I do see your point and agree but that is not the way the industry works today. Perhaps they should have waited one month and called it an '07 like the new GM SUV's? If a car is held until the first of the year they can call it the next model year.
Too bad Buick thinks it has to pander to the faddish low profile tire crowd, isn't it? There is certainly nothing wrong with 16 or 17 inch (at the most) tires.
I tested out the HK system in a number of other cars before it was spec'd for the Buicks. It really is amazing. their Engineering facility is top notch.
With a CD (happened to be country music -- not even my taste), the sound was truly excellent. The music was a nice complement to the Martha Stewart "inspired" sandwiches and wine they served last night.
The sales guy couldn't believe I spent so much time with the stereo. He'll be really astonished when I bring my own CDs in before making the final purchase.
Acceleration with the V8 was nice but not thrilling. I didn't get to redline though. Ride was smooth and quiet. I doubt the low-profile tires will be a problem.
Other observations...
Lumbar control was broken on the driver seat of the demo car. Doesn't bode well for overall quality. I also wish the interior looked richer. It's not offensive but no more impressive than a family car. The plastics feel cheap. Lack of telescope steering wheel is an odd oversight too, especially after Consumer Reports criticizes the Avalon on only this one item.
But I stated the same disappointment as you about the lack of power in both engines that power the Lucerne. The competition has better V6 engines, 5-speed autos and some even match the V8 power with a V6.
If GM really means to make Buick the rival of Lexus, they need to work much harder than this.

If the Lucerne has a performance issue, the problem appears to be the transmission. Only 4 forward gears as many have noted. And gear 4 is an overdrive for gas mileage, it has nothing to do acceleration. The horsepower (actually torque) is there, it's just a matter of getting it to the ground. A 5 or 6 speed is critical in this heavy sedan, and much of the competition has one.
Beyond that, the car sounds like a winner at this point....
So, yes, the Lucerne V6 is underpowered, even if the same engine was adequate in the Le Sabre and then.
Thanks.
I'd still love to see Buick grab the 3.6L engine and/or 5 spd from the modern STS. But I'm guessing they're trying to save a buck by using slightly older designs, which would be OK if performance didn't suffer.
The 5 speed automatic trans in the current 'modern' STS is a RWD only trans. 5L40 & 5L50. Will not help the Lucerne.

Still very surprised to see the max. TQ limit GM has published for their new 6 speed FWD trans. -
6T70:
“Rated for engines up to 315 horsepower and 280 lb.-ft. of torque”
However, they could develope a 6T80 version for higher performance models too...
Given that the Lucerne uses the 3.11 there is no choice but to add gears for acceleration. A 5 speed would do wonders..... yes...
Indeed. I've read many people complaining about it in the 500 and Fusion forums.
Thanks.
The SLS performance on 0-60 was rated at about 7.5 seconds, while the STS was rated a bit faster, about 7 seconds I think. The base northstar has more low end torque than the STS's high performance northstar.
The Cad in the other post was an STS with the 3.71 gears, hence the faster acceleration. There is a world of difference in a 0.6 final drive change in any car, as you mentioned.
2014 Malibu 2LT, 2015 Cruze 2LT,
Lucerne is 3.11 reduced by the overdrive gear IV as I read the information.

What I could find in my back issue collection last night suggests that the FWD STS was a 6.8 sec. 0 – 60 sedan.
R&T, Feb 1998 issue P 76 & 77:
0 – 60: 6.8 \ 4050 #
Final drive: 3.71 to 1
C+D, Nov 1998:
0 – 60: 6.8
MT, Aug 1999:
0 – 60: 6.8
I do not recall ever seeing a published 0 – 60 time for these cars below 6.0 sec.
The EPA ratings at the time were: 17 / 26.
What is your source for a sub-6 second 0 – 60?
My current sedan has been tested at 5.7 seconds for 0 – 60 by C+D.
- Ray
Intimately familiar with how much difference in feel there is between a high 6 second and a high 5 second 0 – 60 sedan . .
The original C+D test (1SG w/3.42 to 1 final drive) reported 0 – 60: 6.0 and 14.6 at 97 in the Quarter.
The later C+D sedan comparison with a 1SE version of the STS (and 2.73 final drive) reported 0 – 60: 6.0 and 14.5 at 100 in the quarter.
And the 30 – 50 and 50 – 70 mph times were actually better for the 1SE than in their previous test of the 1SG.
Given Michelin Energy tires (not exactly designed for maximum dry grip) in size 235 / 50 x 17 on the tested 1SE vs Michelin Pilot HX MXM4 in size P255/45ZR-18 on the 1SG, I don’t expect that the 1SE would have better launch traction . . .
Granted the 1SF test weight is quoted at approx. 150 pounds lighter (attributable to less extensive equipment, I expect)
The braking performance for that 1SE was worse than the 1SG's . . 70 – 0 = 190 feet vs 177 in previous 1SG test. Exactly as I’d expect, given smaller tires and less bias toward ultimate traction in the tread compound and design.
In at least a token attempt to bring this into a Lucerne context (and I actually believe it is relevant on this board) since there is no longer a FWD Seville (STS or SLS), and no Olds available at all (FWD or not), it seems to fall to the Lucerne to attempt to win sales for GM where people do want and appreciate the positive attributes of a medium sized FWD sedan. Things like a substantially smaller front & rear ‘hump’ than the STS . . .
And the Lucerne acceleration in 6 cylinder form appears clearly less than stellar – and in V8 form, well it again appears to be somewhat less than many expect.
I have driven both a 1SE and a 1SF (3.23 final drive) RWD 2005 STS. I would personally consider the 1SF level of acceleration acceptable in a $35 – 38K mid-sized sedan. But not what I perceived in the 1SE. Fugedabout the V6 in either the STS or the Lucerne (for me – Torque snob) regarding acceleration.
So – the question (one important question) becomes: Will it sell anyway?
We shall see . . .
As someone pointed out above, GM may release a higher capacity 6 speed automatic for FWD eventually – if they do, it could be an aid in the cause. Allowing a better compromise between acceleration and high MPG \ low NVH at highway cruising speeds.
Again – we’ll see.
- Ray
Wondering also if 2007 will see something like a Buick Lucerne GXP – or GS???
"Lucerne Acceleration Performance:
The original C+D test (1SG w/3.42 to 1 final drive) reported 0 – 60: 6.0 and 14.6 at 97 in the Quarter.

But you are talking about the STS, right? Which one/year? The older FWD one? I apologize if Im the only one who finds your post confusing, but I enjoy this discussion (generally as an observer) and am totally missing your point.
~alpha
Sorry - Referring to the newer \ current STS here. RWD.
Relevant to this discussion (I think) because of the context and (apparent) role of the new Lucerne as "top of the GM line of FWD". Used to be the Caddy STS & SLS.
- Ray
Always willing to be proven wrong . .
Oops - your post reminds me that there is a 'step up' FWD at GM. The DTS.
For several reasons, I'd never consider it, but starting at $42K, it is "above" the Lucerne.
One reason I follow this thread is that now (again, with Olds gone, and the Pontiac Bonne gone, and the STS \ SLS Caddy FWDs gone) this is the overall size I'd likely prefer when I trade my GP GXP.
If a performance variant of the Lucerne, with more HP and more TQ (from this or some other V8) and a 6 speed automatic with manumatic \ paddle shift, a more performance oriented suspension, wheels & tires, etc. becomes available – I would at least look at it.
- Ray
Not likely in the market again until sometime next year . .
Although I have no access to a true Autobahn (sadly) I am curious about what you’re getting at here.
My personal preference is low RPM at cruising speeds. My current Sedan shows approx. 1700 \ 2000 and 2250 RPM at 60 \ 70 and 80 MPH. And that gearing (2.93 to 1 final drive and low profile 18” tires) would likely translate into approx. 2800 RPM at 100 MPH and 3350 RPM at 120.
Although I have never attempted cruising at those speeds, assuming that the wind & road NVH did not rise too quickly, my cruising at up to 80 suggests to me that sustained 100+ would not be a problem – if there was a venue allowing this safely & legally here in the South East US.
When VW introduced their 8 cylinder 250+ HP version of the Passat (W8), they changed the final drive from 3.0 to 1 (Europe – with opportunity to travel on ‘real’ Autobahns at higher speeds than is currently legal here) to 3.5 (US).
This (and other similar reading) leads me to believe that in a general sense, many Europeans generally prefer lower RPM cruising and US drivers prefer quicker acceleration. Thus, in this context, the 2.73 in your example would appear to be a more appealing option than 3.08 or 3.1.
What am I missing?

Hoping some day to actually drive a fun sedan on the Autobahn . . .
My source for 0-60 times of the older STS is my own test on a 110K mile 9-year old car using a G-Tech accelerometer. I know it's always better to compare 0-60s from the same source, i.e. the same magazine. So maybe my statement exaggerates the difference between the old STS and the new Lucerne. Still, I don't understand why the Lucerne can't have better acceleration or much better fuel economy. My STS gets 27 on long 70 MPH trips.
My opinion is that the car magazines complain too much about 4 speeds now that 5's are more common. A 4 can be made to work well. I'm so happy with my STS that my first choice would be to buy another one new if I could. By the way, the FWD STS is great in snow. I went to look at the Lucerne which seemed on paper mechanically very similar. But it hasn't completely won me over... yet.

I also think the optics of 197 hp just looks awful on a near luxury full size car.
GM advertises them but has NONE for sale. I waited a month for a dealer anywhere to get one. They never showed up. Can't see one now. So I bought an Avalon. Toyota has those in stock!
GM What a joke. They make a good car (so I have heard) they advertise the heck out of it and don't ship them.
Just like Chrysler and the New Yorker 25 years ago.
Won't american car makers ever, ever learn??.
I would love to buy american. But I can't buy what I can't see.
But what would you think about a $1500 increase in the base price for just the engine?
