When it comes to Going Green, driving an eco-friendly car is one of the best ways to minimize your carbon footprint and save some money. Most people flock towards cult favourites like the VolksWagen Beetle or BMW MINI (commonly called Mini Cooper), but what you gain in style you may lose at the pump. Here’s our breakdown of fuel-efficient cars you should consider.

(1) Hybrid Vehicles

How it works: Hybrid vehicles capture motion energy and convert it to heat energy which can be stored as electricity. The vehicle then operates on gasoline power or electricity, or both.

Why we love it: Short commutes can make the most of the electric energy source.  Longer distances will require the gas engine to take over, reducing the overall efficiency.

Popular Pick: Toyota Prius (from $27,800 CAD)
In the City: 51 mpg/ 4.6 L per 100km
On the Highway: 48 mpg/ 4.9 L per 100km

(2) Turbo Diesel (TDI)

How it works: The diesel engine can use standard diesel fuel or biodiesel, a synthetic fuel sourced from vegetable oil and methanol.  "Turbo" refers to the extra power, lower emissions, and better efficiency compared to standard diesel engines.

Why we love it: Europeans have been driving turbo diesel engines for years, so it's a proven technology.  The alternative fuel option is a forward-thinking move.

Popular Pick: VolksWagen Golf TDI (from $25,000 CAD)
In the City: 29 mpg/ 6.7 L per 100km
On the Highway: 40 mpg/ 4.7 L per 100km

(3) Natural Gas Vehicles

How it works: A natural gas vehicle runs on compressed natural gas, the same fuel that heats your home and cooks your food. You will need to find a fast-fill compressed natural gas station; try this locator for US stations.

Why we love it: A tankful costs around $6 and would take you about 200 miles (320 km).

Popular Pick: Honda Civic GX NGV (from $25,300 CAD)
In the City: 24 mpg/ 9.8 L per 100km
On the Highway: 36 mpg/ 6.5 L per 100km

(4) Electric Vehicles

How it works: 100% electric vehicles do not rely on fuel power at all.  Instead, the lithium-ion battery conveniently charges at home overnight (10 hours).

Why we love it:  Short commutes (eg. 40 miles/65 km total) will cost approximately $1.50 per day on your electric bill, about the same as a household appliance.

Popular Pick: Chevrolet Volt (from $41,000), available starting 2011
