For small displacement gasoline engines, the most significant area of activity was continued development of
the new two-cylinder TwinAir family, following production launch of the turbocharged 85 hp version equipped
with the revolutionary MultiAir system combined with a fluid dynamic configuration specifically designed to
achieve maximum combustion efficiency. Smaller and lighter than 3- and 4-cylinder engines with the same
performance characteristics, this new engine offers a significant reduction in CO2 emissions. Initially launched
on the Fiat 500 and 500C, it is now also available on the Lancia Ypsilon and a turbo version is already in
development for application on the new Fiat Panda (A segment), as well as the Fiat Punto and Alfa Romeo MiTo
(B segment). There are also plans for introduction of a variable displacement oil pump on the TwinAir in the first
half of 2012, on the 105 hp version that will provide improvements in consumption and emissions.
Production of a naturally-aspirated version also began, representing first application of the second generation
MultiAir II valve management system on this type of engine. Launch is planned for 2012 on the new Fiat Panda.
A turbo CNG version is also in development.
MultiAir II technology will also be applied to 16v versions of the FIRE family, providing further reductions in CO2
emissions with no loss in performance.
Production levels for the FIRE 1.0 Low Friction and 1.4 Evo2 Flexfuel (both 8v versions) in Latin America remained
strong.
During the first quarter of 2011, the company completed modifications to the bifuel LPG versions of the FIRE
family of engines, bringing them in line with the Euro 5 standard. The 1.2 version was launched on the Fiat
Panda; the 1.4 8v on the Fiat Punto, the Lancia Musa and Ypsilon; and, the 1.4 16v version debuted on the Fiat
Bravo. Production continued on the Euro 5-compliant 1.4 16v turbo bifuel (CNG/gasoline) version of the FIRE
for the new Doblò and a Euro 6-compliant version is in development.
Enhancements are being made to the injection and combustion system of the 235 hp 1.8 direct injection turbo
version, currently available on the Alfa Romeo Giulietta, to bring the engine in line with Euro 6 standards and
further increase its already excellent performance specifications.
For diesel engines, the eco-efficient 85 hp 1.3 MultiJet was launched on the Punto Evo with variable geometry
turbocompressor, which offers the perfect mix between performance and emissions (90 g/km of CO2 combined
cycle). In addition, introduction of an intelligent alternator and variable displacement oil pump are also planned.
The 95 hp version of the 1.3 MultiJet with variable geometry turbocompressor was launched on the new Ypsilon.
The 2.0 MultiJet was launched on the Fiat Ducato (115 hp) and the Fiat Freemont (140 and 170 hp). Application
on the Freemont represents one of the first results of integration of the Fiat and Chrysler portfolios.
Euro 5+ and Euro 6 diesel engines are also in the advanced stages of development.
In the transmissions area, the C635 Twin Clutch Technology (TCT) automatic transmission, already available
on the Alfa Romeo MiTo, was introduced on the 170 hp 1.4 MultiAir and 170 hp 2.0 MultiJet versions of the Alfa
Romeo Giulietta.
A version of the C514 transmission has also been developed for use with the 8V FIRE. Application is planned on
the Fiat Panda and new Lancia Ypsilon in 2012.
