It is no longer a rumor that Fiat is building a four-door version of the 500, called the 500L. The 500L will debut at the Geneva Motor Show on March 6. The 'L' in the name stands for large, according to Fiat. It will join the cabrio, Abarth and standard car in the 500 range. 

Fiat says that 500L will blends the B- and C-segments by offering MPV passenger room in a small car. The car is 414 cm long, 178 cm wide and 166 cm high. That makes it nearly 60cm longer and 20cm taller than a standard 500. 

Fiat will put the 500L on sale in the last quarter of 2012 with the Twinair, 1.4 liter petrol and 1.3 liter diesel as engine options, and it will be built in Kragujevac, Serbia.
