Just so we're all on the same page, the terms are "Longitudinally Mounted" or"Transversely Mounted"

The Bonneville, model years 1987-2005, along with all other H, C, W, A, U, V and related GM FWD platforms, are the latter of the two.

I worked on a SAAB that was FWD and the engine was longitudinally mounted. The engine sat backwards, so that the belts were in the back, next to the firewall. I had to change the belts.
Strange little car, but seemed to be well built and it ran pretty good.
Some of the Audis were AWD in 1993.

If you want REALLY WEIRD, one of the French car companies made a car with a transversly mounted engine in the rear. It was Front-Wheel Drive.....

i recall a thread of someone finding a "rare", burgandy awd, and cought some parking lot pics. i swore it was a bonne. ehh must have been the 6000, as john said. idk?

One of the main reasons I joined this site was to clear up the confusion I saw on several threads about AWD Pontiac sightings. There was no Bonneville AWD. It would be the 6000, available in the STE trim in '88 (124 made) and '89 (1,376), and in the SE trim in '90 (unknown number; records weren't separated from total SEs produced). The '89 & '90 looked identical from the outside, save for the badges, and were only available in dark sapphire blue, and dark garnet red, both colors available on the SSEs from those years. They also had the SSE style seats, spoiler, and trunk keyhole cover. They don't say 6000 anywhere on the outside of the car. Just STE in big letters like the SSE, and in the bar underneath where Bonneville would go, it says All Wheel Drive. Between all this, people were mistakenly thinking that maybe it'* a rare edition Bonneville, especially with no markings to indicate what kind of car it was. Here'* some shots of my remaining AWD STE, though it'* up to 98k miles, and it doesn't look quite this nice anymore...
