Caterpillar 308 CR vs Hyundai HX85A

The Hyundai HX85A is about 16% heavier than the Caterpillar 308 CR (9,250 vs 7,946 kg), which usually means more stability and lifting capacity but higher transport weight.

The Caterpillar 308 CR has about 6% more engine power (52 kW (70 hp) vs 49 kW (66 hp)).

Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Hyundai in your region: over the life of a machine they often matter more than small specification differences.
