Back in 2003, Cadillac developed a concept car called the Sixteen that it proudly showed off at the Amelia Concours d'Elegance. Rumor had it that the Sixteen came very close to production, but for whatever reason, those plans were scrapped and the concept went back to gather some dust.

It's been 10 years since that time and apparently, Cadillac is getting ready to brush off the dust and bring the Sixteen back to the Amelia Concours d’Elegance. The automaker has given no indication as to why it’s bringing the Sixteen back, but don't be surprised if they're doing so to gather intel and feedback about the car in preparation for what could become Caddy's->ke18 next flagship sedan.

To refresh your memories, the Sixteen Concept was an extremely long car - 19 feet in length - that was powered by a ridiculous 13.6-liter V-16 engine that produced an astounding 1,000 horsepower. Its design, particularly the audacious vertical headlight setup, was eventually seen in a more recent Caddy concept, the 2012 Ciel.

The Sixteen's powertrain alone is enough to make people take notice. We just don't know how an engine with that much displacement will go over with the more environmentally aware population of today. But hey, Cadillac has long wanted a super luxury flagship in its lineup.

If they can do some tweaking here and there on the Sixteen, maybe it'll receive that production future it was supposed to get ten years ago.
