103 MPGe combined makes the 2016 Tesla Model S 90D AWD an exceptionally efficient machine, though buyers aren’t necessarily drawn to it solely for that reason. The Model S 90D caters to those seeking high performance, advanced technology, and a luxury experience, all while minimizing their impact on lower fuel costs and running costs. It’s a statement car as much as it is a practical daily driver, and the electric powertrain is a core component of that overall appeal.

City and highway performance

The EPA estimates the Model S 90D achieves 101 MPGe in the city and 107 MPGe on the highway. This slight edge on the highway reflects the inherent efficiency of electric motors at steady speeds, where less energy is expended on acceleration. In typical driving, the Model S 90D smoothly blends city and highway environments, optimizing energy use via regenerative braking and efficient motor management. Spirited acceleration will always reduce range as peak power is used more frequently.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Tesla Model S 90D AWD at $750. This calculation is based on 15,000 miles of driving per year, using prevailing national average electricity prices. In reality, some owners may spend far less by charging overnight, and others may spend more if they frequently need to supercharge on the road. Even so, the $750 figure reveals the substantial savings possible when switching from gasoline to electricity, especially considering this is a large, powerful, all-wheel-drive vehicle.

Real-world expectations

While the EPA numbers provide a solid benchmark, real-world MPGe will vary depending on driving habits, ambient temperature, and terrain. Aggressive acceleration, frequent use of “Ludicrous Mode,” and consistently high speeds will all negatively impact range. Cold weather, including the use of the car’s defroster and heater, can also subtly reduce efficiency. Conversely, gentle acceleration, careful route planning using regenerative braking, and taking advantage of pre-conditioning features (heating or cooling the cabin while plugged in) can help approach or even exceed the EPA estimates.

How it compares

Compared to other luxury sedans of its era, the 2016 Model S 90D’s efficiency is far above the competition. Consider the 2016 BMW 750i xDrive, rated at just 19 MPG combined, or the Mercedes-Benz S550 4MATIC sedan, which achieves 20 MPG combined. Even hybrid luxury sedans like the 2016 Lexus LS 600h, which gets 20 MPG combined, cannot touch the Model S 90D’s efficiency. Buyers in this class prioritize performance and luxury, but the electric powertrain offers these attributes paired with an unrivaled “fuel” economy.

Tips to maximize efficiency

Careful use of regenerative braking significantly improves the Model S 90D’s overall MPGe. Learn to anticipate slowdowns and lift off the accelerator early, maximizing the energy recaptured by the system. Using “Low” regeneration makes it feel much more like ICE engine braking when lifting off the accelerator.

Preconditioning the cabin while the vehicle is plugged in can save a considerable amount of energy, especially in cold weather. By warming or cooling the interior before unplugging, the car can reduce the energy used for climate control during the initial part of your drive.

Monitor tire pressure regularly, as underinflated tires increase rolling resistance and decrease efficiency. Keeping tires at the recommended pressure ensures optimal performance and range.

Plan routes strategically using the Tesla navigation system, which can optimize energy consumption by considering terrain and traffic conditions. The navigation system provides accurate range predictions based on real-time data, allowing drivers to make informed decisions about charging stops.
