Honda has revealed the “heart” of its Civic WTCC racing car for the FIA World Touring Car Championship. The new HR412E, a completely bespoke 1.6-L, four-cylinder direct injection turbocharged petrol engine, conforms to all FIA regulations for the WTCC and passed all initial tests upon delivery to the Honda Racing Team JAS workshop in Milan. It was developed at Honda's R&D center in Tochigi, Japan. “In the continuous technological development of an internal-combustion engine, the thermal efficiency is the essential key for improvement. And a race engine is not an exception,” said Daisuke Horiuchi, the WTCC Development Project Leader at Honda R&D. “This HR412E was born from such thought process: aiming for higher efficiency.” Honda plans to use the HR412E in the FIA World Touring Car Championship as early as this season, with ex-Formula One driver Tiago Monteiro behind the wheel. "We believe the innovations that have led to this revolutionary engine will also lead to benefits beyond the race track, helping us to further increase the efficiency of our road engine cars," said Horiuchi.
