Don't let that modified Chevrolet Caprice body fool you, this car is about four to six inches longer than Chevy's US-spec cop car, from the A-pillar forward. According to our spy, with the Caprice at 203 inches and the concept at 205, adding a few extra inches here and there fits the bill for the four-door Elmiraj that was hinted at in Jay Leno's Garage.
There are a number of other classic mule signs on this car, including a cover over the fuel door and heavily modified front and rear fascias, each of which serves to hide some significant change from the standard Caprice. Using a Caprice for development also, hopefully, hints at something that big Cadillacs like the XTS have lacked - rear-wheel drive.
This is quite an exciting development for Cadillac fans. A new flagship, with a stylish, four-door-coupe body that will take aim at the Mercedes S-Class is something that Caddy enthusiasts have been begging for. With a debut set for sometime in 2015, though, there's still plenty of waiting and a lot that can change. Watch this space.
