The Armada has only been sold with one engine thus far; the 317 horsepower V8 VK56DE. Buyers have a choice of rear wheel drive standard or four wheel drive optional.
This vehicle has only been sold with automatic transmission so far, a 5 speed.
The Armada has a towing capacity of 9100 pounds, which is better than most SUVs in its class but less than some of the supersized SUVs made by Ford and GM.
Consumer Reports has been very critical of the Armada due to reliability concerns. Those concerns are about the brakes, and they are justified for all models made before 2008. The problem has been fixed on newer models, and fixes are already being used on the early models to solve the design flaw.
These are not yet common on the used car market, but you can buy a used Nissan Armada from places like eBay.
