Welp, I'm old school and have this irrational fear of turbos. There may be a bunch of AARP eligible people like me shopping Buicks who would prefer a V6.
 
I don't rent all that often but this is the first Buick I can remember ever having (the rental places were sold out so I wound up renting from a Buick dealer on that trip).
 
There was a lot to like about the Buick. Comfy for the two of us, lots of gadgets to play with and I liked the way it drove, although it did have a bad pull to the right that I attributed to the tires or a curb hit by the last driver. The back up sensor saved the bumper when I was parking it in Chicago.
 
Old, old drivers? My 87 year old mom recently gave up her keys - she drove a 1990 Mazda Protege off the lot new into the twilight, after driving Buicks all during her 30's and 40's. But my elderly mom-in-law swapped her BMW for a Buick 5 years ago.
 
Sorry, I'm rambling here. I've never spent any time in a Camry or Accord to really compare, and spend most of my drive time is in a wagon or minivan. The last sedan I rented was a base '07 Mustang and the Buick was light years ahead of it for what I needed.

Well, from my recent experience in a Mustang, I would say that just about anything on the road would be light years ahead of it. I do find it telling that coming out of a minivan, you liked the way the Lacrosse drove. In terms of my personal preferences, even in a large car for highway cruising I would prefer it not drive similar to a minivan.
 
But I think a large Buick with a direct injected, 2.0L turbo four could end up rated somewhere around 25/35 EPA and still have plenty of power for everything people need their large cars to do. And that would be a huge step forward in terms of fuel economy for Buick.

The basic facts of life are that the turbo 4 in the Sky/Solstice does not get over 30 MPG, so a turbo 4 in the Lucerne probably would not either. However, with a hybrid turbo 4, 35 is possible. The Lacrosse on the eps II platform might get better economy with a turbo 4 if, and only if it is designed for the 4. That means designing the Lacrosse eps II to be much lighter weight, using carbon fiber perhaps. But with a carbon fiber body, the Volt system would make more sense.

Yes, but what you forget is that the turbo in the Solstice is a low-tech, high-hp engine. I would be looking for the Buick turbo to have DI (which allows them to raise the compression ratio and thereby lower the boost, so that the engine can run with very little boost in steady state highway cruising - imagine how much gas a 2L naturally aspirated engine uses running at 70 mph, and think of how high that highway mileage could go) and also to make less power than the Solstice engine - the current Buicks only make like 220, so it would be OK if the proposed turbo 4 made about that much power too, I would think.

Buick's dilemma by grbeck

My parents just replaced their 1999 Park Avenue with a 2008 Lucerne CXL. Their Park Avenue was beginning to nickel-and-dime them with repairs. It had 158,000 miles on the odometer. They were obviously satisfied with Buick, as they bought another one.
 
The Lucerne is certainly a nice car, but represents Buick's dilemma. It satisfies loyal customers - my parents are Exhibit A in that regard - but I don't see anything that will attract buyers from other brands. It's a nice, comfortable car...but there are lots of nice, comfortable cars on the market that don't carry the baggage of the Buick nameplate.
 
As for the Enclave - it's a very attractive vehicle (much better looking than the Honda Pilot and Acura MDX, for example), but it debuts just as the market for big, heavy vehicles like this is evaporating. It's about three years too late.

A loaded Buick Lucerne CXS V-8 was second on my car shopping A-list and probably would've been a more sensible purchase than the Cadillac DTS Performance I ultimately bought.

The Solstice/Sky turbo is already DI, but it is old-school in that it's optimized for horsepower at the expense of fuel economy and NVH. A mild-boost DI 2.4 turbo coming in at 215hp or so would be a better fit for the next Lacrosse, and the Lucerne could do well with a mild-boost 3.0 V6 in place of the current 3.6 and 4.6.

I certainly agree with you. I have no idea where nippononly is coming from with that remark?????? 28mpg certainly sounds very reasonable to me. And the comfort level alone betwenn that and an ECHO is huge!!!

I guess to me, what matters the most is the context in which this 28 mpg is taken. For instance, if I get out on the highway in my Intrepid and average 70-75 mph with the a/c going, I'd probably get about 28 mpg as well. If I turn off the a/c and loaf it, more like 60-65, I've managed to get 31-32 mpg. Driving my uncle's '03 Corolla in a similar gentle manner got me 37.4 mpg. So the real test, to me at least, is what kind of economy that LaCrosse would get with ME driving it.
 
Now if we could get Nippon into a LaCrosse and see what kind of economy he gets out of it, to compare with his Echo, or the 4-cyl Accord and Camry he mentioned, or get Steve in a 4-cyl Accord/Camry and drive it similar to how he drove the LaCrosse, it might put the numbers more into perspective.
 
For instance, if I'm only getting 37.4 mpg out of my uncle's Corolla, I doubt if I'd be able to get mid to upper 30's out of a 4-cyl Accord/Camry, unless I really drove it like an old lady.
 
Now depending on how you drive, you might be able to get a LaCrosse to break 30 mpg. Supposedly it's not that hard to do with older 3.8's, like the Regal, LeSabre, and Impala. I think Lemko's even been able to get close to 30 with his '88 Park Ave. The 3.8 in his car isn't as sophisticated as the newer ones, but the car's not as heavy either, so those aspects might cancel each other out.

Once again, let me make it clear I was not comparing the Echo. Nothing Buick will make in the next 20 years will come close to the fuel economy I can get out of that Echo, which I bought to be my commute car.
 
I was comparing 2 long highway rides I did in the last 18 months, one in an '06 Camry, and one in an '04 Accord. They both pulled about 37 mpg overall. A/C running constantly, one was with 4 adults, the other was with 3 adults and 2 small children, both running 70-75 mph most of the time. Oh, and for andre's benefit I will add that I was the driver in both cases.
 
bumpy: I wasn't aware the Solstice turbo already had DI, but it makes sense. I agree with you that a low-boost DI 2.4 turbo makes good sense as the base engine for all future Buick sedans. Better city numbers, really good highway numbers, without a noticeable loss of the power Buick owners expect to have.
