Efficient and low-emitting engines
The newest motor graders from Caterpillar, the Cat 120M2 and 12M2 and their all-wheel-drive (AWD) counterparts, the 120M2 AWD and 12M2 AWD, are equipped with low-emitting, fuel-efficient engines meeting Tier 4 Interim emission standards and are designed for a broad range of tasks. The new M Series 2 models are powered by Cat VHP (variable horsepower) engines with ACERT Technology and all have wider net-horsepower ranges than their M Series predecessors. The 120M2 and 120M2 AWD use the C7.1 ACERT engine, and the 12M2 and 12M2 AWD the C9.3 ACERT engine. Maximum net power ratings for the new models, respectively, are 189 horsepower (141 kW), 209 horsepower (156 kW), 223 horsepower (166 kW) and 243 horsepower (181 kW).
