This SUV you’ve never heard of will drive you crazy

There are plenty of strange SUVs from the 1990s. In fact, this might be the strangest era for SUVs period. There are luxury SUVs, tiny SUVs, sports SUVs, convertible SUVs, and a whole sub-category of SUVs that looked like they had escaped from science fiction movies. But very few can do what the RMA Amphi-Ranger 2800 SR can do: leave the road, hit the dirt, then hit the water and keep going.

That alone would make the Amphi-Ranger interesting. The fact that it was built in Germany, sold as a production vehicle and developed for industrial use makes it considerably stranger. And now, one of these bizarro machines is heading to the Mecum Nashville auction, where it will have the opportunity to confuse an entirely new generation of car enthusiasts.

The Amphi-Ranger

The Amphi-Ranger was built by Rheinauer Maschinen- und Armaturenbau, or RMA, in Germany for an entire decade. From 1985 to 1995, RMA is estimated to have only produced 66 of these strange boat trucks, making it a rare bird, indeed. Despite its recreational potential, it wasn't conceived simply as a fun times machine. RMA developed the vehicle as specialized equipment for jobs that required getting across both land and water. If this seems strange or overly niche, it was. RMA wasn’t a car company; it built heavy industrial equipment for pipeline maintenance and construction. Making these strange things in-house, as niche as they are, actually made some sense. The result looked vaguely like a first-gen Mercedes G-Wagen, but underneath its aluminum body was, well, there’s really no other way to put it, a boat.

The body itself was built from seawater-resistant aluminum, and the "SR" in Amphi-Ranger 2800 SR stood for "seawater resistant." The vehicle used four-wheel drive on land and had a separate propulsion system for water. A propeller integrated into the rear of the vehicle could be electrically lowered and retracted from a dashboard switch, allowing the Amphi-Ranger to transition from SUV to boat without requiring a trailer, ramp, or second vehicle.

The 2800 SR draws power from a Ford V6, with later versions using the 2.9-liter engine. The example heading to Mecum Nashville is listed with that 2.9-liter V6, a five-speed manual transmission, four-wheel drive, locking differentials, power steering, and disc brakes. Mecum's listing also identifies it as having just 16,000 kilometers, or roughly 9,900 miles on the clock.

The numbers are almost beside the point, because the Amphi-Ranger's real party trick is its architecture. The same vehicle carries its passengers down the highway, across rough terrain, and into the water. On land, its powered axles do the work. On water, the rear propeller takes over. It's a remarkably complicated answer to a problem that most people solve by simply driving around the lake or using a boat. I guess the fine folks at RMA didn’t want to choose.

Amphibious vehicles are rare – kinda

The Amphi-Ranger belongs to a long tradition of amphibious vehicles, but it looks almost normal. Park one beside a late-'80s Ford Bronco or Mercedes-Benz G-Class and it wouldn't immediately announce itself as a James Bond car. Then you notice the shape of the body, the hardware underneath and, presumably, the moment when someone starts lowering a propeller out of the rear.

As we mentioned earlier, only about 66 Amphi-Ranger 2800 SRs are believed to have been built, making the vehicle exceptionally rare. As strange and rare as this one is, Amphibious vehicles have been made for a long time and still are being made by a number of boutique builders in a truly shocking array of configurations, styles, and levels of practicality. The Mecum example steps things up a bit in the rarity dept., because it’s believed to be the only 1990 model currently in the United States. It is scheduled to cross the block at Mecum Nashville on Sept. 26, 2026. 

It is tempting to look at something like this and wonder what problem its engineers were trying to solve and then make fun of it for picking the most complicated solution. That's actually the wrong way to look at something like this. In fact, questioning its existence at all is heading in the wrong direction entirely. We didn’t use to do this so much. Questioning why something was made instead of enjoying the simple fact that it was made is, in part, what has led to the increasing snoozefest that is the modern car market. In 1990, even the Germans were making wild stuff. The GERMANS! 

The Amphi-Ranger isn't merely weird because it can float. It's weird because somebody decided that being able to float was useful enough to justify building a vehicle around the idea. That sort of thinking produced some of the most interesting machines of the late 20th century, and it is getting harder to imagine a company taking a swing like this today. Which makes this 1990 RMA Amphi-Ranger a fun and extremely strange auction lot.
