Obviously it is not the same an 1.6 like and a 5.7. it is another world in fact. But most small engines should accelerate uphill with not issues. Problem normally is people tend to drive his cars at way too low rpms. The optimal regime for gasoline engines is usually around 4000 rpm, and for diesel 3000 rpm. Driving at 1500 rpm leads to poor torque, lots of dirt in manifold and valves, and even general damage to the engine, specially if it is turbocharged, as small displacement engines use to be. And btw fuel consumption is not that better either.
