The situation
Michael is 52, an orthopedic surgeon at Barnes-Jewish, and lives in Chesterfield with his family. He drives 15,000 miles/year: mostly hospital commutes plus weekend Ozarks trips. He's replacing a 2019 Lexus RX 350 and has narrowed his choice to two Genesis SUVs: the 2026 GV60 Standard AWD at $55,525 (with $3,000 AWD adder) and the 2026 GV70 2.5T AWD at $48,985 — same brand, same showroom, adjacent price tier.
Three things about the St. Louis market shape the analysis. First, gas at $3.99/gal is moderate — well below the $4.50/gal threshold at which luxury EV economics typically dominate in the Drive Economics library. Second, Ameren Missouri offers an Overnight Savers plan at ~$0.085/kWh (11 PM-7 AM) versus $0.125/kWh blended standard — a meaningful but not dramatic discount. Third, Missouri levies a $75/year EV decal fee ($375 over 5 years for a Standard-range EV; $759 for extended range) and Ameren offers a $500 residential charger rebate. Federal $7,500 credit expired September 30, 2025.
The question this case explores is: when a luxury EV faces a moderate-price gas market and only average electricity discount, does the operational advantage still overcome the luxury EV depreciation penalty — or does depreciation dominate as it has in prior moderate-market luxury cases?

Break-even: when the GV60 pays back its premium
The GV60 costs $7,390 more than the GV70 upfront (MSRP delta plus $1,350 charger install, minus $500 Ameren charger rebate). Charting cumulative cost year-by-year shows exactly when that premium is recovered under each Ameren rate plan.
Both GV60 scenarios cross below the GV70 in Year 3: Overnight Savers at approximately 37 months, Standard Residential at approximately 41 months. By Year 5 the GV60 cash advantage reaches $4,500 (Overnight Savers) or $3,510 (Standard) — real operational wins. But on total cost of ownership, the ~$10,000 depreciation delta between the low-volume luxury EV and the established luxury gas SUV absorbs almost all of that cash advantage. TCO narrows to $1,107 (Overnight Savers) or ties (Standard).
The 5-year math
Two GV60 scenarios shown side-by-side against the GV70 baseline. Scenario 1 assumes Michael enrolls in Ameren Missouri's Overnight Savers rate and disciplines his charging to the 10 PM-6 AM window. Scenario 2 assumes he stays on standard residential (default if he does not enroll). Both use actual St. Louis retail gas at $3.99/gallon. Missouri EV decal fee and Ameren charger rebate applied to GV60 columns.

Assumptions: St. Louis gas $3.99/gal (verified 2026-09-06); Ameren Missouri Overnight Savers off-peak $0.085/kWh (assumes 100% disciplined 11 PM-7 AM charging); Ameren standard residential blended $0.125/kWh; GV60 Standard AWD efficiency 33 kWh/100mi (EPA); GV70 2.5T AWD 22 MPG combined (EPA); Missouri EV decal fee $375 over 5 years (Standard range); Ameren charger rebate $500 applied; no federal EV credit (expired September 30, 2025); depreciation ~48% for GV70 (established luxury gas SUV retention) and ~62% for GV60 (low-volume luxury EV).

What the analysis reveals
The GV60 wins on cash but ties on TCO — the classic luxury-EV-in-moderate-market pattern. Under Overnight Savers, the GV60 saves $4,500 in 5-year cash flow but only $1,107 on TCO. Under Standard Residential, the GV60 saves $3,510 in cash but essentially ties on TCO. In both scenarios, roughly $3,400-$3,510 of cash advantage is absorbed by the $9,708 depreciation delta between low-volume luxury EV and established luxury gas SUV.
This case is where the four-condition framework predicts a near-miss. Michael's scenario has strong mileage (15,000 mi/yr) but weak values on the other three conditions: average EV efficiency (33 kWh/100mi vs the 26 threshold), moderate gas ($3.99/gal vs $4.50 threshold), and rate-discipline advantage that's meaningful but not dramatic (~32% off-peak discount vs 40% ideal). Three conditions at moderate values plus one at strength cannot overcome depreciation. The framework predicts a near-tie on TCO, and the analysis confirms it.
Rate plan discipline matters, but not enough to change the verdict. Overnight Savers enrollment is worth $990 over 5 years vs Standard Residential — real money but not decisive. Buyers who won't actively schedule charging to 11 PM-7 AM should model the Standard Residential scenario as their realistic case. Missouri's $75/year EV decal fee ($375 over 5 years) adds a modest ongoing cost the GV70 buyer doesn't face.
The generalizable finding: luxury EV economics require multiple conditions to overcome depreciation. When only one condition is strong, cash wins but TCO ties. Michael should choose the GV60 for driving experience, silent cabin, and lower ongoing operational cost — not because it demonstrably wins on TCO. If economics are the deciding factor and none of Michael's conditions strengthen materially, the GV70 is the safer TCO choice.
What could shift the analysis
- Higher mileage could flip TCO decisively toward GV60. At 20,000 mi/yr, the fuel gap grows by another $1,200/year, pushing the 5-year cash advantage past $8,000 and TCO advantage into $3,000-$4,000 territory. At 25,000 mi/yr the GV60 becomes an unambiguous economic winner. Michael's 15,000 mi/yr is right at the threshold where the analysis begins working.
- Gas price volatility swings outcomes $1,000+ over 5 years. St. Louis gas has ranged $3.20-$4.60 in the past 24 months. Sustained gas above $4.50 shifts the TCO analysis decisively toward the GV60. Below $3.50, GV70 wins cash outright.
- Genesis GV60 depreciation is the biggest unknown. The 62% estimate uses comparable low-volume luxury EV data (Lucid, Polestar). If Genesis's established luxury brand supports better resale (55% loss): TCO advantage grows to $3,500+. If GV60 depreciates like other niche luxury EVs (68%): TCO tips toward GV70. Genesis's brand equity in the used-luxury EV market is still forming.
- Federal EV credit reinstatement would flip decisively. The expired $7,500 federal credit would drop the GV60's effective price to $48,025 — below the GV70. Cash advantage would grow to $12,000+, TCO advantage to $4,500+.
- Non-financial factors deserve real weight here. The GV60 offers a smaller, sportier footprint (5-door coupe-crossover), quieter cabin, and 350 kW DC fast charging. The GV70 offers more cargo space, longer road-trip range without stops, and proven mechanical reliability. When TCO essentially ties, driving preference and use-case fit should decide. This case does not adjudicate them.
