Which type of snowmobile engine is generally considered more eco-friendly?

The newer four-stroke engines are generally considered more eco-friendly due to their design and operational efficiency. Four-stroke engines typically produce fewer exhaust emissions compared to older two-stroke engines, which can burn oil along with fuel, resulting in higher levels of pollutants being released into the atmosphere. Additionally, four-stroke engines tend to have better fuel efficiency, leading to less fuel consumption and, consequently, a lower carbon footprint for the same amount of energy produced.

Furthermore, advancements in technology with newer models have focused on minimizing environmental impact, including features that reduce noise and harmful emissions further. The improved combustion process in four-stroke engines allows them to operate more cleanly, making them a more sustainable choice for snowmobiling. This aligns with growing environmental regulations and the push for cleaner recreational vehicles.
