Choosing an engine

Driving efficiently – choosing an engine

A number of factors will influence how efficient your motoring is, and it’s as much about the vehicle you choose as the way you drive it. Modern engines are increasingly becoming more and more refined, as manufacturers look to offset the impact their cars have on the environment.

Not only could choosing an efficient engine save you money through less trips to the pumps and road tax exemptions, you’ll also gain peace of mind that you’re helping reduce CO2 emissions. Read on for advice on choosing an efficient engine.

Petrol or diesel

Many motorists have their preference when it comes to fuel type, but making a change from the norm could improve your green motoring capabilities. Diesel engines are traditionally more fuel-efficient than petrol variations, as diesel possesses a greater amount of usable energy and you can therefore travel further on the same amount. However, diesel engines provide benefits over longer distances, so a refined modern petrol engine may make sense if you’re only making short trips.


Hybrid vehicles are growing in prominence, and with dwindling oil stocks they’re likely to dominate the motor industry in the not too distant future. With dual fuel sources, hybrid engines represent the most efficient choice available to modern motorists. Both petrol and diesel hybrid engines are manufactured, combining traditional combustion energy with battery power. Many hybrid vehicles can be powered solely on electric energy before switching to fuel when this runs out and it’s time to recharge. This means zero emissions over significant distances and no fuel burned, making one full tank stretch a lot further.

Energy saving technology

When looking to purchase a new or nearly-new vehicle, look for engines incorporating energy saving technologies. Almost all leading carmakers have developed their own engine systems that offer greater efficiency, from Volkswagen’s BlueMotion to BMW’s EfficientDynamics. Such features include start/stop technology which switches the engine off when stationary in traffic, complemented by low-rolling resistant tyres and energy recuperation systems.

When choosing your next fuel-efficient vehicle, look for a low CO2 emission figure and a high mpg figure and you can’t go far wrong. However, it pays to speak to the experts for a full explanation of why engine choice is so important to efficient driving.
