We present the first fully explicit, continuous, analytically derived warp–drive spacetime within General Relativity whose shift–vector flow is kinematically irrotational. Building on Santiago et al. that scalar–potential, zero–vorticity warp fields are Hawking–Ellis Type I for unit lapse and flat spatial slices, we supply a closed–form scalar potential and smooth shift components with proper boundary behavior, together with a Cartan–tetrad analytic pipeline and high–precision eigenanalysis. Compared with the Alcubierre and Natário models (evaluated at identical \((\rho ,\sigma ,v/c)\) ), our irrotational solution exhibits significantly reduced local NEC/WEC stress: its peak proper–energy deficit is reduced by a factor of \(\approx 38\) relative to Alcubierre and \(\approx 2.6\times 10^{3}\) relative to Natário, and its peak NEC violation is more than \(60\times \) smaller than Natário. Crucially, the stress–energy is globally Hawking–Ellis Type I, with a well–defined timelike eigenvalue (proper energy density) everywhere. A fixed–smoothing vortical ablation confirms that this improvement is causally due to irrotational, curl–free kinematics rather than profile shaping: adding modest vorticity collapses the \(E_{+}/E_{-}\) balance and drives large increases in the negative–energy magnitude \(E_{-}\) . We quantify the negative–energy requirement via a slice-integrated (on \(\Sigma _t\) ) negative–energy volume and tabulate global measures. A far–field extrapolation to \(R\!\rightarrow \!\infty \) yields tail–corrected totals \(|E_+-E_-|/(E_++E_-)=0.04\%\) . Thus the net proper energy is consistent with zero to four decimal places (in fractional units). We also establish regularity at \(r=0\) for the irrotational construction.
