Renault is developing a range of vehicles running on bioethanol Renault hails the French government’s initiative announced on September 24 to begin deploying a bioethanol distribution network in France in 2007. Under the Renault Commitment 2009 business plan, 50% of gasoline-powered engines for sale in Europe in 2009 will be able to operate on a mixture of gasoline and ethanol. At the Paris Motor Show (September 28 to October 15, 2006) Renault will present a Mégane running on bioethanol (E85), which will be rolled out in Europe in 2007. It is also preparing to market a full line of biofuel-compatible vehicles (bioethanol and biodiesel). These models will be rapidly distributed through Renault's sales network in France. In terms of fuel economy and CO2 emissions, the Renault lineup is among the most efficient in the world today. The company is aiming for even better results, and by 2008 it will sell one million cars emitting less than 140 grams of CO2 per kilometer, of which onethird will emit less than 120 grams.

Bine, renault deja produce niste masini care merg cu niste amestecuri dubioase prin america de sud. Chiar si loganul are in plan (daca nu o fi si produs in columbia) un motor care sa mearga pe nu stiu ce versiune de alcool. Cica prin america de sud nu sunt ceva iesit din comun masinile pe spirtoase

In Brazilia se pare ca are mare succes. Vreo 70 -80% din masini merg cu asa ceva. Si aia o numesc biodiesel si o fac din trestie de zahar. Renault e infipt bine pe piata acolo, cu motoare speciale care pot merge cu asa ceva.

Da, dar si in Statele Unite sunt multe masini multi-fuel si o retea de distributie de E85. Din pacate consumul lor fiind de vreo 15 ori mai mare decat al Braziliei sansele sa isi produca singuri etanolul sunt mai mici. Totusi e un pas (mare) spre independenta de importuri de petrol.

Americanii fac etanolul din porumb, ca le ei cu trestia e mai restrans...

@sebybv: ai dreptate, in Brazilia combustibilul de baza este etanolul, sau benzina amestecata cu etanol.

Dar... nu se numeste biodiesel. Aia e altceva: e un inlocuitor pentru motorina (in timp ce etanolul este inlocuitor pentru benzina).

Combustibilul de acest tip este o alternativa, eu mi-as cumpara o masina "bio", stiind ca poluez mai putin mediul inconjurator, dar...

- este imposibil ca toti sa trecem pe bio-combustibil. Unde am planta toata trestia de zahar necesara???
- daca procesul de fabricatie al acestui combustibil nu este "curat", atunci argumentul de protectia mediului nu este valabil


Eu cred ca va constitui doar o tranzitie, pentru momentul in care nu va mai fi petrol, sau va fi atat de scump, incat mai bine plantezi trestie de zahar in gradina. Dupa capul meu, adevaratul sistem de propulsie al viitorului indepartat va fi pila de combustie.

Bio-etanolul are viitor! Pentru ca se poate produce direct din celuloza, ceea ce inseamna cam orice deseu vegetal din lume (gandeste-te la paiele cerealelor, iarba de stepa, frunzele cazute toamna ale padurilor de foioase, deseuri lemnoase, stuf, etc...) Procesul tehnologic pt. productie pe scara industriala nu e inca perfectat, dar un concern din SUA a anuntat ca va deschide prima fabrica anul viitor.

Azi boietanolul se produce din zahar sau amidon, ceea ce limiteaza mult cantitatea de materie prima disponibila, dar daca intra pe scara larga productia din celuloza...

Suna frumos, dar ce efort logistic trebuie facut pentru colectare, depozitare, transport? Din ce cantitate de materie prima rezulta 1l de bio-etanol, ce consumuri energetice sunt, ce costuri cu forta de munca, cat costa tehnologia, etc.
Deocamdata sunt solutii partiale la problema (ard gazul/motorina in centrala termoelectrica in loc sa-l ard in motor).

Inauguration of first pump delivering bioethanol E85

French ministers Thierry Breton and Dominique Bussereau testdrive a Mégane fuelled by bioethanol E85

To mark the inauguration of the first bioethanol E85 pump in Paris, industry
minister Thierry Breton and agriculture minister Dominique Bussereau topped up
to take a spin in a Mégane 1.6 16v bioethanol E85.

“Government ministers Thierry Breton and Dominique Bussereau have test-driven a Mégane running on bioethanol E85, an event that highlights Renault’s commitment to biofuel development,” declared Luc-Alexandre Ménard, Renault’s senior VP for public relations, who also noted that ”this Mégane, which runs on bioethanol E85, will be released on the French market in spring 2007”.
One of the undertakings under the Renault Commitment 2009 programme is that half of the petrol-fuelled Renaults sold in Europe will run on a mixture of petrol and bioethanol by 2009. To follow on from this Mégane, Renault will be launching a full range of biofuelcompatible vehicles, running on bioethanol and biodiesel.
The Renault range is already one of the most environment-friendly in the world, as
regards fuel consumption and CO2 emissions. And Renault plans to improve this
performance further still, with annual sales of one million vehicles emitting under 140 g of CO2 per kg by 2008, and a third of these emitting under 120 g.

The 2007 Paris International Agricultural Show

Renault pursues its commitment to E85 bioethanol and B30 biodiesel biofuels

As in 2006, Renault will be present at the International Agricultural Show in Paris (March 3-11, 2007(1)). Renault's stand will highlight its active involvement in the development of biofuel-related technologies with the display of an E85 bioethanol Mégane alongside one of its B30 biodiesel-compatible engines, the 1.5 dCi 85hp.
In addition to the flash card-style 'Incollables' game it has developed with a view to promoting awareness of global warming-related challenges and which will be given away on its stand, Renault sets out to provide a pedagogical approach to questions relating to biofuel matters, such as why do biofuels need to be developed, how are bioethanol and biodiesel produced and what is the importance of 'well-to-wheel' analysis?

Renault considers biofuels to be one of the most effective and economical solutions for curbing CO2 emissions in the medium term. Produced from vegetable matter, they represent a diversified renewable energy source capable of diminishing our dependence on fossil fuels. An additional benefit of biofuels is the fact that they can be produced using local resources and consequently cut the CO2 emissions necessitated by transport by road or sea.

This spring, Renault is poised to launch a Mégane powered by an E85 bioethanolfuelled 1.6 16V 110hp engine, the brand's first bioethanol vehicle in Europe. Derived from existing powerplants in the range, such bioethanol engines require specific development to permit them to run on different types of fuel (petrol or E85 ethanol).
The principal differences concern the fuel system as a whole and the injection system (injectors, sparkplugs, ECU), as well as the pistons, valves and valve seats. Based on experience acquired since 2004 in Brazil, where it sells models functioning on E100 bioethanol, Renault anticipates that "50 per cent of its petrol-engined vehicles on sale in Europe will be able to run on a blend of petrol and up to 85 per cent of ethanol by 2009."

Since late 2006, Renault has sold B30 biodiesel-compatible versions of Trafic 2.0 dCi and Master 2.5 dCi. Aimed principally at companies operating large fleets and equipped with a specific pump, these vehicles cost the same as the equivalent conventional diesel-powered versions. They are also the first concrete examples of the pledge incorporated in Renault Commitment 2009 that "all the diesel engines in the range will be capable of running with 30 per cent biodiesel by 2009." The diesel 1.5 dCi 85hp engine displayed on the stand illustrates how these developments can be carried over to the world of passenger cars.

Renault's current range stands out as one of the most effective anywhere in the world in the realm of low fuel consumption and CO2 emissions. Another of the objectives set out in Renault Commitment 2009 is to go even further by selling 1 million vehicles by 2008 that emit less than 140g of CO2 per km, including one-third that emit less than 120g/km.

An educational approach to the importance of global warming-related issues

Informing the public and enhancing its awareness of the stakes associated with global warming are seen as primordial to Renault's eyes. This necessity is addressed by a bid to explain and communicate the advantages of automotive biofuels in the fight against CO2 emissions.
Visitors to Renault's stand will be informed about the advantages of biofuels and how the industry functions. The benchmark biofuel for petrol-powered cars is bioethanol which is produced from a variety of sources – ranging from corn (USA) and sugar cane (Brazil) to beetroot and wheat (Europe) – depending on the region of the world. Diesel vehicles are fuelled by biodiesel which is produced from oleaginous plants (rapeseed, sunflower, soya, jatropha, palm oil, etc.).

Visitors will also be told of the value of biofuels through the so-called 'well-to-wheel' analysis which assesses the CO2 performance of different fuel types across their entire life cycle. In the case of B30 biodiesel, CO2 emissions are 20 per cent lower compared with a conventional diesel fuel and can be as much as 70 per cent lower in the case of E85 bioethanol (derived from sugar cane) compared with petrol. These differences are the result of the process of photosynthesis. While growing, plants absorb a quantity of the CO2 present in the atmosphere, a factor which partially compensates for emissions released during the fuel's production and combustion. This phenomenon does not apply in the case of conventional fuels.
Moreover, just as it did during the 2006 Paris Motor Show, Renault will be giving away 20,000 free copies of its flash card-style 'Incollables' game. This educational tool was developed in association with France's Agence de l’environnement et de maîtrise de l’énergie (ADEME, or Agency for the Environment and Energy Management) and has been designed to inform and enhance awareness of environmental protection issues in the form of a quiz.

(1) The 2007 International Agricultural Show is held in Paris (Porte de Versailles). Renault's stand is located in Hall 2.2 ('Cultures et filières végétales').

Renault presents a range of affordable, environmentally sensitive vehicles

As part of its 'Commitment 2009' programme, Renault is pursuing an ambitious environmental plan to reduce greenhouse gas emissions. This is based on three axes: to be one of the world’s top three carmakers for low-level CO2 emissions, to offer a range of models powered by biofuels and to develop a wide range of alternative technologies. The first steps in this operation became a reality late in 2006, when Trafic and Master went on sale with engines capable of running on B30 biodiesel. In spring 2007, Renault will introduce a Mégane that runs on E85 bioethanol. The company will be one of only a few manufacturers offering vehicles that run on two biofuels (bioethanol and biodiesel).

Thanks to its ongoing work with diesel, petrol and biofuel engines, Renault is producing environmentally sensitive, affordable vehicles.
Under the terms of Renault Commitment 2009, Renault is firmly committed to cutting its vehicles’ CO2 emissions in order to help reduce the greenhouse effect. To this end Renault has set itself three major targets:
- Become one of the world’s top three car manufacturers in terms of CO2 efficiency. By 2008, through its '120/140' plan, Renault aims to be selling one million vehicles that emit less than 140g of CO2 per kilometre, with one third of those emitting less than 120g.
- Offer a range of vehicles running on biofuels. By 2009, 50 per cent of Renault petrol-engined vehicles marketed in Europe will be able to operate on blends of petrol and ethanol. Furthermore, all the brand’s dieselengined vehicles will, within the same timeframe, be able to run on fuel that is 30 per cent biodiesel.
- Develop a wide range of alternative technologies. Within the framework of the Renault-Nissan Alliance, Renault is preparing a broad selection of alternative technologies such as hybrid and electric vehicles and fuel cells. Within the framework of Renault Commitment 2009, Renault will conduct a series of tests in France with vehicles powered by fuel cells based on advanced Alliance technologies.

Renault on the fuel economy/low CO2 emissions podium

Renault’s engine efficiency has already made it one of the world’s top three manufacturers in terms of low CO2 output – a result that underlines the progress the company has made during a fuel economy drive stretching back almost 20 years. In 1993, for instance, a full tank would be enough to take a 93hp Renault 19 1.9DT the 786km between Geneva and Brussels with an average fuel consumption of 6.5 litres/100km (and CO2 emissions of 172g/km). By 2000, a Mégane 1.9 dTi 100hp Mégane could carry its occupants the 984km from Geneva to Amsterdam at 5.2 litres/100km (with CO2 emissions of 138 g/km). Today, a Mégane 1.5 dCi 105hp will cover the 1,114km from Geneva to Berlin with fuel consumption of just 4.5 litres/100km and CO2 emissions of 120g/km.

Its latest petrol engine, the TCE 100hp, is a perfect example of the vast expertise the company has accumulated. Delivering the 100hp output of a 1.4-litre engine and the 145Nm of torque associated with a 1.6-litre engine, this 1.2-litre powerplant, fitted to New Twingo, will record a combined cycle fuel consumption of 5.9 litres/100km (emissions 140g/km). Renault displays the same degree of expertise when it comes to diesels.
Powered by the 1.5 dCi 105hp engine equipped with a particulate filter, Mégane emits just 120g of CO2 per kilometre. In 2005 this made it the best car in its class in terms of CO2 emissions. In a Laguna, the 2.0 dCi 175hp engine with particulate filter is acknowledged for its remarkable balance between performance and fuel efficiency, which produces combined cycle fuel consumption of 6.0 litres/100km.

For Renault, the optimisation of conventional petrol and diesel engines remains one of the most cost-effective ways of controlling greenhouse gas emissions. In 2005, almost one in every five Renaults sold in Europe emitted less than 120g/km of CO2.

Bioethanol and biodiesel: two biofuel options in Europe

When an E85 bioethanol-compatible Mégane reaches the showrooms in spring 2007, to complement Renault’s existing B30 biodiesel commercial vehicles, the company will be one of only a few to offer European customers two biofuel options.
Since late 2006, Trafic has been available with the 90bnp and 115bhp 2.0 dCi B30 engines and Master with the 100hp and 120hp 2.5 dCi B30. Aimed principally at companies with large fleets, these vehicles can run with equal ease on diesel fuel or mixtures of conventional diesel and B30 biodiesel. Engines of this type will be available in Renault’s cars from 2008. For instance New Twingo, launched here in Geneva, will be sold with the B30-compatible 65hp 1.5 dCi engine.
This spring, Renault is introducing a Mégane powered by a 110hp 1.6 16V engine. It will run on E85 bioethanol and will be Renault’s first bioethanol vehicle in Europe. Derived from existing powerplants in the range, the engines have been modified to adjust automatically to different fuels. The main changes affect the tank, fuel injection system and combustion chamber. Since 2004, Renault has been selling E100-compatible flex-fuel Clio and Mégane models in Brazil.

Renault considers biofuels to be one of the most efficient and economical solutions for curbing CO2 emissions in the medium term. Produced from vegetable matter, they are a renewable, diversified energy source that will help limit dependence on fossil fuels. An additional advantage is that biofuel can be made from locally available resources, which cuts CO2 output by minimising the need for transport.

Since March 2006 Renault has been working with DaimlerChrysler, Volkswagen, Royal Dutch Shell and Sasol Chevron, as part of the Alliance for Synthetic Fuels in Europe (ASFE), to research second-generation biofuels. These are obtained using a method known as the Fischer-Tropsch process, using either natural gas (gas to
liquid), coal (coal to liquid) or biomass (biomass to liquid) as a base starting point.

What kinds of biofuel does Renault use for these vehicles?

Bioethanol is made by fermenting and distilling plant or vegetable matter, such as wheat or beetroot in Europe, sugar cane in Brazil or corn in the USA. Bioethanol can then be mixed with petrol in varying proportions: 5 per cent content is E5, 10 per cent is E10 and 85 per cent is E85. Flex-fuel vehicles like the Brazilian market Clio 1.6 16V Hi-Flex can burn neat bioethanol.

Biodiesel is an alkyl ester derived from vegetable oil. It is produced from oleaginous crops and plants (mainly rapeseed and sunflower in Europe, but also soya and palm oil in other parts of the world). Through a process known as transesterification, vegetable oil reacts with methanol to produce biodiesel which can then be mixed with straight diesel. When mixed with diesel at a rate of 30 per cent, biodiesel is called B30.

From well to wheel

To understand the advantages of biofuels over fossil fuels in reducing CO2 emissions, it is important to take a holistic, or well-to-wheel, approach. Well-to-wheel analysis serves to rate the efficiency of a fuel by calculating its aggregate CO2 emissions from when it is produced to when it is burnt in a vehicle.
Fossil fuels are responsible for CO2 emissions during production (drilling and refinery), when they are shipped and when a vehicle burns them. Biofuels originate from plants, which are grown to produce them, and the CO2 absorbed by the plants as they grow (photosynthesis) is subtracted from the biofuel’s total CO2 emissions.
What’s more, because biofuels can be made from locally available biological matter, there is much less need to transport them to distribution facilities by road or sea, which in turn limits CO2 emissions.
Total CO2 emissions produced by the biofuel chain are much lower than for conventional fossil fuels. Some biofuels can, depending on the plant material used to produce them, lead to reductions in CO2 emissions of up 70% compared to a petrol engine. The reduction can reach about 20% in the case of a biodiesel or diesel engine.

Mégane Hatch and Sport Tourer running on E85 bioethanol

Renault has chosen the Mégane range to introduce its first bioethanol (E85) cars on the European market. The new ecological and economic alternative is available on Mégane hatchback and estate cars with 1.6 16v engines, from the Authentique trim upwards. Prices start at €18,550 for Mégane Hatch and €19,150 for Mégane Sport Tourer, just €200 more than for the standard 1.6 16v versions.
French release for the E85 versions of Mégane Hatch and Mégane Sport Tourer is scheduled for late June 2007, though dealer orderbooks opened on June 11.

At the end of June 2007, Renault will be releasing its first bioethanol-compatible vehicles in Europe, in the form of Méganes powered by a 105 hp 1.6 16v engine running on E85 fuel. The existing 1.6 16v petrol engine underwent a number of modifications so that it could adapt automatically to the type of fuel. Main upgrades were to the fuel tank, injection system and combustion chamber. The new vehicles were developed with input from expertise developed in Brazil, where Renault has been selling FlexFuel versions of Clio and Mégane, running on bioethanol E100, since 2004.

The new releases should be seen against a backdrop of French tax incentives for clean vehicles, with full exemption from company car tax over eight quarters for passenger cars registered after January 2007, and partial or total exemption (depending on the region) from regional vehicle registration taxes for cars running on bioethanol E85.

Renault considers biofuels to be one of the most effective solutions in the long-term quest for control over CO2 emissions. Biofuels are ecologically effective, as a diversified, renewable, plantbased energy source. And they are economically effective because the cost of developing compatible engines is reasonable, and the cars therefore affordable. Biofuels will also be helping to cut down energy dependency on fossil fuels.

Biofuel-compatibility is one of the criteria behind the Renault Eco2 signature. With a Mégane running on bioethanol (E85) alongside other vehicles running on biodiesel (B30), Renault confirms its commitment to this technology, as one of the few carmakers to offer its European customers cars running on both types of biofuel.

Bioethanol is made by distilling fermented vegetable matter, typically in the form of wheat or beet in Europe, sugarcane in Brazil, or maize in the USA. The resulting fuel is then mixed with petrol in varying proportions: 5% for E5, 10% for E10, 85% for E85, and up to 100% for the Hi-Flex Clio 1.6 16v sold in Brazil.

in Romania ai unde sa alimentezi asa ceva? ma poate lamuri si pe mine cineva exact care e avantaju acestui combustibil? comparativ cu benzinaru care diferenta in termeni de consum / poluare ?

pretul stie cineva cum este? B30 vs diesel si E85 vs Benzina???E un pas inainte, dar daca nu iese mai ieftin si utilizatorul, mai e ceva pana sa fie la moda... Poate pentru ca masina dezvolta mai multa putere si un cuplu mai bun pe E85, lumea va fi tentata(poate si consumul va fi mai mic...)

This post has been edited by padual: 22 Jun 2007, 21:10

ambele sunt amestecuri de motorina/benzina cu etanol si motorina obtinuta din diferita plante (in, rapita, floarea soarelui).
marele lor avantaj e ca nu depind de resurse epuizabile iar UE deja a cerut ca in cativa ani, o anumita cota de prodcutie sa fie reprezentata de biodiesel si E85. la noi, momentan sunt doua sau trei fabrici de biodiesel, doar una e terminata din cate stiu dar toate vor exporta biodieselul pana vom avea si noi o retea de distributie.
in germnaia si tarile nordice deja se folosesc la scarta larga bioetanolul si biodieselul, precum si in america de sud, acolo cam 70-80% din consum, dupa cum s-a mai spus.

Motorul arde etanol, producand CO2. Plantele consuma CO2 si produc amidon sau zahar, care prin fermentare si distilare duc la etanol. Etanolul ajunge in masina si ciclul se reia. Prcatic, astfel nu se introduce C02 nou in atmosfera. Avantaj major la poluare.........

problema nu e ca se introduce co2 nou in atmosfera ci ca se defriseaza padurile in draci. iar pomii<plantele> care inainte inghiteau co2-ul dat de masini..acum nu mai are cine sa-l inghita.
in fine pe tema asta putem sa aberam mult si bine.
in alt aordine de idei, asa cum spuneam intr-un topic asemanator, dar cu referire stricta la logan, exista un importator si distribuitor de bioetanol<E85> in romania. mai exact in Bucuresti la reprezentanta Saab, care a pus in vanzare un model <85 aero> care merge si cu acest tip de combustibil.
