Citing the multi-year deal, Whitmarsh remarked at last weekend's Hungarian Grand Prix, "It's a pure Formula 1 contract, but we've already been looking at automotive technology and we're sharing that very openly. Our road car strategy at the moment has no other automotive partner and Honda would be a good place to collaborate."
Still, we wouldn't count on seeing a McLaren-Honda road car in the near future. According to Autocar, McLaren's road-car division is already tied up working on a rival for the Porsche 911, called the P13.
Whitmarsh's rhetoric was echoed by a joint statement from the two manufacturers:
"On 16 May 2013, Honda announced its decision to participate in Formula 1 from the 2015 season, under a joint project with McLaren. This has led to a full, open and productive working relationship with McLaren. As Martin Whitmarsh has stated, many ideas have been discussed between McLaren and Honda colleagues.
However, we both know how challenging it is to win in Formula 1, and we need to be 100 per cent committed to that task. Therefore, at this stage, all our focus is towards the development of the 2015 Formula 1 car and powertrain, and there are no plans for collaboration on other projects at this moment."
