Small is the new big for fuel-efficient vehicles
When it comes to the fuel efficiency of your vehicle, smaller really can be better. Advancements in engine technology over the past 20 years mean drivers can achieve better fuel consumption without sacrificing performance. In fact, the relationship between engine size and fuel consumption is taking on a whole new dimension and that translates into increased savings and satisfaction for you - the consumer.
Do you want to know how it all works?
Basically, engine size is measured by the total volume displaced by the pistons in the cylinders as they move from their furthest point up to their furthest point down. As a result, engine size is also referred to as “displacement” and is com- monly measured in litres or cubic inches. In general, the larger the engine and the more cylinders it has (smaller engines usually have four cylinders, larger engines have six or eight — or more), the more fuel is consumed. Smaller engines tend to operate closer to their optimal efficiency levels under typical driving conditions, meaning more of the energy from the fuel is converted into work at the crankshaft, whereas in larger engines more of the available energy in the fuel consumed (under similar driving conditions) is lost to heat and friction.
So what does this all mean to you the driver and you the vehicle buyer? It all boils down to choice, lifestyle and whether or not fuel efficiency is important to you. If you are interested in saving fuel, saving money and reducing greenhouse gas emissions, the question to ask yourself is: do I really need that bigger engine if a smaller, more fuel-efficient one will do.
