Robert Kubica has done some handy mileage in the modern generation Formula 1 cars. after several years marginalised by injuries suffered during a freak rally accident, and he suggests that current cars are far too heavy compared to the versions he drove in 2011.
Speaking after his stint in the Williams during testing at the Circuit de Barcelona-Catalunya, Kubica told reporters, "The first thing I noticed was the weight," he told Auto Motor und Sport. "The cars are now at least 60 kilograms too heavy, in slow corners, it feels like a bus."
Weight limits have changed since Kubica last tested as a grand prix driver in Spain during the beginning of 2011.
"They weighed 605 kilograms and had 50 kilos of ballast on board. The tyres also had a shorter life so you could attack the whole race," recalled the Pole who is Williams reserve driver this season.
"From the outside, it looks like the drivers are all on their own. That's because everyone is keeping their distance because of overheating."
"It's impossible today, you have to manage everything. Bring down the weight, then many problems will resolve themselves," ventured Kubica.
He also questioned the need for pit-to-driver communications, "The drivers today may have gotten lazy. I see no reason why a good driver needs any instructions from the pits."
