DETROIT — Part of the mystique of the Dodge Viper is how the $87,000 supercar is made.

Each is hand-built by 64 hourly workers the company refers to as craftsman at a 400,000-square-foot plant just south of 8 Mile Road on Detroit’s Northeast side.

Unlike most auto plants that are visible from interstate highways, it’s easy to be a block or two away from the Conner Avenue Assembly Plant, which is tucked behind an extended-stay hospital, without even seeing it.

On Friday, FCA US — the company previously known as Chrysler — allowed the media to tour the plant for the first time in years. Inside, the gleaming polished floors, spacious work stations and wireless tools make for a plant that is vast and open and a lot quieter than typical automotive plants.

Here, each worker performs a range of tasks that the company says are comparable to what 150 different workers do at a normal assembly plant.

That’s possible because the pace is glacial compared with a normal assembly plant and the entire approach to building the vehicle is completely different from the mass-produced process used to make higher-volume cars.

At most modern assembly plants, finished cars pour off the line every minute. But at the Conner Avenue plant, it takes 2.5 hours for cars to cycle through the plant.

Over its 20 year history of making Vipers the the Conner Avenue plant has produced 24,000 of the cars. That is a volume that is tiny by almost any measure. FCA US sold more than 37,000 Ram pickups last month alone.

Tim Kuniskis, CEO of the Dodge brand, said the Viper was never intended to be sold in big volumes even though it has a big impact on the overall image of the company.

“You have a car like this because it has exponential impact on the marketing of the brand and the positioning of the brand,” Kuniskis said. “So even though you are only selling 750 cars, you have 3 million coming to your website, spending 10 minutes on your website where you have your other cars as well.”

But the fate of the plant and the Viper has been in question several times. The car, which debuted in 1992, was discontinued in 2010 in the midst of the Great Recession, causing the plant to be idled.

And last year, the plant was also idled for several months because sales of the Viper were slower than expected.
