D3 Cadillac CTS-V Battlewagon

Yes, the 2011 Cadillac CTS-V is fast. So fast it makes our heads spin just thinking about it. So fast that lesser cars go home and cry to their mommies. So fast it's gone plaid. Better still, it can be purchased in sedan, coupe and, our particular favorite, wagon bodystyle.

But what happens when you take the CTS-V Wagon-shaped dial and turn it up to 11? To find out, current Motor Trend scribe and Autoblog alumn Jonny Lieberman turned to the tuners at D3, who served up a healthy dose of its so-called Battlewagon.

Fitted with a host of goodies like a new pulley driving the supercharger, a larger intercooler and a reflashed computer, the D3-tuned CTS-V makes 675 horsepower (or more...) and is therefore expected to be more than a hair bit quicker than its stock counterpart. But just how much faster is it?
