The Italian automaker decided to expand the powertrain options available on the Alfa Romeo Giulietta with a second generation MultiJet diesel engine.
This 2.0 JTDM-2 is able to generate 140 bhp and 350 Nm of torque @ 1750 rpm, and the automaker says it features the ‘most technologically
advanced solution for controlling high injection pressures’.
Accelerating from nought to 62 mph (0 to 100 Km/h) in the Alfa Giulietta 2.0 JTDM-2 140 bhp takes 9 seconds, and the 5-door hatchback is able to reach a maximum speed of 127 mph. Co2 emissions levels are 119 grams per Km, while consumption figures indicate that the car can return 62.8 mpg in a combined cycle (UK rating).
The Alfa Giulietta 2.0 JTDM-2 price starts at 20,750 GBP for the Lusso version, while the Veloce model starts at 22,050 GBP. 
Alfa Romeo press release :
The sporty Alfa Giulietta five-door hatchback range has just been
boosted by the addition of another ultra frugal yet high performing
second generation MultiJet diesel engine.
The new 2.0 JTDM-2 140 bhp is
an ideal engine for both company car drivers and private owners
requiring low fuel consumption and low running costs combined with
driving comfort for long trips.
The new engine is equipped with the latest generation JTDM-2 MultiJet Common Rail system that is already present on the 1.6 JTDM-2 (105 bhp) and the 2.0 JTDM-2
(170 bhp) power units. The system represents the most technologically
advanced solution for controlling high injection pressures (around 1600
bar) independently of engine RPM and quantity of fuel injected.
Advanced engine management guarantees particularly smooth engine operation in all situations.
This technology, combined with an electronically controlled variable
geometry turbocharger, guarantees excellent torque delivery: 350 Nm at
just 1750 rpm (with the D.N.A. selector in Dynamic position) and 320 Nm
at 1500 rpm (in Normal) – giving it the highest torque in its class
compared to similarly efficient and powerful engines.
This new Alfa Romeo Giulietta features reduced CO2
emissions and reduced fuel consumption (119 g/km and 62.8 mpg
respectively in the combined cycle), a top speed of 127 mph and
acceleration from 0 – 62 mph in 9 seconds. The engine is designed for
customers who appreciate excellent throttle response but are also
concerned with fuel consumption and running costs. In real terms, with a
13% BIK (Benefit in Kind) rate, 40% tax bracket company car drivers
will pay as little as £90 a month in company car tax for the Lusso trim
On the theme of environmental respect, the engine is Euro 5 compliant
and is equipped with DPF (Diesel Particulate Filter) and Start&Stop
as standard. Moreover, advanced exhaust gas treatment technologies have
been used, 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.
Lastly, the 2.0 JTDM-2 140 bhp
boasts a particularly long servicing interval, thus minimising work
required on the vehicle during its life cycle and cutting its running
costs. The fact that the car only needs servicing every 21,000 miles is a
testament to the high quality levels achieved and the efforts made to
improve durability and efficiency even further, by means of careful work
on individual components.
