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.

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.

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.

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.

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.

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.

The Oldsmobile 442 was Oldsmobile’s entry in the “Supercar” wars of the mid-sixties and early seventies. Although it was never as lauded or as popular as the Pontiac GTO or Dodge Charger, it outlived many of its rivals and helped pave way for Oldsmobile’s ascendancy in the 1970s.
This week, we look at the history of the Oldsmobile Cutlass and 442.

The 1976 Cadillac Seville was Detroit’s first serious response to the growing popularity of luxury imports like Mercedes. Although it was an immediate hit, earning a handsome profit and inspiring numerous imitators, the Seville marked the beginning of the end of Cadillac’s credibility as a leading luxury car brand. This week, we look at the history of the 1976-1985 Cadillac Seville and the reasons for Cadillac’s subsequent decline.
