My buddies has a cts and there is not much room for his and his buddies golf clubs. The reaer seats in the cts really dont have too much legroom. He is trading in his cts for the new STS when it comes out.



His CTS has a ton of power and is a younger mans car.

They are almost 100% different cars.

Use search and look at specs, pictures, etc. The STS is a full size car, the CTS is a mid size at best.



STS is near the top of the line for Cadillac, CTS is near the bottom.

Hi!

The Cadillac STS is actually a Seville produced in the early 90's. The small CTS, produced after the turn of the century, is one of two sedans Cadillac puts out. The other sedan is the DeVille, which is bigger.

2005 Cadillac STS Test Drive

When did Cadillac enter the best bang-for-your-buck category? And how did they win? Can you believe I'm talking about Cadillac? Well I think the 2005 Cadillac STS with a 3.6L V-6 is a strong contender for bargain-priced luxury car of the year. Base price is close to $10k less than base on the 4.6L V-8 version. Best of all, without looking under the hood only the keenest eye can pick out the difference between the two. MSRP: $41,220; Warranty: 3 years/36,000 miles.

First Glance

The completely re-designed and re-engineered rear wheel drive Cadillac STS was introduced as a 2005 model. It has a very smooth, almost streamlined shape; it's much rounder than the edgy CTS with which it shares chassis components. As a huge fan of the CTS, I found the STS's egg shape somewhat off-putting at first. However, after spending just a few hours with it, I had completely changed my mind.



Frankly, what first prompted me to re-think my opposition was the reasonable base price of the V-6 equipped model. Now I like a V-8 as much as the next fool but I don't like it when it prices a model I might otherwise like completely out of my financial ballpark. With the V-6, I get almost everything - no, everything - I'd want on my own STS without the extravagantly high price, which admittedly includes a lot of neat gadgetry. However, most of this stuff is, totally unnecessary on a driver's automobile like this.



The STS is available with both V-8 and V-6 engines. Starting in the 2006 model year, AWD, which is currently only available with the V-8 can be ordered with the V-6 as well. However, with good tires and traction control, you don't really need it. Personally, I wouldn't bother.

In the Driver's Seat

Both the driver's seat and the driving position are first rate. The steering wheel includes tilt as well as a telescopic feature. The interior trim is understated and businesslike - very stylish in a contemporary, European way. The standard leather-wrapped steering wheel with sound controls and the aluminum console trim are perfect. The optional eucalyptus trim would be too much.



While very much in keeping with the current styling idiom, the high sill and high dash will take a bit of getting used to for people who haven't bought a new car in a while. I found it a bit claustrophobic at first, although after a few hours behind the wheel I'd gotten used to it.



The STS is a big car. Not big like the your uncle's old Coupe de Ville, but still pretty big. Which makes it all the more difficult to understand why there's so little space for rear seat passengers' legs. I won't get into interior volume measurements, which frankly can confuse as often as clarify, but I'd bet there's less room back there than in the new Hyundai Sonata - a car with a much smaller footprint. With the square cut rear door, however, entering and exiting was a breeze.

On the Road

The STS is built on what GM calls the Sigma platform, which also underpins the considerably less expensive Cadillac CTS. The STS's ride is quite a bit firmer than Cadillac's traditional buyer is used to. However, this provides much more information available about what's going on where the rubber meets the road. Which, no matter how you slice it, is a good thing.



The new Canadian-built 3.6L V-6 engine is a delight and not just because it's nearly ten grand cheaper than the Northstar V-8 on which it's based. The V-6 puts out 255hp and 252 lb-ft of torque (90% of which comes on at 1,600rpm). Step on the gas and you go girl! All this power gets to the wheels via a 5-speed automatic transmission. This combo will serve perfectly well in 99% of the driving situations most of us are likely to find ourselves in. But folks who live in or near mountains might occasionally find themselves wishing for a 6th gear to get them up those long, momentum-sapping grinds.



With the bargain price of the base V-6 STS, you forsake niceties like the magnetic ride control suspension, adaptive cruise control and heads up display. But know what? You don't need any of that stuff. And frankly, you won't even miss them.

Journey's End

I really like the STS with the V-6. I find the idea of a reasonably-price, full size Caddy with state-of-the-art engineering, handling and build quality tremendously appealing. I'd even go so far as to say the STS V-6 offers as much dollar-value as almost anything currently available in the American marketplace. I also think it offers far greater bang for the buck than the V-8 version. The V-6 will pull the STS from 0 - 60mph in 6.6 seconds while the V-8 is a car length quicker at 5.8 seconds. Is that 0.8 second worth 10K to you, Bucky?



My major concern with the V-6 engine is its fuel economy. You'd think that with two fewer cylinders and a lot fewer horses, you'll go further on a tank full of gasoline. On paper, you do. However, in real life driving situations, the V-6 doesn't get any better fuel economy than the V-8.



Yet, I'd still take it over the V-8 simply because the V-6 package offers such terrific bang for the buck. So if you're considering something in this class from Germany or Japan, do yourself a favor and check out the STS V-6. You won't be giving up anything in the way of engineering and build quality, and you'll be keeping more of your money at home.

The STS is a bigger car (an old fart's car). I liked driving the CTS especially with 3.6 liters.

I've owned both cars. My STS was problem free until 100k when I traded it in because I bought a house on a hill and had to think about the winters. Not a single interior creak even with 100k on it.



I traded it in for a newer CTS, which had a much nicer designed interior, however the quality is crap. I have driven dozens of CTSs, old and new and once they get driven a little bit (within the first 20k miles), their interiors are louder than a 1987 Yugo GV, and it's not even close. The reliability of the CTS is also pretty terrible, where the STS was rated pretty good and my experiences confirm...



I would never buy another GM car after the CTS, and I would not suggest one to a friend either.

Both are midsize luxury cars. But let me you a difference between the two. The CTS (produced since 2001) is designed to take on performance-oriented competitors: e.g. Acura TL, Lexus ES, Audi A6, BMW 5-Series, M-B E-Class (the Infiniti G is a compact) The STS (2004-2011) is more for comfort: e.g. Acura RL, Lexus GS, Infiniti M, GM's own Buick Lucerne; the Mercury Grand Marquis The CTS is designed to attract young consumers. The STS is more upscale and therefore appeals to the older (i.e. >35 y/o) consumers.

CTS is Coupe...meaning it's a 2 door model...while the STS means sedan or 4 door.
