"it's the evolution of the piss poor Lotus F1 car that Renault bought a few years ago."
Yep piss poor Lotus F1 team, in the financial sense only. They couldn't afford to keep Raikkonen for the whole of 2014, but in 2013.
Lotus finished 4th in constructors championship 2013, and Raikkonen won in Australia
Then they started running out of money for 2014 and 15 and were bought by Renault. How are Renault/Microsoft doing these days? Last year 9th, this year 7th so far.
