Sometime between the Jan 10 and Sep 11 brochures the specification of the S5 changed from a 0-60 of 5.4 to 5.1 secs and urban economy improved from 20.9 to 26.4 mpg yet the power stayed at 333 PS.
Was it due to a new engine with exactly the same PS or could a remap do the same if I bought an older S5?
