In 1962, Chevrolet and Oldsmobile introduced the world’s first turbocharged production cars, the Oldsmobile F-85 Jetfire and Chevrolet Corvair Monza Spyder. In this installment of Ate Up With Motor, we’ll discuss the origins of turbocharging, the development of the Oldsmobile Jetfire, and the turbocharged Corvair that nearly stole its thunder.
What price novelty? If you walked into a Pontiac dealer in November 1960, the answer was $2,167, the list price of one of the most unusual American cars of its era: the all-new 1961 Pontiac Tempest. In this installment of Ate Up With Motor, we’ll take a look at the short career of the “rope-drive” 1961–1963 Pontiac Tempest and the hows and whys of its peculiar front-engine/rear-transaxle powertrain.
Hard as it is now to envision, there was a time, still within living memory, when trucks were not readily accepted in American polite society. One of the most significant harbingers of the transition to our modern era of pampered, luxurious utility vehicles was this rare truck: the 1955 to 1958 Chevrolet Cameo Carrier (and its even rarer brother, the GMC Suburban Pickup).

Although the Hydra-Matic transmission was first used by Oldsmobile and Cadillac, the final user was not a GM division, but Rolls-Royce, which used its own license-built versions of this highly successful GM transmission from 1953 to 1978. This included an unusual, short-lived variation for the early Rolls-Royce Silver Shadow and Bentley T-Series — the last iteration of the original Hydra-Matic transmission. In this installment of Ate Up With Motor, we take a look at the upper-crust British career of this venerable American automatic transmission.

If you’re familiar with transmissions like the Chrysler TorqueFlite and GM Turbo Hydra-Matic (among others), you may have heard of the “Simpson gearset.” In this installment of Ate Up With Motor, we look at the origins and function of the Simpson gearset and briefly introduce you to its inventor, the late Howard W. Simpson.

Fluid clutches — fluid couplings and torque converters — have many advantages for automotive transmissions, but with those benefits comes a cost: fuel-wasting hydraulic slippage even at cruising speed. Since the 1940s, automakers have come up with a variety of strategies for reducing or eliminating that slip, including series parallel “split torque” transmissions and different types of converter lockup clutches. In this installment of Ate Up With Motor, we take a look at how GM, Ford, Chrysler, Packard, and Studebaker have approached this slippery problem from 1949 through the late eighties.

Although frequently misunderstood and often misspelled, MacPherson struts are one of the most common suspension systems used on modern cars, found on everything from the Proton Savvy to the most formidable Porsche 911 Turbo. In this newly revised and updated installment of Ate Up With Motor, we’ll take a look at the origins and workings of the MacPherson strut, including modern variations like the Toyota Super Strut, GM HiPer Strut, and Ford RevoKnuckle.

It occurred to us recently that while we’ve written about the 1963-1965 Riviera and the controversial 1971–1973 “boattail,” we keep skipping over the second generation of Buick’s sporty personal luxury coupe. However, the second-generation Riviera outsold its predecessor and its successor combined — also dispatching its groundbreaking Oldsmobile Toronado cousin for good measure. In this installment of Ate Up With Motor, we take a closer look at the 1966 Buick Riviera.
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.

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.
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.

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.
