What the Mercedes EQS 450 Electric Is
The Mercedes EQS 450 is a full-size luxury sedan powered entirely by electricity, with no gasoline engine. It seats five adults, offers a driving range of roughly 260 to 280 miles per charge depending on driving conditions and which model year you're looking at, and accelerates from zero to 60 mph in approximately 5.5 seconds. The battery sits beneath the floor, which lets Mercedes design a flat interior with more legroom than traditional sedans.
This is Mercedes's flagship electric vehicle — the company's answer to the Tesla Model S and Porsche Taycan. It comes with a 107.8-kilowatt-hour battery pack (the usable portion is smaller), an 8-speed automatic transmission, and standard all-wheel drive on most trims. The 450 designation refers to the power output, not engine size; it's the entry-level EQS, with more powerful versions available.
The EQS 450 starts around $105,000 before any incentives, though prices vary by model year, region, and dealer. Federal tax credits of up to $7,500 may lower the effective cost if you meet income and vehicle-price caps set by the U.S. government. Some states offer additional rebates.
Key Takeaways

Range, Charging Speed, and Real-World Driving
The EPA rates the EQS 450 at 260 to 280 miles of range, depending on the model year and whether you choose rear-wheel or all-wheel drive. This figure assumes mixed city and highway driving under moderate conditions. In cold weather, expect that range to drop by 20 to 40 percent — a 260-mile car might deliver 150 to 200 miles in freezing temperatures. Highway driving at 70 mph or higher also cuts range faster than city driving.
Charging at home with a Level 2 charger (240 volts, typically a wall-mounted unit) takes 10 to 12 hours for a full charge from empty. Most owners charge overnight and start each day with a full battery. DC fast charging at public stations can add 200 miles in roughly 30 minutes, though charging speed slows as the battery approaches full capacity. The last 10 to 20 percent of charge takes significantly longer than the first 80 percent.
Mercedes includes a mobile connector that works with standard 120-volt outlets, though this method is slow — expect 2 to 3 miles of range per hour of charging. Most EQS owners install a dedicated Level 2 charger at home for practical daily use.
Interior Space, Comfort, and Technology
The EQS has a 56-inch curved display that combines the instrument cluster and infotainment screen into one seamless panel. The interface runs Mercedes's MBUX system, which includes voice control, smartphone integration via Apple CarPlay and Android Auto, and over-the-air software updates. Navigation includes real-time traffic and can route you through charging stations.
The flat floor created by the under-body battery means rear passengers get more legroom than in traditional sedans — roughly 38 inches of rear knee space. The trunk holds 22 cubic feet of cargo with the rear seats up, expandable to 63 cubic feet with them folded. There is no frunk (front trunk) because the motor and power electronics occupy that space.
Standard features include leather upholstery, power-adjustable front seats with heating, dual-zone climate control, and a 13-speaker sound system. Higher trims add massaging seats, panoramic sunroofs, and upgraded audio. The cabin is quieter than gas-powered cars because there is no engine noise, though tire and wind sound become more noticeable at highway speeds.
Performance and Handling
The EQS 450 produces 329 horsepower and 354 pound-feet of torque. It accelerates from zero to 60 mph in about 5.5 seconds — quick for a luxury sedan but not sports-car fast. The weight of the battery pack (roughly 1,000 pounds) sits low in the chassis, which lowers the center of gravity and improves handling compared to traditional sedans of similar size.
The suspension uses a multi-link independent setup with adaptive damping on most trims, meaning the car adjusts stiffness automatically based on road conditions and driving mode. You can choose between Eco, Comfort, Sport, and Individual modes, each tuning the throttle response, steering weight, and suspension firmness differently.
Regenerative braking captures energy when you slow down and feeds it back to the battery, extending range. In Eco mode, lifting off the accelerator slows the car noticeably through regeneration alone, reducing the need to use the friction brakes. This one-pedal driving takes practice but becomes natural for most drivers.
Warranty, Maintenance, and Long-Term Costs
Mercedes covers the EQS with a 4-year, 50,000-mile basic warranty and an 8-year, 100,000-mile battery warranty. The battery warranty covers defects and degradation beyond a certain threshold — typically 70 percent of original capacity — though the exact terms vary by region. Most EQS batteries retain 85 to 95 percent of their original capacity after 100,000 miles under normal use.
Maintenance costs are lower than gas cars because there is no oil, spark plugs, timing belts, or transmission fluid to service. Brake pads last longer due to regenerative braking. Tire wear is the main consumable expense, and tires on electric cars wear faster than on gas cars because of the weight and when ready torque. Expect to replace tires every 25,000 to 40,000 miles depending on driving style.
Electricity costs roughly one-third to one-half the price of gasoline per mile, depending on local electricity rates and your charging method. Charging at home during off-peak hours is cheapest; public DC fast charging is more expensive but necessary for long trips.
How the EQS 450 Compares to Other Electric Sedans
| Vehicle | Starting Price | EPA Range | 0–60 Time | Seating |
|---|---|---|---|---|
| Mercedes EQS 450 | ~$105,000 | 260–280 miles | 5.5 seconds | 5 |
| Tesla Model S (Long Range) | ~$75,000 | 405 miles | 3.2 seconds | 5 |
| Porsche Taycan (Base) | ~$80,000 | 225 miles | 5.1 seconds | 4 |
| BMW i7 (xDrive50) | ~$111,000 | 324 miles | 4.6 seconds | 5 |
| Lucid Air (Pure) | ~$70,000 | 420 miles | 4.5 seconds | 5 |
The EQS 450 sits in the upper-middle range of luxury electric sedans by price but offers less range than the Tesla Model S or Lucid Air at lower starting prices. It accelerates faster than the Porsche Taycan base model but slower than the BMW i7. The EQS emphasizes interior comfort and technology over raw performance or range-per-dollar value.
If range is your priority, the Tesla Model S Long Range and Lucid Air both offer significantly more miles per charge at lower prices. If you prioritize luxury interior design and Mercedes's brand reputation, the EQS 450 delivers that at the cost of higher price and shorter range. The Porsche Taycan is sportier but smaller and more expensive for less range.
Charging Infrastructure and Trip Planning
The EQS 450's 260 to 280-mile range means most daily driving requires no charging outside your home. For road trips, you'll need to plan charging stops. The Mercedes navigation system shows charging stations along your route and can reserve a spot at some networks. Major charging networks include Tesla's Supercharger network (which Mercedes vehicles can now access with an adapter), Electrify America, EVgo, and ChargePoint.
Charging availability varies widely by region. Urban and suburban areas typically have dense networks; rural areas may have sparse coverage. A 30-minute DC fast-charging stop every 200 miles is typical for highway driving, meaning a 500-mile trip takes roughly 8 to 9 hours including charging time — about 2 to 3 hours longer than a gas car.
Cold weather affects charging speed as well as range. In freezing temperatures, the battery warms itself before accepting a fast charge, which can add 10 to 15 minutes to a charging session. The EQS includes a pre-conditioning feature that warms the battery before you arrive at a charger, reducing this delay.
Frequently Asked Questions
How long does the battery last, and what happens when it degrades?
Mercedes warrants the battery for 8 years or 100,000 miles, covering defects and degradation beyond 70 percent of original capacity. Real-world data shows most EQS batteries retain 85 to 95 percent capacity at 100,000 miles. Battery replacement costs $15,000 to $20,000 out of warranty, though prices may drop as the market matures. Most owners keep their cars well before battery replacement becomes necessary.
Can I charge the EQS 450 at a Tesla Supercharger?
Yes, with an adapter. Mercedes vehicles now come with or can purchase a Tesla Supercharger adapter, allowing access to Tesla's network. Charging speeds are comparable to other DC fast chargers. You'll need to set up a separate Tesla account or use the Mercedes app to initiate charging.
What's the difference between the EQS 450 and the EQS 500?
The EQS 500 produces 516 horsepower versus the 450's 329, accelerates from zero to 60 in 4.1 seconds versus 5.5, and costs roughly $20,000 more. Both use the same battery and have similar range. The 500 is for buyers who prioritize acceleration; the 450 is the value option within the EQS lineup.
Does cold weather really cut range that much?
Yes. Cold reduces battery efficiency and increases cabin heating demand. Expect 20 to 40 percent range loss in freezing temperatures — a 260-mile car might deliver 150 to 200 miles. Pre-conditioning the battery and cabin while plugged in before driving helps, as does using seat heaters instead of cabin heat.
Is the EQS 450 worth the price compared to a Tesla Model S?
That depends on your priorities. The Tesla Model S costs less, offers more range, and accelerates faster. The EQS 450 offers a more luxurious interior, better build quality by most reviews, and Mercedes's service network. If you value range and value, the Model S wins. If you prioritize interior comfort and brand prestige, the EQS 450 justifies the premium.
