Alfa Romeo has
launched the next-generation 1.3 Multijet engine
with 95 bhp and 200 Nm on the MiTo, just weeks
after it was premiered and commercialised for
the first time on the Alfa Romeo hatchback's
sister model, the Fiat Punto Evo. It also comes
less than a week after the MiTo range was extended with an
LPG version.
Fiat
Powertrain's award-winning 1.3 Multijet engine takes on the
'JTDM' name when fitted to an Alfa Romeo and the new MiTo
1.3 JTDM
is now available
for ordering on the Italian market in two specification
levels, "Progression" and "Distinctive", with the list price
respectively being 17,600 euros and 19,200 euros, and with
the possibility of personalising the "Distinctive" level
further with the two customisation packs that are available
to the range (Sport or Premium); in both cases the price of
the car once they are fitted is 20,100 euros.
Fiat
Powertrain's 1.3 Multijet (JTDM-2) engine range is now equipped with the
next-generation Common Rail injection system. It launched in
the Punto Evo at the Frankfurt IAA last month and now is
added to the Alfa MiTo which shares the same underpinnings
as the B-segment Fiat model. This
highly advanced solution can control high engine pressures
(up to 1600 bar) without being tied to engine speed or the
quantity of fuel injected. In the 1.3 JTDM-2 the system uses innovative common rail injectors
that, thanks to a balanced hydraulic servo-valve, are able
to more precisely control the quantity of diesel injected
into the combustion chamber, with a faster and more flexible
sequence of injections than was previously possible. By
reducing the amount of time between injections, these
injectors optimise fuel introduction to the chamber and
therefore make the diesel combustion process more gradual,
with positive effects for consumption, emissions, NVH and
handling. In fact, the new common rail injector cuts consumption and CO2 on the approved cycle by
around 2%, while at the same time reducing harmful
emissions. The second-generation MultiJets are therefore the
latest development in the Common Rail injection system
which, after the JTD (1997) and MultiJet (2003) engines,
gives the Fiat Group yet another first in this field.
The 1.3 JTDM-2 is available in the Alfa MiTo in Euro 5
specification with 95 hp and features a particulate filter.
The engine boasts a next-generation variable geometry turbocharger that,
combined with the new second-generation 'Multijet' injection
system, ensure the best possible turbo function at any
engine operating level.
The performance levels of the 95 bhp second-generation 1.3
JTDM-2 (Euro 5) is slightly higher in the MiTo than that
fitted to the Punto Evo, due to Alfa Romeo's more sporty
brand characteristics. Torque is 180 Nm at 1,500 rpm in
'Normal' mode or 200 Nm at the same revs when the 'Sport'
option is selected. The MiTo 1.3 JTDM reaches a top speed of
180
km/h (2 km/h higher than the equivalent Punto Evo model), 0
to 100 km/h is achieved in 11.6 seconds (0.1 seconds quicker
than the Punto Evo) while combined cycle fuel consumption is 4.3 l/100
km (4.2 l/100 km for the Punto Evo) and there is just 112 g/km of CO2 emissions in the combined cycle
(compared to 110 g/km for the Punto Evo).
The new MiTo 1.3 JTDM-2 also benefits from Fiat's fuel-saving
Start&Stop system and Gear Shift Indicator, as this
cutting-edge technology is being quickly rolled out across
the Fiat Group Automobiles' ranges. As well as being fitted
to the Fiat 500 it is now available on the Punto Evo, and
specifically on the very similar second-generation 1.3
Multijet 95 bhp application. Start&Stop temporarily switches
off the engine and restarts it in order to reduce fuel
consumption and noise levels. In these situations, which are
typical of heavy traffic in urban areas and when stopped at
traffic lights, when the control strategy permits, the
system automatically cuts out the engine in order to reduce
fuel consumption and emissions by up to 15% for an urban
route and 3.5% over an NEDC-type cycle. The Gear Shift Indicator (GSI)
linked to the Start&Stop system is a kind of co-pilot that
discreetly advises drivers when they should change gear,
leading to a more fuel-efficient use of the engine. For
example, the GSI may suggest shifting to a higher gear, by
means of a signal on the instrument panel, in order to allow
the engine to combust a leaner mixture, i.e. containing less
fuel, or changing down a gear to make best use of the
available torque.
