Imagine a 5,000 lb sedan… how would it move? Ask Cadillac and they’ll respond with the engine in this concept, which is a 1,000 hp 13.6L V16. The Cadillac Sixteen concept was brought to life with the intention of bringing back the American automaker’s 16-cylinder ultra-luxury sedans from the 1930s. Of course, the Sixteen wouldn’t work in today’s fuel-conscious world with a normal V16, so Cadillac incorporated an active-cylinder deactivation system that would turn off 12 of the cylinders during light driving, eight cylinders in harder driving, and would fully unleash all 16 cylinders under full acceleration.
Even though the Cadillac Sixteen was shelved, there are still rumors of a new Cadillac flagship sedan, that might reference the Sixteen. Design-wise, Cadillac seems to be looking to the Sixteen concept as inspiration, with its eccentric wheel arches and bling-y grille hitting the new Cadillac ATS and XTS sedans.
