as far as fuel efficiency is concerned I have no complaints.... I get approx 7.5 in city. varies between 7.2 and 7.8.....I think its very good for a vehicle of this size and weight. even much smaller older cars with traditional auto do 8.5-9.5 in my kind of usage so 15-20% higher fuel use is totally justified.
These days I'm training myself to switch off the engine when the car is still, however with summers arriving it can't be done due to A/C use
