PEUGEOT: technological and environmental expertise

Faced with major issues around the environment and energy supply, PEUGEOT views innovation as an important lever for differentiation to position it as leader in many of the technologies for the protection of the environment, while still maintaining the level of driving enjoyment in line with the brand’s reputation.

This year, PEUGEOT’s environmental commitment can be seen in the offer of three HYbrid4 models, the extension through the model range of the PureTech three-cylinder petrol engines, the introduction of BlueHDi technology on Diesel engines, the arrival of new automatic gearboxes and the wider availability of the Stop&Start system.

In this way, the brand further reduced the average weighted CO2 emissions of its European range in 2013. With 115.2 g/km in 2013, against 121.6 g/km in 2012, PEUGEOT is on the European podium for the cleanest and most economical brands.

In 2014, PEUGEOT continues its efforts towards the objective of 2 l/100 by 2020 for an improvement in air quality.

The new PureTech three-cylinder turbo petrol engine

After the launch of the 1.0 litre and 1.2 litre naturally aspirated engines, the PureTech family of three-cylinder engines is expanded with the 1.2 litre e-THP 110 and 1.2 litre e-THP 130 turbocharged versions.

This diversity is achieved through the modularity that was part of the design brief for the engine. As a result, 40% of the components of the turbo engine are common to the naturally-aspirated engine. As regards the 110 and 130 hp PureTech turbo engines, they differ only by their calibration and gearboxes. 

Modular and compact, clean and powerful, this turbo engine is a concentration of efficiency and the latest technology. In its 110 and130 hp versions, it is intended for the core of the PEUGEOT range in segments B, C and later also D. 

The three-cylinder architecture and the technologies adopted allowed a demanding design specification to be met, delivering: 

  • reduced fuel consumption and CO2 emissions;

  • exceptional driving enjoyment;

  • reliability without compromise.

It offers excellent performance, in fuel consumption as well as in its dynamic sensations and flexibility in use.

Well controlled CO2 emissions

 The arrival of the new PureTech three-cylinder 1.2 litre turbo petrol engine represents a true technological step forward. Its compact size, reduced weight and innovative low-friction materials are key factors in the virtuous search for performance and economy. Defined with a high specific power output of 80 kW per litre and 190 Nm per litre, it represents an improvement in engine efficiency while reducing engine capacity at the same time.

The combustion system has been the subject of particular attention in order to make the most of the technologies used in the engine, with in particular the adoption of high pressure (200 bar) direct injection positioned centrally.

For equivalent power and driveability this new engine reduces fuel consumption and CO2 emissions by up to 21 %, compared to current four-cylinder engines.

So the new PEUGEOT 308 1.2 e-THP 130, associated with a six-speed manual gearbox, has fuel consumption on the combined cycle of 4.6 l/ 100km and CO2 emissions of 107 g/km.

The best low speed torque/maximum power compromise in the market

The new PureTech three-cylinder1.2 litre turbo petrol engine proves that downsizing can deliver performance and a great driving experience.

With high pressure direct injection and a new high-efficiency turbocharger (running at 240, 000 rpm), it offers exceptional driveability, and this from the lowest engine speeds. As the maximum torque of 230 Nm is obtained at 1750 rpm, it delivers the best low speed torque/maximum power compromise in the market. In addition, 95 % of the torque is available between 1500 and 3500 rpm, promising optimum operation in all circumstances.

A robust and innovative design, with no compromise on reliability

In addition to optimised combustion and reduced internal friction, the new PureTech three-cylinder petrol engine benefits from the great care taken in its construction.

By the time of its launch, the PureTech three cylinder turbo petrol engine will have been subjected to a severe test programme with more than 25 000 hours on an engine test bed and more than1.6 million kilometres of test driving.

It is on the new PEUGEOT 308 SW 1.2 litre e-THP 130 in April 2014 that the first application of the PureTech three-cylinder turbo petrol engine is seen. From July 2014, the 308 range will be rounded off with a 3-cylinder110 hp turbo petrol version as well as a new six-speed automatic gearbox on the 130 hp petrol version.

BlueHDi technology for a new range of Diesel engines

Once again PEUGEOT offers the most efficient emissions control technology in the market

The Particulate Filer (Filtre à Particules - FAP) launched as a world first by PEUGEOT on the 607 in 2000, eliminates 99.9% of particulates whatever their size – fine and ultra fine.Since 2007, the brand has applied the FAP very widely, generalising its use across the range, well before the Euro 5 standard imposed its application to all Diesel vehicles sold in Europe from January 2011.Since the end of 2013, the brand has been using the new BlueHDi technology which provides a drastic reduction in the emissions of nitrous oxides. Uniquely associating SCR (Selective Catalytic Reduction) and a particulate filter with additive, it allows the NOx emissions from new generation Diesel engines to be reduced by up to 90%, CO2 emissions and fuel consumption to be optimised, while still eliminating 99.9 % of particulates. 

The BlueHDi technology already comfortably meets the Euro 6 Diesel emissions standard and will be progressively introduced on all of the brand’s Diesel models and presents the best potential for meeting future emissions standards.

PEUGEOT continues the application of BlueHDi technology

Introduced on the 508 sedan and SW at the end of 2013 on the BlueHDi 2.0 litre 150 and BlueHDi 2.0 litre 180 versions, the new BlueHDi Diesel emissions control technology is now deployed on the PEUGEOT 308 and 308 SW with the BlueHDi 1.6 litre 100, BlueHDi 1.6 litre 120 and BlueHDi 2.0 litre 150 engines.

 On the BlueHDi 1.6 litre 120 version associated with a six-speed manual gearbox, the new PEUGEOT 308 and 308 SW establish a fuel consumption record in the segment with 3.1l/100km and 3.2l/100km respectively, equal to COemissions of 82 and 85 g/km on the combined cycle.

The new BlueHDi 2.0 litre 150 engine associates high performance with particularly well contained emissions. With a maximum torque of 370 Nm at 2000 rpm and great flexibility in use, on the new PEUGEOT 308 SW with a six-speed manual gearbox, it returns CO2 emissionsfrom 99g/km.

A new generation of even more efficient Euro 6 Diesel engines

BlueHDi 2.0 litre: high level performance and reduced fuel consumption

Already meeting the Euro 6 emissions standard, the new generation of BlueHDi 2.0 litre engine is available in 2 versions of increased performance compared to the generation they replace:

  • BlueHDi 2.0 litre 150 : its maximum power of 110 kW or 150 hp is delivered at 4000 rpm and its maximum torque is up to 370 Nm at 2000 rpm ;
  • BlueHDi 2.0 litre 180: its maximum power of 133 kW or 180 hp is delivered at 3750 rpm and its maximum torque is up to 400 Nm to 2000 rpm.

This new generation of BlueHDi 2.0 litre engines allows savings of 9 to 13 % in fuel consumption and CO2 emissions – except for Stop & Start – compared to the replaced Euro 5 versions, up to 4%  of which are directly attributable to the settings made possible by the SCR fitted upstream of the FAP.

 To obtain these levels of performance and fuel consumption, development was focused on three areas:

  • improved internal efficiency and reduction of losses ;
  • reduced weight;
  • the use of auxiliary systems kept strictly to what is needed.
BlueHDi 1.6 litre: driving enjoyment and record fuel consumption

The new generation of BlueHDi 1.6 litre engines is modified in ways that help improve fuel consumption, in terms of internal friction (piston rings/liners – engine oil), optimisation of the variable output oil pump and control of the cooling system thermostat. In addition, these engines are associated with manual or automatic gearboxes of improved efficiency, as well latest generation Stop&Start using an alternator-starter or starter motor (depending on version).

On the new PEUGEOT 308 BlueHDi 1.6 litre 120, it is the unique association of a vehicle designed with reduced weight, a power unit that is both economically and powerful, optimised aerodynamics and ultra low rolling resistance tyres that allows it to claim to be the benchmark in the market for fuel consumption and CO2 emissions.


New automatic gearboxes for driving pleasure and environmental efficiency

Designed and developed in collaboration with AISIN AW, the biggest manufacturer of automatic gearboxes in the world, a new family of six-speed automatic gearboxes of unequalled performance is available on PEUGEOT vehicles.

The AM6 III, coupled with the BlueHDi 2.0 litre, and the AT6 III, soon to be available with the PureTech 1.2 litre turbo petrol, ensuring a high level of driving enjoyment with fast gear changes and reduced fuel consumption. As a result, for an equivalent engine and tyre fitment, the difference in CO2 emissions compared to a vehicle with a manual gearbox is less than 10 g/km in all cases, and is merely 1g/km difference on the PEUGEOT 308 BlueHDi 2.0 litre 150.

Thanks to the work done on reducing internal friction and the association of torque converters that can be locked up whenever needed to avoid slip, the efficiency of these automatic gearboxes is almost the same as a manual gearbox while maintaining driving enjoyment of the highest level.

As regards the speed and smoothness of the gear changes, these six-speed transverse gearboxes use Quickshift technology and currently offer the best compromise between size, cost and efficiency compared to the 7, 8 or 9-speed gearboxes available in the market.

First used on the 508 BlueHDi 2.0 litre 180, the new AM6 III gearbox is also available on the new 308 and 308 SW, associated in this case with the BlueHDi 2.0 litre 150 engine. It has also been designed to drastically reduce CO2 emissions. So on a 308 the difference in emissions compared a manual gearbox is reduced to 1g/km (for the same tyre fitment), making this version extremely well placed in terms of driving pleasure and fuel consumption.

First adaption of a Stop & Start system to a vehicle with an automatic gearbox

For the first time on a PEUGEOT, a Stop&Start system with alternator-starter – or reversible alternator – has been adapted for operation with an automatic gearbox. Recognised as the best system in the market, the e-HDi micro-hybrid technology contributes towards the reduction of CO2 emissions, which can be as much as 15 % lower on the urban cycle. As regards comfort in use, it also has many strong points: silence, speed of operation, absence of vibration, on-board systems maintained and operation in a temperature range down as low as -5 °C.

Applied for the first time to a 2 litre Diesel engine, this technology is available as standard, on the BlueHDi 150 and 180 versions, with both types of gearbox, manual and automatic.

So, with its new PureTech petrol engines and the BlueHDi Diesel technology meeting the Euro 6 emissions standards, its efficient and robust automatic gearboxes and its benchmark Stop & Start technology, the PEUGEOT brand demonstrates once again its ability to react and innovate. PEUGEOT’s technological advances allow it to offer a range of vehicles that not only deliver performance, reliability and economical operation, but also provide a unique level of driving enjoyment in line with the brand’s reputation.
