The quick one — 54 gas horsepower for when the RTV needs to cover ground.

The RTV-XG850 trades the RTV-X's diesel torque for gas horsepower, 54 HP with a CVT Plus transmission, so it covers ground faster. That's why it's a strong fit for trail riding and hunting camp duty rather than pure work-duty hauling.
It's built more for speed and trail use than heavy work-duty hauling. If covering ground quickly for hunting, trail riding, or general property use is the priority, the XG850 fits well; for daily farm chores and towing, the diesel RTV-X is the better match.
The RTV-XG850 is a 2-seat utility vehicle, focused on driver-and-passenger trail and recreational use rather than crew hauling.
It uses Kubota's CVT Plus transmission, which is tuned for smoother power delivery at speed, compared with the hydrostatic VHT or VHT-X transmissions in the diesel RTV lineup.
Gas engines like the one in the XG850 tend to be lighter and quicker to rev, which suits speed-focused trail and recreational use. Diesel models like the RTV-X trade some of that quickness for better fuel efficiency and torque under sustained work loads.
