What is a BONDI engine?

What is best? Smaller engine + heavy foot, or larger engine with normal foot?

• I drive a 2.2 Litre 140 HP Saturn Ion 2, and I drive with a heavy foot because it is only 140 hp and is not powerful enough to accelerate the way I would like "easily". I understand this is bad, as it is harder on the engine, and uses more gas. Would I actually SAVE (use less) gas by having a vehicle with a bigger engine, like 170 HP? I wouldn't have to drive with a heavy foot because the engine would more naturally accelerate easier, and engine load would be less as it is more capable. So which is better for saving money on gas? Driving a small engine hard, or a bigger engine normally? Also would I basically burn out a car like Chev Cruze with it's 1.4 Litre Turbo 138 HP Engine faster than an engine line Ford Fusion 170 HP 2.5 litre? I drive a standard, rev match the transmission when shifting, and take care of my vehicles other than wish my 140 hp Saturn had more acceleration capability.

• Answer:

  More fuel is used during acceleration than at any other time in the drive cycle. If you want fuel economy the golden rules are, keep the vehicle as light as possible, small engine, keep the speed down, don't accelerate hard, streamline the shape of the body. But this makes the whole driving experience so boring, you end up with a small slow car with no cred. How will you impress the girls with that? It's a trade off, testosterone against economy and for you economy will loose until you reach 50 years old. Just have the car you want and go easy on the right boot.
