The new 500X has been presented to the international press in the fascinating location of the National Museum of Cinema, which has been hosted in the Mole Antonelliana in Turin since the year 2000. That it is a very special event is confirmed by the “New 500X” logo projected in the evening on the monument that has been dominating the city skylight for over a century: a tangible sign of the true bond between Turin, the Fiat brand and great cinema.
During the event, Luca Napolitano, Head of EMEA Fiat and Abarth Brand, announced the official name of the new FireFly engine family and of the two new engines – FireFly Turbo 1.0 and FireFly Turbo 1.3. Introduced for the first time on a Fiat model, the two efficient and innovative engines are yet another confirmation of the engineering supremacy of the Group. Not unlike their namesake, the new FireFly Turbo engines are the most compact and cleanest power source currently fitted on Fiat cars.
Next-generation FireFly engines for performance at the top of its category
The New 500X is the first Fiat model to fit the innovative family of FireFly Turbo engines designed to strike the right balance for customers between the driving performance and satisfaction of the best turbo diesel engines (while being 20% quieter) and ensuring 20% better fuel efficiency compared to the previous petrol engines.
Euro 6/D-TEMP compliant and fitted with Gasoline Particle Filter (GPF), the new FireFly Turbo engines are the result of over 75,000 hours of virtual tests, 60,000 hours of real-life off-vehicle tests and 5 million kilometres clocked up on roads worldwide to confirm their robustness and reliability.
Developed on a modular structure with 0.33 litre cylinder unit, the new FireFly Turbo 1.0 and 1.3 engine line-up includes a three-cylinder 1-litre powerplant that delivers 120 HP and 190 Nm of peak torque paired with a six-speed manual transmission and front-wheel drive and a four-cylinder 1.3-litre engine with 150 HP and 270 Nm of torque, in this case combined with six-speed DCT dual clutch automatic transmission and front-wheel drive.
Their specific architecture guarantees efficiency, modularity, a high degree of component and production process standardisation, flexibility and openness to future evolutions.
The new engines are made entirely from aluminium alloy, ensuring unbeatable lightness (the three-cylinder version weighs just 93 kg), while the cylinder block, developed in partnership with Teksid, is in high-pressure die-cast aluminium alloy, with a bedplate architecture for the best combination of ride, weight and structural performance.
The use of many innovative technical characteristics contribute to improving performance and maximising driving comfort, such as direct fuel injection to maximise volumetric efficiency and the low inertia turbocharger controlled by an electrically operated wastegate actuator which, combined with a supercharger module water-cooled directly in the intake manifold, ensures a faster transient response and very swift acceleration.
Another innovation feature in the new FireFly Turbo engines is the introduction of the third generation of the exclusive MultiAir technology (called MultiAir III), which further optimises combustion efficiency through continual control of intake valve opening and timing: thanks to the specific intake and exhaust cam profiles, this improves low load efficiency by recycling exhaust gas through advance opening of the intake valves. When higher power is required, the MultiAir III technology reduces the real compression ratio by delaying valve closure, controlling knock and substantially improving fuel efficiency even at the highest loads.
Last but not least, the new 500X range of petrol engines is completed by the reliable 110 HP 1.6 E-Torq, combined with manual transmission and front-wheel drive, now upgraded to meet the Euro 6/D-TEMP pollution reduction standard.
