Renault's Nico Hulkenberg believes that the Hungaroring is the best track for Kubica to be tested at. After the Hungarian Grand Prix this weekend, Kubica will get a taste of the 2017 cars for the first time, while Renault will assess his capabilities and then look towards a possible full-time return.
Kubica has already taken part in two private tests with the French manufacturer, driving the Lotus E20 around Valencia and Paul Ricard. With the Hungaroring being a very technical circuit, Hulkenberg believes it will truly show what the Pole can do.
"The Hungaroring is one of the most strenuous tracks, because there is only one straight on which to relax," the German told Auto Motor und Sport. "After the race weekend there's a lot of rubber on the track too, which means maximum grip. Anyone who passes that test can also drive a Grand Prix."
There are also suggestions that Kubica could take up a race seat as early as the Belgian Grand Prix if he impresses in the test. He last raced for Renault in 2010, pulling out of the 2011 season due to a major injury suffered while rallying.
