This Frontier V6 Survived 300 Hours at Redline-Now It's Nissan's 20 Millionth Engine
A Tough Naturally Aspirated V6
The Frontier's V6 isn't new, but it's earned its stripes the hard way: by taking a beating and coming back for more. Nissan put the 3.8-liter V6 through brutal tests before it ever saw a customer, including running it flat-out at redline for 300 hours straight just to see what would break.
This engine is built in America, and now it's the face of a big milestone for Nissan. The 20 millionth engine from Decherd is a VQ-ZV9 V6, and it's going straight into a Frontier – one of Nissan's toughest trucks getting one of its toughest engines.
Nearly Three Decades of Engine Building
Decherd opened its doors in 1997 and has been cranking out engines ever since. It's one of Nissan's oldest US plants and supplies powertrains for vehicles all over North America.
Nissan has poured about $2 billion into Decherd over the years, out of a $14 billion investment in US manufacturing. So this isn't just another engine plant – it's a key piece of how Nissan builds cars for North America.
David Sliger, vice president of Regional Powertrain Operations for Nissan Americas, said the 20-million-engine milestone reflects more than output numbers. According to him, it represents the craftsmanship and long-term dedication of the workers in Decherd, many of whom have spent much of their careers there.
The plant isn't just about engines. It supports jobs all over Tennessee, especially in Franklin County, and has become a fixture in the local community. Some families have had more than one generation working there, which gives the place a real hometown feel.
Preparing for the Next Phase
Even as the 20 millionth engine is a classic V6 for a truck, Nissan is already thinking about what comes next. Nissan's US production has jumped from 40 to 60% in just a year, with a goal of hitting 80%. The idea is simple: build more cars where people actually buy them.
That means Decherd isn't just about gas engines anymore. The plant is gearing up to build both traditional and electrified powertrains for future Nissan and Infiniti models in the US – including the upcoming Xterra, which will get a V6 Hybrid.
