GMC Yukon

What is the GMC Yukon?

The GMC Yukon is a full-size SUV that brings the brand’s truck-focused character to a passenger vehicle. It has been part of GMC’s range since the early 1990s. Denali, first introduced on the Yukon for the 1999 model year, gives the SUV a more premium look and cabin.

The Yukon is also recorded in European Union registration figures. In 2025, the EU recorded 19 petrol Yukons: the listed model had a 6.2 L engine rated at 313 kW (426 PS).

Yukon generations

The first generation, GMT430, ran from 1992 to 1999. GMT800 was the second generation, covering 2000–2006; it brought more rounded exterior styling and a redesigned cabin. The third generation, GMT900, followed for 2007–2014 with a more angular appearance. The fourth generation, K2XX, ran from 2015 to 2020, and the fifth, T1XX, began in 2021 and continues today.

The Yukon has remained a full-size SUV through these generations. Denali has been part of its story since the late 1990s, adding distinctive styling and a more premium cabin.

Engines, power and fuel consumption

US EPA listings cover Yukon engines from 3.0 L to 6.5 L and include diesel, petrol, E85 flex-fuel and hybrid versions. Canadian NRCan listings cover the same engine-size range and include diesel, petrol and E85 flex-fuel versions. The EU’s 2025 listing is for a petrol Yukon with 313 kW (426 PS).

The lowest stated US consumption is 10.2 L/100 km, and the best combined EPA rating is 23 MPG. Canada’s lowest stated figure is 10.1 L/100 km under the NRCan 5-cycle test. European ratings use WLTP or, for some older vehicles, NEDC; these procedures differ from the EPA and Canadian 5-cycle tests, so ratings across markets are not directly equivalent.
