Red Bull F1 denied access to Honda engines

There are four engine manufacturers in Formula 1: Ferrari, Honda, Mercedes-Benz, and Renault. Infiniti Red Bull Racing ended its marriage to Renault, got to the altar with Mercedes and then Mercedes backed out, couldn't even agree on a pre-nup with Ferrari, and Honda flat-out said, "No." At the moment that has left the four-time World Champions without an engine for next year, owner Dieter Mateschitz threatening to take his two teams and four cars out of the sport, and F1 honcho Bernie Ecclestone threatening to sue Mateschitz if he does. The Japanese company had turned down the idea because after a first year with some poor performances and a few public sour notes, it wants to get McLaren's cars running properly before it expands its operation. Now it seems some behind-the-scenes action of late has opened up channels between Red Bull and Honda, and the two are at least talking. Honda, though, still says such a deal is highly unlikely at best, and Red Bull says it will have something to say when something is done. It appears that McLaren chief Ron Dennis, however, has vetoed the idea. Ecclestone says Honda made a deal with the FIA that would allow Honda to supply two teams in its second year, but Honda gave Dennis veto rights over who the second team would be. For the same reason that Mercedes backed out and Ferrari only wanted to sell Red Bull year-old engines, Ecclestone says Dennis might view Red Bull as a competitor and doesn't want to risk two more cars getting in front of his own. If that's the case and Red Bull is going to remain in the sport, it might need to hit the flower shop and book a trip to Renault headquarters. Soon. Related Video:

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.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
