What You'll Learn

The Jeep Wrangler
The Wrangler's fuel efficiency is largely attributed to its 3.0-liter EcoDiesel V6 engine, which was first introduced in the 2020 Unlimited model. This engine is known for its high torque and efficient fuel consumption. The EcoDiesel engine is an optional upgrade for the Wrangler, enhancing its fuel economy and reliability.
The fuel efficiency of the Jeep Wrangler varies depending on the model year and configuration. For example, the 2024 Jeep Wrangler offers 17 city mpg and 23 highway mpg for the two-door version, while the four-door versions provide slightly lower mileage at 16 city mpg and 22 highway mpg. However, the Sahara trim stands out with 20 city mpg and 20 highway mpg.
The Wrangler's fuel efficiency can be further improved by opting for the Wrangler 4xe plug-in hybrid (PHEV) model, which boasts even higher mpg figures. Additionally, the choice between manual and automatic transmissions influences fuel consumption, with manual transmissions typically resulting in higher fuel costs.
While the EcoDiesel engine comes at a higher price, it delivers significant advantages in terms of torque, smoothness, refinement, noise levels, and overall performance. The Wrangler's fuel efficiency, combined with its off-road capabilities, cargo space, and classic Wrangler look, make it a highly coveted SUV in its segment.

The Nissan Qashqai
The 2025 Nissan Qashqai stands out for its impressive fuel efficiency. According to Parkers, a renowned automotive resource, the 1.3-litre mild hybrid engine variants of this model offer exceptional fuel economy. Official WLTP testing reveals that these engines achieve approximately 44 mpg, with carbon dioxide emissions ranging from 142 to 145g/km. Notably, the choice of gearbox and driving conditions can significantly influence actual fuel efficiency. For instance, an automatic 158hp Nissan Qashqai Tekna+ test drive resulted in a remarkable 47.1 mpg, even without specific efforts to optimise fuel economy.
The previous generation of the Nissan Qashqai, including the 2016-2021 models, also demonstrated impressive fuel efficiency. The 1.5-litre diesel engine, delivering smooth power and ample pull from low revs, is particularly noteworthy. This engine option not only provides a comfortable and well-equipped driving experience but also stands out for its fuel efficiency, making it a cost-effective choice for families.
While the 2022 model of the Nissan Qashqai has shifted towards hybrid technology, the diesel variants remain competitive in terms of fuel economy. The 1.3-litre DIG-T engine, with 140 or 160 horsepower, is expected to deliver 38-40 mpg. Notably, the manual version is more fuel-efficient than its automatic counterpart. Diesel models are also highlighted for their low maintenance costs, contributing to their overall appeal.
It is worth noting that other diesel SUVs, such as the Jeep Wrangler Unlimited, the GMC Terrain, and the Volkswagen T-Roc, also offer notable fuel efficiency within the SUV segment. However, the Nissan Qashqai, particularly the 2025 model, stands out for its combination of fuel economy, performance, and features, making it a well-rounded choice for those seeking a fuel-efficient SUV.
