Motor racing-McLaren waiting for sponsors before livery change

Feb 1 (Reuters) - McLaren will change the livery of their new Formula One car when there are commercial reasons for doing so, group chief executive Ron Dennis said on Sunday after the MP4-30 made its track debut in southern Spain. The former champions have lacked a title sponsor since telecoms giant Vodafone withdrew at the end of 2013 and they turned up for the first pre-season test at Jerez with unbranded trucks and a car painted silver, black and red. The livery seen so far has not impressed many fans, who had hoped for something bolder at the start of a new partnership with Honda, on social media. Dennis told reporters in Jerez that there had been discussions within the team, who have not won a race since 2012, but they would not change without reason. "This is the livery of McLaren," he said. "It has always been a combination of these colours and it will only change for commercial reasons. "It will change. But I'm not going to say when."
