is slower (due to cooling drag),
It may be slower, but it doesn't "ring true" to me that the cause is higher
cooling drag. Diesel engines are more efficient than gasoline engines
because they extract more of the chemical energy as useful work, and less
chemical energy is converted to waste heat. With less waste heat, their
cooling drag should be *less* than a gasoline engine's.

and carries less weight (the engine weighs more).
True.
