2018 Cadillac CT6

Cadillac is primarily a luxury brand, selling quieter and higher-tech variants of Chevrolet vehicles. Its SUV line spans from compact options up to the enormous Escalade. Several boldly designed EV models have excellent range, quick acceleration, and fast charging speeds. There’s also the V-Series, a line of performance versions available for several vehicles, which can compete with the best sports sedans from Europe. Most models are available with excellent driver assistance tech, including GM’s Super Cruise. New car reliability across the brand is average. Several new models are Consumer Reports recommended for their interior quality, comfort, and fit and finish. We also recommend some of the brand’s used models.

Cadillac's new flagship fits above the CTS and below the BMW 7 Series and Mercedes-Benz S-Class. But it's priced to compete against the luxury midsized crowd. This large sedan possesses some athletic chops and has a steady, controlled ride and a very quiet interior. Most buyers will opt for the mid-level nonturbo V6, while 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 posh and roomy, but cabin storage is a bit scant. Despite improvements, the updated CUE infotainment touch screen is still unintuitive.
