Honda revamps F1 engine for McLaren

Things haven't been going smoothly for Honda since returning to Formula One, and the Japanese automaker says the challenge has been greater than it anticipated. But after a stronger showing at the recent Hungarian Grand Prix, Honda says its reliability issues are behind it and is working on introducing a revamped engine for the second half of the season. "I am confident our reliability problems are now behind us, which means we can turn our attention to increasing power," Honda racing chief Yasuhisa Arai told Autosport. "After the summer shutdown our plan is to apply a new-spec engine using some of our remaining seven tokens." The "tokens" to which Arai refers are a way for the FIA to limit engine development. The power units are broken down into 66 such tokens in the regulations, and each engine supplier can change up to 32 of them throughout the season. The allowance was at first afforded only to returning suppliers Mercedes, Ferrari, and Renault, but Honda succeeded in convincing the FIA to allow it the same leeway. Honda has been spending its development tokens on fixing reliability issues, but will shift its focus to improving performance. The McLaren team that Honda powers has only gotten both of its cars to the finish line at two out of 10 races this season. Most of those problems came down to the new engine package. That's compared to only two retirements the team suffered last season, when it was still under Mercedes power, and none the year before. In Hungary, however, the team not only got both cars to the finish line, but placed both in the points for the first time this season. "The sport has changed immensely since the McLaren-Honda 'glory days'," said Arai. "The current technology is much more sophisticated, and it is tough to make a good racing car. We knew it wouldn't be easy, but perhaps we didn't imagine it would be this hard." The Japanese manufacturer is now spending the summer break developing its power unit. Many of those changes are expected to be rolled out in time for the Belgian Grand Prix later this month, with the rest to follow in the ensuing races. Beyond reliability, engine performance is particularly important for the high-speed races at Spa and Monza, where the subsequent Italian Grand Prix will be held early next month. Related Video:

Recharge Wrap-up: Honda Legend Sport Hybrid launching in Japan; driving cross-country on chicken fat

Honda will begin sales in Japan of the Legend Sport Hybrid SH-AWD in January. The Legend is Japan's answer to the Acura RLX Sport Hybrid sold in the US. Up front, the new flagship sedan uses a 3.5-liter V6 with cylinder deactivation and a seven-speed, dual-clutch transmission with integrated electric motor. In the rear, a dual electric motor unit supplies power to the wheels. The three electric motors are also used for generating electricity during deceleration. The car has three drive modes, including EV Drive, Hybrid Drive and Engine Drive. The result is a fuel economy rating of 40 mpg, according to the JC08 cycle.

While Jay Leno explains how marketing early electric cars toward women caused them to lose out to internal combustion, the same can't be said about the current era of EVs. Leno says that early EVs, like Leno's beloved Baker, appealed to women because they were quiet, clean, and didn't require cranking to start them. This led to accessorization marketed toward women, causing men - who had more buying power than women at the time - to shy away from EVs. This time around, though, EVs target a broader audience in a different culture from the early 20th century.

GKN's two-speed eAxle allows EVs to make the most of both acceleration and top speed. Single-speed transmissions must sacrifice top speed for acceleration, or vice versa. In addition to improving performance at all speeds and increasing range, the GKN's eAxle also performs well in terms of NVH, providing seamless shifts and low gear noise. In order to package the eAxle in the BMW i8, the unit is just 12.8 inches by 22.1 inches by 12.3 inches and weighs 60 pounds. Read more at Green Car Congress. An alternative fuels researcher at Middle Tennessee State University will drive a truck powered by chicken fat biodiesel across the country. Professor Cliff Ricketts is driving a converted 1981 Volkswagen Rabbit pickup from Key West, FL to Seattle, WA to demonstrate the viability of chicken fat as a fuel. Ricketts admits, though, that the truck's exhaust stack is loud and smells like French fries. Read more at Domestic Fuel. This content is hosted by a third party.
