Force India has signed a long term agreement with Mercedes-Benz, the team has announced.
Mercedes-Benz will supply the Silverstone based team with a complete Power Unit - including the Energy Recovery System - under the new regulations, which come into effect from the start of next season.
Force India has used Mercedes' engines since the start of 2009.
"With new powertrain regulations being introduced next year, I can’t think of a better partner to work with as Formula One enters a new and exciting era," said team principal Vijay Mallya.
"The agreement gives us the long-term stability we require and will enable us to continue our journey towards the front of the Formula One grid."
Mercedes' executive director Toto Wolff added "It is a significant milestone to announce our first long-term agreement for powertrain supply under the 2014 regulations."
"Force India was our first genuine customer in Formula One back in 2009 and we are delighted to enter an expanded, long-term relationship with them from 2014 onwards. This long-term agreement offers excellent value in terms of the balance between price and performance."
