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.

28 isn't that hot when my dad gets 31 or so in mixed driving with the Avalon.

Nippon:
 
What I think you are missing is that the Big Buicks not only have a bigger engine, but weigh more. Your Camcords weigh on average, 3150 lbs w/ the 4 cyl engines. My '99 Ultra weighs a shade under 3900 lbs. Whenever I have taken it on long trips, there are 4 people (2 large adults and a teen and a preteen) plus 4 pieces of luggage, I get between 30-33 mpg, depending on how fast I go (60-65 will get me 33, while 70-75 gets me 30). You also don't mention whether they were sticks or autos, as that can make a difference too.
 
My Uncle averaged 29 mpg in his '97 Ultra in all the trips he took from RI to Fla. doing 75-80.
 
So, you see, the mpg numbers aren't all that different when you consider the extra 750 lbs you carry around.
 
Think of it this way: You got ONLY 20% better fuel economy in the Camcords in cars that are 25% lighter, with engines that are 35% smaller than I did.

How funny that this one little remark made to steve, half tongue in cheek, has generated such enthusiastic interest from folks that own Buicks!
 
Let's see, to address some of your points:
1. both the Accord and Camry seated four adults comfortably, size was not a limiting factor
2. both of them were automatics (boo hiss )
3. if I am making the correct inference, you somehow view 750 extra pounds of curb weight as a positive. I view them as a needless negative, and certainly I WOULD agree with your implication that one significant reason the Buicks do a lot worse for gas mileage is the excess weight.
 
Really, all I was doing was calling steve out a little on his remark, and certainly if he is coming out of a minivan (which I didn't realize when I made the remark), 28 mpg must have seemed glorious. I don't in any way feel that Buicks have notably worse fuel economy than other large cars, but rather that the whole breed (large cars, that is) is needlessly gas-guzzling.
 
Stuff a little technology under those hoods, boost fuel economy and improve driveability all in one fell swoop, where's the harm in that in what is supposed to be a "premium" or "near-lux" automobile?
