Prototypes FORGOTTEN: Cadillac Sixteen, the “superberlina” of V16
For Cadillac, the last decade has been a real race to stay as the luxury manufacturer has been over a hundred years without forgetting to be competitive in the industry of the XXI Century. To achieve the objective General Motors proposed to renew the aesthetics and technology of their vehicles and take advantage platforms group to start its expansion into other markets such as Europe or China.
Along the way there were some prototypes that have served to define the lines of recent models such as the CTS or STS. Prototypes, without going any further, as the Cadillac Sixteen featured in 2003. It could be defined very quickly as an innovative technology for the chassis and brutal but relatively efficient due to its huge engine 16 cylinder vee to speak next artwork for its aesthetics.
It was about one stylized four-door sedan and huge dimensions, about six meters and more than two and a half tons. His aesthetic was bursting with extremely long hood, short stature, elongated headlights, its giant front grille or bonnet opening system in two wings. The chassis is based on an aluminum with a central tube and exhaust housed transmission and link served for body structures, roof, hangers ...
However the most impressive was its engine. A 16 cylinder vee 13,600 cm3, 1,013 hp and 1356 Nm of torque, not enter any brand plans (except Bugatti and a few others) for obvious reasons: cost, fuel consumption, emissions, weight ... But surprisingly Cadillac and got in 2003 a mechanism that could standardize little more 14 liters / 100 km, consumption saloons similar to that made by that time.
Its efficiency was due among other things to modular design allowing mechanical operation in four cylinders in full cruise quiet road use eight cylinders when more power was required (for example, overtaking) and leverage sixteen cylinders for our most primal impulses run wild with the throttle.
Mechanical consisted of cylinders with two valves and 850 cm3 each. Therefore it circulating in the effective four-cylinder engine total was only 3,400 cm3. Its creators showed that on a trip between Detroit and California would be able to travel 65% of the time in eight cylinders, 30% of the time in four-cylinder and only 5% in sixteen cylinders.
By the way. In 1930 Cadillac became the first manufacturer who developed a 16-cylinder engine and started mass production. It was based on two V8 engines and the recipient States was the Cadillac Fleetwood.
