Fuel economy
The GMC Yukon offers a range of powertrain options, including a diesel engine that is ideal for heavy-duty towing. The diesel engine option is available in the GMC Yukon's full-size SUV lineup.
The 3.0L I6 LM2 turbodiesel Duramax engine offers impressive fuel economy gains over the gas-powered alternatives. According to the official EPA estimates, the 2021 GMC Yukon models equipped with this engine and 2WD post fuel returns of 21 mpg in the city, 27 mpg on the highway, and 23 mpg combined. This is an improvement over the smaller 5.3-liter V-8 engine, which has an EPA rating of 15 mpg in the city and 20 mpg on the highway.
The GMC Yukon Denali 4x4, a heavy, luxury-laden SUV, offers slightly lower city efficiency, earning 14 mpg in the city and 19 mpg on the highway. The diesel engine in this model, however, has been reported to deliver even better fuel economy than the EPA estimates. One test drive resulted in a fuel economy rating of 26.9 mpg, nearly 5 mpg better than expected. Another test drive of the same model resulted in a combined fuel economy of 27.9 mpg over 206.1 miles.
The GMC Yukon's 24-gallon fuel tank, combined with its impressive fuel efficiency, allows for extended journeys without frequent fuel stops, making it an excellent choice for long-distance travelers.

Cost considerations
When considering the costs of the GMC Yukon, it is important to weigh the initial price of the vehicle against the long-term fuel costs. The diesel engine option for the GMC Yukon has a higher upfront cost compared to its gas-powered counterparts. However, the diesel engine offers superior fuel economy, which can lead to significant long-term savings.
The diesel engine's fuel efficiency is impressive, achieving 21-23 mpg in the city and 27-29 mpg on the highway, according to various sources. This translates to an estimated annual fuel cost of $1,550 for the 2021 GMC Yukon diesel model, according to the EPA. In contrast, the gas-powered models with a 5.3L V8 engine have an estimated annual fuel cost of $1,750. The diesel engine's extended range of approximately 600 miles on a full tank means fewer refuelling stops, resulting in both time and money savings.
The choice between diesel and gas engines depends on driving habits and preferences. If you frequently drive long distances, the diesel engine's superior fuel economy and range will result in considerable cost savings over time. On the other hand, if your driving is mostly limited to shorter distances or city driving, the gas engine's extra horsepower and quicker acceleration may be more advantageous, despite the slightly higher fuel costs.
It is worth noting that the diesel engine's cost considerations also include environmental impact differences. The diesel engine's higher torque and better fuel economy come at the cost of a higher initial price. However, the quieter and more refined rumble of the gas engine, especially during idle or hard acceleration, may be a factor for some buyers.
Ultimately, the cost considerations for the GMC Yukon's diesel engine option depend on a combination of upfront costs, long-term fuel savings, driving habits, and environmental concerns.

Environmental impact
The GMC Yukon offers a 3.0-liter turbo-diesel engine option, which delivers excellent fuel economy. The diesel engine option provides strong towing capacity and is ideal for long-distance driving due to its fuel efficiency.
The environmental impact of the GMC Yukon diesel engine is a key consideration when choosing between the diesel and gas engine options. While diesel engines offer better fuel economy and range, gas engines are generally considered more environmentally friendly as they release fewer nitrogen oxides and particulates.
However, it is important to note that gas engines still emit carbon dioxide and other pollutants that contribute to global warming. In the short term, gas engines may be less detrimental to air quality, but their overall environmental impact remains significant.
Electric vehicles, on the other hand, offer a greener alternative with zero tailpipe emissions and a smaller environmental footprint, especially when powered by renewable energy. They typically have lower lifetime emissions compared to diesel and gas engines.
The environmental impact of the GMC Yukon diesel engine is, therefore, a complex issue that requires considering fuel economy, emissions, and alternative fuel options. While the diesel engine's fuel efficiency may reduce fuel consumption, the higher emissions of nitrogen oxides and particulates could have a more detrimental environmental impact in the long term.
Ultimately, the environmental impact of the GMC Yukon diesel engine will depend on various factors, including driving habits, fuel type, and the availability of alternative fuel options.
