Transmission Options

12M-DS / HERT-12

6-speed dog-clutch + pneumatic splitter. HERT adds H2 impulse turbine recovery (70 hp cold / 208 hp CEB) and 4 ms GDSA shifts scavenged into the intake.

9A-MC Automatic

Three planetaries, six clutches, wet launch clutch (no torque converter). Shift execution under 40 ms with skip-shift kickdown.

SVIE-V8-HR High-RPM H2 DI (3.57 L)


[ DOHC 32V LPBF Head — conformal cool + dual H2 DI ]
                      │
[ High-tumble pentroof — CR 12.5:1 ]

[ A356-T6 deep-skirt + PTWA 0.15 mm bores ]
   87×75 mm · rod 138 mm · R/S 1.84 · MPS 25 m/s @ 10k
                      │
[ Fracture-split 4600 rods · 180° flat-plane 4340 crank ]
[ Integrated 6-bolt ladder girdle ]

Honda K20/B16-evolved: long-rod, girdled bottom end, sleeveless PTWA, hybrid sand-cast block + LPBF Scalmalloy heads. Distinct from the 5.2 L gasoline SFV WOT baseline.

Anti-CVT — AXIOM Fixed-Ratio Exergy

Belt CVTs lose ~14.5 efficiency points vs dog paths and carry clamp/pump parasitics (~13.5 kW class). Honda HR-V belt TSBs and next-gen e:HEV electric CVT + S+ Shift still preserve continuous-ratio DNA. AXIOM deletes the belt; e:HEV Bridge keeps dual-motor hybrid modes without cones.

NEXUS-48 · SONIC · SENTINEL · CHRONOS

48V P1 ISG powers DEVA with margin; flat-plane 180° pulses + AETHER bark on AXIOM shifts; H2 SENTINEL 50 ms isolation; CHRONOS cold-start to first fire in 3.7 s. Repo TRL-3 with staged licensing packages.

Breakthrough Layer

CCD cryogenic densification, CASMIR acoustic chassis health (Honda AE tech transfer), PSI plasma ignition for 35:1 AFR, DKIS torsion feedforward, dual SFV/H2 co-rail, and orbital water electrolysis buffer.
