“This Aston Martin team is clearly applying the energy and commitment to win, and it is therefore one of the most exciting teams in Formula 1 today,” said Alonso in a statement.
“I have known Lawrence and Lance for many years and it is very obvious that they have the ambition and passion to succeed in Formula 1. I have watched as the team has systematically attracted great people with winning pedigrees, and I have become aware of the huge commitment to new facilities and resources at Silverstone.
“No one in Formula 1 today is demonstrating a greater vision and absolute commitment to winning, and that makes it a really exciting opportunity for me. I still have the hunger and ambition to fight to be at the front, and I want to be part of an organisation that is committed to learn, develop and succeed.
“The passion and desire to perform that I have witnessed convince me to maintain my enjoyment and commitment to the sport.
“I intend to win again in this sport and therefore I have to take the opportunities that feel right to me.”
