Lotus F1 issued a short statement in which it confirmed that their 2010 car will be unveiled to the media & fans on February 12th. Although the team's technical chief Mike Gascoyne previously told the media that his team is actually ahead of schedule and that it plans to unveil the car in the first days of February, it seems the Malaysian organization needs more time to properly set up the last details of the machinery.
As stated in the press release, the 12th of February will mark the date in which Lotus will unveil their first Formula One challenger in over a decade and a half. The last Lotus car seen in F1 was the 109 model, back in 1994, which benefited from a Mugen Honda engine. 16 years later, the Lotus challenger will also use another engine partner for their F1 programme, namely British engine manufacturer Cosworth.
The Malaysian team was the first one of the newly entrants that announced their complete drivers lineup, back in December. The team's CEO Tony Fernandes confirmed Grand Prix winners Jarno Trulli and Heikki Kovalainen for the 2010 campaign, and said that his team's goal for the upcoming year is to be the best of the 4 new F1 entries.
As for their 2010 challenger, the team is yet to reveal anything more than the launch date. The official designation of the car, as well as the location where it will be unveiled, is yet to be announced by Lotus F1.
