Auto GP World Series champion Adrian Quaife-Hobbs has confirmed he will drive for GP2 teams Addax and Arden during this year's end-of-season tests in Spain.
The Briton will sample Addax machinery in Barcelona on October 30-31, before making his maiden visit to Jerez to drive for Arden on November 22-23.
The outings are part of preparations for a planned step up to GP2 in 2013.
"GP2 is a series with relatively constricted testing, so it is important to do all the test days available," said Quaife-Hobbs, who is aware that the last two GP2 champions, Pastor Maldonado and Davide Valsecchi, have claimed the title in their respective fourth and fifth seasons in the category.
"It appears to be a series where experienced drivers go well," offered Quaife-Hobbs. "I am sure you can jump in and be reasonably competitive but experience seems to count for that last bit of performance."
Quaife-Hobbs will return to Barcelona on December 6-7, where he will conduct the debut outing of the 2013 Auto GP car at the championship's collective test.
"The Auto GP and GP2 cars are similar in straightline speed, but obviously there's more downforce in GP2 and the tyres behave differently," continued Quaife-Hobbs.
"But in Auto GP you learn power and tyre management, something that is becoming crucial in GP2 and F1 and that you don't experience elsewhere."
