Cadillac’s Elmiraj concept: a 500-hp, 21st-century Eldorado

For all the success Cadillac has enjoyed in recent years — reviving itself from a purveyor of slightly nicer Buicks into a credible challenger of German luxury makes — there's always been something missing from its showrooms. As good as its new smaller cars are, the most famous Cadillacs dominated the road, from the V-16s of the '30s to the last gasps of the '70s road yachts. Cadillac execs never say such cars are gone forever, but neither do they vow to revive their dinosaurs.

Today, Cadillac revealed the Elmiraj concept, a 500-hp coupe that harkens back to the past while offering, once again, a suggestion that the era of a full-grown Caddy could return — maybe.
