The Nissan Leaf is not only the world's best-selling electric car, but also probably the world's most popular electric taxi.
Leaf taxis operate in several European countries, enduring the same demanding conditions as gasoline, diesel, and hybrid cabs.
One of those countries is Spain, and it's about to get a whole lot more Leaf taxis.

At the 2016 Madrid Motor Show, Nissan and taxi company Ciudad del Taxi announced an order of 110 Leaf taxis for service in the Spanish capital.
This is the largest fleet order for electric taxis so far, according to Nissan.
It will also put Madrid in contention with Amsterdam—which has around 100 Leaf taxis in operation—for the world's largest fleet of the vehicles.
All of the Leafs in the Madrid order have the larger 30-kilowatt-hour battery pack that was introduced for the 2016 model year.
Spain is already one of the largest markets for Nissan electric taxis, along with The Netherlands and the U.K.
In addition to the Leaf, Nissan sells a taxi version of the e-NV200 electric van.

That model is actually built in Spain, at Nissan's Barcelona plant.
The internal-combustion version of the e-NV200—just called NV200—is New York City's standardized taxi.
Nissan has demonstrated Leaf taxis in the U.S. before, but there has been no large-scale attempt to deploy them here.
New York studied electrification under the administration of previous mayor Michael Bloomberg, but the effort seems to have lost traction under current mayor Bill De Blasio.
Elsewhere, Nissan claims to have sold more than 800 Leaf and e-NV200 taxis, most of which operate in Europe.
In Canada, a Montreal taxi company has also discussed adding a fleet of electric cars.
Taxi Hochelaga said last year that it would deploy 2,000 electric taxis in Montreal by 2019.
If owners follow through with those plans, that would likely give the Canadian city the world's largest electric-taxi fleet.
Given its popularity elsewhere, it wouldn't be surprising with the Leaf made up a large portion of that fleet.
