There is a conventional RWD engine, a sidewinder FWD engine, and a RWD supercharged engine. In years gone by there were two horsepower variations.

Variations of the Northstar have been developed for racing, most notably the twin turbo L47 used in the Northstar LMP LeMans car.
GM also has a production-ready V12 Northstar that was never released due to upcoming changes in CAFE regulations (rumored to have been slated for the Escalade and ULS sedan).

Originally, "Northstar" was used to describe not only the engine but the whole system which included anti-lock brakes, adaptive suspensions, a liquid-cooled alternator, and antilock brakes (when many of those became commonplace in vehicles, the term was used to describe just the engine, the design of which still remains fairly unique).

I thought this thread was going to be about the Mosler TwinStar Eldorado.

I assume you are talking about the differences between the old SLS/DHS and STS/DTS Northstars. Not all american auto buyers wanted a high-revving european style engine, so the base and luxury versions of the cars came with a Northstar designed to feel effortless around town with higher torque and less emphasis on overall performance. Those who wanted a performance sedan were treated with the slightly higher horsepower and better performing "T" acronym cars.

There were two versions of the engine to fit differing preferences (european-sport versus american-luxury).

Wow.

Interesting concept, but honestly kind of disappointing performance numbers considering all the work that has been done.

...and moving the rear wheels further back really messes with the classic Eldo design. :/

Not really sure how I feel about this one.

The car went through so many electronic tweaks that every magazine that tested it achieved wildly disparate numbers. The best I ever saw was a 4.3 0-60, which for the time was incredible.

From a cosmetic standpoint I don't like the rear wheels pushed back, but I give Mosler a Gold Star just for the "wow" factor of building a twin engine Cadillac.

Thanks,this explanation answers my question,I just wondered why cadillac
would make two engines that are so close in design and performance.
I wasn't out to critize their motives.

This is just a Chinese copy of the Hurst "Hairy Olds" cars.

Consider how many versions of the Small Block Chevy were made many years. 8,9,10? Some 5 or 10 hp apart.
