Just a curiosirty question - Isn't the 3.6 in the Acadia a bored out version of the old GM 2.8 from the 80s? I remember that the 2.8 was increased to a 3.1 during the early 90s, and I think that is where the 3.6 came from. Or is the 3.6 just a brand new engine design.

I've also read recently that Caddilac is going to get a version of the lambda in two years, with a V8 option. :cheers:

Thanks!

That’s actually a big relief for me. The old 2.8 didn't have that great of a reliability track record. I had a '87 Beretta, loved the car, but the engine became crap.

You can read up on all of GM Powertrains products here:

The 3.4L (LNJ) would more likely be the successor to the 2.8L/3.1L motors. From the LNJ summary: RPO LNJ was developed on the solid foundation of GM’s highly successful 3100/3400 V6


The 3.6L (LY7) is a thoroughly modern DOHC 24-Valve engine.
