2019 Cadillac CT6 vs. 2019 Lexus LS

The 2019 Cadillac CT6 and the 2019 Lexus LS are two beautiful high-end sedans with great features ensuring their appeal is more than skin-deep. But, which one should you drive home from the dealership? Our side-by-side comparison should help you decide.

Luxury & Convenience

Brands like Lexus are renowned for their luxurious touches, and the maker doesn’t disappoint with the LS. Art Wood trims and Kiriko cut glass make it look more like a work of art than a car. Ergonomically-designed seats cushion your body while seven massage settings will help you feel your best, even on long road trips. The infotainment system’s Apple CarPlay connectivity will excite iPhone users, although Android fans are left out in the cold. The Mark Levinson reference surround sound system is perfect for your own rendition of carpool karaoke.

While Lexus has included an impressive range of features, it forgets some basics like oil pressure and temperature gauges. These little conveniences help you identify minor problems before they become major ones. Cadillac’s optional automated parking system is another convenient feature missing from the LS. The 2019 CT6 has a new Rotary Infotainment Controller, which lets you control your tunes, temperature, and connected apps with ease.

The CT6 isn’t just about practicality, though. Upgrade your trim for the most comfortable, adjustable leather seats with heating, ventilation, and massage controls. No one needs a 34-speaker Bose Panaray audio system, but if you love music, its inclusion is a major selling point.


Cars like the Lexus LS always deliver superior handling on the road. Just like other cars from the maker, it’s stable around corners and smoothes for your comfort, seeming to glide along the road. Cadillac doesn’t have such a strong reputation in this department, but the Cadillac CT6 is surprisingly capable.

While the cars handle similarly, the Cadillac’s engines are more powerful. Both makers offer a variety of different motors, but experts agree the CT6’s 3.0-liter turbocharged V6 and the LS’s 3.4-liter turbo V6 are the closest. Despite being much smaller, the Cadillac’s motor generates 404 horsepower and 400 pound-feet of torque. This isn’t too much less than the larger Lexus engine, which generates 416 horsepower and 442 pound-feet of torque. With a lighter, more efficient engine, the Cadillac reaches 60 mph from standing in five seconds, 0.3 seconds faster than the Lexus.

The 3.4-liter turbo V6 is also the LS’s most powerful engine. Cadillac goes one better, offering an optional V-Sport 4.2-liter turbocharged V-8 which creates 550 horsepower and 627 pound-feet of torque.


Both vehicles have airbags for drivers and passengers, four-wheel antilock brakes, electronic stability systems, rearview cameras, lane departure warning systems, and a host of other safety features. But the CT6 has a few key additions that give it the edge. Its pre-tensioning seatbelts sense rear collisions, not just front ones, to guard against whiplash. Parents take comfort in the rear seat reminder which can save little lives. Its optional infrared night vision system lowers the risk of hitting animals, pedestrians, and other obstacles when night falls.

While the 2019 Lexus LS is a quality sedan, this Japanese car can’t quite reach the high bar Cadillac has set with the CT6. Both are quality vehicles, but the American automobile has a slight advantage over its Asian rival.
