Hi John,

I'm assuming you're talking about the current version. If so then there's barely any difference. Citroen quotes the same 74mpg figure for both models (which means you'll probably get about 50mpg in real life) and there's only 1g/km between them. The only significant difference is that the 120hp model does the 0-100km/h sprint in 12.2 seconds instead of 13.8 seconds for the 100hp. To be honest, unless your daily drive involves half a dozen Traffic Light Grand Prix then you're probably unlikely to notice any difference.
