While the styling isn't drastically different from the CT4-V already out there, the front intake and openings look deeper and more aggressive. The middle, raised section of the hood is a little taller and the whole front-end design looks a lot like the one teased in Belle Isle. This vehicle even appears to have the same mirror design as the faster V.
The side sills, quad exhaust tips and wide rear tires lend this prototype an aggressive look, but we did note that it doesn't have the big ducktail spoiler we saw teased previously. Maybe Cadillac is trying to keep a low profile while testing. A keen eye will notice a wild apparatus attached to the front, which would serve as a great jousting pole if you were into that kind of thing.
We don't know exactly when Cadillac plans to introduce the faster V machines, but we wouldn't doubt if it happened before the year was out. The ATS-V and CTS-V didn't look wholly different than the pedestrian versions of those cars, and this prototype indicates Caddy may follow a similar pattern this time around. All will be explained from GM soon, but for now, we wait.
