Hamilton: Coming from a McLaren you definitely notice the difference 7 February, 2013 Lewis Hamilton walks away after crashing at Jerez Lewis Hamilton had a forgettable debut for Mercedes at Jerez, despite going quickly while on track, he only lasted 15 laps before brake failure saw him end up in the wall, after which he lamented the lack of grip in the Silver Arrows compared to the McLaren he drove last year. Lewis Hamilton Mercedes W04 On his first official day of running after switching from McLaren for 2013, the British driver skidded over the gravel at full speed and thumped into the barriers head-first. “If I had turned the car around, the whole side of the car would have been broken,” the Briton is quoted by Auto Motor und Sport.
