The Hyundai Tucson Fuel-Cell Vehicle seemed awfully familiar when it rolled through the WardsAuto parking deck in early October for 2016 Wards 10 Best Engines evaluation.

That’s because it was the identical vehicle that so impressed us last year that we put it on the 2015 list. By all accounts, it’s the first time in 22 years of testing that the same vehicle arrived two years in a row. The only difference was a new license plate and updated promotional decals on the doors.

The telltale was the odometer, which reflected the CUV had been driven about 1,800 miles (2,897 km) after we returned it last October.

Hyundai keeps this Tucson FCV at its North American technical center in Superior Township northwest of Detroit, driven primarily by test engineers.

The South Korean automaker is doing its darndest to kickstart the market for hydrogen-powered fuel-cell vehicles, and ground zero is the state of California, where the Air Resources Board is pushing heavily for zero-emission tailpipes. The Tucson FCV emits nothing but water.

Despite regulatory motivation, the market remains minuscule, barely worth tracking.

Last year, when Hyundai began leasing the Tucson FCV in California for three years for $499 a month and $2,999 down, the automaker found a mere 60 customers who lived close enough to a handful of hydrogen-fueling stations near Sacramento, San Francisco and Los Angeles.

Today, the customer pool has grown incrementally to 82 (plus 10 north of the border in Vancouver), and those numbers should hold steady through 2016, says Hyundai spokesman Derek Joyce.

The limited infrastructure is holding back broader acceptance of fuel-cell vehicles. Joyce says there are lots of people in California who want the Tucson FCV, partly because fuel and maintenance are everyone’s favorite price – free.

But the 82 customers were picked after a fair amount of vetting. Hyundai reviewed each customer’s driving patterns – where they live, work and play – to make sure the limited infrastructure would meet their needs.
