New 0.9 Turbo TwinAir - 105 HP
The new 105 HP 0.9 Turbo is the maximum evolution of the TwinAir family of engines that combine the concept of downsizing (reduction of displacement and weight) with sophisticated engineering such as supercharging through a turbocharger, the exhaust manifold integration in the cylinder head and the brand-new MultiAir 2 intake valve control system.
The second generation of MultiAir further optimises the engine's thermo-dynamic efficiency by modulating the amount of exhaust gases recirculated in the combustion chamber (internal EGR) thanks to a brand-new design of the intake cam profile.
The exhaust manifold in the cylinder head instead reduces the temperature of the exhaust gases (which are directly cooled by the engine cooling system).
This has a positive impact on fuel consumption because the enrichments otherwise necessary to keep down the maximum temperatures of the combustion gases are reduced in order to preserve correct turbocharger operation.
The small petrol engine with 2-cylinder architecture combined with a 6-speed manual gearbox develops 105 HP at 5,500 rpm with a maximum torque of 145 Nm at just 2,000 rpm.
The value of the specific power is considerable - a good 120 HP/litre - a value comparable to the sportier engines.
As on the previous Turbo TwinAir applications, ECO mode is also available for the new Fiat Panda TA 105: in this condition the maximum torque delivered is limited to 120 Nm and the power to 98 HP, allowing the power unit to function in the operating range which permits maximum efficiency and thus minimum emissions.
The TwinAir engine is a little gem also because of the good level of comfort it offers.
The agreeable and characteristic timbre of the two-cylinder engine has been optimised using the balancing countershaft and dual mass flywheel that minimise vibrations and shaking.
Particular attention was also paid to improving the soundproofing by studying containment solutions to reduce the levels of noise perceived in the passenger compartment and to improve the articulation index.
The Fiat Panda 105 HP 0.9 Turbo TwinAir is very brilliant in its performance (top speed of 186 km/h and it accelerates from 0 to 100 km/h in just 10.2 seconds) and it is at the top of its class in fuel consumption and emissions in the homologation combined cycle at the same time (4.6 litres/100 km and 109 g/km of CO2).
