About the 2026 Mercedes-Benz EQS

The Mercedes-Benz EQS is the most aerodynamic production car ever built (0.20 Cd) and the electric equivalent of the S-Class flagship. Its 56-inch MBUX Hyperscreen and up to 350 miles of range redefine what a luxury EV can be.

Advantages

✓Best-in-class aerodynamics (0.20 Cd) significantly extends highway range

✓MBUX Hyperscreen is the largest automotive display ever produced

✓Rear Axle Steering provides limo-like maneuverability despite enormous size

✓Massage seats and Burmester 3D sound available — true flagship experience

Considerations

✗$104,400+ price is a difficult justification when Tesla Model S offers similar range for $40K less

✗Software complexity means the MBUX system can feel overwhelming

✗Relatively modest 200 kW DC fast charging for the price tier

✗Divisive exterior design lacks the drama of some competitors

Ideal Buyer

S-Class loyalists transitioning to electric. Buyers who value the absolute finest cabin materials, rear-seat luxury, and aerodynamic efficiency above all.

vs. Gas Equivalent

Direct EV equivalent of the Mercedes-Benz S-Class 580. Gas equivalent is a Mercedes S550 at approximately 21 MPG.

EV Ownership in Illinois

Illinois, led by Chicago, is a major EV market. The Chicago metro area has strong EV adoption, particularly in the northern suburbs. State EV policy has been increasingly supportive with new incentive programs.

Incentives & Programs

Illinois offers the Illinois Electric Vehicle Rebate (up to $4,000 for eligible buyers through the Illinois EPA). ComEd offers a Level 2 charger rebate and off-peak EV rates. The state also exempts EVs from a portion of annual registration fees.

Charging Infrastructure

Chicago and suburbs have strong DCFC coverage. I-90 and I-88 corridors are well-served. Downstate Illinois (Springfield, Peoria, Champaign) is growing. Some rural stretches still have limited coverage.

Grid & Energy Source

Illinois' grid is ~54% nuclear (the highest of any state), with natural gas and growing wind. Nuclear dominance means Illinois EV charging is among the cleanest in the Midwest, despite the high reliance on an older grid mix.

IllinoisElectricity Rates & EV Savings

The average residential electricity rate in Illinois is $0.17/kWh, which is at the national average of $0.17/kWh. With a gas price of $3.90/gallon, Illinois ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your Mercedes-Benz EQS's 108 kWh battery provides up to 350 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.
