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.

Average new-car fuel economy figures continue record pace

Manufacturers are making more efficient cars and trucks; we've known that to be true for some time. Nearly every new car has some sort of trick to eke a few extra miles out of every gallon of fuel. Whether that be turbocharging, active aerodynamics or hybrid technology/electrified powertrains, the fact is that our vehicles are more efficient than ever before.
Thanks to a recent study by TrueCar, we've got fresh quantitative data to support the above statements. For the fourth month in a row, we've seen an improvement in national fleet fuel economy. We Americans are 0.7 miles per gallon more efficient than we were last month, and our cars are 1.6-mpg better than at this time last year. That said, we're still down on 2013's high, which was set back in January at 24.5 mpg.
Not only does this reflect the improved technologies in our vehicles, but it demonstrates a changing mindset among consumers, who are purchasing more efficient vehicles despite the relative stabilization of fuel prices. Every fuel-efficient model sold drives its manufacturers fleet average up.

Watch two Acura NSXs scorch the Nurburgring

Some intrepid spy shooter captured these two Acura NSXs blasting around the Nurburgring. Without being there in person with a decibel meter, it's hard to tell if they're necessarily louder than stock cars, but they sure seem quick. Why test the cars now, when they've been on sale for a while now? Rumors are swirling that this could be a hardcore variant. It's unclear if Honda would call it a Type R, but a midlife refresh with a bit more power or a special limited edition with some extra kick wouldn't be unprecedented. The original NSX had several such models, and recent sports cars like the S2000 had low-volume editions, like the Club Racer variant in the United States and the Type S in Japan. Watch the video and draw your own conclusions about what this is or isn't. One thing's for sure: It's not a pure-EV variant. In other things recent about the NSX, we learned last month that an NSX GT3 non-hybrid race car version will go on sale soon. And here's our first drive of the US Acura-badged NSX from back in 2015. And here's another video from inside the cockpit during an open track day back in June.
