The 2024 Mercedes-Benz EQS 450 4matic’s 95 MPG combined isn’t just about saving money on gas. It means quietly driving through cities and highways in luxury, without constantly worrying about range as much as other EV owners do. This electric flagship sedan suits drivers who value refinement and cutting-edge technology, and who appreciate the almost invisible impact on the environment that comes with a carefully engineered EV.

City and highway performance

The EQS 450 4matic performs well in both city and highway environments, as shown by its EPA ratings of 93 MPG in the city and 98 MPG on the highway. Electric vehicles often perform well in stop-and-go traffic due to regenerative braking. This captures energy when the car slows down. On the highway, the EQS’s aerodynamic shape helps it cut through the air, increasing its efficiency at higher speeds. The 4matic all-wheel-drive system provides added traction and stability in all weather conditions for buyers in northern climates who need confidence regardless of road conditions. The instant torque from the electric powertrain makes merging and passing easy for a smooth driving experience.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz EQS 450 4matic to be $800. This is based on driving 15,000 miles per year using both city and highway driving, and taking into account national average electricity prices. Individual electricity costs will vary based on location and charging habits (home vs. public charging), but the $800 is a useful benchmark for comparing the EQS’s costs to those of gas-powered luxury sedans. Drivers who drive a lot of miles could save even more money.

Real-world expectations

The EPA ratings provide a standard for comparison, but real-world fuel economy can change based on driving style, temperature, and terrain. Quick acceleration and hard braking can reduce range. Consistently driving at high speeds on the highway also impacts efficiency and cold temperatures can reduce battery capacity, decreasing overall range. The EQS 450 4matic includes a thermal management system to optimize battery performance. Experienced EV drivers can often exceed the EPA estimates by adopting efficient driving habits and using the vehicle’s regenerative braking. The EQS also features drive modes that prioritize performance or efficiency, allowing drivers to customize the vehicle’s behavior.

How it compares

The EQS 450 4matic has strong competition in the luxury electric sedan market. The BMW i7 xDrive60 achieves a combined MPG equivalent of 87, marking the EQS as more efficient. The Tesla Model S Long Range achieves 120 MPGe combined, but has a different driving experience and interior. The Lucid Air Grand Touring, with its 137 MPGe combined, is very efficient but costs more and doesn’t have as established a brand. For the buyer considering the EQS, the slight difference in MPGe with the Model S isn’t the only thing they’re thinking about. They are considering brand prestige, interior, and the Mercedes-Benz ownership experience, and are willing to accept the EQS’s efficiency numbers for these reasons.

Tips to maximize efficiency

Use the regenerative braking system well. The EQS offers adjustable levels of regeneration, allowing you to control how much the vehicle slows down when you lift the accelerator. Find the setting that suits your driving style. Maximizing regenerative braking recovers energy that would be lost as heat, extending your range and improving efficiency.

Precondition the battery and cabin before driving. On cold days, warming up the battery and cabin while the vehicle is plugged in can reduce the energy needed to heat the vehicle once you start driving which prevents range drops, especially during short trips.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and ensure it is at the recommended level, which can be found on the driver’s side doorjamb. Even a slight increase in tire pressure can make a difference.

Use the ECO drive mode. The EQS offers drive modes that optimize vehicle performance. The ECO mode prioritizes efficiency by limiting power output and adjusting the climate control system to use less energy. When range is a concern, the ECO mode is a good choice.

Reduce aerodynamic drag. Roof racks and other accessories can increase aerodynamic drag, reducing efficiency. Remove unnecessary items from the roof of your vehicle and ensure that accessories are properly installed.
