Grok cost estimats for 2025 YoMobil

Cost Breakdown for a 2025 e-Rex YoMobile Hybrid

This post details the **costs and financials** for a 2025 U.S.-made compact hybrid sedan combining the **INNengine e-Rex engine** (500cc, ~84 lbs, 120 hp) and **YoMobile series hybrid concept** (dual FWD motors, no transmission). Targeting a **~$19,000 retail price**, ~2,365 lbs, and ~36–38.8 MPGe, it aims for ~320,000–480,000 units/year (11–17% of ~2.8M sub-$25,000 segment), akin to a Dodge Neon (~$19,000–$25,000 in 2025 dollars). Costs reflect U.S. production, 2025 tariffs, incentives, and multi-industry e-Rex sales (aviation, motorcycles, marine).

Vehicle Specifications and Retail Price

The hybrid uses a high-strength steel (HSS) frame, recycled fiberglass body, dual FWD motors (~150 lb-ft), 1.5 kWh battery (~6-mile electric range), and AC. Key specs:

**Weight**: ~2,365 lbs
**Performance**: ~36–38.8 MPGe, ~7–7.5 seconds 0–60 mph
**Retail Price**: **~$19,000**, absorbing ~$0–$3,900/unit loss (comparable to early EV strategies, ~$10,000/unit)
**Production Volume**: ~300,000 units/year (cars), ~430,000–570,000 total e-Rex units (including ~130,000–270,000 for aviation, motorcycles, marine)

Fixed Costs

Fixed costs cover R&D, factory, tooling, and licensing, amortized over 300,000 units/year, with 2025 grants and multi-industry subsidies.

**R&D**: ~$650M (engine: $300M, hybrid: $150M, design: $200M)
**Factory**: ~$1.5B (U.S., ~500,000-unit capacity, 35% savings via automation)
**Tooling**: ~$80M (HSS, fiberglass molds, shared across industries)
**Licensing**: ~$75M (INNengine)
**Grants**: ~$250M (2025 DOE programs), reducing to ~$2.055B
**Subsidy**: ~$100M (from ~$50M–$105M aviation/motorcycle/marine profit), reducing to ~$1.955B
**Amortized**: $1.955B ÷ 300,000 = **~$6,517/unit**

Variable Costs

Variable costs include components, labor, and logistics, offset by 2025 incentives for U.S. production.

**e-Rex Engine**: ~$225 (~84 lbs, ~100–150 parts, ~$200–$250 at ~500,000 units)
**Hybrid System**: ~$3,503 (generator: ~$1,800, dual FWD motors: ~$1,080, 1.5 kWh battery: ~$225, inverter: ~$400)
**Chassis/Body**: ~$2,200 (HSS frame: ~$1,500, fiberglass panels: ~$1,800, wheels: ~$400)
**Interior/Safety**: ~$1,750 (airbag: ~$600, ABS: ~$300, seats: ~$350, radio: ~$100, AC: ~$500, windows: ~$100)
**Brakes/Suspension**: ~$600 (brakes: ~$300, suspension: ~$300)
**Other**: ~$700 (tires: ~$250, misc.)
**Labor**: ~$424 (8 hours at ~$53/hour, automated assembly)
**Logistics**: ~$700 (distribution, minimal marketing)
**Incentives**: ~$1,200/unit (2025 tax breaks, hybrid credits, tariff exemptions)
**Total**: $10,278 + $424 + $700 – $1,200 = **~$10,202/unit**

Total Cost and Retail

Combining fixed and variable costs yields the break-even cost, with retail set to compete with budget cars (~$17,000–$23,000).

**Break-Even**: $6,517 (fixed) + $10,202 (variable) = **~$16,800/unit**
**Retail**: **~$19,000**, absorbing ~$0–$3,900/unit loss, feasible at ~300,000 units/year
**2030 Savings**: HSS ~$0.75/lb (~$1,000 frame), fiberglass ~$1/lb (~$1,000), saves ~$1,700, reducing to **~$15,100/unit**

Multi-Industry e-Rex Economies

Producing ~130,000–270,000 e-Rex units/year for aviation (~20,000–50,000, ~$15M–$37.5M revenue), motorcycles (~50,000–100,000, ~$25M–$50M), and marine (~30,000–60,000, ~$22.5M–$45M) alongside ~300,000 for cars (~$225/unit) scales total production to ~430,000–570,000 units/year. This cuts e-Rex costs (~$270 to ~$225, ~20–25% savings) and generates ~$50M–$105M profit (~$500–$750/unit OEM price), subsidizing car fixed costs (~$100M, ~$333/unit).

Financial Viability

At ~$19,000, the hybrid targets ~320,000–480,000 units/year (11–17% of ~2.8M sub-$25,000 segment), rivaling Corolla (~$23,000, ~200,000 units). 2025 tariffs (25% on Mexico) add ~$500–$1,000/unit to imports (e.g., Versa, ~$17,000), while ~$1,200/unit incentives (tax breaks, credits) and ~$2,500–$4,500 income growth (2025 policies, ~$90,000 median) make ~$19,000 ~20–21% of income, affordable for ~55–65% of households. Multi-industry e-Rex sales (~$77.5M–$162.5M revenue) ensure profitability, supporting ~$19,000 retail.
