Lotus E20 uncovered at the team's Enstone factory 5 February, 2012 Lotus E20 Feb.5 (Lotus) The car which Kimi Raikkonen will drive on his return to Formula 1 – the Lotus E20 – was unveiled to the world today at the team’s headquarters. Kimi Raikkonen and Romain Grosjean unveil the Lotus E20 This is the 20th F1 car produced at the Enstone factory, hence the monicker – E20. Raikkonen and team mate Romain Grosjean did the honours of taking the wraps off the black and gold E20 which, like the majority of recently unveiled cars, features a steeped up section between the cockpit and the front nose area. Raikkonen said: “I think these people know how to build a good [racing] car. Even the biggest teams cannot produce a winning car every year. They’re very capable people and they have a good feeling about things. They’re pushing hard so hopefully we will get good results.” Asked if he had any apprehension coming back to F1 which he abandoned two years ago, the 2007 world champion answered: “Not really. It will be something slightly different to what it used to be when I was in F1 before. A different team and different regulations, but everybody’s different. For some people it’s more difficult to get used to new stuff.” Lotus E20 “It depends a lot on the car. If you have a good car it makes your life easier than if you have an average car. I was pretty happy after the first test we did two weeks ago. It felt pretty normal already. I think it will be okay, but before the first race it’s really difficult to say still. We will wait and see, but I am happy with how things are going,” added Raikkonen. Team principal Eric Boullier gave notice that the team’s 2012 challenger features innovations which were ‘under the hood’, saying “It is true that the team’s reputation is good in terms of innovation and we brought through the last years some nice ones, and let’s say some more delicate ones, but definitely we have some this year.” Technical specifications Chassis Moulded carbon fibre and aluminium honeycomb composite monocoque, manufactured by Lotus F1 Team and designed for maximum strength with minimum weight.
