2020 CADILLAC CT5 V TEST DRIVE BY CAR CRITIC STEVE HAMMES. Cadillac’s car lineup has been reduced to 2 all-new models, the compact-sized CT4 and this; the midsize CT5, both available in mid-performance models Cadillac refers to as V-Series.  
 With a twin-turbo V6, MagneRide suspension, Brembo front brakes, an electronic limited slip differential, V Drive Mode, Launch Control and Performance Traction Management, this V-Series injects enough raciness into the CT5 to satisfy all but the most demanding drivers.  And for them, the Blackwing variant arrives next summer.
