After Ferrari unveiled their F160 last week, F1 teams Renault, Sauber and Lotus have also unveiled their new cars for 2011 season.
Renault ended last season at 5th in the Constructors championship and their Polish driver Robert Kubica had posed problems to some of the bigger teams. On the new car, he said, It has been a long break, after a good last year so I'm really looking forward to test the new car, a new baby for the team and we hope it will be a good one. It looks good, but what is most important is that it goes quick, so let's hope we have a competitive car.
Renault's technical director James Allison said, Words like 'aggressive' and 'innovative' are very much in vogue in Formula 1 at the moment, but where the R31 is concerned we feel those adjectives are appropriate.
It's true to say that the car has been designed in an ambitious manner and a quick glance at the layout will confirm that its entire concept differs considerably, not just from last year's car, but from any car this team has ever produced.
One of the things to look out for in the 2011 season will be the rivalry between Team Lotus and Renault. Lotus' driver Jarno Trulli said, Last year we aimed to finish the race. This year we aim to finish in the points and with this package it should be achievable.
Lotus' latest car is named the T128 -a continuation of history and it succeeds last year's T127.
This year's car is a much more contemporary design, said Lotus technical director Mike Gascoyne. The car really will be a midfield runner. It's a modern F1 car I'm very confident it is a big step up and it's the start of a process that takes Team Lotus back to the front of the grid.
There's been almost no carry-over of parts for the 2011 car, whereas normally you'd have a substantial carry-over and the chance to optimize last year's parts, added Gascoyne.
It has a much more current feel about it. And it's the basis of our cars for the future.
BMW Sauber, who finished eighth in the constructors championship with 44 points last season, will continue with Japan's Kamui Kobayashi for their new car Sauber-Ferrari C30.
Their owner Peter Sauber said the team would aim to score regular points and mix it with the teams in the middle. He said, We want to finish in the points regularly and clearly improve our position in the world championship.2010 marked the 41st year of our company history and one of the most difficult. But we managed to overcome these difficulties in the second half of the season.
We implemented some well-considered structural changes. The appointment of James Key as technical director already bore fruit last season, and he is now in charge of development of the Sauber-Ferrari C30.
At the same time, we have managed to secure our business foundation for the 2011 season. In these economically straitened times that is something we can be proud of too.
