I think post 36 puts the 68mpg claims into a better context. Had the full mpg figures shown in that post been posted originally then the collective eyebrow may not have been raised. The 'What Car' 0-60 figures for the A3 140 are 9.5secs. 7.6 for the 120d and 7.0 for the 123d. It is quite possible the 120 that was driven was defective. That difference in measured performance would unquestionably be noticable. As K-Dash knows what he felt when he drove the 120d then a defect is the only realistic answer.
