# Air-Fueled Cars The Peugeot 208 Hybrid 2L Car Has a Gasoline-Air Powertrain By Rahul Kalvapalle | Published 2014-09-16 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/peugeot-208-hybrid References: [gizmag](http://www.gizmag.com/peugeot-2014-hybrid-air-demonstrator/33808/) & [peugeot](http://www.peugeot.com/en/products-services/cars/new-peugeot-108) The [Peugeot](https://www.trendhunter.com/trends/peugeot-e3008) 208 Hybrid is a demonstrator car that is fitted with a gasoline-air powertrain. It offers a fuel economy of 2 liters per 100 km. The Peugeot 208 Hybrid's Hybrid Air powertrain brings together a 1.2-liter [gasoline engine with a compressed-air drive](https://www.trendhunter.com/trends/offroad-vehicles1). The car carries a comprssed air tank below the trunk, and has a low-pressure expansion tank mounted right by the rear axle. The compressed air works with a hydraulic motor system to power the car. The car has a [zero-emissions 'Air mode'](https://www.trendhunter.com/trends/renault-twingo-etech-electric-prototype) for low-speed urban driving, a 'petrol mode' for highway driving and a Combined mode. The car was built around the 82-horsepower 1.2-liter PureTech 208 five-seater car. The car's carbon composite body panels and coil springs were swapped out. The exhaust system's stainless steel was thinned out to provide a 20% weight reduction, helping slice the vehicle's down by 100 kg. ## Trend Insights (Trend Hunter) - Score: 2.3/10 - Popularity: 33% | Activity: 28% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### Why This Trend Is Growing - **Gasoline-air Powertrain:** Developing hybrid vehicles that combine gasoline engines with compressed-air drive for improved fuel economy and reduced emissions. - **Low-pressure Expansion Tank:** Implementing low-pressure expansion tanks in vehicles to enhance energy efficiency and power generation through compressed air and hydraulic motor systems. - **Zero-emissions Air Mode:** Integrating zero-emissions 'Air mode' in cars for low-speed urban driving, offering environmentally friendly transportation options. ### Industries Being Reshaped - **Automotive:** The automotive industry can leverage gasoline-air powertrains and low-pressure expansion tanks to develop more sustainable and eco-friendly vehicles. - **Energy Storage:** The energy storage industry can explore the use of low-pressure expansion tanks and hydraulic motor systems to store and release energy efficiently. - **Sustainable Transport:** The sustainable transport sector can promote and implement zero-emissions 'Air mode' in vehicles to reduce air pollution and promote cleaner urban mobility. ## Related on Trend Hunter - [Gasoline-Producing Prototype Devices](https://www.trendhunter.com/trends/aircela.md) - [Hydrogen-Powered Supercar Teasers](https://www.trendhunter.com/trends/alpine-a4810.md) - [Air-Powered Racer Toys](https://www.trendhunter.com/trends/airpower-turbo-racer.md) - [Omni-Fuel Vehicle Concepts](https://www.trendhunter.com/trends/andrietta-concept-car.md) - [Hydrogen-Electric Racecars](https://www.trendhunter.com/trends/missionh24.md) - [Hydrogen Fuel-Cell Engines](https://www.trendhunter.com/trends/airbus.md) - [Traditional Vehicle Hydrogen Concepts](https://www.trendhunter.com/trends/corolla-cross-hydrogen-concept.md) - [Hydrogen-Powered Hypercar Concepts](https://www.trendhunter.com/trends/alpenglow-hypercar.md) - [Dual-Motor Quick-Charge SUVs](https://www.trendhunter.com/trends/peugeot-e3008.md)
