than a 4-cylinder having the same performance characteristics, this new engine offers a significant reduction
in CO2 emissions and its first application was on the Fiat 500 and Fiat 500C. The TwinAir family was further
developed to include application of the turbo version on other A and B-segment models produced by Fiat
Group Automobiles.
Development also continued on a naturally-aspirated version, which will feature the second generation of the
electro-hydraulic valve management system, the MultiAir II. A CNG turbo application is also being developed
for the TwinAir family. The MultiAir II technology is also being developed for application on 16v Fire engines
and will offer reduced CO2 emissions without compromising performance.
Work also continued on the TwinAir and Fire engine families to further reduce consumption and emissions to
meet the new Euro 5+ and Euro 6 standards.
For the 8v Fire family, production began on the new Fire 1.0 Low Friction and 1.4 Evo2 Flexfuel in Latin
America.
Application of the Start&Stop system on all Fire family engines was completed and the new CNG/gasoline
1.4 16v Fire Turbo was launched on the new Doblò. Development of Euro 5 LPG versions of the 1.2 8v,
1.4 8v and 1.4 16v (naturally-aspirated and turbo) Fire engines was completed and production launch is
scheduled for 2011.
In March, the 1.8 235 hp direct injection turbo (the second engine in the B family) went into production for
application on the Alfa Romeo Giulietta. Further enhancements were also made to this engine family’s injection
and combustion system to achieve Euro 6 emissions levels.
For diesel engines, Fiat Powertrain began supplying Fiat Group Automobiles with a new version of the
eco-efficient 85 hp 1.3 Small Diesel Engine. The use of a new high-efficiency turbo-compressor with the
introduction of Injection Rate Shaping on the MultiJet II injection system, has enabled the Punto Evo to achieve
CO2 emissions of 95 g/km in combined cycle.
2010 also saw the production launch of the new 140 hp 2.0 B Family engine with downspeeding technology,
designed to offer reduced consumption and improved responsiveness at low RPMs for application on the
Alfa Romeo Giulietta. The adoption of a high-efficiency turbo-compressor and new engine input reduction
technology has enabled a 4% reduction in consumption in combined cycle.
Work also continued on development of the 2.0 B Family engines with MultiJet II injection system, due to go
into production in early 2011 on the Fiat Freemont (170 hp version) and the Fiat Ducato (115 hp version).
In the area of transmission technology, one of the most significant developments during the year was
application of the automatic dry dual clutch C635 TCT (Twin Clutch Technology) on the Alfa Romeo Giulietta.
Already available on the Alfa MiTo, during 2011 it will also be launched on the Giulietta (170 hp 1.4 MultiAir
and 170 hp 2.0 MultiJet) and a Chrysler passenger car.
Numerous automated transmission applications were developed during 2010 including the robotized C514
MTA transmission for the Fiat 500 with TwinAir, which has brought CO2 emissions down to 92 g/km: the best
performance achieved to date in the A segment.
