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.

Here's what the UAW will be angling for in next year's contract negotiations

The United Auto Workers union is about to enter a new round of negotiations with the Detroit Three automakers, and this time, the focus is on the end of the two-tier wage system. Introduced in 2007, the two-tier wage system was enacted to allow General Motors, Ford and Chrysler to categorize its hourly employees under two categories: Tier 1 for veteran employees with full rights and benefits, and Tier 2 for short-term or entry-level employees compensated under a different schedule. The idea was that the system would permit the automakers to invest more in their plants and hire new employees as part of their respective recovery plans without being saddled with all the costs associated with hiring full-time employees. Now that the automakers are (more or less) back on their proverbial feet, however, the UAW wants to see an end to the two-tier system, and will likely make that a center-point of its negotiations next year to replace the current arrangement that is scheduled to end in September 2015. Not all members of the UAW will necessarily be interested in ending the two-tier system, however. According to The Detroit News, some Tier 1 workers may be more interested in negotiating a raise in their hourly rate – something which they haven't received in almost a decade. Tier 2 workers, meanwhile, may be more motivated to keep the tiered system in place, as their arrangement includes provisions for profit-sharing payments that have seen the automakers pay out billions to so-called short-term employees in lump-sum payments. Reconciling the two competing demands from two categories of union members and presenting a united front in negotiations may prove the biggest challenge for the UAW's new president, Dennis Williams. And with the right to strike – something which was suspended during the last round of negotiations in 2011 – the union has a bigger bargaining chip in its pocket.

VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.
