Modern engine technology means manufacturers can extract more power from a smaller engine while improving fuel economy and reducing exhaust emissions. Smaller engines can also benefit a car’s driving characteristics because the smaller size reduces weight.
Do smaller cars use less gas?
Motorists are usually advised that smaller cars can travel more miles per gallon (mpg) than those with larger engines, making them cheaper and more environmentally friendly to run.
Why are smaller engines more efficient?
A smaller engine is also often lighter, so less overall energy is expended while driving. Reducing the number of cylinders also reduces the amount of friction in the engine, increasing the efficiency.

How do smaller engines produce more power?
Engines make power by moving air through them. A smaller engine can move more air than a larger one by having better flowing heads, turbochargers or revving much higher or any combination thereof. The more air you can move through an engine matched with proper fuel, the more power you’ll make.
Is a 2 Litre engine good?
Although plenty of 2.0-litre cars can be suitable for towing, anything above this is ideal for pulling things like heavy trailers or caravans. More power combined with more torque will give you the best experience when you’re towing the extra weight, which can put too much stress on smaller engines.
Why are American engines so big?
Decades ago, it decided on a policy of taxing motor fuel heavily. The consequence was that only a handful of rich people could afford cars with high fuel consumption. Those are big and heavy which means they need huge engines to provide reasonable performance.
