Oldsmobile 442 W-30 Convertible

The 1970 Oldsmobile 442 W-30 Convertible was the most powerful Oldsmobile production ever created. The model is capable of developing 445 horsepower and 500 lb. ft. of torque. The W-30 was an option package on top of the 1970 Oldsmobile 442 model and some special features for the new model which included an engine capable of developing 5 extra horsepower. The only other supercar from those times to equal the maximum torque numbers is the 1970 Buick GS. The total production for W-30 convertibles in 1970 was 264 units. Few survived and still remain in the world today.

The 1970 was the most powerful production Oldsmobile ever created. Power of Oldsmobile 442 W-30 Convertible was increased from 370 hp to 455 what is really amazing for those who have experienced it is the 500 lb-ft of torque.
Unlike most engines of the postwar period, the Oldsmobile 455 is undersquare, i.e., the stroke is longer than the bore and because of that the engine tends to make the torque curve peak early in the rpm range; conversely, a short stroke engine will be inclined to rev higher and have higher torque peak. The advantage of an engine that has loads of torque at low rpms is that the surge of power is immediate from the moment that you step on the accelerator. While there are many cars from then to now that handily outperform the W-30 on paper, the number of cars that have that same sense of immediate power are far fewer and the result makes the W-30 an enormously fun car to drive on the street.
The W-30 was an option package on top of the 1970 Oldsmobile 442 model and some special features for the new model which included an engine with 5 more horsepower and an aluminum intake manifold, red fiberglass inner fenderwells, and fiberglass OAI hood.
The only other supercar of that era to equal the maximum torque numbers is the 1970 Buick GS. Even today, very few naturally aspirated cars match or exceed the 500 lb-ft of the 1970 W-30.
Always a relatively rare supercar, the total production for W-30 convertibles in 1970 was 264. (Of this number, 96 were manual shift and 168 were automatic. Of the latter, 126 featured the Hurst Dual-Gate shifter.) Few of these cars survived, and only a handful of authentic 1970 W-30 Convertibles remain in the world today
