Buick Lucerne and DTS....same architecture?
I was having an argument with a good friend tonight. The DTS is slightly bigger, but they share the same wheelbase, and several interior/mechanical bits...plus they are built at the same plant. I say they are closly related....but he says they are about as related as a 4th Gen Camaro and Monte Carlo...which share a steering wheel. I am just wondering who is closer to right.
Also...when the friend reads this...I just wanna remind you...you are the one who would not let it die

Re: Buick Lucerne and DTS....same architecture?
Uhmmm........no, I did NOT say that they were as related as the Camaro and Monte Carlo.
YOU were the one that said "But they have the same steering wheel!" And I said .....so what.......so did the 2000-2002 Camaro steering wheels (the leather wrapped one) and the Monte Carlo!
The Chevrolet Caprice was built for a while at the Clark Avenue Cadillac Plant in the late 80s along side the Fleetwood brougham. I would not say they were the same car.
Yes......they share HVAC.....cooling systems (when equipped with Northstar)...but check the dimensions of the body.....ain't the same car!

Re: Buick Lucerne and DTS....same architecture?
My asertation is that the DTS is based on the same updated G Platform (is that the name of the Aurora, Bonneville, LeSabre architecture) as the new Lucerne. My evidence is that they have the exact same wheelbase, are made at the same plant, and have very similar interiors (below). Also consider how both products were redone (Lucerne is a refreashed LaSabre) and released at almost the exact same time. The DTS is however longer, taller, wider by a few inches and heavier....but because they share the wheelbase, I think it is simply the same G architecture just Supersized and loaded with Caddy extras. I think Scott is saying it is a completely different architecture. He kept pointing out the Lucerne had the same radio and HVAC controls as the Impala, but they are not the same platform.

Re: Buick Lucerne and DTS....same architecture?
They're the same G platform IIRC, but obviously very different cars. FWIW, I just went to the Western MA auto show on Saturday night...both the Lucerne and DTS are great cars. I like the DTS way more than I thought I would, based on the dowdy DeVille it repalced. The interior is gorgeous, and those seats are incredible!
They had a black Lucerne CXS with chrome 18s...wow. Wide tires on a Buick (245s)...loved it
My girlfriend loved it too, and she's 22!

Re: Buick Lucerne and DTS....same architecture?
They are the same in the way a LaCrosse and Grand Prix are the same. Basic structure is much alike, yet outside of that, most elements are not shared. Obvious items such as HVAC and radio are shared, but all body panels, interior trim, wheels, etc are specific to each model.

Re: Buick Lucerne and DTS....same architecture?
well, according to wikipedia, they are different platforms.. the Lucerne is on the G platform, the DTS is on the K platform.. but one article says they are the same platform with a different name
http://en.wikipedia.org/wiki/Buick_Lucerne
http://en.wikipedia.org/wiki/GM_G_platform_%28FWD%29
http://en.wikipedia.org/wiki/GM_K_platform_%28FWD%29
http://en.wikipedia.org/wiki/Buick_Lucerne
Although the rear wheel drive GM Zeta platform was considered, the production Lucerne introduced at the Chicago Auto Show on February 9, 2005, is a front wheel drive derivative of the G-body Buick LeSabre
With the demise of the Bonneville, Park Avenue, and LeSabre after 2005, the only remaining G-body car will be the Buick Lucerne. This vehicle again shares a platform which is similar to the K-body. The K-body cars were replaced by a single ongoing model, the Cadillac DTS.
Unlike most GM platforms, the K was not shared by multiple divisions (though the E was). Technically, though, the architecture was shared under a different name: the GM G platform was based on the K and produced at the same time.
The Seville was replaced with the rear wheel drive Sigma-based Cadillac STS for 2005, but the Deville's replacement, the DTS continues on the K-body.

Not saying you are wrong but really what constitutes a different platform code?

I understand where you're coming from with the body codes, but......
Why would the STS and CTS have the same body code then? Granted, they are both based on Sigma architecture but are very much not the same car. Why's this?

Re: Buick Lucerne and DTS....same architecture?
I know the Lucerne shares its platform with the long since extinct Olds Aurora... and I've also heard it shares its platform with the DTS - I've heard that time and time again.

Re: Buick Lucerne and DTS....same architecture?
The question being raised here is how different is the "K" from the "H". Not so much on the letter designation itself.
It has been suggested that it is only a small difference, and shares much of the same thing.
