As part of its proactive approach to reducing fuel consumption and emissions, Peugeot is unveiling its new Peugeot 208 HYbrid Air 2L Demonstrator at the Paris Motor Show next month. The moniker 2L refers to its estimated fuel consumption of two liters per 100 km, which is equivalent to 141mpg. The new Peugeot 208 HYbrid Air 2L Demonstrator is derived from a production version of the Peugeot 208 1.2-liter PureTech 82hp 5-seater Hatchback.
To allow the new model to attain such a level of fuel economy, Peugeot and its project partners employed technologies typically found in competition and luxury models. For instance, the new Peugeot 208 HYbrid Air 2L Demonstrator – at just 860 kg – is around 100 kg lighter the production car, thanks to the employment of steel, aluminum and composites.
Engineers made sure that the only materials compatible with current production facilities and a high manufacturing output are chosen for the new concept. This process could reduce fuel consumption without having to tweak the car's attributes, allowing the concept to feature a high-end style.
Peugeot used carbon composites for the body panels, doors, sides, and roof. The carmaker also used carbon composites on the coil springs, thereby reducing their unsprung weight and ultimately improving dynamic handling. The French company also fine-tuned the aerodynamics of the concept, making a number of improvements -- like employing a lower stance on the road -- to reduce drag.
In addition to using new materials, the carmaker also redesigned existing part to further cut weight. For instance, Peugeot changed the thickness of the stainless steel exhaust system, making it lighter by 20 percent.
On this application, Peugeot replaced the standard powertrain with a hybrid drive system -- HYbrid Air technology -- that uses a mix of petrol and compressed air as energy source; thereby achieving greater efficiency levels according to the driving condition. Compressed air could assist and even replace the petrol engine to deliver optimal efficiency during acceleration and starts.
The HYbrid Air system includes a compressed-air tank below the boot, a low-pressure tank proximate to the rear axle serving as an expansion chamber, and a hydraulic system consisting of a motor and a pump in the engine bay. This hydraulic system features bespoke epicyclic transmission to deliver a perfect balance between the two energy sources, thereby replacing the manual gearbox while enabling automatic shifting.
During Air (ZEV) mode, the new Peugeot 208 HYbrid Air 2L Demonstrator exclusively runs on compressed air, which means it doesn’t consume fuel and emits no carbon dioxide. During Petrol mode, the new Peugeot 208 HYbrid Air 2L Demonstrator only runs on the 1.2-liter petrol engine. This is more suitable for travelling at a steady speed on main roads and motorways. The Combined mode is designed for transition phases in urban environments, such as standing starts and acceleration. It draws on the two energy sources in proportions adjusted to achieve optimal fuel consumption.
The system recharges the compressed-air tank while braking and while taking the foot off the pedal. The energy from the three-cylinder petrol engine also helps compress the air. Either way, maximum pressure is achieved in just 10 seconds.
The Peugeot Brand traces its roots to 1810, and started automobile production in 1889. The brand is celebrating 125 years of vehicle production in 2014, selling over 60 million units in this period.
As communicated via its brand signature ‘Motion & Emotion’, Peugeot is making its presence felt in 160 countries through around 10,000 Franchised Dealers. In 2013, the French carmaker sold around 1.5 million vehicles around world, and is well represented in the majority of global markets. Peugeot has weighted average emissions of 111.2 grams of carbon dioxide per km. Peugeot offers a bolstered range of products and services that deliver a refined design and a distinct driving experience.
