2009 Volkswagen Polo BlueMotion Concept

It is still a concept - the most fuel efficient five places in the world. Your name: Volkswagen Polo BlueMotion Concept. Fuel consumption: 3.3 liters of CO2 emissions: only 87 g / km! Likely to enter production: very high! However, before launching a potential production, development should be completed in the new 1.2 liters TDI with common rail injection. And that is precisely what the team led by Head of Development Dr Ulrich Hackenberg is working with great emphasis. "I hope," says Dr. Hackenberg, "we are able to enter production in February 2010. Meeting this schedule will be very demanding. However, the engine and other systems of the Volkswagen Polo BlueMotion concept are already in operation with these promising performance that we are on track to achieve our goal. "

The "other" referred to include an automatic start-stop system and regenerative braking. These two technologies alone to reduce the fuel consumption of 55 kW / 75 hp three-cylinder direct injection diesel by up to 0.2 liters per 100 kilometers.

But that's not all you're doing. In the Volkswagen Polo BlueMotion Concept car, which weighs just 1080 kg, Volkswagen requested a range of efficiency measures, including an aerodynamic package for the Volkswagen Polo, a body is reduced by 10 mm (including modified front), a aerodynamically optimized low and low rolling resistance tires on 15 inch alloy wheels. Together, these changes yield total savings of 0.8 liters of fuel. This has reduced CO2 emissions by 20 percent.

Other features that are in the Volkswagen Polo BlueMotion Concept car at the Geneva Motor Show 2009 includes a custom interior with "power" of court, and a display to indicate upshifting and tire pressure. The study design is painted in the new exterior color "Blue Emotion."

Start-stop system in detail

Particularly useful is a look at the full intuitive operation of start-stop system. As the driver approaches a red light in the Volkswagen Polo BlueMotion Concept car, he or she applies the brakes to stop the vehicle, changes in neutral (which should be standard practice with a conventional car) and has your foot off the clutch. This engine is turned off momentarily. A "Stop Start" message appears in the multifunction display. As the traffic light turns green again, the driver depresses the clutch fully, the engine starts, the "Start Stop" message disappears, and the driver puts the car in motion and resumed driving.

Regenerative braking in detail

Regenerative braking helps to recover energy that would otherwise be lost in a drive as efficiently as possible. During phases of deceleration and braking of the Polo BlueMotion concept car - that is, just when the driver releases the accelerator pedal or brake intentionally - the alternator charging voltage is high, which converts the kinetic energy of the car electrical energy to charge the battery.

Thanks to the control of the alternator - which regulates the alternator as a function of engine performance for optimal battery charging - it is possible to reduce the voltage of the alternator at other times, eg during acceleration or driving at a constant speed . It is even possible to completely turn off the alternator. This reduces the load on the engine and improves fuel economy. Special software for managing energy and modify the software driver is required to use motor regeneration.

The new umbrella brand BlueMotionTechnologies

Volkswagen Polo introduced the concept car in Geneva under the new umbrella brand "BlueMotionTechnologies. This label refers to all the production-or nearly mature production technologies and products that significantly reduce fuel consumption and CO2 emissions. These are new developments, such as start-stop and regenerative braking system used in the Volkswagen Polo BlueMotion Concept and the highly innovative SCR catalyst in the Passat CC BlueTDI also appear for the first time in Geneva. However, it also includes the NOx storage catalytic converter that has already been successfully introduced in the U.S., and hybrid-electric drive systems, and innovative engine systems such as the Touran TSI is EcoFuel debut at the Geneva Motor Show 2009. A launching point for these extremely fuel efficient and low-emission products was the Volkswagen Polo BlueMotion, which in 2006 was the first five places for fuel consumption to 3.8 liters per 100 kilometers. The Volkswagen Polo BlueMotion Concept car far exceeds the record value of 0.5 liters.

The range of BlueMotion models available today and includes the set VW Golf, Jetta, Caddy, Touran, Sharan, Passat and Passat and Wagon. A recent survey by the organization "DAT Deutsche Automobil Treuhand", the famous and world's oldest institution of market research for the automobile, only demonstrates the success of the BlueMotion label has become today. In a representative survey, the highly respected DAT found that 85 percent of German car drivers are familiar with the BlueMotion label. The next best competitor reached only a level of recognition of 36 percent. This makes the BlueMotion number between 1 ecolabels car.
