Honda Performance Development reveals new ARX-04b LMP2 coupe

Make no mistake about it: Honda is big in racing. It was the first Japanese automaker to enter Formula One, remains the most successful and is set to return as an engine supplier next season. It's powered more IndyCar race winners and champions than any other manufacturer, hands down. Honda has won races and titles in Super GT, WTCC, even motorcycle racing. Just about everything this side of NASCAR, really. And that includes endurance sports car racing.
In fact Honda Performance Development prototypes claimed over 70 victories and numerous titles in the American Le Mans Series, and took the first LMP2 title in the FIA World Endurance Championship. And with sportscar racing in the US now grouped together into the United SportsCar Championship, Honda is back with a new chassis design.
Called the ARX-04b, it's Honda's first closed-cockpit LMP2. Like previous LMP2 and IndyCar projects, it's a joint development between HPD and Wirth Research, and packs Honda's HR28TT engine - a 2.8-liter twin-turbo V6 based on (and using many of the same components as) the J35 engine you'd find in a contemporary Acura. Designed to exceed the latest safety regulations, the ARX-04b features low-drag bodywork, quick-change front and rear panels, the same locking fuel filler system that Honda pioneered for Indy, top-exit exhaust to meet noise regulations, a 75-liter fuel tank and a gearbox that can easily be optimized for individual circuits.

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.

Honda Accord Hybrid falls well short of 47 mpg, says Consumer Reports [w/video]

Do not poke Consumer Reports with the hybrid fuel economy stick. That seems to be the lesson illustrated here yet again. The Honda Accord Hybrid is the latest to arouse the ratings bear, returning "just" 40 combined mpg in CR testing. Even so, that makes it "a class leader for fuel economy among midsized sedans," besting even the Civic Hybrid in CR testing, but that's still a lucky roll of the dice short of its EPA rating of 47 mpg. Remember, it was back in December 2012 that CR knocked the Ford Fusion and C-Max hybrid models for the exact same failing: certified with an EPA-rated 47 mpg but delivering "just" 40 mpg.
Beyond that, while the Accord Hybrid earned a lower overall score than the traditional gasoline Accord because of its ride, handling and refinement issues, it gets unqualified applause from the institute for its "very impressive hybrid system."
It will be interesting to see if CR's findings will negatively impact the model's sales, which to this point have been impressive enough that demand is outstripping supply. In the meantime, you can check out CR's brief video review of the Accord Hybrid below, and check out the magazine's press release chiding its mpg rating.
