McLaren have revealed a change to the colour scheme of their cars ahead of this weekend’s Spanish Grand Prix.

The Woking-based team have endured a torrid start to 2015 and remain without a Formula One World Championship point as Jenson Button and Fernando Alonso struggle to make the most of a car down on power compared to the rest of the field.

But the team are hopeful of making a step forward in Barcelona with improvements coming from both chassis and the Honda power unit.

And now the team have unveiled a new look, with a grey and orange livery replacing the silver – a mark of McLaren since 1997.

The predominantly silver design replaced the famous red and white livery of McLaren’s glory years when the likes of Ayrton Senna and Alain Prost raced for the team.

McLaren chairman Ron Dennis had said before the start of the season that the silver look could be replaced at some point during the year – suggesting a new sponsor could see an alteration.

Alonso and Button will both run in the new-look cars for the first time in tomorrow’s first practice session at the Circuit de Catalunya – the scene of a pre-season testing crash for Spaniard Alonso which ruled him out of the season-opening race in Australia.
