Ioniq 5 vs. Tucson Hybrid in Chicago.

The situation

Amanda is 38, works as an analytics manager at a mid-sized bank headquartered in the Loop, and lives in Naperville with her husband and two elementary-school-age kids. Her commute is a hybrid pattern: two office days per week she drives to the Naperville Metra station and rides the BNSF train downtown, and three days per week she works from home. Weekend driving covers school pickups, grocery runs, visits to family in Oak Park, and occasional weekend trips to Galena or southeast Wisconsin. Her 2019 Honda CR-V has 84,000 miles and is starting to need more meaningful maintenance intervention. She wants to replace rather than repair, and she prefers the crossover form factor she's been driving.

Her annual mileage lands around 12,000 miles, modest for a suburban Chicagoland family because Metra absorbs the weekday commute and most weekend driving stays within a 30-mile radius. She's specifically cross-shopping the 2026 Hyundai Ioniq 5 SE Standard Range ($35,250) against the 2026 Hyundai Tucson Hybrid Blue AWD ($32,800). Same brand, same dealer network, essentially identical crossover footprint. The Ioniq 5 costs $2,450 more at sticker, but Illinois offers a $2,000 EPA rebate on the electric side, narrowing that gap to $450 after incentives.

Two things about Chicago make this analysis different from most markets we've documented. The first is ComEd's Rate BEST, a structured time-of-use rate specifically designed for EV owners with the discipline to charge overnight. Between 10 PM and 6 AM, off-peak power runs approximately 4.5¢/kWh — the cheapest documented electricity rate in the Drive Economics library. During weekday peak hours (2 PM to 7 PM), that same rate can climb to 32¢/kWh or higher. The rate structure creates enormous financial variance depending on when a driver chooses to charge. For a garage-parked household with a Level 2 charger and a routine of plugging in at bedtime, capturing the off-peak rate is straightforward and the fuel economics become exceptional. For a household with opportunistic daytime charging (work-from-home schedules, spontaneous top-ups after errands), the same rate structure can actually cost more than the standard residential rate.

The second is cold-weather physics. Real-world EV range in Chicago winters degrades meaningfully — published research from Recurrent and the Idaho National Laboratory documents 15-25% range loss for most EVs when ambient temperatures drop below 20°F. The mechanism is a combination of battery efficiency loss (lithium-ion chemistry moves ions more slowly at low temperatures) and cabin heating draw. The Ioniq 5 SE Standard Range does not include a heat pump on the 2026 SE trim, so its winter derate lands closer to the middle of that range: approximately 18-20% degradation averaged across November through March. Compounded over the entire year (five months of degradation), the effective annual consumption rises from a baseline 25-26 kWh/100mi to roughly 29.3 kWh/100mi. That degrade is already priced into the analysis below.

A third factor, less structural but currently significant: gas prices are elevated. The Chicago metropolitan area retail price on the date this case is written trades at approximately $4.39/gallon, materially higher than the $3.85 Midwest regional average our default calculator draws from. This reflects ongoing Iran-related crude disruptions that continue to elevate Chicago retail prices meaningfully above regional averages. For this analysis we anchor to observed Chicago retail, not regional averages. Historical patterns suggest volatility persists in both directions; buyers making a 5-year decision should weight their read of medium-term gas price trajectories, not just the day's posted number.

The vehicles

The 5-year math

Two scenarios shown side-by-side. Scenario 1 assumes disciplined off-peak charging under ComEd Rate BEST. Scenario 2 assumes ComEd Standard Residential Rate, which represents opportunistic or undisciplined charging patterns. Both scenarios use actual Chicago retail gas at $4.39/gallon.

Assumptions: Chicago metropolitan area regular gasoline at $4.39/gal (retail observation 2026-09-01, elevated above $3.85 Midwest regional average due to ongoing crude price disruptions). ComEd Rate BEST Scenario: overnight super-off-peak $0.045/kWh for 10 PM to 6 AM charging with 100% of energy captured in that window (represents disciplined garage-parked charging routine). ComEd Standard Residential Scenario: blended residential rate $0.163/kWh, representing opportunistic charging patterns or households without garage access. Ioniq 5 effective consumption 29.3 kWh/100mi, incorporating 18% winter derate averaged across November through March (SE Standard trim does not include heat pump; heat pump-equipped Limited trim would show 24-26 kWh/100mi effective). Tucson Hybrid 38 MPG combined applies year-round; hybrid systems show minimal cold-weather MPG variance. Illinois EPA EV rebate $2,000 standard tier (Ioniq 5 SE at $35,250 qualifies without MSRP cap issues; income-eligible tier at $4,000 not applied). Federal EV credit is zero (expired September 30, 2025). Level 2 charger installation at $1,350 (standard home upgrade, no service panel replacement). Insurance from density-and-MSRP model for Cook County ZIP 60540 with Illinois state premium adjustment. Maintenance from Hyundai-brand baselines for crossover segment. See methodology.

What the analysis reveals

Charging discipline is a $2,075 variable in this analysis. The difference between ComEd Rate BEST at 4.5¢/kWh off-peak and ComEd's standard residential rate at 16.3¢/kWh accounts for a 3.6-fold difference in per-kWh cost. For Amanda's 12,000 mile/year usage with the Ioniq 5's 29.3 kWh/100mi effective consumption, that translates to $415 per year of variability, or $2,075 over the 5-year horizon. This is the largest single-variable sensitivity in the analysis — larger than the impact of Illinois's rebate, larger than the impact of moderate gas price movement, and larger than reasonable variance in insurance or maintenance estimates.

Gas price elevation compresses the discipline sensitivity. At $4.39/gal, the Tucson Hybrid consumes $6,932 in fuel over 5 years — roughly $857 more than the same calculation would show at the calculator's default $3.85 Midwest regional average. That elevated gas cost partially offsets the penalty of undisciplined EV charging: in the Standard Rate scenario, the Ioniq 5 still comes out $3,466 lower than the Tucson Hybrid because current gas prices make the hybrid's fuel burn expensive. If gas retreats to $3.50/gal (below current averages, plausible if geopolitical conditions ease), the Standard Rate scenario compresses further — to roughly a $2,700 Ioniq 5 advantage. If gas rises to $5.00/gal (also plausible if Iran-Israel tensions escalate), the Standard Rate scenario opens to roughly $4,900. The range of scenarios brackets the analysis at roughly $2,700 to $5,900 Ioniq 5 lower under Standard Rate charging, and $4,700 to $7,600 Ioniq 5 lower under Rate BEST discipline.

Cold-weather derate is priced in but structurally worth understanding. The 18% winter degradation on the Ioniq 5 SE (no heat pump) costs Amanda approximately $80 per year in additional electricity under Rate BEST discipline, or $290 per year under Standard Rate. Over 5 years, that's $400 to $1,450 depending on rate discipline. For a buyer prioritizing cold-climate resilience, the Ioniq 5 Limited trim (which includes a heat pump) would reduce this derate by roughly half. The Limited trim adds approximately $5,500 to MSRP, however, so the trim upgrade rarely pays back on winter performance alone; it pays back through creature comforts (heated steering wheel, better audio, larger battery). The Limited trim also loses the Illinois EPA rebate if MSRP exceeds the state's cap, though at $40,750 base the trim currently sits under that threshold.

The Tucson Hybrid's structural strengths remain relevant. Nothing in this analysis diminishes what the Tucson Hybrid offers: 38 MPG that holds consistently across seasons, no charging infrastructure requirement, no dependency on off-peak rate windows or garage access, familiar refueling patterns, and lower insurance premiums. For a household without a garage, without predictable overnight parking, or for whom "just fill it up on the way home" is a fundamental preference, the Tucson Hybrid delivers stability the Ioniq 5 cannot match. The $3,500 to $5,500 nominal cost advantage of the Ioniq 5 in this analysis assumes home charging infrastructure that not all buyers have realistic access to. Renters, condo residents without dedicated parking, and households with unpredictable schedules should weight the Tucson Hybrid's operational simplicity heavily against the Ioniq 5's financial advantage.

How this case relates to others in the library. The Ioniq 5 vs. Tucson comparison has been documented in Seattle earlier this year, under Puget Sound Energy's residential rates and Washington State's $9,000 EV incentive combined with fresh 2025 federal support. That analysis produced a much wider EV advantage — close to $9,000 over 5 years — driven by the combination of state and federal incentive stacking, cheaper electricity, and milder climate. Chicago represents a materially different environment: federal support removed, state rebate smaller, colder climate, but exceptional utility rate design available for disciplined users. The two Chicago Ioniq 5 scenarios ($3,466 lower to $5,540 lower depending on charging discipline) sit meaningfully below the Seattle result, primarily because federal credit expiration removed $7,500 of direct incentive from every Illinois EV analysis. Buyers evaluating this comparison in any market should treat the federal credit environment as the largest single input variable, followed by their local utility's EV rate design.

What could shift the analysis

• Federal EV credit reinstatement. If the federal $7,500 credit returns through legislation or executive action, both Ioniq 5 scenarios extend by that amount — the Rate BEST scenario extends to approximately $13,000 Ioniq 5 lower over 5 years, and the Standard Rate scenario to approximately $11,000 Ioniq 5 lower. Illinois represents a market where restored federal support would compound with strong state and utility economics to produce a genuinely one-sided analysis. This is the largest single potential variable, though political timing remains uncertain.
• Gas price movement is the second-largest sensitivity. Historical Chicago retail has ranged from $2.75/gal (deflated periods) to $5.30/gal (peak crisis moments). Over a 5-year ownership horizon, the mean will likely differ from today's $4.39 observation, in either direction. Modeling the Ioniq 5 advantage at $3.00/gal produces roughly $700 Ioniq 5 lower under Standard Rate; at $5.50/gal it produces roughly $5,700 lower. Households buying today are effectively hedging against future gas volatility — an argument in the Ioniq 5's favor if they have any conviction gas prices trend higher.
• ComEd Rate BEST discipline is achievable but not automatic. The 4.5¢/kWh figure requires 100% of charging to occur between 10 PM and 6 AM. Real-world households with home Level 2 chargers achieve 85-95% off-peak capture in Recurrent survey data. At 85% capture and 15% at peak rates (roughly 32¢/kWh under Rate BEST), the effective blended rate rises to approximately 8.6¢/kWh — still far cheaper than standard residential but with 5-year electricity cost of roughly $1,510 rather than $791. That would reduce the Ioniq 5 advantage in the discipline scenario from $5,540 to approximately $4,820. Real-world outcomes likely sit somewhere between the two scenarios shown in the table.
• Ownership horizon matters differently in each scenario. The Rate BEST scenario's $5,540 advantage accumulates gradually — roughly $1,100 per year of the 5-year horizon. At 3 years, that advantage compresses to approximately $3,300; at 10 years, it extends to approximately $11,100. The Standard Rate scenario shows a shallower slope because higher electricity costs compress the annual fuel savings. Longer-tenure households capture more of the EV advantage in the disciplined scenario; shorter-tenure households (roughly 3 years or less) should treat this analysis as marginal rather than decisive.
• Cold-weather considerations extend beyond efficiency. The 18% winter derate on Ioniq 5 range means Amanda's effective winter range drops from 220 EPA to roughly 180 miles — still adequate for her 12,000 mile/year usage pattern, but with less cushion for the occasional Galena or Wisconsin trips. For households with regular 200+ mile single-day driving requirements in winter months, the Tucson Hybrid's unlimited refueling flexibility becomes a genuine operational advantage independent of cost. This is not captured in the ownership cost table but should factor into the decision.
• Trim upgrades change the analysis meaningfully. The Ioniq 5 SE Standard Range at $35,250 is the entry point that qualifies cleanly for Illinois's rebate. Upgrading to the Limited trim ($40,750) retains the rebate but adds $5,500 to MSRP, shrinking the advantage over Tucson Hybrid Blue by roughly that amount. The Tucson Hybrid Limited trim ($36,500) approaches the Ioniq 5 SE's price point, at which point the analysis becomes closer to the Seattle case study where sticker-price parity plus EV incentives produce a wider EV advantage. Buyers cross-shopping specific trim combinations should recalculate rather than assume this analysis transfers directly.
