SAE World Congress: Honda FCEV fuel cell stack has cells just 1 mm thin

The only update we have for people who are paying ultra-close attention to the progress of the hydrogen-powered Honda FCEV concept is that we now know how thin the individual cells in the car's fuel cell stack are. Speaking at the 2015 SAE World Congress in Detroit this week, American Honda Motor Company Manager of fuel cell vehicle marketing, Steve Ellis, told AutoblogGreen that the fuel cell stack is now 33-percent smaller and offers a 60-percent improvement in power density. We knew this already. What we didn't know is how Honda got there. Ellis said that these improvements are due in part to a reduction in the size of the fuel cell thickness. Each cell in the stack is one millimeter thick, he said. For everyone who isn't counting the millimeters of this car, here's the broader situation. Honda and the state of California (and others) are working hard on getting H2 infrastructure up can running. "The stations are accelerating as we speak," Ellis said. Three new stations have opened in the last few months and the state has pledged $20 million per year until there are 100 stations in California. Honda has also invested in FirstElement to install stations. The production FCEV will feature a range of over 300 miles and have a three-to-five minute refueling time. The car will launch in Japan in March 2016, with US and European sales starting at some unspecified time after that.

Honda unveils new 3.5-liter racing engine

Honda is following Ford's lead and debuting the second twin-turbocharged V6 to be used by Daytona Prototypes in the United Sports Car Championship. The wait won't be long to see it on track because the new engine will debut with the Starworks Motorsport team in a Riley Gen3 prototype chassis at the 12 Hours of Sebring from March 12-15.
The new HR35TT engine is based on Honda's J35 production V6 found in a variety of its models, including the current Accord. The racing version benefits from dry sump lubrication, but is still similar to the production version with an aluminum block, direct injection and single overhead camshafts. It is fueled by 100-octane E10 fuel, but like many racing engines, exact power figures have not been released.
Starworks has had a close relationship with Honda since it won the LMP2 class at the 24 Hours of Le Mans and in the FIA World Endurance Championship in 2012 with a Honda Performance Development ARX-03b chassis and Honda engine. We can't wait to see this new mill hit the track, and see how it fairs against Chip Ganassi Racing's EcoBoost-powered Riley. Scroll down to read the press release for the full details.

U.S. auto sales fall in July, as Detroit dials back on inventory, rental sales

DETROIT — U.S. carmakers said on Tuesday they continued to slash low-margin sales to daily rental fleets in July as General Motors, Ford and Fiat Chrysler Automobiles struggled to curb a slide in retail sales. July is on track to be the fifth straight month in which the annual pace of car and light truck sales declined from the same month a year ago, in part because of fewer fleet sales, analysts and industry executives said. July 2016 sales hit a strong 17.9-million-vehicle pace. GM said the seasonally adjusted annual sales rate fell to an estimated 16.9 million vehicles in July. At midmorning on Tuesday, GM shares were down 3.4 percent at $34.77, Ford was down 2.8 percent at $10.91, and Fiat Chrysler shares were down 0.3 percent at $12.05 in New York. GM sales dropped 15 percent from a year ago to 226,107 vehicles, as the company cut rental fleet sales more than 80 percent. The automaker said inventories of unsold vehicles at month's end were 104 days, down from 105 days at the end of June. GM has promised investors to reduce inventories to 70 days by year-end. Ford said its July sales dipped 7.5 percent to 200,212 vehicles, as it cut fleet sales more than 26 percent. Inventories fell to 77 days from 79 the previous month. Fiat Chrysler said sales dropped 10 percent to 161,477, as it also cut back sales to daily rental fleets. Among the top Japanese companies, only Toyota reported a year-to-year gain, with sales up 4 percent to 222,057 — just 4,000 units behind GM. Honda sales were down 1 percent to 150,980 — its first-quarter sales continuing to decline in North America but seeing a big increase in China. And Nissan sales fell 3 percent to 128,295. GM, Ford and Fiat Chrysler have cautioned that second-half financial results likely will be lower than first-half results, in part reflecting production cuts in North America and pricing pressures. The automakers this year have been deliberately dialing back sales to rental-car companies, which often generate little to no profit, while struggling to keep retail sales from sagging further, according to industry analysts. Industry consultant LMC cut its full-year forecast for new vehicle sales to 17 million vehicles. Automakers sold a record 17.55 million vehicles in the United States in 2016.
