Callaway Gives Cadillac’s V8 Muscle Sedan A 780-HP Sendoff

Be forewarned. The next time you see a Cadillac CT5-V Blackwing on the road that seems a little bit meaner than standard, it might be one of these. Callaway Cars has just revealed the 780 horsepower SC780, an even more monstrous version of Cadillac’s ultimate muscle-sedan. It may not stand out in the crowd, though, until it rips away from you at breakneck speed.
