Lotus has become the first F1 team to unveil its 2013 contender as it launhced the E21 at its factory in Enstone. The team launched the car via its YouTube channel, with the new car still featuring the stepped nose and also featuring the Coanda-effect exhausts it introduced towards the end of 2012. Technical director James Allison said that the car may look similar to its predecessor but that a number of features beneath the bodywork are different to the E20.
Kimi Räikkönen - 2012 was a good start, let’s see what we can do in 2013:
"I’m feeling pretty good. Last year was my return to Formula 1 and it went pretty well. This year will be my second with Lotus F1 Team and my eleventh season overall in Formula 1 so I’ve got a pretty good idea of what to expect. I’m sure it will be an exciting season and I’m sure there’ll be lots to talk about. For me, I will continue to do the best I can. Let’s see how good our car is, and how good the cars of the opposition are too. I’ve not driven the E21 yet so it’s difficult to say what could or could not be possible. We know we had a good car last season, but everyone is working hard to make the best car. I will be working with the team to help get the car as strong as we can, then in Melbourne we’ll have our first taste of results. It’s a long season from there. 2012 was a good start, so let’s see what we can do in 2013."
