Once a star of America's biggest car shows, Mercedes-Benz is now abandoning them, one by one.

The German luxury maker plans to skip next year's New York auto show, after having been a central figure at the influential luxury-leaning consumer event for at least four decades. It is part of a bigger move by Mercedes — and one also being made by other brands around the world. In recent years, Mercedes also has dropped out of the premier U.S. auto shows in Detroit and Chicago. Only its presence at Los Angeles continues among the Tier 1 American events. But even that commitment could be in doubt.

A Mercedes spokesman noted last week it is too early to say whether the brand will attend the 2020 Los Angeles Auto Show.

The exit from New York could foreshadow Mercedes' rejection of the auto show business model entirely, as the company focuses on digital and retail-based ways to engage with customers. A Mercedes spokeswoman cited the automaker's desire to launch new products through nontraditional marketing methods to create brand awareness and engage shoppers.

Mark Scheinberg, New York International Auto Show president, said he hopes Mercedes' exit is temporary. "We don't know what their long-term plans are. Brands change their marketing strategies. Hopefully, next year, we'll hear back from them."

But Mercedes joins German rival BMW, which last year walked away from the New York show, despite the Big Apple being one of the biggest luxury-vehicle markets in the U.S.

A BMW spokesman said the brand's decision to leave the New York show was part of a "strategic shift to invest more in experiential events rather than static displays."

But pulling out of the New York show, which attracts more than 1 million attendees annually, is a "blow" for Mercedes' dealers, Scheinberg said.

"The response from the dealers when they heard that Mercedes is going to bypass the show was pretty strong," he said. "They thought it didn't make a lot of sense."

Seventy-two percent of attendees at the 2019 show expressed interest in buying a vehicle in the next 12 months.

Skipping New York is a mistake for Mercedes, given the large presence there of other luxury brands, such as Audi and Lexus, said one East Coast Mercedes dealer who requested not to be identified.

"When you've got the competition present at a show and you're absent, that's a black eye," the dealer said.

Sam Fiorani, vice president with AutoForecast Solutions, said that decisions to leave car shows are shortsighted since the shows are one of the few places for aspirational buyers to experience vehicles they were not necessarily aware of.

"Where else can you get that kind of direct experience with potential customers?" Fiorani said.
