The first pre-season test is now over and Ferrari have emerged as a potential title challenger with Kimi Raikkonen topping the combined times, whilst Ferrari power locked out three of the top five positions.
However testing is exactly that and nobody knows what each other is doing, therefore it’s unwise to make assumptions for the year ahead by simply looking at times.
Reliability is a more accurate indicator, and by the looks of things, Mercedes have made a big leap forward with a combined mileage of 1,416 miles, whilst its engine covered 2,703 miles. Quite a significant amount of running compared to Honda at just 217 miles.
