This paper introduces the Meyler-Fuchs Hybrid Warp Drive (MFHD), a finite, positive-energy, subluminal warp metric built on a toroidal plasma shell with classical GRMHD sourcing. The design hybridizes the torsion-lowering M¨obius-parity ansatz from Meyler’s TEPWD framework with the positiveenergy, shift-based constructions of Fuchs and Lentz, enforcing strict guard inequalities that prevent closed timelike curves (CTCs) and superluminality. We then present H-MFHD, a hyperbolic-shift reformulation that replaces static shift fields with dynamically evolving potentials governed by anisotropic wave equations, ensuring causal propagation and numerical well-posedness. Following the Time- Machine Design and Evaluation Checklist (Meyler, 2025), we provide complete derivations of the metric, curvature tensors, stress-energy decomposition, energy conditions, geodesic structure, stability analysis, and semiclassical consistency. We prove steady-state equivalence between MFHD and H-MFHD, derive sufficient conditions for theWeak and Null Energy Conditions, and formulate a PDE-constrained optimization that minimizes boundary gradients subject to guard inequalities. Numerical benchmarks show that hyperbolic shaping yields ∼25% energy reduction beyond the M¨obius-thick-wall baseline, and that splitting transport across two orthogonal shift axes can halve the required energy for curvature exponents p ≥ 4. The MFHD/H-MFHD framework is shown to be a finite-device candidate with explicit engineering gates, classical stability, and manageable semiclassical backreaction timescales.
