I've wasted nearly 11 months driving my up like a diesel. That is, changing up early and keeping engine speeds low. A number of people on the forum have been saying if you want performance USE THE GEARS DUMMY! I've just started doing that. I don't redline the car - i probably max at 5K rpm and try to keep the engine at 3K which is when max torque arrives - same with both up engines. What a revelation!! I had my move up flying along the twisty, hilly roads in the Forest of Dean yesterday with two passengers and some luggage too. When i first checked my fuel consumption after the more spirited driving started about a month ago it was just 1.2 mpg worse. A well worth while trade off! And to think i got close to trading it in for a Polo just because i didn't know how to drive it!
