Fernando Alonso announced last year that he was moving away from Formula 1, opting to race in the World Endurance Championship and Indy500 as progress had not been what he had hoped with McLaren.
he Woking team took on Carlos Sainz from Renault and promoted rookie Lando Norris into the other seat.
Brown feels that, although neither have the experience and success of Alonso, his drivers will be able to show the full potential of the car and the progress that has been made.
Brown said: "Carlos has a lot of experience and it is good that he has been in a couple of different teams,” (motorsport.com).
"Lando has proven that he is extremely quick, so I think as far as ultimate performance of how fast is our race car, I think those drivers will get the most out of the race car. They will be able to tell us."
"Someone like Lando does not have the experience of someone like Fernando, nor the type of feedback, and it will take some time for him to develop, but for Carlos it is his fifth year in the sport, so we are comfortable with our drivers."
Norris has ben part of McLaren for quite a long time being their junior programme driver, having had help from the team and Alonso. Sainz on the other hand is more the newcomer and Brown has been impressed with the Spaniard so far.
"He is very dedicated, asks a lot of questions, and is very mature given his age but I think that is because of how long he has been in F1."
"Then, as a driver, from what we have seen so far, we are very impressed. He is aggressive, he is very engaged with the engineering team, and he wants to know what is happening."
