Cadillac is splitting its V strategy by adding lower-priced, lower-powered models to the traditionally high-performance name. The brand unveiled both the 320-horsepower 2020 CT4-V and the 355-hp CT5-V to media in Detroit.

A dyno test of the McLaren Senna shows the British supercar likely makes more horsepower than the brand's claimed 789 figure and certainly puts out more than the quoted 590 pound-feet of torque.
