2016 Cadillac CT6 Twin Turbo Premium Luxury

The CT6 is Cadillac's full-size sedan, aimed squarely at the BMW 5 Series and Mercedes-Benz E-Class. It's a big sedan that feels lighter than it is, with quick steering and a chassis that stays composed on winding roads. The ride is smooth and quiet at highway speeds, though the larger wheels on upper trims firm things up a bit. Inside, you get a spacious cabin with comfortable seats and a trunk that's generous for a sedan. Its 3.0L V6 makes 404 horsepower and 400 lb-ft of torque, routed through eight-speed automatic and all-wheel drive, which gives it strong passing power without the V8 fuel penalty at 21 mpg combined. The adaptive suspension keeps the ride composed on rough pavement, though the 20-inch wheels transmit more road texture than the smaller ones on lesser trims.
