VOLKSWAGEN PASSENGER CARS
Engines with patented BlueMotion technologies, which offer all kinds of innovations that consider economic driving and environmental factors, consist of 97% of Volkswagen Passenger Cars’ 2016 sales and have increased 12% compared to year 2015. Furthermore product-based collaborations have been going on with Volkswagen AG to introduce Passat GTE in Turkey. This plug-in hybrid model can run 50 km using electricity alone. In the meantime after discussions and negotiations with suppliers in Turkey, charging stations have been installed in the Doğuş Otomotiv Head Office and training buildings.
The SCR (Selective Catalytic Reduction) technology, first used in the Volkswagen models’ 1.6 TDI engine option in Turkey and introduced with the new Tiguan, is based on purification of exhaust gases via the AdBlue injected directly into the exhaust pipe from the engine. The ammonia molecules, released as a result of the water evaporating in the AdBlue that is injected into the high-temperature exhaust gas, react with the harmful nitrogen oxides in the air as they pass through the SCR catalytic convector, and transform them into nitrogen and water vapor in the air. AdBlue is a mixture of 31.5% urea and 68.5% water that converts toxic nitrogen oxides (NOx), Carbon monoxide (CO) and hydrocarbons into harmless nitrogen (N2), carbon dioxide and water vapor (H2O). It is colorless, odorless, and harmless.
These technologies, which include low friction resistance tires, Start/Stop System and Brake Energy Recovery system along with TSI, TDI and DSG, previously available only in Touareg and Passat models as of 2011, are now offered in Polo, Golf, Passat, Volkswagen CC, Tiguan and Touareg models as well.
The Start/Stop System helps to reduce CO2 emissions. The car cuts down fuel consumption and CO2 emissions by turning the engine off when stopping at traffic lights. Brake Energy Recovery System on the other hand relieves the alternator from the engine during acceleration, thus using engine power only for acceleration, and disabling the electrical system that consumes unnecessary fuel. In this process, the car’s electricity is provided by the battery. During braking, the alternator increases engine brake effect by drawing more power than normal from the engine, and rapidly recharges the battery at the same time.
In addition to all of these, recyclable parts are widely utilized in Volkswagen Passenger Cars models, and in the production of plastic and glass materials, in particular. Furthermore, friction elements such as brake pads that do not contain asbestos, known to be harmful to the environment and human health, are extensively used across the entire model range.
VOLKSWAGEN COMMERCIAL VEHICLES
Volkswagen Commercial Vehicles models feature environment-friendly engines developed with multiple award winning Volkswagen technologies. The double turbocharge engine option, available in Amarok and Crafter, offers lower fuel consumption with smaller cylinder volume, and high torque at lower speeds and wider speed range. All the Commercial Vehicles, with their specifications and Volkswagen’s efficient engine technology, stand apart as models that provide solutions to various needs of different segments. Meanwhile another Volkswagen Commercial Vehicle, Caddy, as the only vehicle in the range with 7-speed DSG transmission and Hill Start Assist option features a 102PS TDI Engine that is noteworthy with its low fuel consumption of 5.2 lt/100 km.
In 2013, a product training event was organized for sales consultants working at our Authorized Dealers. All printed materials used in the event such as room cards, badges and programs were produced from recycled paper to raise awareness among Authorized Dealers. We aim to raise awareness further by using the same materials in the upcoming Authorized Dealer trainings.
During the new Amarok launch in 2016, a total of 550 people including 450 from Authorized Dealers and After-sales Services attended training about the vehicle. In the theoretical part of this training, the product features were explained in detail, and in the practical part, an off-road experience was offered in the company of professional drivers. In this manner, information about a technical vehicle such as Amarok was provided in real life conditions to ensure that the learning process was fast and effective.
Certain system developments were made on Turkuaz in 2014 with the aim of eliminating paper waste and their impact on the environment that physical invoices, required for vehicles serviced by Volkswagen AG Germany, create, and resulted in avoiding waste caused by mailing. Ongoing system improvements on Turkuaz every year enable us to accurately and properly print out invoices on a single page rather than requesting them from authorized dealers. This practice leads to savings in annual paper consumption, and contributes to the protection of the environment.
Starting with June 2013 production, all new Audi models, e.g. the new A8 Family, feature engines in Euro 6 emission norms, which define lower exhaust emission and fuel consumption rates. Furthermore, technological studies on environment-friendly models and products such as “Audi Lightweight Construction Technology” are ongoing.
Audi AG, considered a worldwide pioneer in lightweight construction, joined the Aluminium Stewardship Initiative in 2013 to ensure the sustainability of aluminum, the basic material of the system. As the leader of lightweight construction technology in the automotive industry, Audi aims to create a global standard for sustainable aluminum, and to reduce the environmental impact of cars further by using certified aluminum in the future. The Aluminium Stewardship Initiative, launched in 2012, and supported by the environmental organization International Union for Conservation of Nature (IUCN) until the end of 2014, aims to develop a sustainable standard for aluminum, and to determine environmental and social criteria in all steps of raw material extraction, aluminum processing and production.
The standards developed by the Initiative overlap with Audi’s holistic product sustainability approach. Audi, as the producer of premium cars, does not settle with high levels of fuel efficiency alone, and goes further by also analyzing the environmental impact of its products in their entire life cycle from the extraction of raw materials, to production and recycling. Aiming to understand the environmental impact of each new product series, Audi continues to conduct certified environmental impact analyses.
Audi uses ultra lightweight construction technology to ensure that many of its new models have a better environmental footprint than previous generations. For instance, in addition to sustainable material and production processes, the ultra lightweight construction alone has reduced the weight of the new A3 by as much as 80 kg compared to the previous generation. The new Audi TT offered in 2014 was 50 kg lighter, while the new Q7 launched in 2015 was 325 lighter than the outgoing version. Even though the Audi A4 comes with larger dimensions in 2016, the weight has been reduced by as much as 120 kg depending on the engine option.
The ASF (Audi Space Frame) technology introduced in an unpainted and polished aluminum body at the Frankfurt Auto Show 20 years ago was used for the first time in serial production of the first A8 model in 1994. The full aluminum body of the car weighed only 249 kg. With its ultra lightweight construction technology, Audi applies a rational material mix in line with the philosophy of “using minimum quantity of material in the right place”. Lighter construction brings with it more driving pleasure, improves security and has less impact on the environment. In other words, each kilogram saved in this manner leads to lower fuel consumption and CO2 emission.
Enhancing its environmental sensibilities with each passing day through the use of lighter materials, Audi began using fiberglass shock absorbers, which were developed with ultra lightweight construction philosophy and are 40% lighter than steel, in series production models in 2014. The ultra light shock absorbers, developed by Audi engineers as a result of long R&D efforts, are produced by shaping fiberglass and coating it with epoxy resin. Even though thicker than their steel counterparts, the new green colored shock absorbers are lighter and stronger. While a steel shock absorber used in an upper middle segment car weighs 2.2 kilograms, the fiberglass shock absorber developed by Audi weighs only 1.6 kilograms, lending to 40% savings in weight.
Fiberglass shock absorbers are less affected by chemicals used in car cleaning or pebbles that may bounce off in poor road conditions. Audi has been using its new generation of shock absorbers in upper middle segment models since late 2014.
In 2015 Audi succeeded in producing a synthetic diesel fuel from just water and carbon dioxide. Audi’s carbon-neutral e-Diesel can be used on its own in a more sustainable way.
Audi’s e-Diesel developed in partnership with Dresden-based clean technology company Sunfire requires only water and carbon dioxide as raw material for production. The water is first heated to 800 °C, and then split into hydrogen and oxygen with a process involving electrolysis. Hydrogen is then combined with carbon dioxide gas under high heat and pressure. The chemical reaction of these two gases results in “Blue Crude”, a liquid fuel made from long-chain hydrocarbons. This crude fuel is then refined, and converted into Audi e-Diesel. The end product is a synthetic diesel with superior combustion properties, and the fact that it lacks sulfur and aromatic hydrocarbons makes it more environmentally friendly. The first sample of Audi e-Diesel obtained after four months of research has already been tested to power the Audi A8 owned by German Federal Minister of Education and Research, Professor Johanna Wanka. The resulting synthetic fuel can be used both to power cars and also in place of traditional diesel in industrial applications.
Developments about Audi’s environmentally sensitive investments and products are shared with customers on the company website, as well as through press releases, and occasional press trips and fairs.
Recently, Audi has restricted the number of printed catalogs, and instead of distributing them at fairs and events, our customers have been directed to online catalogs viewed on their mobile phones or on our website.
In 2016, Audi introduced the hydrogen-fueled version of the Audi quattro concept car, which was previously presented with electrical versions. The Audi h-tron quattro concept again offers an electric drive. But this time, the source of the electric energy that drives the car is not the electric charge, but the hydrogen fuel cells. The Audi h-tron quattro concept runs on two electric engines, one in the front and one in rear. The front engine generates 120 HP (90 kW), and the rear engine 187 HP (140 kW). These two engines allow the concept car to reach from 0 to 100 kilometers per hour in under 7 seconds. The hydrogen tanks of the Audi h-tron quattro concept can be filled in 4 minutes. The car can travel up to 600 kilometers on a full tank. The concept car also benefits from numerous electronic security and entertainment systems that Audi will start using in production cars in the coming years. The vehicle, fitted with zFAS, the Central Driver Assist Control System, can drive autonomously up to 60 kilometers per hour, thus making autonomous driving possible in city centers and in packed traffic. Audi’s new A8, which will be available for sale in 2017, will offer assistance and security systems similar to those used in the Audi h-tron quattro concept.
As car manufacturers operating in the electrical automotive industry perform R&D work and conduct research on first the source of energy and then its consumption, regenerating electricity within the automobile system has great importance. Audi engineers have developed a very important prototype that will enable electric energy to be regenerated in the driving system. The system, called the eROT, allows electricity to be generated from the shock absorbers. Every bump, pothole or bend on the road moves the vehicle up or down, left or right, generating kinetic energy. The hydraulic shock absorbers used in cars today absorb and lose this kinetic energy generated from motion. On the other hand, the eROT, developed by Audi, enables this kinetic energy to be converted to electrical energy by electric engines used instead of shock absorbers. And this electric energy is transferred to the electric drive system to move the car. The eROT transfers all kinds of motion, or kinetic energy, coming from the wheels to the electric motor via various components. And this engine converts this power into electrical energy. This system can generate an average of 100-150 watts of electrical power, and in some road conditions it can reach up to 613 watts. The eROT offers much more comfort than conventional hydraulic shock absorbers. Moreover, due to its geometry, it also creates new possibilities in cars. Unlike hydraulic shock absorbers placed perpendicular to the ground, the parallel eROT thus does not take up much space, and in particular makes the trunk volume even deeper.
Porsche aims to offer environmentally friendly ideas, technologies and innovations in each vehicle, as well as superior driving performance. For this reason, Porsche engineers carry out R&D activities to reduce fuel consumption, CO2 emissions and the release of harmful substances to the environment, and to use more recycled materials. In the last 15 years, Porsche has reduced average fuel consumption and CO2 emissions by 1.7% every year, attaining one of the most successful improvement rates in automotive industry.
SEAT uses TSI, TDI, and the latest technologies that improve performance and driving comfort while reducing consumption and emissions. These are offered in Alhambra, Ateca, Ibiza, Leon and Toledo models and vehicles with Start & Stop feature in Turkey. Seat’s Leon model with EcoTSI ACT engine option achieves lower fuel consumption by shutting down cylinders 2 and 3 under 130 km/hour and between 1,250 – 4000 rpm.
All SEAT products reduce the emission of environmentally harmful gases thanks to their engines compliant with Euro 5 and Euro 6 norms. We will continue to use ecomotive engines, start&stop feature, and ACT engine technology in our upcoming models.
Scania serves its customers with a wide range of products to meet their demands. The range includes a total of 18 engines, all in Euro 6 norms including 11 diesel and 2 gas versions, and a 100-percent biodiesel fuel version with 5 options, and powers from 250 HP up to 730 HP.
The New Retarder leads Scania’s efforts toward reducing fuel consumption. Launched at IAA, the new Retarder turns off automatically when not in use, decreasing losses caused by friction. In long-haul transportation and high speed cruising, the internal resistance within the transmission decreases, resulting in fuel savings of 0.7 – 1.4%.
Eco-roll is another new system, where the combined use of Scania Active Prediction and Opticruise features provides fuel savings. The system calculates the most advantageous conditions for driving downhill when the vehicle is in neutral gear, and utilizes them. Driving downhill in neutral gear can lead up to 2% in fuel savings, which may vary depending on how bumpy the road is. The system, which activates itself by calculating and determining the more advantageous way at that moment, will most likely be introduced in 2017 in Turkey.
Scania's G410CA features a number of specifications for off-road conditions. The vehicle is fitted with a steel bumper against impact from uneven surfaces, air suction suitable for dusty working environments, axles and suspensions with 7,500 kg in the front and 13,000 kg in the rear, and air spoilers suited for tipping bodies and cement trailers used in construction / mining superstructures. The Scania G410 LA is a 4x2 tractor designed particularly for the application of semi-trailers with tipping bodies, cement trailers and container carriers, and offers fuel economy as well as enabling adaptation to rigorous and partial off-road operating conditions thanks to its features. The Highline cabins provide more living space. The aerodynamic plastic bumper is suitable for high average speeds on the roads. Both models have a 410 hp 13-liter engine, and 12 forward, 2 reverse and 2 crawler gears. The two-pedal Opticruise Transmission is available in economy and standard versions, delivering a torque of 2,150 Nm at a range of 1000 - 1300 rpm. Trailers with Scania R cabins are also offered with a 450 hp engine, generating up to 2,350 Nm torque.
The greatest impact of the automotive industry on the environments is the increase in air pollution and greenhouse effects due to exhaust gases. As a precaution, Scania has been using Euro 6 engine exhaust emission standard instead of Euro 5 in Europe since 2011. There are exhaust treatment systems that reduce the NOx level by 80% and cut the exhaust soot and particulate levels in half compared to Euro 5 standards. Scania has also invested in alternative fuelled vehicles, and developed 2 different engine options with natural gas. As forward-looking projects, full electric vehicles and autonomous vehicles are innovations currently being developed. Another environmental contribution is made to improve passenger, pedestrian and traffic safety. This includes accident prevention systems such as ESP stability program against tipping and skidding, AEBS advanced emergency braking, and LDWS lane departure warning.
As of 2016, Euro 6 engines with lower emissions come as standard in all Scania vehicles. Natural gas powered alternative fuelled vehicles have also been introduced during the year. By 2017, our products will feature Euro 6, natural gas and bio-diesel compatible engines. The Euro 6 engines developed by Scania not only provide fuel savings, but also protect the environment. While a vehicle with a Euro 6 engine produces 84 kg of CO2 emission per 100 km under normal conditions, this rate decreases by 9.1% down to 77 kg in Scania Streamline vehicles with Euro 6 engines. Considering a 120,000 km journey per year, this rate stands out as a remarkable data.
The most important difference in this regard is Scania's largest motor option in the market, with low fuel consumption valuesresulting from independent tests. Fuel savings delivered in long distances by Scania’s 320, 360, 410 and 450 hp engines with only the SCR system have also been proven by tests.
Furthermore, applications (Adblue cancellation, cruise control cancellation) that might have an impact on traffic safety and environmental cleaning are checked at Authorized After-Sales Services and via the vehicles’ satellite connections, precautions are taken.
