Fuel economy numbers on window stickers rarely tell the full story. Canadian drivers deal with freezing mornings, long highway drives, winter tires, and heavy stop-and-go traffic. All those factors can turn decent official ratings into disappointing real-world fuel use. Large trucks, powerful SUVs, and performance cars often look appealing at dealerships. Yet many of them burn far more fuel once they face cold starts, snow, and long commutes. Before buying, it helps to know which vehicles struggle the most with real-world efficiency. Here are 21 vehicles with the worst real-world fuel economy (Canadian driving conditions).
Ford F-150 Raptor

The Ford F-150 Raptor delivers serious off-road ability and huge power. That power comes with a steep fuel bill. The twin-turbo V6 engine produces strong acceleration but drinks fuel quickly. Many Canadian drivers report real-world consumption of 16-18 L/100 km. Cold winters make things worse. Remote starts, heavy snow tires, and long idling increase fuel use further. The truck’s wide tires also create higher rolling resistance. Highway mileage rarely improves much either. The Raptor remains popular with truck fans. Yet drivers who commute daily often notice the fuel gauge dropping faster than expected after only a few days of typical Canadian driving.
Ram 1500 TRX

The Ram 1500 TRX is built around one thing. Raw power. Its supercharged V8 engine produces over 700 horsepower. That excitement comes with very heavy fuel use. Owners often report real numbers around 20 L/100 km or worse. Winter conditions amplify the problem. Thick engine oil and cold starts reduce efficiency further. The truck’s massive weight also plays a role. Aggressive tires and lifted suspension increase drag and rolling resistance. Even highway cruising struggles to stay efficient. The TRX attracts drivers who want performance above everything else. Still, anyone commuting long distances in Canada quickly notices the frequent fuel stops required.
Toyota Sequoia (Previous Generation V8)

Older Toyota Sequoia models with the V8 engine remain common in Canada. They are durable but rarely efficient. Real-world fuel economy often lands between 16 and 19 L/100 km. Cold climates worsen the situation. The large engine takes longer to warm up during winter mornings. Many owners also install winter tires and roof racks. Both reduce efficiency further. The Sequoia’s heavy frame and large body increase fuel consumption during city driving. Stoplights and short trips drain fuel quickly. Families like its space and reliability. However, daily driving costs can surprise buyers expecting better mileage from a well-known brand.
Jeep Wrangler Rubicon

The Jeep Wrangler Rubicon is built for trails, rocks, and mud. Efficiency was never its focus. Canadian drivers often see fuel economy around 14 to 16 L/100 km.
