  1. 2020 Toyota Corolla Hatchback

The 2019 and 2020 Toyota Corolla Hatchback are 2 great car models with fuel-saving capacity along with other performance and safety perks.

The Corolla leads the charge in the Corolla lineup in terms of fuel-efficiency and features Continuous Variable Transmission (CVT) – which is vital for fuel management.

The SE model will prove a better choice as base models have better fuel economy than upper trim levels. If you would like something even more efficient, consider the hybrid version of the 2020 Toyota Corolla Hatchback.

The Hatchback comes with standard automatic high-beam headlights, automatic emergency braking, adaptive cruise control, and more.

  1. 2020 Kia Niro

Kia Niro offers 5 different trim levels – LX, LXS and Touring, Touring Special Edition, and EX Premium. It comes in hybrid, plug-in hybrid, and all-electric drivetrains.

The FE model stands out when it comes to good fuel economy compared to the other trims. It is the base model of the car and is more fuel-efficient.

The higher trims have more additional equipment that equals more weight, and the heavier a car is the more energy is needed to get it moving. Safety-wise, Kia Niro earns a Top Safety Pick+ spot award from the IIHS.

  1. 2020 Jaguar XE Diesel

This luxury midsize sedan has impressive fuel economy numbers. Its luxury status, however, has a bit of a question mark because of the low quality of its interior materials.

It also doesn’t have enough backseat room and overall, this Jaguar comes second-best when pitted against most competitors. But since the focus here is fuel efficiency, it’s a worthy candidate. Jaguar XE is available in 2 trim levels. 

  1. 2020 Honda Insight

Both the 2019 and 2020 models of Honda Insight offer impressive fuel economy numbers as well as safe and comfortable rides.

The Insight vehicles come with Honda Sensing safety and driver assistance systems which include the usual suspects – adaptive cruise control, automatic emergency braking, lane-keep assist – good enough to be awarded an IIHS Top Safety Pick+ stamp.

The 12-volt battery has an unusual position in the centre console and can be accessed by taking off the trim panel on the passenger side. This location allows for more trunk space and even weight distribution.

  1. 2020 Kia Optima Hybrid

On the list of hybrid vehicles, Kia Optima does not measure up well in terms of fuel efficiency but it does very well as a midsize car.

Thanks to its 2.0-litre four-cylinder engine, the car delivers up to 42 mpg (miles per gallon). The Optima Hybrid has great safety scores from the IIHS and includes a long list of standard equipment.

  1. 2020 Ford Fusion hybrid

The Ford Fusion Hybrid is a midsize sedan in a class of its own. It’s a great looking car, has many standard features, performs optimally on the road, has a very impressive 45.3 inches legroom (best for tall drivers), and of course, sips fuel.

It has ample interior space but the trunk space is limited due to the presence of its battery pack.

  1. 2020 Toyota Camry Hybrid

Toyota Camry is a widely-known car in the automotive industry, with top sale margins in Canada. Apart from being an all-round, likeable car, its fuel economy is simply amazing.

It has a city mileage rating of 21 kml (kilometres per litre) and a highway rating of 22 kml. The hybrid also has a very impressive safety rating with a Top Safety Pick+ award.

It features top-quality standard equipment that cost less compared to competitors. Of the 3 trim levels, LE, SE, and XLE, the LE trim offers better fuel-saving capacity owing to its smaller wheels compared to the larger ones on the other trim levels.

  1. 2020 Hyundai Kona

Here is another car that won’t squeeze you dry for fuel sake. It’s an SUV, one of the front-liners in its class. Its base engine is not-so-great but this can be replaced with an optional turbocharged engine which provides quick acceleration.

You get impressive driver assistance technologies even at the lower trims, and this SUV is relatively affordable compared to other small SUVs. If you don’t mind road noise then you should have no qualms considering the Kona.

  1. 2020 Honda Civic

The Honda Civic boasts an array of attractive features and a sophisticated interior that easily make it a favourite sedan car when placed side-by-side other compact sedans.

It is available in 5 trims. While the base LX trim has great fuel economy along with advanced safety features, the EX trim is a better choice.

This trim has a 1.5-litre turbocharged engine that packs more power than the standard 2.0, it is also more fuel-efficient cars you’d find. Every trim features the standard Honda Sensing Suite.

  1. 2020 Hyundai Ioniq Hybrid

You will get around 58 miles per gallon from this amazing hybrid car. In its class of hybrid cars, the Hyundai Ioniq hybrid is rated high when it comes to fuel conservation.

Apart from this, it has large cargo space and tons of helpful standard features. While the base Blue trim is the least expensive and most fuel-efficient, the midlevel SEL trim has more advanced safety features.

  1. 2020 Honda CR-V

The Honda CR-V is a likeable car that appeals to drivers of all ages, races, sizes, and more. Maybe it’s the Honda nameplate or the standard features and performance, or both.

It’s a great choice if you need a fuel-efficient car too. As for safety, the CR-V has an impressive range of safety apparatus which includes lane-keep assist, adaptive cruise control, and a road departure mitigation system.

It can determine when the driver crosses over a lane without signaling and provides assistance back to the lane, or braking to keep from skidding off the road.

  1. 2020 Audi A4

If luxury cars pique your interest, Audi A4 is a great choice any time. Its tech integrations are simply very impressive and performance is at its peak.

Equally important is its ability to go easy on fuel consumption. Its base trim can offer up to 30 mpg. The A4 luxury sedan is available in 3 trims: Premium, Premium Plus, and Prestige. 

  1. 2020 Mazda C-X3

When a car is described as a modern classic you know there is something very special about it. apart from the oxymoronic rhetoric, the idea behind the term jumps at you – you should think of the CX-3 as a classic car, even in these present times. And it delivers well.

On top of all its accolades which includes a sleek design, powerful engine, engaging driver experience, to mention a few, it’s one of the most fuel-efficient cars worth buying.

  1. 2020 Toyota Yaris

Toyota Yaris is one of the least priced cars in Toyota’s lineup. It is small but not lacking in features. It’s incredibly fuel-efficient, has beautiful interior design, and lots of impressive standard features.

If you are a tall driver, you may find it difficult driving this car comfortably. This is owing to a very limited interior space. Cargo space isn’t the best either.

  1. 2020 Toyota Corolla

Unarguably at the forefront of Toyota best-selling, widely appreciated, and popular model. Toyota’s Corolla stands out in many ways, and one of the reasons is being one of the most fuel-efficient cars around.

It has very strong numbers here. With this car coupled with purposeful driving habits, you could get much higher mpg. One drawback is the absence of Android integration – a big letdown for 2020.

  1. 2020 Nissan Versa

Nissan Versa is certainly not one of the fastest cars you will find in the market but it earns its place as one of the most fuel-efficient cars.

Its 1.6-litre four-cylinder engine has a horsepower of 122 but its fuel economy rating reaches up to 35 mpg. You can achieve this feat by getting the optional Continuous Variable Transmission package.

Or you could opt for the SV and SR models where CVT is a standard feature.

  1. 2020 Hyundai Elantra Eco

With a combined rating of 36 mpg, the Hyundai Elantra makes it to our list of most fuel-efficient cars.

We are particular about the Eco trim because it houses a 1.4-litre turbocharged engine plus a 7-speed dual-clutch transmission. And these two fused allows the Elantra sip fuel (among other things).

In all, there are 4 trim levels of the Elantra. You might want to check out the other 3.

  1. 2020 Lexus ES Hybrid

This Lexus takes fuel efficiency to another level, hitting a 44 mpg rating. The 2019 edition was a new design with an improved hybrid drive system. It includes a 2.5-litre gasoline engine and a newly introduced electric motor.

This combined effort produces 215 horsepower. These, along with many other features are retained in the 2020 model.

If you choose the Lexus ES Hybrid, you get many driver and safety systems standard. But you’d have to deal with its clunky infotainment system.

  1.  Chevrolet Volt

Here’s a car Chevrolet is truly proud of (not to say they are not proud of the many Chevy models in their lineup). They call it an extended-range electric vehicle and the performance of the Volt speaks for itself.

As a hybrid (without external charging) you can expect a combined 42 mpg. But when connected to an external charger, you get 106 miles per gallon equivalent. Incredible! Chevy’s Volt also has amazing safety ratings.

  1. 2020 Toyota RAV4

Closing our list of 25 most fuel-efficient cars is the RAV4. A reliable nameplate with a potpourri of impressive features for the 2020 model.

It’s got all-wheel drive, satellite radio, Android Auto, WI-Fi hotspot, and more, propelling this compact crossover SUV is a 2.5 -litre four-cylinder engine. It’s ideal for anyone looking for a car that sips fuel and is reliable.

  1. 2020 Mitsubishi Mirage

The 2020 Mitsubishi Mirage is one of those cars that has very few highpoints worth talking about.

For the Mirage, it is its impressive fuel economy and the fact that it’s one of the least expensive cars you will find.

Buyers will find that a full tank could last a lifetime before running out but that’s where the good news ends. The interior design isn’t up to scratch, the engine doesn’t deliver enough horsepower and it’s quite uncomfortable inside.

But if fuel-efficiency is just what you need, the Mirage is a great option. But keep in mind that there are similarly priced fuel-efficient vehicles you can opt for. 

  1. 2020 Honda Fit

One of such similarly priced or low budget vehicles is Honda Fit. At CA $23,200, you get a very impressive fuel-efficient car that also saves cost at the dealership.

Honda Fit also typifies the saying “big things come in small packages”- which specifically relates to its small frame but highly spacious interior.

The interior is also customizable as the second-row seat can be moved in several ways to accommodate passengers or cargo.

The front seat can also be folded to suit your current needs – whether it’s to make room for long items or create a makeshift bed…just about anything. 

  1. 2020 Toyota Avalon

The Toyota Avalon has great fuel-sipping scores and also offers superior handling and performance.

It comes with Toyota Racing Development (TRD) that “applies its track-tuning expertise to Avalon for greater handling, thrilling performance and bold styling.”

In addition to its fuel-efficiency and overall performance, it passes the IIHS crash prevention tests with flying colors. And there’s the Toyota Safety Sense that is packed with ample driver assistance technologies you can count on. 

  1. 2020 Kia Rio

The 2020 Kia Rio is a front-wheel-drive subcompact car that comes in sedan and hatchback body styles.

The 2020 Kia Rio comes with an upgrade to its transmission with a CVT automatic compared to the 2019 model’s traditional automatic transmission.

It is one of the most fuel-efficient cars and this doesn’t come at the expense of performance like the Mitsubishi Mirage. There’s only one trim level and it has a long list of standard features.

  1. 2020 Toyota Prius Prime

The 2020 Toyota Prius is an overall comfortable and high-performing car. It has good interior space and cargo area.

Its fuel-efficiency rating is impressive and better appreciated in the base L Eco trim level. It’s a great choice if you need a car that’s has everything going for it as well as a great fuel-sipping score.
