10 Most Fuel-Efficient Luxury Cars (2016)

Whether you’re looking for the maximum efficiency of an all-electric vehicle, the added range and flexibility of a hybrid, or the performance advantages of diesel power, there’s a luxury vehicle with your name on it. Here are the 10 most fuel-efficient luxury vehicles of the 2016 model year, based on each model’s highest EPA city/highway combined fuel economy rating.

The diesel-powered version of BMW's iconic 3 Series provides fans of sports sedans with an alluring combination of 45 highway mpg and 280 lb-ft of torque. Unencumbered by a big battery pack, the 3 Series diesel boasts lower mass and greater cargo flexibility than similarly sized hybrid and electric vehicles.

City/highway/combined mpg: 32/42/36

The Lexus ES is known for its reliability, refinement and comfort. Opting for the hybrid version adds impressive fuel economy of 40 mpg combined, and a range of nearly 700 miles -- enough to get you from New York City to Louisville, Kentucky, without having to stop at a gas station (for gas, anyway).

City/highway/combined mpg: 40/39/40

The 2016 Lincoln MKZ Hybrid features the same starting sticker price as its gas-only counterpart ($36,085, with destination), making it the most affordable sedan on this list.

City/highway/combined mpg: 41/39/40

Underneath the Lexus CT 200h's sporty styling lies the world’s most proven hybrid powertrain, the same one found in the previous-generation Toyota Prius. With a starting sticker price of $32,200, the most affordable Lexus is also the most affordable vehicle on this list.

City/highway/combined mpg: 43/40/42

With a 0-60 mph time of 4.2 seconds and the ability to drive 15 miles on electricity alone, BMW's i8 is the supercar of the future. And it has the looks to match.

First 15 miles: 76 mpge* combined
Next 315 miles: 28 mpg combined

*mpge = miles per gallon equivalent

Combining the efficiency and flexibility of a plug-in hybrid with Audi style and hatchback practicality, the A3 Sportback e-tron offers multifaceted appeal.

First 16 miles: 83 mpge combined
Next 364 miles: 35 mpg combined

The all-electric B250e offers a mix of Mercedes-level luxury, hatchback versatility and combined city/highway efficiency of 84 mpge.

City/highway/combined mpge: 85/82/84
Range: 87 miles


Tesla’s new Model X is the most fuel-efficient SUV money can buy, luxury or otherwise. It starts at more than $80,000, but combines three-row utility with efficiency equivalent to 93 mpg and 238 miles of per-charge range.

City/highway/combined mpge: 91/95/93
Range: 238 miles

With features like an all-glass panoramic roof, soft Nappa leather and a massive 17-inch touchscreen, it’s clear the Model S is no ordinary electric car. Opting for the 75 kWh range upgrade makes it the most efficient version in the lineup, and it’s still able to sprint to 60 mph in 5.2 seconds on its way to a top speed of 130 mph.

City/highway/combined mpge: 102/105/103
Range: 259 miles

Topping this list for the third year in a row, the BMW i3 isn’t just the most energy-efficient luxury car, it’s the most efficient vehicle, period. Buyers with range concerns can add a range-extending gas engine, while those motivated by environmental concerns will feel warm and fuzzy knowing the i3 is manufactured in a plant powered completely by four windmills.

City/highway/combined mpge: 137/111/124
Range: 81 miles
