The 2022 Cadillac CT4 V Blackwing is what happens when a wallflower sedan gets infused with superpowers. The twin-turbo V6 belts out 472 horsepower. The Brembo brakes will stop a train. And when it’s not slicing up a track, the Blackwing is a docile grocery getter. All of that and it’s available with one of the best manual 6-speed transmissions on the planet (or choose a 10-speed automatic). Tom Voelk checks out a well-equipped V Blackwing on an empty backroad and finds General Motors doesn’t get credit for it’s excellent chassis tuning.
