Features of the Unique Prototype
According to reports, Porsche Engineering modified a 2018 Polaris RZR XP Turbo S for testing during the development process. This unique specimen features a conversion to rear-wheel drive, suspension from KW, and brake components from Porsche and Audi. Although the vehicle is supposedly road-legal in Arizona, this special prototype is now up for auction on Cars & Bids.
A Rare Occurrence in the Automotive Industry
Automakers regularly create development vehicles that never make it past the testing phase. Even brands like Polaris do the same. However, it is rare for any of these cars to see the light of day after testing is completed. They usually end up being scrapped or in a museum.
According to the seller, this is exactly what this Polaris RZR represents, and if true, it is not an ordinary prototype but a unique collaboration with Porsche Engineering that can actually be purchased.
Technical Details and Modifications
At its core, this vehicle is still based on a 2018 Polaris RZR XP Turbo S with the standard 0.9-liter two-cylinder engine producing 168 horsepower (125 kW) and a continuously variable transmission. However, from there on, everything differs from the production RZR. This becomes obvious at first glance, but let’s break down just how different this multi-passenger off-roader is.
Unusual Engineering Solution
According to the seller on Cars&Bids, Porsche Engineering modified it and never planned to show it to the public.
For example, the chassis has been stretched using parts from the four-seat model. A huge rear wing is installed at the back. Inside, this RZR received seats from a Porsche 911 GT3 RS of the 997 generation. Since they are positioned much lower than the standard seats, the dashboard is also lower than the production one. A roll cage protects both the passengers and the relocated fuel cell.
The entire structure is mounted on a custom KW Automotive suspension and 18-inch wheels. Porsche actually removed the electronic power steering system and replaced the front hubs with those from a Volkswagen Passat.
The front brakes are taken from an Audi R8 sports car, and the calipers are from a Porsche Cayenne S. Oh, and there is one more major feature: this RZR is strictly rear-wheel drive, so it can drift and do donuts like the best of other RZR models.
Current Condition and Possibilities
Despite its Arizona registration, which makes it road-legal, this is not a flawless machine. It still rides on 2018 tires, the dashboard lights up like a Christmas tree, the speedometer shows incorrect readings, and there are many paint marks and scratches on the exterior. Nevertheless, it’s hard to imagine a more extreme way to tempt fate on four wheels.
This prototype not only showcases the possibilities of collaboration between different engineering schools but also becomes a unique example of how test mules can get a second life. Its technical solutions, such as the use of components from various brands, highlight the importance of adaptation and innovation in automotive design, even for niche products like multi-passenger off-roaders.
