2006 Cadillac STS-V -- High on Power...and Curb Weight

I just got a drive in the 2006 Cadillac STS-V and I was left with two overwhelming impressions. It's really fast, and it's really fat! I know that second trait doesn't particularly mesh with the image of a high-performance sport sedan playing in the BMW M5's segment, and that's probably why I wouldn't suggest cross-shopping these models. The STS-V has more interior space than the M5, and its ride quality and interior design make it feel more luxurious overall (though the interior materials still don't line up with BMW's...)...

And yes, it moves out with authority when you floor it. But that same sense of athleticism disappears when going around corners. There's too much body roll and the car just feels too BIG to actually claim "sport sedan" status (even parking the car was more of a challenge than I expected). I guess you could argue that its dimensions (both inside and out) and driving demeanor make it closer to a 7 Series competitor than an M5 competitor, which then makes the $75,000 price tag seem like a bargain. But if you're thinking luxury and performance, and your definition of performance involves more than going in a straight line, spend that $75K elsewhere.

Sounds like Cadillac couldn't quite give in all the way to the pure Euro-handling, and the accompanying firmer ride. Might turn off those Fleetwood owners on the fence deciding between this and a Lexus...

I'm coming back to LA for another business meeting. I have tomorrow afternoon and evening free, to drive around the canyons and pretend I'm an Edmunds editor in a sports car. I hope I get something sportier than a Tauraus this time. Anyone care to give me a ride in your long term Miata???
 
I almost rented a Boxster from an exotic rentals place near LAX, but just couldn't justify the cost this time. Maybe next time my wife can tag along and she'll let me do that as long as she gets a turn to drive.

The one thing I never understood is this constant bashing of the interior materials used in the STS. I looked at every player in this segment and the STS was best in interior room and comfort, middle ground for materials. The BMW 3 and 5 series are the absolute bottom for interior luxury and materials. When test driving a new 2006 5 series, I honestly thought it had vinly seats and I asked the sales person if this was so. Needless to say, he was highly insulted. But the off-white leather in my test drive car was poor, crinkled and thin. The dashboard was plain as white bread. And the interior was too cramped for this much money. But objectivity is hard to find in auto editors, particularly when comparing to American cars.

The STS-V is more like the CLS63 and E63 AMG, both are heavy as well, but damn fast in a straight line. I remember a few months back the STS-V finished second out of 3 cars in a C&D or MT comparo. The M5 finished first, and the CLS55 last.
 
Karl what are your thoughts on the new Audi S6? Is it good enough for the M5? Based on what I've read, I expect it will be fast but too heavy, like the STS-V.
 
Still the STS-V is a pretty good bargain for what you get. 469hp and a loaded car for $75,000? Not bad.
 
Guess that puts the M5 in a class of its own....................

Baltoman, I know what you mean. I actually find the constant bashing on automotive journalist objectivity pretty tiring, especially when it comes from people who likely have their own biases PLUS don't have nearly the level/quality of exposure to vehicles that automotive journalists have.

I haven't been near the new S6 yet, but it will probably be relatively heavy simply because of the AWD system. However, the RS4 is no lightweight, and it ROCKS! Curb weight is only one aspect to a vehicle's handling. Suspension design and tuning is another huge element, and Audi is pretty good at making their cars "drive smaller" then their curb weight suggests. Chrysler is good at it too...at least when Mercedes is helping. The 300 SRT8 is way too big/heavy to truly handle well -- but it does!

You dont need to be an automotive journalist to determine whether or not a car has quality materials. I think that is the problem with many auto writers, they give themselves too much credit. I have been in most brands of luxury cars at auto shows and events and the STS interior is fine. It may not be up to Audi standards, but it can hold it's own against most anything else, especially MB interiors. The interior of the C and E class benzes is more plasticky and non luxurious than any STS, especially the STSV which has the leather dashboard. I got to compare the STS and 530 interiors at a driving event and the % series interior was dark, depressing and full of hard surfaces that did anything but scream "luxury".
 
THe STS-V doesnt have razor sharp handling because Cadillac chose to give it a compliant ride. The M5 is sharper, but probably not as good as a daily driver. The STS-V is in the same weight class as the M5 and E63 so I dont see the point in complaining about its curb weight. The S6 has less more and weighs more than the STS-V but I bet we wont read any critcism of that car. I'm also trying to figure out why the $50K CTS-V wasnt mentioned as a competitor to the RS4 you guys just tested. Why pay $20k more for the same performance capabilities?In terms of weight and body style, the CTS-V is more of a direct competitor for the RS4 than the M3 will be.

That's the great thing about 1487 -- he's always there, waiting at the ready, to prove my point about reader biases.

Just to clarify, are you saying anyone who doesn't agree with you is biased? Thats very interesting but it doesnt address any of the points I made. While the '07 E class interior may be improved, the old one was just average for this class, in fact you didnt even get wood on the steering wheel. The pre-2006 C class was extremely average considering its price.
 
BTW, when I was at that event comparing the 5 series and STS most people I observed were less than impressed with the 530 and many were surprised how much they liked the STS. But, then again they were probably all biased.
 
For the record, I do like most of BMWs lineup as long as I'm not thinking about the horrific rear end styling. My opinion of BMW is MUCH higher than your opinion of Cadillac so I'm not making these points to suggest the M5, or any other BMW, isnt a great car. I'm just saying the STSv isnt as bad as you say. My coworker just drove one in Vegas and said it was a blast, although not as fun as the much lighter Vette.

Karl never responds to vaild points. I agree and was not impressed with the materials/design of the 530i and found it in no way shape or form superior to the STS. The shape and fake oragami theme is simply overdone as is the exterior. Actually, the 5 and 7 don't look bad at all with the exception of the rear. I'll take the old 5 series over the new one any day. I saw the STS-V with the Tango Red interior and leather dash/console and was very impressed.
 
First off, every luxury car with a hyped up engine is not supposed to take on the M5. None of them offer manual transmissions and that my dear editor is the main difference. No one is arguing that BMW doesn't make the best DRIVING machines. They have a narrow focus and they exceed at their goal. However, rich people who want fast cars don't always want to be jerked around by SMG or punished by a stiff ride. If I could afford one of these cars, I'd want the best ride possible to cope with these rough streets we have in Philly.
