Cadillac CT6

Cadillac's new flagship fits above the CTS and is priced to compete with the luxury-midsized crowd. This large sedan possesses some athletic chops and feels lively to drive. The firm ride is steady, controlled, and compliant, and the interior is very quiet. The base engine is a turbo-four, but most buyers will opt for the midlevel nonturbo V6; the top trim carries a 404-hp twin-turbocharged V6. The eight-speed automatic is smooth and responsive. All-wheel drive comes standard with the V6s. The interior is plush and roomy, but cabin storage is scant. Front-seat comfort is superb, but the rear seat is a bit short on thigh support. Despite improvements, the updated Cue infotainment system is still unintuitive. A plug-in hybrid version with an estimated 30 miles of EV range is also available.
