No — Yukons come with multiple engine options, and the 6.2-liter V8 is not standard. It is typically available only on higher trims and select model years, while other Yukons use a 5.3-liter V8 or a 3.0-liter Duramax diesel.
Engine options in the Yukon lineup
GMC has offered three main powertrains for the Yukon in recent years. The 6.2-liter V8 is a high-performance option tied most closely to premium trims, while the 5.3-liter V8 covers the majority of models, and the 3.0-liter Duramax diesel delivers better highway efficiency. The exact availability depends on model year and trim level.
- 5.3L V8 (approximately 355 hp, 383 lb-ft of torque) — the baseline engine for many Yukon trims, paired with a 10-speed automatic transmission.
- 6.2L V8 (approximately 420 hp, 460 lb-ft of torque) — a higher-performance option commonly associated with Denali and Denali Ultimate trims; not standard on the base Yukon.
- 3.0L Duramax Turbo-Diesel I6 (approximately 277 hp, 460 lb-ft of torque) — a fuel-economy-focused alternative available on many Yukon configurations, also paired with a 10-speed automatic.
Availability of these engines varies by year and trim. Always verify the exact configuration on the dealership window sticker or official GM spec sheet for your specific Yukon model year and trim level.
What this means for shoppers
If you’re after maximum power, the 6.2L V8 in Denali/Denali Ultimate is typically the go-to choice. If you want a balance of performance and efficiency, the 5.3L V8 covers most everyday needs. For long highway trips or towing with improved fuel economy, the 3.0L Duramax diesel is worth considering. The key is to check the exact trim and year, as not all Yukon models offer every engine option.

Summary
The GMC Yukon does not universally use a 6.2-liter engine. The 6.2L V8 is available on higher trims (notably Denali/Denali Ultimate) in many model years, while the 5.3L V8 and the 3.0L Duramax diesel provide alternative options across other trims. To buy precisely what you want, check the specific engine availability for your Yukon’s year and trim and review the window sticker or official configuration sheet.
