Oct.13 (GMM) Timo Glock has lamented an apparent lack of respect for F1's smallest teams.
According to Germany's Auto Motor und Sport, engine supplier Renault has said it is 'not interested' in supplying its new turbo V6 to backmarkers Marussia and HRT in 2014.
"It is a pity that the smaller teams are not always thought about in the same way.
"We are apparently not as respected as the others," said Glock, who moved to 2010 startup Marussia - formerly Virgin - when the Japanese giant Toyota pulled out of F1 in 2009.
Marussia had a troubled preparation for the 2012 season, but chief engineer David Greenwood insists next year will be a different story.
"We worked a little longer than planned on the current car, but we are now switching to the 2013 model," he said in Korea.
"The first chassis is already being worked on and the guys in the factory are now beginning the first part of the crash tests.
"So we are in a much better position than last year."
Marussia has a technical collaboration with McLaren, and in 2013 will use Williams' KERS system.
