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.

At meeting with automakers, Trump launches new attack on NAFTA

WASHINGTON — Ten American and foreign automakers went to the White House on Friday to push for a weakening of U.S. fuel efficiency standards through 2025, while President Donald Trump used the occasion to launch a fresh attack on the North American Free Trade Agreement that has benefited the companies. A draft proposal circulated by the U.S. Transportation Department would freeze fuel efficiency requirements at 2020 levels through 2026, rather than allowing them to increase as previously planned. Trump's administration is expected to formally unveil the proposal later this month or in June. "We're working on CAFE standards, environmental controls," Trump told reporters at the top of the meeting, referring to the Corporate Average Fuel Economy standards for cars and light trucks in the United States. Trump said he wants automakers to build more vehicles in the United States and export more vehicles. But much of the hour-long meeting focused on NAFTA. Trump blasted the pact involving the United States, Canada and Mexico as "terrible" and noted that negotiations to make changes sought by his administration were ongoing. "NAFTA has been a horrible, horrible disaster for this country and we'll see if we can make it reasonable," Trump said. Automakers have called NAFTA a success, allowing them to integrate production throughout North America and make production competitive with Asia and Europe, and have noted the increase in auto production over the past two decades with the deal in place. They have warned that changing NAFTA too much could prompt some companies to move production out of the United States. The chief executives of General Motors Co, Ford Motor Co, Fiat Chrysler, along with senior U.S. executives from Toyota Motor Corp, Volkswagen AG, Hyundai Motor Co, Nissan Motor Co, Honda Motor Co , BMW AG and Daimler AG met with Trump, as did the chief executives of two auto trade groups. Major automakers reiterated this week they do not support freezing fuel efficiency requirements but said they want new flexibility and rule changes to address lower gasoline prices and the shift in U.S. consumer preferences to bigger, less fuel-efficient vehicles.

Wolff: Honda will emerge as strong F1 force

Mercedes motorsport boss Toto Wolff has no doubts that Honda will make a success of its Formula 1 return, despite the Japanese manufacturer's disappointing time last year. Honda endured a troubled return to F1 in 2015 as it struggled with reliability and a lack of power from its new turbo V6 hybrid engine. But having made gains over the campaign, and a significant revamp of key elements of its power unit over the winter, Wolff thinks that Honda is on course to deliver. "Honda is a huge organization with lots of resource, and they were the power unit with the most impressive development curve through 2015," Wolff said in an interview with his Mercedes team's YouTube channel. "Even if it was a very difficult year for them, it was still very good what they achieved in terms of how they progressed through the season. I have no doubt they will be a strong competitive in the future." Wolff's comments come despite Mercedes engine chief Andy Cowell saying last week that he was not convinced that Honda's 'size zero' concept was the right approach for the current regulations. Manor step As well as predicting good things for Honda in the future, Wolff has predicted promising results for the Mercedes-powered Manor team in 2016. "Manor will make a big step up and not only because of the engine," said Wolff, who helped secure a drive at the Banbury-based team for Mercedes junior driver Pascal Wehrlein. "There is a good bunch of people coming together: impressive individuals, with the right budget and right attitude, and Pascal in the car. "I have confidence that the car and driver will have highlights and be a solid midfield runner."
