50 MPG combined is a figure most hybrid and even some electric vehicle owners would envy. That it’s achieved by the 2016 Hyundai Tucson Fuel Cell, a hydrogen-powered crossover, demonstrates the potential of alternative fuel technology, even if it comes with significant caveats. This isn’t a car for everyone, or even most people. The infrastructure limitations alone restrict its appeal to very specific areas, primarily Southern California. But for those early adopters committed to a zero-emission lifestyle and residing within reach of hydrogen fueling stations, the Tucson Fuel Cell presented a forward-thinking option.

City and highway performance

The EPA estimates almost identical fuel economy for city and highway driving: 49 MPG in the city and 51 MPG on the highway. This near-parity is typical of electric vehicles, as regenerative braking contributes more in stop-and-go traffic than it does at sustained highway speeds. In the Tucson Fuel Cell’s case, this suggests that urban dwellers, frequently starting and stopping, may see an MPG advantage. This is welcome performance for city dwellers.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,050 for the 2016 Hyundai Tucson Fuel Cell. This figure is based on driving 15,000 miles per year and assumes the national average cost of hydrogen fuel. Whether owners achieve this low cost depends heavily on where they live and the fluctuating price of hydrogen. Considering the premium placed on hydrogen fuel in California during this era, the early adopters of hydrogen technology likely experienced a higher cost per mile. Yet, it’s a benchmark showcasing the potential savings compared to gasoline-powered vehicles, given favorable circumstances.

Real-world expectations

While the EPA’s estimates provide a useful benchmark, real-world fuel economy for the Tucson Fuel Cell is heavily influenced by driving style and environmental factors. Aggressive acceleration and climate control use (especially air conditioning, which taxes the electrical system) can negatively impact efficiency. Conversely, gentle acceleration, judicious braking, and strategic use of regenerative braking can help maximize range and achieve closer to the stated MPG figures. Remember that hydrogen fuel stations are rare; it is important to be mindful of range to prevent running out of available energy.

How it compares

At the time, the Toyota Mirai, another hydrogen fuel cell vehicle, achieved a similar EPA rating of 66 MPG combined, making it seem more efficient on paper. However, its sedan body style didn’t offer the practicality of the Tucson’s crossover configuration. The Tesla Model S 70D, a contemporary electric vehicle, was rated at 101 MPGe combined, demonstrating the higher efficiency of battery electric vehicles. However, the Model S commanded a significantly higher price and didn’t address the hydrogen infrastructure challenge. The Toyota RAV4 Hybrid offered a combined 34 MPG, making it considerably less fuel efficient, but with the convenience of traditional gasoline refueling.

Tips to maximize efficiency

Anticipate traffic flow to maximize coasting and regenerative braking. The Tucson Fuel Cell features regenerative braking, which captures energy during deceleration and uses it to recharge the battery. Gentle, early braking allows the system to recover more energy.

Minimize aggressive acceleration and high speeds. Hard acceleration drains the fuel cell more quickly. Maintaining moderate speeds on the highway keeps you in the most efficient operating range. This strategy is also beneficial in extending the life and output capacity of the involved components.

Judiciously use climate control. The air conditioning system places a significant load on the electrical system. Pre-conditioning the cabin while the vehicle is plugged in, if possible, can reduce the initial energy demand when you start driving.

When compared with all Hyundai fuel economy data, you will see the Tucson Fuel Cell is competitive against other fuel-efficient offerings. The advantage is completely dependent on available hydrogen fuel infrastructure. While considering your vehicle purchase, please consult the TUCSON MPG across all years.
