Series III 3.8 liter Engine
I noticed the new 2005 Buick LaCrosse is sporting the Series III engine. Is this the first year (2005) GM has introduced this engine. I wonder what the specifications are and how much "different" it compares to the Series II engine.
Any input?? |

The Series III 3800 actually debuted last year in the 2004 Grand Prix GT. The power output of the Series III is identical to that of the Series II. To my knowledge the Series III is nearly identical to the Series II. The only two major changes include a new aluminum upper intake and electronic throttle control.

The CX & CXL have the 3800 Series III but the CXS has the new 3.6L VVT DOHC V6. No more blower. The torque figure is way down compared to a Supercharged 3800 Series II. Regardless of any improvements, the horsepower for the Series III remains the same as the Series II. |

I was pricing the LaCrosse today, and I noticed the same thing. Why would the CXS have a smaller engine than the base CX's and the CXL's (thats the one I was pricing) 3.8L? I am assuming the "S" stands for "sport" (where the "L" stands for "luxury"). Makes no sense to me.

I'm going to keep an eye on it and see about any first years bugs before taking the plunge. The 3800 Series II was very reliable. |

I believe that Buick really blew this one on the CXS. The 3.6 leaves a lot to be desired. However, the logical thing for Buick to do is replace the 3.6 with what they already have in production from other products such as the '05 Grand Prix GTP. It has a supercharged version of Series III 3800 putting out 260 hp and 280 ft-lbs of torque. I'm going to sit this one out until they get the mess straightened up, however, the Pontiac is looking awfully good at this time. |

I test drove the CXS today and I didn't notice the tranny problem. But then again, I wasn't looking for them. The ride was good and the sound deadining was good. But I guess if I test drive the CXL, I will try to notice the difference in the tranny.

Re: Series III 3.8 liter Engine
Give it 60K miles, it's a caddy engine, dont expect it to be reliable. I'd take the 3800 intake leaks over the caddy piston ring problems any day. As for tranny problems, we've already had one LaCrosse come in the shop with intermittent shifty problems, had a rolled seal on the number 2 or 3 clutch i believe.
As for the car overall, i'm very impressed with it. |
