Tommi Mäkinen and Kaj Lindström in action, Wales Rally GB 2003.
THE SUBARU WORLD RALLY TEAM ENTERED THE 2003 WORLD RALLY CHAMPIONSHIP SEASON WITH FORMER DRIVERS’ CHAMPION TOMMI MÄKINEN AND YOUNG PETTER SOLBERG CAMPAIGNING RALLY CARS BASED ON THE NEW 2003 IMPREZA WRX.
Ten years after the Subaru World Rally Team (SWRT) debuted the Impreza model in the World Rally Championship (WRC), it started the season with new Impreza WRC2003 rally cars. Even though SWRT had shown promise during the 2002 season, a series of unfortunate circumstances relegated Subaru to 3rd place in the Manufacturers’ Championship and Petter Solberg to 2nd in the Drivers’ Championship.

SWRT had a head start because it was the only team to have its 2003 rally cars ready for the season’s first rally – Rallye Automobile Monte-Carlo. Although neither Petter Solberg/Phil Mills nor Tommi Mäkinen/Kaj Lindström finished the first event, they scraped and clawed throughout the year to set up the season finale at the Wales Rally GB. By then, Solberg/Mills had won three WRC rallies.
Heading into the Wales Rally GB, four drivers were in contention for the Drivers’ Championship – Sébastien Loeb and Carlos Sainz, tied with 63 points; Petter Solberg with 62 points; and Richard Burns with 58 points. But Burns was hospitalized prior to the event and didn’t participate.
Solberg was determined, winning the first Super Special stage. Loeb countered by winning the second stage. Sainz, Loeb’s teammate, crashed during the next stage, leaving the rally – and the drivers’ title – to be contested by Solberg and Loeb. During the rally’s Leg 2, Solberg set fastest time for each stage. On the third day, despite sustaining damage on a later stage, Solberg was fastest on the last stage to clinch the event and the title. Petter Solberg instantly became a national hero in his native Norway.
Thanks to points-paying drives by Solberg/Mills and Mäkinen/Lindström throughout the season, Subaru placed 3rd in the Manufacturers’ Championship.
Rally Finland in August marked the 10th anniversary of WRC competition for the Subaru Impreza model. During those 10 years, the Impreza was the most competitive car in the WRC.
SWRT’s Subaru Impreza WRC2003 was based on the new lighter and more rigid Impreza body. It was the result of an integrated design process between Subaru and Prodrive. The rally version featured body modifications and aerodynamic enhancements in the front bumper and rear wing. The WRC2003’s upgraded engine benefitted from greater torque at low and medium engine speeds and improved pickup capability.
The car received additional modifications throughout the season, notably to its suspension system.
