. *UPDATE* This program is for all 2011-2015 model year Volts. Chevrolet spokesperson Michelle Malcho told AutoblogGreen that, "This is not a recall, so there won't be any formal information posted on the GM website." The fixes will be free to affected Volt owners. Some 2010-2015 Cadillac SRX vehicles are also affected by the same problem and will also be fixed.

Diesel details: Comparing Ram 1500 EcoDiesel, Chevy Silverado Duramax, Ford F-150 Powerstroke

With specifications for the 2019 Ford F-150 Power Stroke diesel already out, and the details on the 2020 Ram 1500 EcoDiesel and Chevy Silverado Duramax (and its GMC Sierra twin) trickling out, we felt it was a good time to start comparing the full-size trucks' light-duty diesels. Bear in mind, we've only driven one of these new diesel trucks, so we'll be sticking to numbers for now. Some numbers haven't been announced yet, either, but stay tuned, because we'll be updating this post with additional specifications as they become available. And if you want to compare any other versions of these trucks with other vehicles, be sure to check out our comparison tool. Now let's start comparing, starting with our big chart of numbers below. As we can plainly see, these trucks are quite closely matched. Each one has six cylinders, a displacement of 3.0 liters and a turbocharger to boost it. The output of each is somewhat close, too. The Ram 1500 EcoDiesel is the torque king at 480 pound-feet, 20 more than the GM trucks and 40 more than the Ford. The GM trucks win on power, though, with 277 ponies, 17 more than the Ram, and 27 more than the Ford. GM does report that you get their trucks' peak 460 pound-feet of torque from 1,500 rpm to 3,000 rpm, whereas the others only report peak torque at a particular point in the rev band, but all of these trucks should have wide, flat torque curves as you would expect from modern turbodiesels. 2020 Ram 1500 EcoDiesel View 8 Photos Engine output is only one part of the truck performance equation. We also have towing and payload capacity, as well as fuel economy. With towing, the Ram 1500 is the current leader with a maximum capacity of 12,560 pounds. That tops the Ford F-150's 11,400-pound tow rating by well over 1,000 pounds. The F-150 can carry 2,020 pounds in its bed, but we don't know yet whether that's better or worse than the Ram or the GM trucks. We also don't have numbers for the GM trucks' towing capacities. View 9 Photos As for fuel economy, the Ford F-150 manages a thoroughly impressive 22 mpg in the city and 30 on the highway with two-wheel drive. Choosing four-wheel drive drops those numbers to 20 and 25 respectively. The fuel economy numbers for the Ram, Chevy and GMC haven't been revealed yet, but for some comparison, we can look at the old Ram EcoDiesel. That truck's best fuel economy was 20 in the city and 27 on the highway with two-wheel drive.
