“There are some things we can’t turn the clock back on,” Ross Brawn said.
Ross Brawn: “We’ve got a very, very impressive engine.”
Ross Brawn: “The cars have got heavier, we’d all love the cars to be lighter.”
Ross Brawn: “A nice little normally-aspirated engine.”
Ross Brawn: “I can’t remember the weight now, six hundred and something.”
