Many years ago, you may recall hopping in grandpap’s Eldorado, Fleetwood, or Deville and taking a nice cushiony ride on the highway. When the Northstar engine came about in the mid-1990s we all started to see Cadillacs->ke18 actually putting out some respectable performance numbers to go along with their couch-like ride. The lid started coming off of the Cadillac performance sedans in 2003, when the automaker released the CTS->ke1200. In 2004, when the 400-horsepower CTS-V came out, all hell broke loose.

By the 2012 model year, the CTS-V had morphed into a 556-horsepower, supercharged sub-supercar. For some people, however, 556 horsepower just isn’t quite enough. This is where the Cadillac tuners at D3 come into play, literally. They took two CTS-Vs and converted them into 1,500-horsepower supercars that are primed to bring havoc upon any road they are on.

So what does D3 do? They hand the keys to INDY Car driver J.R. Hildebrand and Formula D driver Tyler McQuarrie, of course! These two racers took these 1,500 horsepower luxury cars down to the Long Beach street circuit and stretched out these Caddy’s legs a little.

By stretching their legs we mean smoldering the tires to oblivion and getting it on video (above). The tire smoldering and supercharger whining is aplenty in these videos, but there is one thing that is slightly more impressive. An amateur video was also released that showed the cameramen filming these two Caddys and watching these dudes put their bodies at risk just to get a good shot. That takes a rather big brass set, if you ask us; an even bigger set than playing with a few CTS-Vs on ‘roids.
