  The key feature of nonlocal kinetic energy functionals is their ability to
reduce to the Thomas-Fermi functional in the regions of high density and to the
von Weizs\"acker functional in the region of low density/high density gradient.
This behavior is crucial when these functionals are employed in subsystem DFT
simulations to approximate the nonadditive kinetic energy. We propose a GGA
nonadditive kinetic energy functional which mimics the good behavior of
nonlocal functionals retaining the computational complexity of typical
semilocal functionals. The new functional reproduces Kohn-Sham DFT and
benchmark CCSD(T) interaction energies of weakly interacting dimers in the
S22-5 and S66 test sets with a mean absolute deviation well below 1 kcal/mol.
