2002
The 2002 season began as usual with the Monte Carlo Rally, and Rovanperä competed in a privateer Bozian Racing run Peugeot 206 WRC. He retired on the 7th stage with broken steering after an off; Tommi Mäkinen won the race in front of a penalised Sébastien Loeb, while Carlos Sainz finished third. The second rally was in Sweden, where Rovanperä returned in the official factory-entered Peugeot 206 WRC, and he finished the rally in second place, 1'24" behind team mate Marcus Grönholm, despite winning two stages and leading the rally from Stages 3 to 14.
The next two rallies were Tour de Corse and Rally de Cataluñya, both on tarmac, where Rovanperä competed for the Bozian-run team; on both rallies, he failed to score, finishing 11th in Corsica and 7th in Spain, on a surface he traditionally struggled on.
The next rally took place on the island of Cyprus, where heavy rain made conditions treacherous. Rovanperä drove the official Peugeot works car, finishing 4th and winning 1 stage. The rally was won again by his teammate Grönholm.
The WRC circus moved then to Argentina, where Peugeot had a dismal rally, Rovanperä retired after engine problems on S.S.10, Gronhölm and Burns took first and second, but were both disqualified a few days later due to an illegal flywheel and illegal servicing respectively; so Sainz won the rally from Petter Solberg.
In Greece, on a very hot and rough surface, Rovanperä finished 4th, winning 1 stage. The rally winner was Colin McRae.
The "World's toughest Rally", the Safari Rally, gifted Rovanperä with a second place, 2'50" behind the winner Colin McRae, in a rally that forced many of the drivers to retire.
In his home race at Finland, Harri had what was possibly his strongest rally of the season, seizing the lead on the 12th stage, but on the next stage he crashed and a front suspension part was badly damaged, forcing him to retire. The rally was won by teammate and compatriot Grönholm for the third year running.
In Germany, a new rally event in the WRC, Rovanperä drove an official car, as regular tarmac expert Gilles Panizzi was withdrawn from the event due to a shoulder injury he sustained while carrying out DIY at his home. However, Rovanperä was forced to retire after a very difficult rally, which saw the first victory of Sébastien Loeb in a Citroën Xsara.
In San Remo, Rovanperä returned to the Bozian team, but on asphalt the Finnish driver struggled and finished ninth, whilst Gilles Panizzi took a stunning win after his shoulder injury just three weeks before.
Rovanperä drove a near-faultless rally in New Zealand despite a hydraulic problem, finishing second, 3'50" behind Gronholm, who clinched his second WRC title.
The championship continued in the southern hemisphere with Rally Australia, and Rovanperä finished in second place again behind his team mate Grönholm, but this time only 57" behind, and winning 8 stages of the rally.
The season came to an end in the forests of Wales, where Rovanperä finished 7th after a race full of mistakes.
Rovanperä ended 2002 in 7th overall with 30 points, 47 behind teammate Gronholm, but only 7 behind runner-up Petter Solberg.
