Honda has 'redesigned' power unit - McLaren

7 January 2017 – McLaren Technical Director Tim Goss has revealed that Honda has redesigned its power unit layout for 2017, following the FIA's decision to drop the token-based development system.

Formula 1 introduced a token system under revised regulations in 2014, in a bid to control development costs, in which different elements of a power unit were weighted.

Manufacturers were permitted to make only limited changes, based on available tokens, but the unpopular system has now been abandoned for the 2017 campaign.

The use of tokens hindered Honda's progress since its return to Formula 1 with McLaren in 2015 in which it adopted a tightly-packaged concept for its power unit, dubbed 'size zero'.

McLaren finished only ninth in the Constructors' Championship during its first reunion year with Honda, while last season it placed sixth overall.

"The token system that was applied to engine development for the past few seasons has been discontinued," Goss explained in an interview with McLaren's official 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 added that the increased downforce levels expected from 2017's Formula 1 cars will lead to some turns no longer being regarded as corners.

"We'll no longer classify some corners as 'corners'," he commented.

"What we mean by that is that engineers define a corner as a point on the track where the driver has to lift and essentially drive and handle the car through it.

"If he's going around a bend, and his foot is flat to the floor on the accelerator, we class that as a straight.

"As the new cars will be going faster, some of 2016's 'corners' will be classified as 'straights'."
