NASHVILLE, Tennessee--(BUSINESS WIRE)--The 2025 Nissan Armada’s1 engine, like its design, is built to meet a range of needs: from tackling harsh off-road terrain on the weekend to quietly transporting families during the week. Plus, it can tow up to 8,500 lbs.2
The 2025 Armada is faster, more powerful and more efficient than its predecessor. This remarkable feat is achieved with a new powertrain, including a twin-turbo V6 that delivers an impressive 516 lb-ft of torque3 – more than any other production engine Nissan has ever made.
To accomplish this, engineers leaned on their decades of experience developing cutting-edge powertrains.
“Within Nissan’s development team, there is a treasure trove of knowledge,” said Sho Takahashi, senior manager in Nissan’s Engine Engineering Department. “We didn’t just build a powerful engine - we created a solution that meets the needs of today’s drivers, whether they’re adventuring off-road or navigating everyday commutes.”
For example, to help reduce engine noise even while increasing output, the team equipped the turbochargers with a small groove at the entrance to the compressor. Based on technology first used in the Japanese-market Skyline, the feature decreases turbulence and stalling in the compressor entry, resulting in a 4dB reduction in turbo noise — a noticeable difference for the average human ear.
“This proprietary technology is the culmination of years of Nissan innovation,” said Takahashi, who has been with Nissan since 2004. “It highlights how we’re continuously pushing boundaries to deliver quieter, more efficient and more powerful vehicles to our customers.”
Another innovation can also be found in the twin-turbo system: The turbine wheels are crafted from Mar-M, a special nickel-based superalloy material that can withstand extreme heat and is resistant to corrosion and oxidation, helping to ensure Armada’s engine is built to last.
“This material is currently used in jet engines and gas turbines because of its exceptional durability under extreme heat,” said Takahashi. “By applying this technology to Armada, we’re helping to ensure long-lasting performance and reliability in any condition.”
The 2025 Armada is also the only SUV in its class with a “scavenger” oil pump, a feature designed to enhance lubrication in driving conditions with high g-forces. The system was first used in GT-R to maintain high power in tight corners. It was implemented in the new engine so that Armada’s sibling – the Nissan Patrol – can climb steep desert dunes in the Middle East.
In North America, engineers spent countless hours in 13 states refining the engine for consistent performance, no matter the environment – from a Minnesota winter to a Death Valley summer.
“That’s why we confirmed the new engine in all these locations and temperatures multiple times during development,” explained Dave Kiesel, manager in the Powertrain Performance Group at Nissan’s Arizona Testing Center. “There are many design and calibration items specifically used to ensure performance for the U.S. For example, we put the vehicle through a variety of towing tests to validate high performance even when towing a heavy load.”
And while the V6 has an impressive 425 horsepower3, the new 9-speed automatic transmission helps deliver it smoothly to the driver. To do this, engineers adjusted the gear ratios to provide a quick yet refined response, especially from a standstill.
“With increased torque and a wider gear ratio, drivers will feel confident in their vehicle’s ability to accelerate smoothly and powerfully, no matter if they’re merging onto the highway or navigating tough terrain,” Kiesel said.
In a similar vein, engineers carefully adjusted the engine mounts and balanced key components like the crankshaft so that there is no increased vibration despite the increase in power.
Drivers may also notice enhanced throttle response thanks in large part to new electric intake valve timing, making for a sporty feel that belies Armada’s size.
Engineers made many precise adjustments to wring out more power while using less fuel. One of the most significant choices was to use increased fuel pressure (35 mega pascals compared to 15 mega pascals on the outgoing V8) combined with longer piston strokes (100.2 mm compared to 92 mm).
“By increasing the engine’s stroke and redesigning the intake port shape, we optimized air and fuel flow to create more power while reducing emissions,” said Takahashi. “It’s part of our commitment to giving drivers more performance with less environmental impact.”
Armada’s engineers worked hard so drivers don’t need to, whether merging onto a highway or exploring a remote mountain trail. Plus, drivers have more power while enjoying enhanced fuel economy. It’s a win-win, and Nissan engineers are proud to stand behind it.
