Hûlkenberg impressed with the stability of the Lotus

Today Roman Grosjean held a race simulation tests in Barcelona and in the evening said that it was very difficult to do so. The Frenchman watched and rivals, because as the distance you can estimate the amount of fuel on board. Sauber driver Nick Hûlkenberg evening spoke about his impressions.
Nico Hûlkenberg: when the amount of fuel in the tanks of vehicles has declined, the rate of Lotus Grosjean was very good, and with rubber this machine works very neatly. However, if I remember correctly, a year ago at the winter tests, they were fast and stable.
On my machine the tires wear out more, but I'm not too worried about this. Next week we will continue with the tests. Perhaps the weather will be warmer and the condition of the road will improve. While I worked for four days, and everything went without problems, now you need to work just as well for two days next week. "
