2018 Cadillac CT6 vs. Its Competition

2018 Cadillac CT6

With the CT6, Cadillac is trying to go head-to-head with the finest large luxury sedans, returning to its “standard of the world” roots.

The Audi A8 has always been a small player in this niche, but its quotient of electronic features for both driver and passengers is high, not to mention twin-turbo V-8 power.

The BMW 7-Series is the largest sedan from the driver’s make, though driving it feels more remote than earlier generations, and it has its share of features and gadgets plus luxuriant interiors with custom trims.

The Lexus LS is conservative luxury; where the CT6 is brash, it’s muted, in a more sedate Japanese style.

The Mercedes S-Class is unquestionably the benchmark of the segment, and possibly the best volume car the 130-year-old German make has built.

With a wide selection of drivetrains and features, its fantastic interior cossets and assists all occupants.

A dark horse is the Tesla Model S, which competes on price if not interior space, and has probably stolen buyers from all the other cars in the group.

The all-electric sedan can be made stunningly quick, and today it’s the only practical electric car you can drive cross-country.
