Spa-Francorchamps, Belgium - Lewis Hamilton said Ferrari had 'trick things going on' with their car after Sebastian Vettel won Sunday's Belgian Grand Prix but emphasised he was not accusing his Formula One rivals of doing anything illegal.
The championship leader's comments aroused immediate interest with the Mercedes driver, who finished second at Spa and saw his overall lead cut to 17 points, facing questions afterwards.
"We all have trick things going on our cars," said the Briton, who had started on pole position but was swiftly overtaken by Vettel - who then raced untroubled and finished 11 seconds clear.
"Trick is just a word for something special, I guess," added Hamilton.
Asked whether he felt Ferrari were doing something illegal, Hamilton initially said he had no idea what was on the Italian team's car so could not say either way.
