Cape Town - Ex-F1 driver Pedro de la Rosa believes Mercedes will have an aerodynamic edge this season after getting a head-start on their rivals in the wind tunnel.
Mercedes strolled to a third consecutive Drivers' Championship and Constructors' Championship last season, and de la Rosa believes their clear dominance over the rest of the field means they were able to quickly turn their attention into preparing for the 2017 campaign.
De la Rosa also weighed in on the ongoing debate as to whether Valtteri Bottas is capable of providing Lewis Hamilton with strong competition.
"It's always easier when you drive a very good car!
"He will fit perfectly into the team – he's a hard worker, he's not political, he will do his own thing, he won't be bothered by how fast or slow Lewis is.
