McLaren technical director Tim Goss has confirmed Honda's 2017 Formula One engine will feature revised architecture and an altered layout, in a bid to boost the team's prospects for next season.
The Japanese manufacturer aims to continue its push forward with McLaren, following its return to the sport with the Woking-based outfit in 2015. McLaren finished a lowly ninth that year, before making a steady improvement in 2016 -- in which the team more than doubled its points tally from the previous season with sixth place overall in the constructors' standings.
Having struggled for much of the past two seasons with its dubbed 'size-zero' package concept, Honda has now implemented an architecture redesign for its V6 power unit based on the lessons learned. Radical changes are allowed following the scrapping of F1's engine development token system, which limited the amount of modifications teams could make.
"The token system that was applied to engine development for the past few seasons has been discontinued," Goss explained in an interview on the McLaren website. "For 2017, the Honda engine architecture and layout have been altered to serve both for performance and packaging needs."
"The new power unit takes much of the learning from the past two seasons, but has been specifically redesigned for this season."
Goss believes F1's new aero regulation overhaul for 2017 presents McLaren with an opportunity to make up significant ground on its rivals.
"Let's be clear, we're looking at some huge regulatory changes ahead of the 2017 season," Goss said. "We've had bigger changes in the past -- the change between 1982 and '83 from ground-effect to flat floors, for example, which had a massive impact on performance. But this season's changes rank as some of the most significant we've ever had in the sport.
"That's likely to change the competition order -- because it's such a big disturbance. Historically, that has changed the order -- but then what normally happens is that the best, and most well-equipped, teams tend to rise to the top again."
