The 1969 Opel GT was Opel’s first show car and the German company’s first two-seat sports car since before World War II. Based on the humble Kadett B and often considered a miniature Corvette, the GT also owed a great deal to Chevrolet’s compact Corvair and a concept car once intended to replace the ‘Vette. In this installment of Ate Up With Motor, we take a look at the origins, history, and fate of the 1969–1973 Opel GT and its various planned successors.

Pillarless Pioneer: The 1949 Buick Roadmaster Riviera
In mid-1949, GM’s senior divisions introduced a trio of glamorous new models — the Cadillac Coupe de Ville, the Oldsmobile Futuramic 98 Deluxe Holiday coupe, and the Buick Roadmaster Riviera — that are popularly, if incorrectly, considered the first pillarless hardtops. This week, we consider the origins of this quintessentially (though not uniquely) American body style, examine the development of the the 1949 Buick Roadmaster Riviera, and consider the origins of the hardtop coupe.

This Time, It’s Personal: The 1967-1970 Cadillac Eldorado
The 1967 Cadillac Eldorado is a milestone Cadillac by any standard. Rakish, sophisticated, and surprisingly sporty, it was the division’s first front-wheel-drive car and its first serious entry in the burgeoning personal luxury genre. This week, we explore the story of the first FWD Eldorado.
Author’s note: An earlier version of this article first appeared in August 2009. We’ve completely rewritten and expanded it, clearing up some errors and misconceptions and adding new information and new images.

Out in Front: The Front-Wheel-Drive Oldsmobile Toronado, Part 2
Most histories of the Oldsmobile Toronado start and end with the original 1966 models, but that wasn’t the end of the story. The Toronado survived another 25 years and its most commercially successful period was still to come. This week, we look at the history of the 1971-1992 Toronado and examine another vehicle that shared its novel powertrain: the 1973-1978 GMC Motorhome.

Contrary Compact: The Life and Death of the Chevrolet Corvair
There is no American automobile more controversial than this one. It’s the car that launched the career of Ralph Nader and led directly to the passage of the first U.S. federal safety legislation. Automotive historian Michael Lamm called this car a martyr; others said it should never have been built at all. It was flawed, at least in its original iteration, but it was also one of the most daring cars GM has ever built. We’re talking about the Chevrolet Corvair.
Author’s Note: The original version of this article was written in 2007. It has been extensively revised and expanded, adding new information and correcting various factual errors. WARNING: The article contains animated GIF images.

Wide Track: Bunkie Knudsen, Pete Estes, and the Pontiac Renaissance
In 1956, GM’s Pontiac Motor Division was close to death, its sales down, its market share declining, and its image at a low ebb. That summer, however, help arrived in the form of Bunkie Knudsen, Pete Estes, and John DeLorean. Together, they lifted Pontiac out of its mid-fifties doldrums and put it on track for its unprecedented success in the 1960s. This week, we look back at the reign of Bunkie Knudsen and the birth of the legendary Wide Track Pontiacs.

Oscar Banker, the Automatic Safety Transmission, and the Art of Research
We’re going to take a different approach for this week’s article. Instead of presenting another history, we’ve decided to give you a look at the way we approach the research for these articles, and tackle a challenging comment posed by one of our readers: did inventor Oscar Banker design the 1937-1939 Oldsmobile/Buick Automatic Safety Transmission, the predecessor of Hydra-Matic?
Important author’s note: Much of this article, originally written in 2010, was speculative and thus many things turned out to be off-base or wrong. I’ve opted to leave the article up for the time being (having removed some of the more glaring errors) until such time as I can more thoroughly revise it, but please keep in mind that this is NOT an authoritative piece on Oscar Banker. Caveat lector!

Wouldn’t You Really Rather: A Brief History of the Buick Gran Sport
The words “sporty Buick” have never quite rolled off the tongue, but over the years, Buick has produced a surprising number of performance cars, from the speedy prewar Century to the turbocharged Grand National and GNX. From 1965 to 1975, it even offered its own entry in the burgeoning Supercar market: the Skylark Gran Sport. This week, we take a look at the history of Buick muscle and the career of the Skylark Gran National, GS400, GS455, and GSX.

Dynaflow, Turboglide, Roto Hydra-Matic, and Other Early GM Automatics
The Hydra-Matic, GM’s first fully automatic transmission, was a great success, inspiring a host of rivals — including some within General Motors itself. In this installment of Ate Up With Motor, we look at the origins of Dynaflow and Powerglide, the ambitious but ill-fated Turboglide and Flight Pitch Dynaflow (a.k.a. Triple Turbine), the later Controlled Coupling Hydra-Matic and Roto Hydra-Matic, and more.
AUTHOR’S NOTE: This article, originally written in 2010, has been extensively revised and expanded for 2016.

Hydra-Matic History: GM’s First Automatic Transmission
GM’s original Hydra-Matic transmission was one of the most important innovations in the history of the automobile. It wasn’t the first automatic transmission, but it was the first one that really worked and its resounding commercial success paved the way for every subsequent auto-shifter. This week, we take a look at the origins of the Hydra-Matic and its originator, Earl Thompson, who also developed the first Synchro-Mesh gearbox back in the 1920s.

Cammer: The Pontiac OHC Six
With all the furor surrounding Ford and Chevrolet’s new 300+ horsepower V6 Mustang and Camaro, you would think hot six-cylinder engines were a new idea, at least in America. Not so — in 1965, about a decade after the demise of the Hudson Hornet and its “Twin H-Power” straight six, Pontiac introduced a sophisticated new overhead cam six-cylinder engine that promised V8 power and six-cylinder economy. This week, we look at the short life of the 1966–1969 Pontiac OHC six, Pontiac Firebird Sprint, and Tempest Le Mans Sprint.

George Hurst and the Hurst Olds
In our history of the Oldsmobile 442, we mentioned that it was not exactly the leader of the pack when it came to Supercar performance. To rectify that problem, Oldsmobile joined forces with Hurst Performance Products to create the ultimate high-performance Oldsmobile: the fearsome 1968 Hurst Olds. This week, we look at that car and the subsequent H/Os, a series that ran through 1984.
