Released in the fall of 1989 for the 1990 model year, the U platform ([[General Motors GMT platform#MPVs|'''GMT199''']]) utilized a galvanized steel space frame underneath composite plastic dent resistant panels similar to those used in [[Saturn Corporation|Saturn]] models and the [[Pontiac Fiero]]. The vans feature unconventional styling, which some commenters likened it to a [[Black & Decker DustBuster|DustBuster]] vacuum cleaner.<ref>{{cite web |url=https://www.nytimes.com/1996/12/01/automobiles/after-the-dustbuster-a-clean-sweep.html |title=After the Dustbuster, a Clean Sweep |author=Michelle Krebs |work=New York Times |date=1996-12-01 |access-date=2009-09-18}}</ref>

All models used a 120-hp, [[GM 60-Degree V6 engine#LG6|3.1L V6]] mated to a 3-speed automatic transmission. In 1992, the [[Buick V6 engine#Series I|3800 Series I V6]] became available with a four speed automatic. Both were replaced by the [[GM 60-Degree V6 engine#LA1|LA1 3400 V6]] in 1996.

====1990–1996====
The vehicles in this generation included:
*[[Chevrolet Lumina APV]] ("APV" was dropped from the model name in 1994)
*[[Oldsmobile Silhouette]]
*[[Pontiac Trans Sport]]

In 1994, The Lumina and Trans Sport received a facelift, which shortened the nose and gave them a more conventional look. The Silhouette did not receive this update, however, and while it did receive a facelift in 1993, it was very minimalistic with only the front bumper being slightly changed. The rest of the front end remained unchanged.

====International====
The Pontiac Trans Sport was sold in Europe as a rebadged Oldsmobile Silhouette with European safety specifications.

European customers had grown accustomed to sleek minivans, thanks to vehicles such as the [[Renault Espace]], and did not object to the Trans Sport's futuristic styling. In 1994, when the Trans Sport was updated, the European version retained the original shape with a minor facelift, with the Oldsmobile Silhouette being sold as a badge-engineered Pontiac Trans Sport.

The European Trans Sport was also available with two options that were never offered on a North American specification U-body: A four-cylinder engine (the [[Quad 4 engine|LD2 Quad 4]]) and a 5-speed manual transmission.
