most fuel efficient cars

Ready to swap that gas-guzzling clunker for a planet-hugging ride? Well, you’re in luck, because we’ve lined up the most fuel-efficient cars in Canada. These lean, green, money-saving machines are here to soothe your pain at the pumps. We explore fuel economy across the most common car classes, from sedans to trucks and fan-favourite SUVs. Hold on to your toque as we zip through the 10 most fuel-efficient cars in Canada and how to cruise into big fuel savings. 

What does fuel efficient mean? 

Fuel efficiency is all about getting the most out of every drop of fuel. A fuel-efficient car lets you drive further without constantly refilling the tank, which saves money on gas while helping the environment. It’s like having a superhero car that goes the extra mile, keeping both your wallet and Mother Earth happy.

What to know about fuel consumption ratings

Fuel consumption ratings are like nutritional labels for vehicles. They’re a reliable way to compare fuel efficiency across makes and models, but things can get confusing if you don’t know what to look for. In Canada, fuel consumption ratings are expressed as Litres per 100 km driven (L/100 km). In the US, consumption ratings are expressed as Miles Per Gallon (mpg).

To keep it simple, here’s the golden rule of fuel consumption ratings: the lower the litres per 100 kilometres (L/100 km) rating, the more fuel-efficient the vehicle. And the higher the miles per gallon (mpg) rating, the further it can stretch each gallon of gas, which also means better fuel efficiency. Keep this in mind, and you’ll be well on your way to finding the perfect fuel-efficient car for your next adventure (yay!) or trip to the office (boo!).

⬇️ Low Litres/100 km = Good!

⬆️ High Miles/Gallon (mpg) = Good!

These ratings allow you to accurately compare different fuel-efficient cars to find the money-saving champion that perfectly fits your lifestyle. A vehicle with the best fuel consumption ratings and lowest estimated annual fuel cost is like investing in a long-term savings account that keeps both your gas expenses and environmental impact low for years to come.

Is a new fuel-efficient car worth the purchase price?

When it comes to buying a new car, there are a ton of numbers to crunch. And if you’re looking for the most fuel-efficient car to save money on gas, all that number crunching can be overwhelming at best – confusing at worst.   

To calculate how much money you can save with a new fuel-efficient car, you’ll need to compare its fuel consumption with that of your current vehicle. Here’s a step-by-step guide to help you with this comparison:

1. Determine the fuel consumption rating of both vehicles 

Find the fuel consumption ratings for your current car and the new fuel-efficient car you’re considering. This is usually expressed in miles per gallon (mpg) or litres per 100 kilometres (L/100 km).


⬆️ High miles per gallon (mpg) = Good!

⬇️ Low litres per 100k = Good!

2. Calculate your annual fuel consumption

Estimate the number of kilometres you drive in a year. Divide that by the fuel consumption rating of each car to find out how many litres of gas you’ll consume annually. If the rating is in miles per gallon, convert it to litres per 100 km like this:

  1. 1 US Gallon = 3.78541 L
  2. 1 Mile = 1.60934 km

Formula: Liters per 100 km = (100 x 3.78541) / (MPG x 1.60934)

For example, let’s convert a fuel efficiency of 35 miles per gallon (MPG) to litres per 100 kilometres (L/100 km) using the formula:

Liters per 100 km = (100 x 3.78541) / (MPG x 1.60934)

Substitute the MPG value of 35 into the formula:

Liters per 100 km = (100 x 3.78541) / (35 x 1.60934)

Perform the calculations:

Litres per 100 km = (378.541) / (56.327)

Litres per 100 km ≈ 6.72 L/100 km

Therefore, a vehicle with a fuel efficiency of 35 mpg consumes approximately 6.72 litres of gas per 100 kilometres driven, expressed as 6.72 L/100 km.

Now let’s calculate how much gas you’ll need

For example, if you drive 24,140 km per year and your current car has a fuel consumption rating of 20 mpg, or 11.76 L/100 km, you’ll consume 2,839 litres of fuel annually:

  1. 24,140 km x (11.76 L/100 km)
  2. 24,140 km x 0.1176 = 2,839 litres

If the new car has a rating of 30 mpg, or 7.84 L/100 km, you’ll consume 1,892 litres of fuel annually:

  1. 24,140 km x (7.84 L/100 km)
  2. 24,140 km x 0.0784 = 1,892 litres

3. Calculate your annual fuel cost

Find the current price of gas per litre in your area. Multiply your annual fuel consumption by the gas price to get the annual cost of gas for each vehicle. For example, if the fuel price is $1.55 per litre, your current car’s annual fuel cost is $4,400.45:

2,839 litres x $1.55 = $4,400.45

The new car’s annual fuel cost is $2,932.60:

1,892 litres x $1.55 = $2,932.60

4. Calculate the annual savings

Subtract the annual fuel cost of the new car from that of your current car. In this example, you would save $1,467.85 per year:

$4,400.45 – $2,932.60 = $1,467.85

5. Compare the savings to the selling price

Now that you know your annual savings, you can estimate how long it would take to recoup the extra cost of the new fuel-efficient car. Divide the price difference between the new and current cars by the annual savings.

For example, if the new car costs $5,000 more than your current car, it would take you about 3.4 years to break even on your investment:

$5,000 / $1,467.85 = 3.406

A word about hybrids

While hybrids are consistently the most fuel-efficient cars (that are not fully electric), they come with additional costs to be aware of. Hybrid vehicles are usually more expensive to buy than their gas-guzzling counterparts. That means you’ll probably spend more on the sticker price, which could take several years to recoup through fuel savings unless you opt for a lower trim level or base model. 

The maintenance and repair costs can also be higher thanks to their unique powertrain components. This includes the cost of replacing the hybrid battery, which can be thousands of dollars. Some manufacturers offer robust extended warranty coverage for hybrid batteries, but it’s important to factor in these potential costs when considering a hybrid vehicle. 

While hybrids are generally more fuel-efficient cars, it’s essential to weigh the potential cost savings against the higher initial price and maintenance costs to determine if a hybrid is the right choice for your budget.

How to choose a fuel-efficient car

If you’re reading this, you’re probably on the market for a vehicle that will save you money at the pump, contributes to a cleaner environment, or both. Here are some key factors to consider when choosing a fuel-efficient car that meets your needs:

Determine your priorities 

Consider the main factors that are important to you, such as size, seating capacity, cargo space, performance, and driving conditions. This will help you narrow down the list of potential vehicles.

Research fuel consumption ratings 

Look for the fuel consumption ratings of vehicles that match your priorities. As we discussed earlier, the lower the L/100 km rating the better the fuel efficiency. Also, the higher the mpg rating, the less fuel the vehicle consumes.

Explore different powertrains

There are various powertrain options available, including gasoline, diesel, hybrid, plug-in hybrid, and electric vehicles. Each has its own benefits and drawbacks, so choose the one that aligns with your preferences and driving habits.

Consider the total cost of ownership

While fuel efficiency is important if you want to save money on gas, there are still all the other ownership costs to consider. Shop around to compare car insurance premiums, budget for maintenance and depreciation, and consider the financing costs if you need a car loan. A fuel-efficient car that also has low ownership costs can save you even more money in the long run.

Take a test drive

Once you’ve narrowed down your options, take each vehicle for a test drive to assess its performance, comfort, and overall driving experience. This will help you determine if the vehicle meets your expectations in terms of fuel efficiency and practicality.

Check for incentives and rebates

The Government of Canada and some manufacturers offer incentives and rebates for eco-friendly or fuel-efficient cars. Look for any available incentives in your region, as they can significantly lower the purchase price and make your fuel-efficient car choice even more economical. 

Driving tips to save money on gas

We’re all tired of getting gut-punched at the pump. No matter what kind of car you have, small adjustments to the way you drive can reduce your fuel consumption and keep more cash in your pocket. Here are the top driving tips to save money on gas (#11 is my favourite!).

Accelerate smoothly

Smooth moves win your wallet. Channel your inner Zen and ease into the gas pedal. Smooth acceleration saves fuel and keeps you looking cool.

Steady Eddie 

Embrace your inner tortoise and maintain a consistent speed. Resist the urge to speed or weave in and out of traffic. Trust us, your wallet will thank you.

Shut it down

Idle engines are a non-starter. If you’re parked for more than a minute, give your engine a break and turn it off. Save fuel and the planet, one engine-off moment at a time.

The only good inflation

Inflate good vibes and your savings when you keep your tires plump and happy. Properly inflated tires can save you some serious cash at the pump.

Plan ahead

Become an errand ninja! Plan your trips like a stealthy shopping warrior so you’re not making multiple trips, or backtracking around town. Combine errands into one trip and plan your route to avoid adding unnecessary kilometres. This will help you save on gas and get back to binge-watching your favourite show.

Lean and green

Shed the excess baggage from your car by ditching the junk in your trunk (literally). A lighter car means better fuel efficiency and more gas money for the fun stuff. Time to say goodbye to the box of donations you’ve been driving around with for 3 months. 

Slow and steady

Speed demons beware – take the pedal off the metal! Cruising at reasonable speeds can save fuel and keep you out of the clutches of those pesky speed traps. Not only will driving fast kill your fuel efficiency, but speeding tickets take a chunk out of your wallet and can increase your car insurance premiums when it’s time to renew. 

Some like it hot

A/C or not A/C, that is the question. Only it’s not a question, it’s a fact that air conditioning can guzzle gas like nobody’s business. Use it wisely or roll down the windows and enjoy the breeze, your budget and your dog will love you forever. 

Treat em’ right

Pamper your ride by taking good care of it. Treat your car to regular maintenance like oil changes, spark plug checks, tire rotations and seasonal change-overs. A well-cared-for car sips fuel like a fine wine – instead of guzzling it like it’s Frosh Week at college. 

Fuel ABCs

Fuel grade matters, so stick to the recommended fuel grade for your vehicle. You’ll save money on gas if you avoid the temptation of that fancy-sounding high-octane fuel. Your car probably doesn’t need it, and neither does your bank account.

Pay with plastic

A credit card that offers the highest rewards, points, or cashback on fuel purchases is the easiest way to maximize savings at the pump. With the best credit card for gas, you’ll be able to offset a portion of your gas expenses over time. This strategy not only helps you save money but also allows you to take advantage of additional perks and benefits that come with the card, making every fill-up more rewarding and budget-friendly.
