A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
Perez is a star for dragging this car to points in china. He somehow managed to save the tyres enough to make the strategy work. This car seems to be a step back from last year. It just didn't keep up with the others in terms of development.
Hard to say what the weaknesses are, as they may be many.
