It’s a sedan with more horsepower than a Hellcat, and that is awesome.
There's a lot to love about a good sleeper. It's just so much more satisfying to outrun someone who is absolutely convinced that he has the faster car. And the Chrysler 300 SRT-8 in the following video is an outstanding example of this. The 800-hosepower sedan is actually used as a daily driver (although, presumably without the big Hoosiers) and therefore must have plenty of opportunities to show up punks in STIs at the lights.
The SRT-8 is actually a pretty great sleeper right out of the box, but a Prochrager tends to make everything better.
