A WIDE RANGE OF ADVANCED TECHNOLOGY POWERPLANTS
C4 is available with a diversified engine range from launch. The
offering is organised around five petrol engines, including the new 143
bhp 2.0i recently introduced on the C5, and three HDi diesel engines
developed through the cooperation project with Ford. They include the
HDi 92 – fitted for the first time on a PSA Peugeot CitroŽn vehicle –
and the new HDi 110 and HDi 138 recently introduced in the CitroŽn
FIVE PETROL ENGINES FROM LAUNCH
petrol engines are available: the 1.4i 16V (90 bhp DIN), the 1.6i 16V
(110 bhp DIN), the 2.0i 16V (138 bhp DIN), the new 2.0i 16V (143 bhp
DIN) recently introduced on the C5 and available with the C4 Saloon,
and the 2.0i 16V (180 bhp DIN), installed on a CitroŽn vehicle – the C4
Coupť – for the first time. All the engines feature a cylinder head
with a double overhead camshaft, four valves per cylinder and a
motor-driven throttle, controlled electrically by the engine control
unit. All the engines are equipped with a five-speed manual gearbox,
except for the 143 bhp 2.0i 16V engine, which is coupled with an
automatic gearbox. The 110 bhp 1.6i 16V engine is also available with
an automatic gearbox.
The 1.4i 16V engine is the
entry-level model. It develops 65 kW EEC (90 bhp DIN) at 5,250 rpm and
maximum torque of 133 Nm at 3,250 rpm. It features continuously
variable valve timing (VVT) to optimise filling of the combustion
chambers at all engine speeds. Variable valve timing offers more torque
at low engine speeds. Torque of 118 Nm – 90% of maximum torque – is
available from 1,800 rpm, thus contributing to the respect of the Euro
IV emission standard. The angular variation with respect to crankshaft
timing is managed by the engine control unit, in line with the engine
oil temperature, engine load and speed.
This engine also
features a stiffened cylinder block to meet high standards of acoustic
comfort. Fuel consumption is low (6.4 l/100 km over a standard combined
cycle), and emissions satisfy the future Euro IV standard.
The 1.6i 16V engine develops
80 kW EEC (110 bhp DIN) at 5,800 rpm and maximum torque of 147 Nm at
4,000 rpm. Highly responsive from the lowest engine speeds, this engine
offers torque of 132 Nm – 90% of the maximum amount – from 2,000 rpm.
This mid-range engine strikes an excellent balance between performance
and fuel consumption in combined use (7.1 l/100 km over a standard
The 2.0i 16V engine develops 100
kW EEC (138 bhp DIN) at 6,000 rpm with torque of 190 Nm at 4,100 rpm.
The high engine torque available from low engine speeds ensures a
smooth response to driver input. This engine offers torque of 165 Nm
from 2,000 rpm, almost 87% of the maximum torque available.
power of the engine combined with the strong, steady increase in engine
speed make the C4 138 bhp 2.0i 16V a pleasant and relaxing drive,
offering superior responsiveness and acoustics.
The 2.0i 16V engine is
also available with the C4 Saloon, in a version offering output of 103
kW EEC (143 bhp DIN) at 6,000 rpm. It is coupled with an automatic
gearbox. Recently introduced on the C5, this new version of the 2.0i
16V engine offers maximum torque of 200 Nm at 4,000 rpm. It features
continuously variable valve timing (VVT) to optimise filling of the
combustion chambers at all engine speeds. This engine offers torque of
170 Nm from 2,000 rpm, almost 85% of the maximum torque available.
It also meets the requirements of the Euro IV emission standard.
The 2.0i 16V engine, developing
130 kW EEC (180 bhp DIN) at 7,000 rpm is the most powerful engine in
the range. The C4 Coupť is the first CitroŽn vehicle to offer this
engine. This engine combines dynamic driving thrills with a high level
of safety and daily comfort of use. Maximum torque is 202 Nm at 4,750
rpm. On this engine, the intake camshaft is also equipped with a
continuously variable valve timing system. This characteristic makes
for a powerful, responsive engine.
THREE DIESEL ENGINES OFFERING EXCEPTIONAL PERFORMANCE AND FUEL CONSUMPTION
C4’s three HDi engines are all equipped with second-generation
common-rail. The 1.6 HDi 92 bhp is making its debut on a PSA Peugeot
CitroŽn Group vehicle, while the new HDi 110 and HDi 138 engines were
recently introduced in the CitroŽn range.
characteristics and performance of these compact, low-weight engines
are exceptional: driving pleasure, reduced fuel consumption and
pollutant emissions are combined with acoustic comfort and vibration
control. The engines are also remarkable for their verve, and for the
temporary torque increase of 20 Nm made available by the overboost
function, which is present on the two most powerful versions.
The HDi 138 engine is coupled with the six-speed manual gearbox, recently introduced on the C5.
The new 1.6 HDi 16V engine develops
66 kW EEC (92 bhp DIN) at 4,000 rpm and torque of 215 Nm at 1,750 rpm.
Based on the HDi 110, this “allaluminium” engine is making its debut in
the CitroŽn range. With low fuel consumption (4.7 l/100 km over a
standard combined cycle) and CO2 emissions of just 125 g/km, this engine satisfies the Euro IV standard.
The 1.6 HDi engine is
also available in a version offering output of 80 kW EEC (110 bhp DIN)
at 4,000 rpm, introduced on the Xsara Picasso in February 2004. It
supplies maximum torque of 240 Nm at 1,750 rpm. Torque can be increased
to 260 Nm at 1,750 rpm on the three highest gears, thanks to the
For strong bursts of acceleration,
the overboost function kicks in, delivering up to 20 Nm of additional
torque by increasing the fuel injection rate. This new engine therefore
combines a fast response with a linear increase in power, and excellent
acceleration at low engine speeds.
The HDi 110 features a
second-generation injection system delivering injection pressure of
1,650 bars, controlled by piezoelectric-type injectors. A
variable-geometry turbocharger enhances driving pleasure and
performance. This engine makes full use of the potential offered by the
common-rail system with its multiple injection technology and the
enhanced management of fuel injection into each cylinder, providing
four injections per engine cycle:
• two pilot injections to reduce combustion noise,
• two main injections to reduce nitrogen oxide emissions at source.
When it is equipped with the particulate filter, two additional postinjections improve the regeneration efficiency.
a result of its low fuel consumption – 4.7 l/100 km over a standard
combined cycle – and its 60-litre tank, this engine offers a range of
more than 1,200 km. CO2 emissions are also very low, at 125 g/km.
Euro IV version, available in some countries from the launch of the C4,
is equipped with the diesel particulate filter system (DPFS), which
traps and destroys particulates.
The 2.0 HDi engine complies
with the Euro IV standard and is coupled with the diesel particulate
filter system (DPFS). It develops 100 kW EEC (138 bhp DIN) at 4,000
rpm. Offering maximum torque of 320 Nm at 2,000 rpm, it also features
an overboost function that raises torque temporarily to 340 Nm. This
new engine is coupled with a six-speed manual gearbox already available
with the C5. The HDi 138, like the HDi 110, features a
second-generation injection system and a variable-geometry turbocharger.
