This Day in Automotive History: April 21

GM produces its 100,000,000th vehicle (1967)

Janesville, Wisconsin earned its place in automotive history on this day in 1967 when a 1967 Nantucket Blue Chevrolet Caprice Custom Coupe rolled off an assembly line there, becoming the 100,000,000th General Motors vehicle ever produced. This Caprice, which retailed for $3,078 and had a 395 ci V8 engine that put out 275 horsepower, marked a milestone no other car company had achieved to this date. But was this really the one hundred millionth GM vehicle?

C4 Corvette Debuts (1983)

A dramatic transformation of America’s sports car arrived when Chevrolet Corvette C4 was introduced on April 21, 1983 as a 1984 model. Developed by Chevrolet, the C4 represented the first complete redesign of the Corvette since 1968, bringing with it a sleek, angular body, advanced aerodynamics, and a focus on handling and technology. Featuring a digital dashboard and a new chassis, the C4 marked a shift toward a more modern, performance-oriented Corvette, helping the model stay competitive in an evolving global sports car market.

There is famously no production 1983 model year Chevrolet Corvette. During development, General Motors faced delays related to quality control, emissions compliance, and final engineering refinements for the all-new C4 platform. As a result, the company chose to skip the 1983 model year entirely and launch the redesigned Corvette as a 1984 model instead. However, one exception exists—a single pre-production 1983 Corvette was saved from destruction and is now preserved at the National Corvette Museum, making it one of the rarest Corvettes ever built.

Zora Arkus-Duntov, the “Father of the Corvette,” Passes Away (1996)

The legacy of the Corvette lost its most influential champion when Zora Arkus-Duntov passed away on April 21, 1996, at the age of 86. Often referred to as the “Father of the Corvette,” Duntov was instrumental in transforming the car from a stylish cruiser into a true performance machine and even pushed for it to be a mid-engine car, long before the C8. His engineering leadership at General Motors helped introduce innovations like fuel injection and racing development that elevated the Corvette to world-class status. His impact continues to shape the identity of the Corvette to this day. Check out this must read book about Zora Arkus-Duntov.

Fiat Becomes Majority Owner of Chrysler (2011)

A major shift in the global automotive landscape took place on April 21, 2011, when Fiat announced it would increase its stake in Chrysler to a majority share. The move followed Chrysler’s recovery from bankruptcy and marked a deepening partnership between the Italian and American automakers, eventually forming Fiat Chrysler Automobiles (FCA). That partnership would evolve even further a decade later—on January 16, 2021, FCA merged with France’s PSA Group to create Stellantis, one of the largest automakers in the world. Today, Chrysler operates as a brand within Stellantis’ global portfolio, alongside names like Jeep, Dodge, Peugeot, and Maserati, reflecting the increasingly international nature of the modern auto industry.

VW Assembles One Millionth Atlas at Chattanooga, TN Facility – 2026

Volkswagen announced that the one millionth VW Atlas SUV rolled off the assembly line of its Chattanooga, Tennessee assembly facility on this day in 2026. VW began Atlas production there in 2016 and the figure includes the Atlas Cross Sport, which started rolling down the line in 2019. “Producing one million Atlas vehicles is a milestone our entire team shares. It reflects years of passion and a commitment to quality,” said Henning Habicht, head of Volkswagen Chattanooga operations. “It also speaks to the trust families place in Atlas and our focus on building vehicles that fit their lives.” The announcement also alluded to an all-new Volkswagen Atlas arriving in the fall of 2026. Of course, the Atlas still has a ways to go to outsell the iconic Volkswagen Beetle.
