Volkswagen Concept BlueSport


Volkswagen defined just two objectives in the car’s development: maximum driving fun and minimal fuel consumption. And so a mid-engine sports car was implemented that makes no compromises, that aims at low weight and maximum agility right from the start. Although it is best in its class when it comes to body rigidity, the Concept BlueSport weighs in at less than 1,200 athletic kilograms. The results: performance that is more than impressive for every life situation, in addition to the cited fuel economy and emissions advantages. Low weight was attained by consistent application of lightweight construction methods (among other things, the soft top – at 27 kilograms – is the lightest in its class, and the hoods are made of aluminum), and by a body layout with crisp and compact dimensions.
Despite all of the sports car fascination included on board, it still offers a respectable level of everyday utility. In the cargo area under the front hood, for example, the Concept BlueSport can stow 112 liters of luggage; its counterpart in the rear can handle an additional 70 liters of cargo volume. Altogether that makes 182 liters – enough for working documents or an extended weekend trip for two. Also extended, by the way, are the distances between any two fuel fillups. With a fuel tank volume of 50 liters and the noted fuel economy of 42 mpg (consumption of 4.3 liters per 100 kilometers), the theoretical range is greater than 710 miles (1,150 kilometers).
Making a positive impact on the car’s range, fuel economy and emissions are two technologies that could become more and more commonplace in the future and are part of the so-called Eco mode on the Concept BlueSport: an automatic start-stop system and braking energy regeneration. The place where automatic start-stop shines is in city traffic. When the Concept BlueSport stops at a red traffic light, for example, it automatically shuts off its engine. As soon as the light turns green again, just tapping on the gas pedal is enough to start the engine lightning fast. Its entire operation is absolutely intuitive and saves up to 0.2 liters of fuel per 100 kilometers in the city. Furthermore, primarily when the Concept BlueSport is braked, energy is generated by the alternator (regeneration), which relieves the engine and further improves fuel economy.
