GRIP Vehicle · Full specification
The complete GRIP spec sheet — dimensions, powertrain, wheel motors, performance. But start with the one idea that makes every number below make sense: this machine wins on force, not horsepower. A 671 hp car has no business out-running a 1,500 hp hypercar — until you see how it makes its thrust.
Why horsepower is the wrong number
Horsepower measures how fast you spend energy — it wins a drag race. GRIP doesn't win that way. It wins on force, and it makes force by a completely different route than a normal car, so a modest engine does what a monster engine can't.
A Bugatti-class hypercar wrings everything out of 1,500 hp and is still held back by its tyres at launch and by a wall of air at the top. Horsepower is all it has, and most of it is wasted fighting physics it can't beat.
GRIP's 671 hp feed an electrogravitic well that turns power straight into thrust — at any speed, without the contact patch. Acceleration is limited only by what the crew can take; top speed isn't a horsepower contest at all.
A Bugatti is in a horsepower race. GRIP isn't playing that game — it makes force cheaply and at any speed, so little horsepower, enormous force. That's why every number on this page looks impossible for the power on the badge.
Thrust per kilowatt
Chemical rockets — the most powerful machines humanity makes — deliver well under one newton of thrust for every kilowatt of power. The electrogravitic drive works in a different class entirely.
Dimensions · GRIP proportions
Matched to the GRIP: Combat Racing cars — 2.5 m wheels taller than a 1.5 m body, tucked against it. Wheelbase, length and crew are carried over from the Rev D packaging study while it is re-packed to the new proportions.
| Parameter | Value | Status |
|---|---|---|
| Wheel diameter | 2.5 m | Locked |
| Tire width | 1.25 m | Locked |
| Overall height (= wheel) | 2.5 m | Locked |
| Body height (with gravity plating) | 1.5 m | Locked |
| Body width | 3.68 m at the axle line · 3.41 m at the skins | Derived |
| Floor clearance | 0.50 m, either way up | Derived |
| Track (centre to centre) | 5.17 m | Derived |
| Overall width (incl. wheels) | 6.42 m | Derived |
| Wheel travel | ±36 cm at the wheel centre, up and down | Derived |
| Wheelbase | 5.0 m | Re-packing |
| Overall length (incl. wheels) | ~7.5 m | Re-packing |
| Crew | 4 × single-person pods | Re-packing |
| Wheel speed @ 1,000 km/h | ~2,120 rpm | Derived |
| Mass, fuelled (Rev D estimate) | ~13 t | Estimate |
Powertrain & energy
Two Stoic engines make the electricity; the well and wheel motors spend it. Because cruising sips power, the plant modulates to demand — running all 500 kW would drain the tank fast and almost never happens.
| Parameter | Value | Status |
|---|---|---|
| Engines | 2 × TM-250 Stoic FPLG | Locked |
| Continuous electric power | 500 kW (671 hp) | Locked |
| Fuel-to-electricity | up to 49.9% | Target |
| DC bus | 800 V | Settled |
| Battery | 250 kWh | Locked |
| Fuel tank | 500 L (~½ tonne) | Locked |
| Battery refill at full output | ~30 min | Derived |
| Peak draw at launch (plant + battery) | ~0.6–1 MW | Estimate |
Wheel motors & drive
The well does cruise, top speed and the hard acceleration, so the wheel motors only do launch, low-speed work, reverse and regen. That means small motors with big torque — mounted in the magnetic hub, where powering them is trivial.
| Parameter | Value | Status |
|---|---|---|
| Hub casing | Keyed · 0.59 m octagon from ball to tyre, 0.56 m round inside the wheel · ~2.2 m long | Locked |
| Drive | 7 axial-flux motors stacked per hub | Locked |
| Each motor | Re-sizing for the slimmer hub | Open |
| Available per wheel | Re-sizing for the slimmer hub | Open |
| Normal use | Run 1–2 motors; more on demand | Settled |
| Powered side | Casing (stationary) — holds the stators | Locked |
| Rotating side | Internal hub + wheel — no slip rings | Locked |
| Gearing | None — direct drive | Locked |
| Role | Launch · low-speed · reverse · regen | Locked |
| Redundancy | Lose several motors, wheel still drives | Settled |
| At cruise | Motors become generators — top the battery | Settled |
Put the powered motor parts on the stationary hub and only passive magnets on the spinning rim, and power never crosses the rotating gap — no slip rings, no brushes. It's the same trick as maglev, and it also keeps the motor mass on the magnetically-sprung side, so the usual in-wheel-motor ride penalty is designed out.
Performance
Straight-line pace is limited by what the crew can take, not by the engine. Range is measured in hundreds of thousands of kilometres because the well sips power at cruise.
| Parameter | Value | Status |
|---|---|---|
| Top speed (flat terrain) | 1,000 km/h | Target |
| 0–100 km/h | <1 s (crew-limited) | Derived |
| Launch ceiling | Crew G tolerance, not power | Derived |
| Atmospheric range — one 500 L tank | ~263,000 km (gentle cruise) | Derived |
| Range on battery alone | ~30,000 km | Derived |
| Thrust per kilowatt | ~3,000× a chemical rocket | Derived |
| Target tire service life | 100,000 km | Target |
Figures are propulsion at steady cruise; real-world draw (launch, cooling, life support) trims range — still far beyond any combustion car's lifetime. Full range-vs-speed and rocket curves, and the subsystem detail, are on the vehicle page.
The spec above is built to the Rev D packaging study — four magnetic axles, the central chassis, two engines, battery, tank and four crew pods. Switch the body to see-through to inspect the packing.
