Cadillac STS vs. Cadillac DTS Review

Utility
Drivers with frequent child-duty might favor the Cadillac DTS over the Cadillac STS.

Dimensions
The DTS is considerably heavier than the STS. The Cadillac STS's tank is about the same size as the Cadillac DTS's, though the Cadillac DTS's is a little larger. The STS and the Cadillac DTS compete for the same parking spaces.

Convenience
The Cadillac DTS's fuel tank will need to be replenished somewhat more often than the unit in the Cadillac STS.

Cost
The destination charge is a standard charge for transporting the vehicle from its point of origin to the dealer. It costs approximately the same to get the STS to the dealership as the DTS. The Cadillac STS will save you money at the pump compared to the Cadillac DTS. In terms of fuel economy, the STS beats the Cadillac DTS. In terms of MSRP, the Cadillac DTS doesn't cost much less than the Cadillac STS.

Handling
With its tighter turning circle, the STS is most certainly nimbler than the Cadillac DTS, something to consider if you do a lot of city driving; on the other hand, note that a vehicle with a tight turning circle may feel a bit twitchy on the highway.

Drivetrain
The Cadillac STS's engine is considerably smaller than the Cadillac DTS's. Bear in mind that a smaller engine usually has to work a little harder; on the flip side, smaller engines are often cheaper to fix. The STS has no lessons to learn when it comes to torque from the Cadillac DTS.

Comfort
While the front cabin in the DTS offers a bit more head room than the STS, there honestly isn't much of a difference. The ampler interior dimensions of the DTS make it more spacious for your passengers than the Cadillac STS.

Warranty
The DTS and the STS have the same basic after-sale protection.
