The 2018 Cadillac CT6 Sedan is a midsize sedan offered in 4 trims, starting off at a base MSRP of $54,095. For that price, it mainly competes with the Audi A6, the Volvo S90, and the BMW 5 Series. Between 4 trims, the CT6 offers 3 powertrain options. The base engine is a 2.0L turbocharged inline 4 capable of making 265 horsepower and 295 lb-ft of torque. If more power is required, there is also a 335 horsepower-making 3.6L V6 engine available on higher trims. There is also a 3.0L turbocharged V6 available for purchase and this engine puts out a decent 404 horsepower. All three engines are mated to an 8-speed automatic transmission. 

The CT6 reaches 60 MPH from zero in 6.4 seconds on its base engine, which gets pumped up to 6.1 seconds with the 3.6L engine. These impressive times further drop to 5.6 seconds on the turbocharged V6 motor. Depending on the powertrain, the CT6 can manage a combined fuel economy between 21 and 25 MPG. While we’re on the topic of choices, the 11 striking colors the CT6 comes in really pull you towards itself.
