The departure of technical director James Key was seen as a pre-season blow but the Swiss team are solidly professional and have been going about their business in testing with typical precision. The car looks a tidy solution to the rule changes and has set some impressive times.

Perez now has a year's experience under his belt and will have grown in confidence while Kobayashi knows how to thrill. Sauber's biggest challenge could be developing the car over the year due to tight budgets.
