The Cadillac Sixteen Concept debuted at the Detroit Auto Show in 2003. The car is a modern tribute to the Cadilac Sixteen that was produced from 1930-1940. The Sixteen was Cadillacs top of the line model. The car was made to order and extremely expensive to purchase. Just over 4,000 Cadillac Sixteens were produced during the 11-year production run.
We came across this 1930 V-16 Phaeton at the Atlanta Concours d’Elegance. It has a 7.4L 452 cubic inch engine that produces 165 horsepower. Cadillac was the first manufacturer to have a V-16 powered production vehicle.
The 2003 Cadillac Sixteen concept looks like a modern-day luxury sedan. The car has a 4-wheel steering system called The Quadrasteer™. At low speeds, The Quadrasteer™ allows the car to have a tighter turning radius. At higher speeds, the rear and front tires steer at the same time for superior control and stability.
The interior featured a rear-seat DVD information system along with other goodies.
The monster 829ci/13.6 liter V-16 produces 1000hp and 1000ft_lbs of torque. The 32V motor features displacement on-demand technology. Following the introduction of the 2003 Sixteen Concept, this technology debuted in 2004 for upcoming models. Displacement on-demand technology is a fuel-saving system which allows the ECU to shut down cylinders during normal driving situations. When the accelerator is pressed “the off cylinders” will come back online to meet the power demands.
Some may assume that this motor was engineered by putting two production V8’s together. Actually, this engine was designed by Katech Inc. exclusively for the Sixteen Concept.
The engine is mounted to an electronically controlled 4-speed automatic transmission. Since the car is experimental, the top speed is restricted to just 40 mph.
