I drive an unmodified Golf GTI. Sticking to speed limits, the difference between driving aggressively in Sport mode and driving normally in normal is about 20mpg. The difference between driving normally in Normal mode and more fuel consciously is probably another 10 mpg on top of that (on a 3 hr trip, no motorway i saw roughly 8-10 mpg driving aggressively and close to 38 when driving normally. Motorway driving is a little closer, but I live in Scotland so motorway isn't usually an option)
