One thing I am sure of - there will not be 0.4s between the two cars 0-60mph, not with a 10% taller final drive. (2012=4.9s, 2013=4.5s in the specs.)

The 2013 should be a bit faster given the engine output, but 10% on the final drive is quite a lot. I would really like to see these two cars tested against each other. My bet - somewhere between 0.1 and 0.2 s.

Interestingly, in the local (Australian) spec, the 0-100kmh spec is given at 4.9s, the same as your 0-60 mph. But 100kmh = 62.13mph, so converted to 0-60mph, our spec says 4.7s for the 2012.
