Unless you’ve been stuck under a rock for the past 48 hours, you’ll know that Lotus have unveiled their car with which they hope to challenge for race wins in 2013, the E21.

We’ve sourced photos not only from the launch, but also of it’s predeccesor, the Lotus E20, which Kimi Raikkonen won the Abu Dhabi Grand Prix in last season. In putting them side by side, we can clearly see there are differences – but the real question is, what will the car look like when testing gets underway in Jerez?
