Niki Lauda has said that the key to winning the Formula 1 title will be producing a reliable car as the team adjust to new engine regulations.
The Austrian, who won the world championship in 1975, 1977 and 1984, believes that having more speed than your rivals may not dictate who comes out on top at the end of the season.
He told Ferrari's official website: "The challenge for the engine people is enormous.
"Then there is the new car and installing the car and engine in a way that you are reliable – this is the biggest challenge.
"Whoever will have the least failures this year will be world champion."
Lauda is currently the non-executive president of German constructor Mercedes.
