The 25-year-old Pole has made a strong start at the Regie having joined them from BMW Sauber and currently stands seventh in the standings – comfortably the highest-placed driver outside the ‘big four’ of Ferrari, McLaren, Red Bull and Mercedes GP.
Kubica, who finished second behind Jenson Button in Australia, has been a galvanising presence at Renault, whose 2009 season was marred by poor results and the fallout from the ‘Crashgate’ scandal.
As a result, the French manufacturer considered withdrawing from F1 late last year, before opting to sell a 75 per cent stake in its team to Lopez’s Genii Capital investment firm.
By their own admission, Renault have performed above expectations this season with Lopez singing the praises of his star driver, who himself struggled last year having been a title contender in 2008.
“I knew Robert from BMW, even before he was an F1 driver there,” Lopez told SPEEDtv.com. “I’m a very strong believer that on pure speed and character he’s one of the few that deserves a world championship at some time.”
