Kova is 20, not 21. At least, Lotus have been running him in the tests with 20 on the car, and Trulli with 21.
#20 – Heikki Kovalainen Golf-obssessed Finn Heikki Kovalainen (check his Twitter account if you don’t believe me) has been in Formula One for 4 years now. Having started with Renault, he swapped with Alonso to go into McLaren, before taking the brave step of joining new team Lotus Racing. He’s not done badly, having outperformed his teammate Jarno Trulli in four of the five races when they both finished, despite typically qualifying slightly lower down the grid. His other awesome record is that he was the 100th driver to win a Grand Prix.
But before that he had the lower series to compete in, including the first ever season of GP2 where he came second to Mercedes’ Nico Rosberg. In 2004 he won his only series championship so far – the World Series by Nissan. Despite starting in the lowest-numbered team on the grid, he had 10 poles, 8 fastest laps and 6 wins, including five races in which he had all three. Other opponents included former Jordan driver Tiago Monteiro (2nd, though his only F1 podium was at the 2005 US GP), Narain Karthikeyan (6th, though he won two races) and Karun Chandhok (16th, though he only competed in two rounds). This brought his team to finish first in the championship, and earned most of the team’s points himself: 186 out of 245, with 32 more points than Tiago Monteiro.
