In fact, Red Bull manager Dr Helmut Marko claims the single seater steered by Sergio Perez and Kamui Kobayashi this year is "perhaps the best car in the field".
However, the Ferrari-powered car has been on the podium just twice in 2012 so far, which has attracted criticism of the young driver duo.
McLaren's Jenson Button said: "It's not Perez who is the 'tyre whisperer', it's the car.
"If I was to drive my car as he drives his, then our tyres would wear out very quickly."
Peter Sauber recently described Sauber's 2012 season so far as a "roller coaster ride", although he did not specifically criticise Perez or Kobayashi.
He told Blick: "We have a very fast car that works very well on almost every circuit. We have the speed to win.
"We could have scored a lot more points."
With nine races to go, Hinwil based Sauber is ranked sixth of the 12 teams in the constructors' championship.
