Overview

The 2019 Cadillac CT6 is a midsize sedan offered in 5 trims, starting off at a base MSRP of $50,495. For that price, it mainly competes with the BMW 5 Series, the Genesis G80, and the Lexus GS 350. Between 4 trims, the CT6 offers 4 powertrains. The base engine is a 2.0L turbocharged Inline-4 capable of making 237 horsepower and 258 lb-ft of torque. If more power is required, there is also a 335 horsepower-making 3.6L V6 engine. Furthermore, a 3.0L Twin-Turbo V6 and 4.2L Twin-Turbo V8 are also available with 404 horsepower and 500 horsepower respectively. All three engines are mated to a 10-speed automatic transmission. The CT6 reaches 60 MPH from zero in 6.4 seconds on its base engine, which gets pumped up to 4.4 seconds with the 4.2L twin-turbocharged V8 respectively. Depending on the powertrain, the CT6 can manage a combined fuel economy between 17 and 28 MPG. While we're on the topic of choices, the 9 striking colors the CT6 comes in really pull you towards itself.
