The Nissan Frontier is a mid-size pickup truck that has been in production since 1997. The current generation of the Frontier was introduced in 2004, and it is due for a redesign in 2025. The 2025 Nissan Frontier is expected to receive a number of updates, including a new engine, a new transmission, and a new interior. One of the most important updates to the 2025 Nissan Frontier is the new engine. The current Frontier is powered by a 4.0-liter V6 engine that produces 261 horsepower and 281 lb-ft of torque. The new engine is expected to be a 3.8-liter V6 engine that produces more horsepower and torque. This will give the Frontier more power for towing and hauling.
