The Natural versions were introduced to the Same Dorado lineup at the end of 2018 at the EIMA exhibition. For Lamborghini, the model was called Spire Trend, and for Hürlimann, XA Spirit. The Deutz-Fahr version, the 5D Keyline, had been introduced a few months earlier. The differences between the brands were even smaller than usual. Besides the color, mainly the grille was different. The appearance was more modern than other models in the same series that were still in production, and the cab had been renewed. Only 3-cylinder models were offered. The selection of optional extras was more limited than other versions, but on the other hand, for example, the hydraulics were more powerful than those in the base models, and creep gears were standard. A speed of 40 km/h was reached at 1870 RPM. The power take-off (PTO) and four-wheel drive engagement were electronic. The front axle was equipped with disc brakes.

In autumn 2021, Stage V models were introduced, at which time urea injection was added to the two largest models. At the same time, the front end design changed slightly in all brands.
