ENGINES DEVELOPED FOR EFFICIENCY AND PERFORMANCE
1.1 PureTech 130 S&S engine / 6-speed manual gearbox
Designed and built in France, the PureTech engines are a new family of 3-cylinder petrol engines based on innovative, efficient and economical technologies.
In 2014, the PureTech family gained a turbocharged version, the
PureTech 130 S&S, the first petrol engine developed by the PSA
PEUGEOT CITROĖN Group to respect the Euro 6 standard. Delivering plenty
of torque from low revs and across a broad brand, this powertrain
revisits the driveability of petrol engines, further enhancing the
punch and performance of the DS 4. The technologies used set remarkable
standards in performance while keeping CO2 emissions on a par with the
best: the PureTech 130 S&S engine with a 6-speed manual gearbox
reduces fuel consumption and CO2 emissions by 19% compared with its
4-cylinder predecessor (VTi 120).
Exceptional driving pleasure
With its 3-cylinder layout and advanced technologies (new-generation
turbocharger, direct injection, variable intake and exhaust timing
system, etc.), this engine was developed to meet stringent
specifications in performance and consumption, while delivering
Developing 96 kW (130 bhp) at 5,500 rpm (9% more than its predecessor,
the VTi 120) and maximum torque of 230 Nm (44% higher than the VTi 120)
from 1,750 rpm (vs 4,250 on the VTi120), the PureTech 130 S&S
engine meets high standards in performance. The 6-speed manual gearbox
further increases driving pleasure.
Fuel consumption and CO2 emissions on a par with the best in class
The DS 4 features significantly lower fuel consumption with its:
optimised combustion: centrally positioned
high-pressure direct injection, optimised injector position and spray
shape, increased injection pressure of up to 200 bars, improved
internal aerodynamics of the combustion chamber and a variable intake
and exhaust timing function;
reduced internal friction: crankshaft sizing, offset
cylinders a lubricated timing belt, use of a DLC (diamond-like carbon)
low-friction coating on the piston pins, rings and push rods, and an
oil pump controlled electronically to provide just the right amount of
lubrication. In this way, friction is 30% lower than on the best engine
made by the competition.
In consequence, the DS4 PureTech 130 S&S with a 6-speed manual
gearbox consumes 5l/100 km for CO2 emissions of 116g/km with 16’’
wheels (5.1 l/100 km for CO2 emissions of 119g/km with 17’’ wheels).
1.2 BlueHDi 120 engine / 6-speed manual gearbox
At the end of 2013, DS rolled out a new generation of diesel engines called BlueHDi, designed to anticipate the Euro 6 standard.
The BlueHDi 120 engine with a 6-speed manual gearbox now available on
the DS 4 allies excellent performance with particularly low fuel
consumption and CO2 emissions owing to:
An optimised diesel engine
The BlueHDi 120 engine with a 6-speed manual gearbox is an upgrade of the 1.6l HDi Euro version:
improved internal efficiency, fewer mechanical losses (special combustion chamber, new rings, new diamond-like carbon coating).
The BlueHDi 120 with a 6-speed manual gearbox has capacity of 1,560 cm3
for maximum power of 88 kW (120 bhp EEC) at 3,500 rpm and maximum
torque of 300 Nm at 1,750 rpm. The Stop&Start function with a
reinforced starter delivers a range of benefits including lower fuel
consumption and greenhouse gas emissions. It is also silent when
stationary. The engine takes no more than around 500 ms to start up
again, less than the time necessary to put the car into gear. Both
cut-out and re-start are transparent for the driver.
An innovative and efficient exhaust line:
The BlueHDi 120 exhaust line comprises:
an oxidation catalytic converter positioned at the engine exhaust to
eliminate the hydrocarbons (HC) and carbon monoxide (CO) produced
an SCR (Selective Catalytic Reduction) module, positioned upstream of
the particulate filter. With the injection of Adblue® (a mixture of
water and urea), the module transforms up to 90% of nitrogen oxides
(NOx) into inoffensive water vapour (H2O) and nitrogen (N2);
an additive particulate filter, launched as a world first in 2000 by
the PSA PEUGEOT CITROĖN Group designed to eliminate up to 99.9% of
particulates in number.
The innovative and unique feature of this exhaust line lies in its
specific layout: the SCR module positioned upstream of the additive
particulate filter is the only after-treatment system able to reduce
NOx emissions by up to 90% as well as reducing CO2 emissions by up to
In consequence, a DS 4 equipped with the BlueHDi 120 engine and 6-speed
manual gearbox consumes 3.7l/100 km over a combined cycle for CO2
emissions of 97g/km with 16’’ wheels (3.8l/100 km for 100g of CO2/km
with 17’’ wheels).
