The Fiat Panda is a substantial car that boasts cutting-edge engines in terms of both performance and fuel consumption and emissions. Combined with 5-speed gearboxes, standing out amongst the engines in the range are the brand new twin-cylinders with Start&Stop system supplied standard: the 85 HP 0.9 TwinAir Turbo, named "International Engine of the Year 2011", and the 65 HP 0.9 aspirated TwinAir, being fitted for the first time (not sold in Italy). The renewed 69 HP 1.2 Fire petrol engine and the 75 HP 1.3 Multijet II, with Start&Stop supplied standard, complete the range of engines.
Later the new Fiat Panda range will be expanded with the Dualogic automatic robotized transmission combined with the TwinAir engine, the 80 HP 0.9 TwinAir Turbo Natural Power (petrol/methane) and 69 HP 1.2 EasyPower (petrol/LPG) bifuel engines that attest to the constant attention Fiat Automobiles pays to the environmental topics through its research and development of immediately accessible solutions.
85 HP 0.9 TwinAir Turbo
First of a new family of two-cylinder engines developed by Fiat Powertrain, this 0.9 TwinAir Turbo engine develops 85 HP (63 kW) at 5500 rpm of full power and a torque of 145 Nm at 1900 rpm (constant up to 3000 rpm). Moreover, if you prefer to prioritise the green aspect and lower fuel consumption, you can press the ECO key on the dashboard to limit torque to 100 Nm at 2000 rpm. This engine records 4.2 litres/100 km and CO2 emission equal to 99 g/km in the combined cycle.
A real jewel of engine design, the brilliant two-cylinder employs the revolutionary MultiAir technology developed and patented by Fiat Powertrain which was introduced in 2009. The heart of MultiAir is a new electro-hydraulic valve management system that reduces fuel consumption by controlling air directly via the inlet valves (without using the throttle). MultiAir reduces polluting emissions (thanks to its improved combustion control) and also considerably improves performance by boosting driveability. Indeed, compared to a traditional petrol engine of equal displacement, MultiAir engines guarantee an increase in power (up to 10%) and torque (up to 15%) in addition to a significant reduction in emissions of CO2 (up to 10%).
Elected "International Engine of the Year 2011", the new TwinAir engine also takes the concept of downsizing to an extreme: by combining a small-sized engine with a next-generation turbocharger performance comparable to - or even better than - that of a larger engine is obtained but with less fuel consumption and lower emissions. Not only that, the turbo significantly increases the maximum torque, making it available at a very low rpm, with the result of offering greater flexibility and an unrivalled responsiveness compared to conventional aspirated engines. All this comes with a simple build to the benefit of strength and reliability.
The new engine has undergone a number of unit displacement optimisation and tuning interventions in terms of thermo-dynamic efficiency and fluid dynamic configuration.
Finally, special attention has been placed on the NVH (noise, vibration, and harshness) aspect to ensure vibration performance with a characteristic sound. For this purpose, a balancing countershaft was used to maintain optimal vibration levels in all operating conditions of the engine, from idling speed to top power.
65 HP 0.9 aspirated TwinAir
The new Panda is the first Fiat Group Automobiles car to make its world debut in the "aspirated" version of the TwinAir engine that delivers maximum power of 65 HP (48 kW) at 6250 rpm and a torque of 88 Nm at 3500 rpm. All with a reduction in fuel consumption and CO2 emissions - the values recorded in the combined cycle are 4.2 l/100 km and 99 g/km, respectively - and with performance comparable to engines of the same power.
One peculiarity of the new engine is the introduction of the second-generation MultiAir system that sets its sights on the goal of maximising combustion efficiency. This is thanks to an innovative profile of the intake cam bush and a new way to manage the valves, called "hybrid". In detail, the new intake profile makes a pre-lift of the intake valve possible during the exhaust phase. In this way a part of the exhaust gases can flow into the intake duct to be re-aspirated during the following intake phase. In this way the so-called internal recirculation of exhaust gases (Internal EGR) is achieved, which further optimises combustion efficiency and therefore reduces fuel consumption. With the high degree of flexibility that distinguishes the MultiAir system, this new adjustment of the valves (called hybrid) can obviously be activated only where it is needed, and furthermore the amount of recirculated internal EGR can be totally modulated.
69 HP 1.2 Fire EVO II
The 69 HP 1.2 EVO II is the latest evolution of the FIRE family that boasts over 10 million units produced. Thanks to the continuous updates and its flexible architecture, this family of engines remains a point of reference in the category as use of the continuously variable valve timing unit shows, able as it is to optimize valve timing (opening and closing) at all engine speeds. In this way fuel consumption and CO2 emissions on the one hand are reduced (5.2 litres/100 km and 120 g/km, respectively); on the other, performance increases to ensure torque availability at low rpm (102 Nm at 3000 g/min) and power at high rpm (69 HP at 5500 g/min).
75 HP 1.3 Multijet II
With a view to respect for the environment coupled with driving satisfaction, the new Fiat Panda offers the 1.3 MultiJet II (Euro5) with DPF standard, which delivers a maximum output of 75 HP (55 kW) at 4000 rpm and a torque of 190 Nm at just 1500 rpm.
A masterpiece of technology in miniature - complete with all of its accessories, it weighs about 140 kg - the new turbodiesel is small in size: less than 60 cm long and less than 70 cm high, it boasts a component layout designed to take up less room. The compact and technologically sophisticated 1.3 Multijet II is also capable of outstanding performance.
Equipped with fixed geometry turbocharger with intercooler optimised for delivering torque at low speed, the 1.3 Multijet II records just 104 g/m of CO2 emissions and fuel consumption equal to 3.9 litres per 100 km in the combined cycle.
Belonging to the second generation of Multijet engines, this engine ensures economy, ecology and performance levels found nowhere else on the market. In contrast to the first generation of MultiJet engines, the fuel supply system is now equipped with faster injectors able to execute multiple injections in rapid succession. Specifically, the system can now perform a main modulated injection of fuel in several distinct phases and anticipate the ones that follow. The servo valve with balanced plunger of the MultiJet II system enables it to manage up to 8 injections per cycle, offering greater speed, flexibility and precision in the various phases of operation. The injector is also simpler and more reliable because its construction is less complex and it has 40% less components.
Thanks to the new type of injector, now strategies focused on optimizing the increasingly advanced combustion can be achieved, such as the Rate Shaping injection that involves two consecutive injections so close together in time as to generate a continuous and modulated profile of the fuel supply into the cylinders. With this method the combustion process is improved, all to the benefit of quieter operation and particulate and nitrogen oxide (NOx) emissions. Today the Multijet II engines totally satisfy the Euro 5 standard and at the same time mark a decisive step toward stricter regulatory levels in the future.
Lastly, again in full respect for the environment, advanced exhaust gas treatment technologies have been used for the 75 HP 1.3 Multijet II, namely a Close Coupled Diesel Particulate Filter and a built-in EGR (Exhaust Gas Recirculation) system that improves control of temperature and gas flow, simultaneously guaranteeing lower emissions and reduced fuel consumption.
