Heidfeld revealed Thursday in Budapest that Renault is not even planned to run it this weekend, as his fingers at the moment.

"We are planning to, as I know, use the direct version here," Heidfeld said Thursday. "We are still investigating the one back." "We are going to see when we touch again, but surely we are looking at."

Despite Renault decide against using the system oriented, Heidfeld said the car performed better with it.

"General upgrades work." Our performance was clearly better at Silverstone, "he said."

The German driver said Renault some improvements this weekend, with a major upgrade planned for the Grand Prize of Belgium.

"Only small pieces of the aero side", said about the updates this weekend. "We have recently seen a lot of improvement in the wind tunnel, but we do not have many of the parties here unfortunately." "We have a big update for Spa."
