The two-cylinder Twin-Air was unveiled earlier this year at the Geneva Auto Show, and will be used on 500 units of the automaker’s signature 500 minicar beginning in September. The choice to equip their trademark car with a new, superclean fuel engine is part of the company’s plan to increase emission reductions and remain one of the most eco-friendly carmakers in Europe, according to a statement made by brand head Lorenzo Sistino on Tuesday.

Sistino elaborated, “It has taken the car sector 15 years to cut CO2 emissions by 20 percent. With the new Twin-Air, the world’s most ecological fuel engine, Fiat will cut CO2 by a (further) 30 percent in one stroke.”

The Twin-Air uses improved technology to offer four-cylinder performance from a two-cylinder engine, and is just one more facet of the Italian auto company’s efforts to build and sell small, efficient, green cars that retain their brand’s style and flair.

“Twin-Air is another step ahead for eco-technology and can represent a giant leap for the environment,” Sistino said.
