Fuel-hungry models: Toyota Land Cruiser, Mercedes Geländewagen, and Range Rover
The Toyota Land Cruiser, Mercedes Geländewagen, and Range Rover are notorious for their high fuel consumption. These four-wheel-drive vehicles are designed to handle any road conditions, but their fuel efficiency leaves much to be desired.
Let's start with the Toyota Land Cruiser. The petrol version of this SUV is equipped with a powerful 5.7-litre V8 engine that guzzles more than 20 litres per 100 km on average. That's a significant fuel cost, especially for those who drive long distances or commute frequently. On the positive side, Japanese engines like the one in the Land Cruiser are known for their flexibility when it comes to fuel type.
Moving on to the Mercedes Geländewagen, another four-wheel-drive vehicle with a thirst for fuel. In a combined cycle, this car consumes 22 litres per 100 km, similar to V8 and V12 modifications. It's important to note that this high fuel consumption refers specifically to the customized AMG versions of the Geländewagen. Standard diesel engine versions of the Geländewagen are known to exist and are likely to be more fuel-efficient.
The Range Rover, a British icon, is also known for its high fuel consumption. Whether it's the elegant long-bodied version or the sporty variant, the Range Rover consumes 12.8 litres of 95 octane unleaded petrol per 100 km. However, this is just the starting point, as fuel consumption can quickly climb to 18 litres per 100 km in urban driving conditions, according to specifications.
It's worth noting that while these vehicles have high fuel consumption, other factors come into play. For example, the Hummer H2, with its 6.0 and 6.2-litre V8 engine, consumes 28 litres per 100 km. However, by avoiding aggressive acceleration, drivers can achieve a more modest 17 litres per 100 km, which is comparable to other fuel-hungry models. Additionally, while the Mercedes-Benz brand recommends premium fuel for optimal performance, some owners have found that their vehicles run just fine on regular gas, which can help offset the high fuel costs associated with these cars.

Four-wheel drives: Hummer H2, Chevrolet Tahoe, and Cadillac Escalade
Four-wheel drives are known to be fuel-hungry vehicles. Here is a look at some of the four-wheel drives with high fuel consumption:
Hummer H2
The Hummer H2 is a large vehicle fitted with a 6.0 or 6.2-litre V8 engine. It consumes 28 litres of fuel per 100 km, which is relatively efficient considering its size. A tank of fuel will last for 400 km. However, if you accelerate less, you can achieve a more efficient 17 litres per 100 km.
Chevrolet Tahoe
The Chevrolet Tahoe is a fuel-thirsty vehicle, especially if you delete the dod/afm. It is fitted with a 5.3 or 6.2-litre engine, with the 6.2-litre option requiring premium fuel. On average, the Chevrolet Tahoe gets around 15-16 miles per gallon (mpg) in the city. On the highway, it can achieve 19 mpg.
Cadillac Escalade
The Cadillac Escalade is a luxurious four-wheel drive that comes with two body styles, three engine options, and five trims. The engine options include a 5.3 or 6.2-litre engine, with the 6.2-litre version delivering better fuel efficiency in some cases. The Cadillac Escalade fitted with the 6.2-litre engine can achieve 21 litres per 100 km.
Lincoln Navigator Ultimate and Ford Expedition EL
The Lincoln Navigator Ultimate and Ford Expedition EL are two Hummer-related models with large bodies and 5.4-litre V8 engines. They are more fuel-efficient than the Hummer H2, consuming 21 litres per 100 km.

Classic engines: Bentley Brooklands, Azure, and Arnage RL
While the Bentley Meteor is recognised as the "most fuel-hungry" vehicle globally, other Bentley models are also known for their high fuel consumption. The Bentley Brooklands, Azure, and Arnage RL are fitted with a classic 6.75-litre V8 engine. Initially, the Arnage RL engine version did not fit the standard consumption rate, and over time, the Brooklands, Azure, and Arnage did not become more fuel-efficient. These cars have an average fuel consumption of 27 litres per 100 km.
The Bentley Brooklands is a large, luxurious coupe, part of the Bentley State Limousine project, and was produced from 2008 to 2011. The Azure, a four-seater convertible, was introduced in 2006 as the second generation of the Azure line, replacing the previous model's turbocharged engine with a twin-turbocharged engine. The Arnage RL is a high-performance luxury car, first introduced in 1998, and is the first Arnage model to feature a turbocharged engine.
The 6.75-litre V8 engine is a significant feature of these classic Bentleys, offering powerful performance but also contributing to their high fuel consumption. While these cars are known for their elegance and performance, their fuel efficiency has not been a primary focus. The large engine displacement and the resulting high fuel consumption are characteristic of these classic Bentley models.
In comparison to other fuel-hungry cars, the Hummer H2, with its 6.0 and 6.2-litre V8 engine, consumes 28 litres per 100 km. The Toyota Land Cruiser, with a 5.7-litre V8 engine, consumes over 20 litres per 100 km on average. The Mercedes Geländewagen, a four-wheel-drive car, consumes 22 litres per 100 km in the combined cycle. These cars, including the Bentley Brooklands, Azure, and Arnage RL, are notable for their powerful engines and luxurious designs, but their fuel efficiency falls behind more modern or fuel-efficient vehicles.

Fuel-saving techniques: turn off air-con, avoid short trips, and steady acceleration
Fuel-saving, or fuel-efficient, driving techniques can save you money, improve road safety, and reduce wear on your vehicle. Here are some ways to improve fuel efficiency:
Turn off air-con
Air conditioning can increase fuel consumption by more than 20% in city driving. A more fuel-efficient option is to open a window, but only at low speeds. At high speeds, open windows increase aerodynamic drag, making the engine work harder and consume more fuel. If you must use air conditioning, avoid running it continuously. Turn it off once the interior is cool, or set the controls to a comfortable level that allows the system to cycle.
Avoid short trips
Your engine needs time to warm up to its most fuel-efficient temperature. Driving short distances means your engine will likely still be cold when you arrive at your destination. Combining several short trips into one longer trip allows your engine to reach peak operating temperature, reducing fuel consumption.
Steady acceleration
Aggressive driving, including frequent rapid acceleration, can increase fuel consumption by approximately 40%. Driving at a steady speed is more fuel-efficient, so accelerate smoothly when passing or merging with faster traffic, and avoid hard braking. Driving at the posted speed limit can also help, as vehicles tend to be most fuel-efficient when travelling between 50 and 80 km per hour. Above this speed zone, vehicles use more fuel the faster they go.
Other tips
- Regular maintenance, such as oil and filter changes, can keep your vehicle operating at its most fuel-efficient level. A clogged air filter can increase fuel consumption by up to 10%.
- Driving with a gentle touch can improve fuel efficiency. Imagine there's an open cup of coffee on your dashboard that you don't want to spill.
- Plan your trips to avoid traffic jams, steep hills, and road construction.
- Avoid roads that cut through major cities, as these tend to be dotted with stoplights and intersections.
- Keep your tires properly inflated. Check the tire pressure at least once a month when the tires are cold.
