Block and Gronholm will both do a full season of the Global RallyCross championship, which supports Indycar and NASCAR races as well as the X-Games in California.
They will each be driving Ford Fiestas but for different teams: Block for the Monster World Rally Team (which will also take part in three WRC events, starting from next month's Rally Mexico) and Gronholm - who won the WRC title in 2000 and 2002 - for the Best Buy Racing Olsbergs Motor Evolution team.
“I’m super stoked to be able to run such a diverse schedule this year,” said Block, who will include another Gymkhana World Tour on his programme this year. “Global RallyCross is shaping up to be a very exciting and new championship in the United States.”
The American is also relishing his WRC challenge in Mexico, New Zealand and Finland. “The WRC contains some of the best drivers in the world,” he added. “I feel privileged to be able to compete against them.”
Gronholm is the second-most successful driver in the WRC in terms of rally wins, having retired at the end of the 2007 season. He too is looking forward to some American adventures this year. “I’ve always wanted to win every time I get in a car,” he commented. “I have some unfinished business in rallycross.”
The first round of the series gets underway at Las Vegas Motor Speedway in Nevada, on April 21.
