The Oldsmobile Toronado 1st Generation was built from 1966 to 1970.
History
The Oldsmobile Toronado was offered by the American car manufacturer General Motors under the brand Oldsmobile from autumn 1965 to mid-1992 front-wheel drive coupe of the upper class. The model was manufactured in four different series.
The model’s name is a term derived from the term tornado. When the Toronado was introduced in the fall of 1965, it differed in many ways from the then-usual offer in the US market. There was, on the one hand, the body shape of this large luxury coupé. In addition, the car was equipped with front-wheel drive. It was the largest front-wheel drive car ever built, and the first front-wheel drive car in America for almost 30 years Sharing the GM E platform introduced by the rear-wheel drive Buick Riviera in 1963 and adopted for the front-wheel drive.
A 7-litre, 385 b.h.p. Super Rocket V8 engine driving the front wheels? the Toronado is one of the biggest, fastest, quietest, most powerful and thirsty machines These things make it a very impressive car. With the 7.0-liter V8 reached a top speed of 217 km / h. Sceptics doubted whether the front-wheel drive made sense for such a big car, but the tests proved that the Toronado also had an above-average road holding compared to other American cars from that time. General Motors, like practically every other major manufacturer in the world, have been experimenting with front-wheel drive prototypes for many years. Everyone now recognizes the advantages of having the engine and transmission at the same end as the driving wheels whether they be front or back. Either way offers better traction, simplification in design The Tornado’s basic structure a three-quarter length perimeter sub-frame cloaked with an integral body customers want the Toronado, despite its radical engineering, it is still much like any other big American saloon to drive.

Also, the technology of the big Olds was unusual, torque converter and gearbox were connected with a unique chain drive. However, the space in the rear and the overview to the rear were somewhat limited by the sloping coupe form. The front seats, the rear bench has been moulded for only two people but there is comfortable room for a third

There is a rectangular theme for the instruments which are clustered in front of the driver and viewed through a steering wheel with four

A special option code called W-34 was available on the 1968 to 1970 Toronado. This included a cold air induction system for the air cleaner, a special performance camshaft and a "GT" transmission calibrated for quick and firm up-shifts and better torque . Dual exhaust outlets similar to the 1966–67 model years with cutouts in the bumper, were included with W-34. The models also had dual exhaust systems, but single hidden outlet running from the muffler exiting rearward on the right side. For 1970 only, the W-34 option also included special "GT" badges on the exterior of the car.
The W-34 Toronado was capable of 0–60 mph in 7.5 seconds and the standing 1/4 mile in 15.7 seconds at 89.8 mph (144.5 km/h).

separate front seats; cleaner air system; air conditioning system adjustable tilt of steering wheel; front disc brakes (diameter 11.30 in, 287 mm) 235R x 15 tyres; separate front seats, central selector lever; 55 Ah alternator
The car was popular with American car buyers. In 1966, more than 40,000 Tornados were sold. At the time it was technically one of the most impressive vehicles on the American market.
End of 1967 was a facelift, which approximated the shape of the Toronado with notchback and in the greatly enlarged grille integrated pop-up headlights the mainstream design in 1969, and the elimination of hidden headlights. The first-generation Toronado with the usual annual facelifts through 1970 The seven-Liter was replaced by a new 7.5-liter V8 with 375 or 400 hp. The deluxe model was renamed Toronado Custom.
In this form, the Toronado remained in production until the summer of 1970. Altogether 143.134 copies were made.
The Toronado shared drive technology with the Cadillac Fleetwood Eldorado, introduced in late summer 1966.
