Η Honda ακολουθεί το παράδειγμα της Ford και της Mazda και παρουσιάζει για πρώτη φορά τον twin-turbo V6 που θα χρησιμοποιηθεί από τα πρωτότυπα Daytona στο United SportsCar Championship.
O HR35TT όπως είναι η ονομασία του, είναι βασισμένος στον J35 κινητήρα παραγωγής που βρίσκουμε σε διάφορα μοντέλα, μεταξύ των οποίων και το Αμερικανικό Accord. Στην αγωνιστική του έκδοση, ο 3.5 λίτρων twin turbo V6 έχει εξοπλιστεί με ξηρό κάρτερ αλλά διατηρεί το αλουμινένιο block, τον άμεσο ψεκασμό και τους μονούς εκκεντροφόρους επικεφαλής της “πολιτικής” έκδοσης. Φυσικά, όπως γίνεται σχεδόν πάντα με τους αγωνιστικούς κινητήρες, δεν έχουν δοθεί στη δημοσιότητα συγκεκριμένα νούμερα για ιπποδύναμη και ροπή.
Ο κινητήρας θα κάνει το ντεμπούτο του με την Starworks Motorsport σε ένα Riley Gen3 πρωτότυπο στις 12 ώρες του Sebring στις 12 Μαρτίου.

Honda Performance Development Unveils 3.5-Liter Prototype Engine
02/20/2014 – SANTA CLARITA, Calif.
Starworks Motorsport to Debut HR35TT at Sebring
Latest Racing Application of Production-Based Honda V6 Engine
Two-Team HPD Effort In TUDOR United SportsCar Championship
Honda Performance Development Thursday announced a new, 3.5-liter racing application for the versatile, production-based Honda V6 engine found in a wide range of Honda/Acura passenger cars and light trucks and now raced in multiple categories worldwide.
The Honda HR35TT twin-turbocharged V6 is expected to make its TUDOR United SportsCar Championship debut at the 2014 Mobil1 12 Hours of Sebring, mounted in a Riley Gen3 prototype chassis campaigned by Starworks Motorsport.
Previously, Starworks partnered with HPD to win the LMP2 class at the 24 Hours of Le Mans and World Endurance Championship in 2012, using HPD’s ARX-03b chassis and Honda HR28TT twin-turbocharged V6, which also is derived from Honda’s J35 series of engines.
Starworks becomes the second team to utilize Honda power for the new TUDOR championship. Extreme Speed Motorsports campaigns a pair of prototype class HPD ARX-03b Hondas, after a successful initial season with the same package in the 2013 American Le Mans Series.
“This is an exciting program for HPD and our customer teams in the TUDOR United SportsCar Championship,” said Steve Eriksen, HPD Vice President and COO. “Adding Starworks, a team that achieved great success with us in 2012, in a prototype machine alongside the proven HPD-Honda combination run by Extreme Speed Motorsports provides HPD with a strong, balanced attack in the inaugural TUDOR Championship.”
“It’s a fantastic feeling to be partnering with Honda once again,” said Starworks team owner Peter Baron. “No doubt we had amazing success with HPD in 2012, but unfortunately it was only a one-year program. We have had numerous conversations over the past two years about building a Daytona Prototype motor and we’re thrilled to see it come to fruition. We absolutely love working with HPD and have been in collaboration to find a new opportunity to partner with them again. We will have our work cut out with the steep learning curve to get us to Victory Lane, but HPD brings determination and success to every program it touches. Although HPD already competes in the Prototype class, we feel this is huge step for the TUDOR series and Starworks is thrilled to be part of it.”
Starworks Motorsport has compiled an enviable record in Daytona Prototype competition, with five race victories, including back-to-back wins at Indianapolis in 2012 and 2013; and a second-place finish in the Daytona Prototype team championship in 2012, with two victories and six podium finishes. That same year, Starworks became the first American-based prototype team to win an FIA World Championship since 1968, and HPD won its first world title in WEC competition.
The HPD-developed twin-turbocharged Honda engines to be used in the TUDOR championship are both derived from the Honda J35 series of production V6 engines, and include relevant twin-turbocharger technology, along with the efficiency provided by direct fuel injection.
The HR35TT is yet another competition application of the ubiquitous J35 engine. The first, the HR28TT, was designed for LMP2 competition and won in its American Le Mans Series debut in 2011. The engine has gone on to record 24 individual race victories and three series titles in the American Le Mans Series, World Endurance Championship and European Le Mans Series Competition.
Other variants of the engine have been raced in Japan’s Autobacs SuperGT Championship, the One Lap of America competitive rally and Pikes Peak International Hillclimb.
Honda Performance Development (HPD) is the Honda performance company within North America. Located in Santa Clarita, Calif., HPD is the technical operations center for high-performance Honda racing cars and engines. The company is marking its 20th anniversary in 2013.
As an engine supplier to the IZOD IndyCar Series, Honda has scored 204 race victories in both CART and IZOD IndyCar Series competition since 1994, and powered Scott Dixon to a series-high four victories and the 2013 IZOD IndyCar Series drivers’ championship.
HPD offers a variety of race engines for track applications from prototype sports cars to karting; and showcases “fun-to-drive” products for professional, amateur and entry-level racers.

Honda Joins Daytona Prototype Ranks
- Latest racing application of production-based Honda V6 engine
- Race debut takes place at the 12 Hours of Sebring
Honda has expanded its attack on the 2014 TUDOR United SportsCar Championship, and will join the Daytona Prototype category for the first time later this month at the 62nd annual Mobil 1 Twelve Hours of Sebring.
Honda has a history of success at the Florida endurance racing classic, including LMP2 class victories in 2007, 2009, 2011, 2012 and 2013, and top-three overall race finishes in 2007 – the company’s debut in sports-car racing under the Acura Motorsports banner – and again in 2011.
Honda Performance Development (HPD), Honda’s North American racing company, has developed a new, 3.5-liter, twin-turbocharged Daytona Prototype version of the production J35 engine, the latest of several HPD racing applications for the V6 power plant found, in various forms, in a wide range of Honda and Acura passenger cars and light trucks.
“This is a great opportunity for HPD and our customer teams in the TUDOR United SportsCar Championship,” said Steve Eriksen, HPD vice president and COO. “Adding a Daytona Prototype effort alongside the proven HPD-Honda chassis and engine combination in LMP2 provides Honda with a strong and balanced attack in the inaugural TUDOR Championship.”
Honda joins Chevrolet and Ford in the Daytona Prototype manufacturer ranks and becomes the only company to field efforts in both categories that make up the new Prototype class in the TUDOR United Sports Car Championship.
Honda Enters Daytona Prototype Competition
In the companion LMP2 prototype category, HPD produces a complete chassis-engine package, including the ARX-03b chassis and Honda 2.8-liter HR28TT twin-turbo V6 engines, in competition with both Nissan and Mazda. This combination results in an impressive five-manufacturer lineup vying for Prototype honors in the 2014 TUDOR championship.
Both HPD-developed Honda engines used in the TUDOR championship are derived from the same Honda J35 series of production V6 engines and include relevant twin-turbocharger technology, along with the efficiency provided by direct fuel injection. Key production-based components that are utilized include block and heads, crankshaft, direct injection fuel system, valve train components, drive-by-wire throttle, alternator, sensors, fasteners, etc. The engine even utilizes a stock Honda oil filter.
Other variants of the engine have been raced in Japan’s Autobacs SuperGT Championship, the One Lap of America competitive rally and the Pikes Peak International Hill Climb.
The Daytona Prototype Honda Riley package will debut at Sebring fielded by Starworks Motorsport, while Extreme Speed Motorsports will continue to field a pair of HPD ARX-03b Hondas created to LMP2 specifications, continuing a partnership that began in 2013.
