The Multi-Purpose Wagon is nine inches longer than the regular 500L.

Following months of rumors and speculation, Fiat has published the first official images of the 500L Multi-Purpose Wagon (MPW), a more spacious version of the existing 500L that can be ordered with up to seven seats.

Based on Fiat's Small-Wide platform, the 500L MPW stretches 171 inches long, 70 inches wide and 65 inches tall, dimensions that make it nine inches longer and about a third of an inch taller than the 500L. The two vehicles look nearly identical from all angles because they share numerous body panels, but the MPW has a noticeably longer rear overhang.

The MPW can be fitted with a third row of seats that enables it to carry up to seven passengers, though the rear seats are probably best left to small children. Alternatively, the van can be ordered with just five seats and a generously-sized trunk. All versions are available with leather upholstery, dual sunroofs, a touch screen-based infotainment system and a rear-view camera.

The palette of engines for European-spec models includes a 95-horsepower 1.4-liter four-banger, a 105-horsepower 0.9-liter two-cylinder borrowed from the Alfa Romeo MiTo and two turbodiesel units that churn out 85 and 105 ponies, respectively. All engines send power to the front wheels only, though all-wheel drive is a possibility further down the road.

Like the regular 500L, the MPW will be built in a Kragujevac, Serbia, in a ex-Zastava factory that assembled the infamous Yugo during the 1980s.

More details about the 500L MPW will be available next month as the 500 family celebrates its sixth year on the market. The seven-seater people mover will land in U.S. showrooms early next year at the very latest.
