Sergio Perez was quickest in Barcelona on Wednesday, but he also admitted that Jenson Button still rules the McLaren roost.
Asked by Spain’s AS newspaper to rate his adaptation from Sauber to McLaren, the young Mexican answered: “From zero to ten, I would say it is a 6 or a 7.” Perez said the “management style and philosophy” of Woking based McLaren and the Swiss team Sauber is fundamentally different, adding that his experienced teammate Button has the advantage of having being involved in the development of the new MP4-28 car.
At the 12-hour mark, nine different leaders had paced the field with the defending race and series champion No. 01 TELMEX BMW/Riley Daytona Prototype of Chip Ganassi Racing and its sister No. 02 Target BMW/Riley dominating large portions.
