2011 Cadillac STS Interior Review

Note: This interior review was created when the 2011 Cadillac STS was new.


Interior: 7.3

In a class that’s lead by cars with handsome, well-crafted interiors, the 2011 Cadillac STS falls short. The use of some hard plastics and confusing controls make the STS’ cabin less luxurious than competitors who outfit their cars with opulent, soft-touch surfaces at the same price point. Seating accommodations also earn mixed reviews, and the STS’ trunk is not quite large enough to offer a competitive amount of space for cargo.

  • "Minor demerits include the use of some low-grade plastic trim pieces that you won't see in competing luxury sedans." -- Edmunds 
  • "Road and wind noise are both well muted. The new V6 sounds refined when accelerating and is otherwise quieter than the engine it replaces." -- Consumer Guide
  • "The good fit and finish remains and luxury buyers should be pleased with this Cadillac's generally high-class ambience." -- Edmunds


Reviewer opinion about the seats in the 2011 Cadillac STS is mixed – some claim that they aren’t supportive enough, while others find them too firm to be comfortable. Up front, reviewers consider the STS to have ample room for most adults, but they say the back seat doesn’t offer the amount of space you’d expect from a car this size.

  • "Disappointing for a car this large. With the front seats set far back, leg room is limited and toe space is tight. The seat itself is well contoured and offers good back support, though a longer seat bottom would enhance long-distance comfort. Headroom is just adequate." -- Consumer Guide 
  • "Sporty front seats might be too firm for some posteriors." -- Edmunds 
  • "The STS seats show Cadillac has found a nice combination of comfort and support, and they do a good job of holding you in place without being too firm." -- Kelley Blue Book 
  • "The front seats have plenty of range for different-sized drivers, and the leather upholstery is both supportive and well-cushioned." -- Cars.com

Interior Features

The base 2011 Cadillac STS isn’t exactly packed full of standard interior features. An eight-speaker Bose CD audio system, dual zone climate control, cruise control, power-adjustable front bucket seats and rear parking assist round out the base model’s standard equipment list. For about $3,500 more, the Luxury trim is more competitive, adding an in-dash CD changer, wood trim, heated and ventilated front seats, a heated steering wheel and Bluetooth phone connectivity. Navigation is also optional on STS models in Luxury trim, but not available on the base.

For $9,100 more than the base model, the Premium trim includes all the aforementioned features, but also throws in standard navigation and a Bose 5.1 Surround Sound audio system. However, shoppers looking for an all-wheel drive model will find that only base and Luxury models are available with all-wheel drive.

The STS is available with all the interior tech that you’d expect, but some reviewers note that the controls are confusing compared to top rivals such as the Infiniti M. Sub-par materials are also noticeable in some areas, leaving the Cadillac STS with an interior that feels less refined than other luxury large cars.

  • "The controls are straightforward and easy to use, with the exception of the confounding memory-setting procedure for the driver seat, mirrors, radio and climate controls. Unlike traditional systems, which place buttons on the door or driver seat, you must dive deep into the navigation touchscreen to set memory functions. It's frustrating, but at least it's something done only occasionally." -- Edmunds
  • "Unfortunately, nobody thought to soften the edge of the center console, which still bruised our knees after just a few hours of driving." -- Car and Driver
  • "All controls are easy to reach, though some markings are confusing." -- Consumer Guide 
  • "Certainly pleasing to the eye, but not ground-breaking by any means." -- Kelley Blue Book 
  • "The dashboard and center controls sport the same edgy contours that characterize the outside." -- Cars.com


With just 13.8 cubic feet of space for cargo, the STS’s trunk space is easily beaten by other cars in the class. If you need a bigger cargo hold in your next luxury large car, look to the Cadillac DTS, Lincoln MKS or Mercedes-Benz E-Class for a more spacious trunk.

  • "The trunk is also a bit small, with 13.8 cubic feet of total capacity." -- Edmunds
  • "Trunk space is unexceptional for STS's exterior size. The trunklid hinges don't intrude into the cargo area, and liftover is low. However, a small opening limits the size of items that can be loaded. Small-item storage is limited to a smallish center console and less-than-generous glove box." -- Consumer Guide
