  We report on the recent results of the hypercentral Constituent Quark Model
(hCQM). The model contains a spin independent three-quark interaction which is
inspired by Lattice QCD calculations and reproduces the average energy values
of the SU(6) multiplets. The splittings are obtained with a SU(6)-breaking
interaction, which can include also an isospin dependent term. Concerning
Constituent Quark models, we have shown for the first time that the decreasing
of the ratio of the elastic form factors of the proton is due to relativistic
effects using relativistic corrections to the e.m. current and boosts. Now the
elastic nucleon form factors have been recalculated, using a relativistic
version of the hCQM and a relativistic quark current showing a very detailed
reproduction of all the four form factor existing data over the complete range
of 0-4 $GeV^2$. Futhermore, the model has been used for predictions concerning
the electromagnetic transverse and longitudinal transition form factors giving
a good description of the medium $Q^2$ behaviour. We show that the
discrepancies in the reproduction of the helicity amplitudes at low $Q^2$ are
due to pion loops. We have calculated the helicity amplitudes for all the 3 and
4 star resonances opening the possibility of application to the evaluation of
cross sections.
