Doesn't the 3800 V-6 trace its ancestory back to the 401 cid V-8 Buick used in the 60's (or maybe earlier). I believe they made the first 3800 V-6 by chopping two cylinders off the V-8.
Incidently, I have a 1997 Riviera with a supercharged 3800. It provides plenty of useful power. What happened to the supercharger on the Lucerne?
My Riv's engine has leaked oil from EVERY possible oil seal, sometimes a second time after the first seal was replaced. I actually got my money's worth from an extended warranty replacing all those seals. A 1999 Park Avenue with the same engine and blower didn't have the problem. So I'm a little skeptical about the reliability of the engine.

And hopefully not a manifold gasket leak problem!

I've been doing a little research and it seems the 3800 V-6 was based on the 215 cid V-8 that originally appeared in the early 60's Special and Skylark compacts. For a history of the engine see Buick V6 engine

I recently asked more or less the same question and it seemed to open the gate, so stay tuned.

· Lucerne in March had its best-ever sales month both in retail and total sales; total sales were up 5 percent compared to February.
· More than 90 percent of Lucerne’s March sales were retail deliveries.
· According to Power Information Network data, Lucerne had the second-fastest days-to-turn in the upper mid-size car segment (28), trailing the days-to-turn segment leaders (Toyota Avalon and Solara) by only four days.
· Lucerne outsold a number of its primary competitors in March, including the Ford 500, Nissan Maxima and Volkswagen Passat.

does not rest with this car. They just put in the 3.6L DOHC VVT V6 in the Pontiac G6 for the 2007 model year (check out the G6 board) and I hope this means that in a MORE expensive car like this, they could do the same.
In base form, 250hp would do this car very well. It would be close to the 275, but then again torque is way more with the V8.
It would be nice to see the newer VVT V8 from the STS mounted for FWD use and put on the Lucerne, too.
The Base engine is the real problem though.

I am not sure what the G6 is getting for 2007, but the 2007 Aura (Saturn) is getting a 250 hp 250 lb-ft 3.6 for the upper end Aura. This engine would make a lot of sense for the Lucerne. The VVT northstar is a RWD engine and I don't know if it could be used as a FWD engine or not. I do know that the RWD northstar had a lot of changes made to the way the cooling system works compared to the FWD version of the northstar. So the two engines are different.
The LaCrosse 3.6, with 225 lb-ft of torque, is not that much different from the torque that the 3800 produces. The 3.6 does have more high speed performance, so even with 225 lb-ft, it could make some difference.
Just checked GM's 2007 guide and found that the G6 GTP does get the Saturn 3.6, not too surprising as the Aura is on the same platform. Buick's Lucerne will continue much the same for 2007.

Mostly color changes. No six speed automatic. A heated steering wheel is offered - standard with Luxury package on some versions.
