The Lincoln Navigator currently uses a 3.5-liter EcoBoost twin-turbo V6 engine; there is no V8 option in the latest Navigator models.
To understand the question fully, it helps to look at how the Navigator’s powertrains have evolved over its generations, from early V8s to the modern EcoBoost V6.
Current engine option
What powers the modern Navigator is a single, high-output V6 designed to mix performance with towing capability and efficiency.
- 3.5-liter EcoBoost V6 twin-turbo engine — typically paired with a 10-speed automatic transmission, delivering roughly 440–450 horsepower and about 510 lb-ft of torque, depending on model year and trim.
Bottom line: in today’s lineup, the Navigator uses a V6 rather than a V8, and there is no contemporary V8 option.
Historical engine lineup
Earlier generations of the Navigator relied on traditional V8 powerplants, reflecting Ford/Lincoln’s standard practice before the broader shift to EcoBoost engines.
- 5.4-liter V8 — the long-running engine in the Navigator’s early and mid-generation years, providing strong power for towing and luxury SUV duty.
In summary, the Navigator’s history shows a move from V8 power toward the EcoBoost V6 in more recent years, aligning with industry trends toward forced-induction engines for efficiency and performance.
What this means for buyers
For prospective buyers, the key implications are fuel economy, maintenance considerations, and resale value. A modern Navigator with the 3.5L EcoBoost V6 emphasizes efficiency and torque delivery suitable for heavy loads and family hauling, while older, V8-powered Navigators may appeal to buyers who prioritize traditional V8 power and may come with different maintenance profiles and insurance considerations.
Summary
The Lincoln Navigator’s current generation is powered exclusively by a 3.5-liter EcoBoost V6, with no V8 option available in new models. Historically, earlier Navigators used 5.4-liter V8 engines, but the lineup shifted to the EcoBoost V6 in recent years. For buyers, this means focusing on turbocharged V6 performance and efficiency rather than a traditional V8 experience.
