# Cylinder-Deactivating Cars The Passat BlueMotion Concept Launched at the 2014 Detroit Auto Show By Janelle Savel | Published 2014-01-15 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/passat-bluemotion-concept-das-2014 References: [autoblog](http://www.autoblog.com/photos/volkswagen-passat-bluemotion-concept/) & [autoblog](http://www.autoblog.com/2014/01/08/vw-passat-bluemotion-concept-detroit-official/) [Volkswagen](https://www.trendhunter.com/trends/volkswagen-gentravel-concept) reveals its future technology in its latest line-up of [VW](https://www.trendhunter.com/trends/official-automotive-partner) Passats with the Passat BlueMotion Concept. Unveiled at the Detroit Auto Show, it boasts improved fuel economy through their cylinder deactivation. According to VW manufactures, this is the first cylinder deactivation on a four-cylinder engine. To put this into perspective, a cylinder deactivation on a four-cylinder engine isn’t as common as one on a V8 or [V12](https://www.trendhunter.com/trends/aurora-v12). For fuel efficiency, direct-injection inline-four turns off cylinders two and three when their power isn’t needed. This automatically saves fuel and reduces unwanted emission for city driving. This Passat, however, can still run on 42 miles per gallon driving on the highway with a 150 horsepower engine. ## Trend Insights (Trend Hunter) - Score: 0.7/10 - Popularity: 12% | Activity: 2% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### Key Themes Behind This Trend - **Cylinder Deactivation Technology:** The development of cylinder deactivation on four-cylinder engines provides an opportunity for automakers to improve fuel efficiency and reduce emissions. - **Improved Fuel Economy:** Enhancements in fuel efficiency through cylinder deactivation technology offer a disruptive innovation opportunity for the automotive industry. - **Reduced Emissions:** The implementation of cylinder deactivation in vehicles presents a disruptive innovation opportunity to reduce harmful emissions and improve environmental sustainability. ### Where This Applies - **Automotive:** The automotive industry can leverage cylinder deactivation technology to create more fuel-efficient and environmentally friendly vehicles. - **Engine Manufacturing:** Engine manufacturers have the opportunity to innovate and produce advanced engines that incorporate cylinder deactivation technology. - **Environmental Technology:** The environmental technology industry can benefit from developing and implementing cylinder deactivation technology to reduce emissions and promote sustainable transportation. ## Related on Trend Hunter - [Shapeshifting Interior Electric Vehicles](https://www.trendhunter.com/trends/volkswagen-gentravel-concept.md) - [Luxe All-Electric Vehicles](https://www.trendhunter.com/trends/id-aero.md) - [Aerodynamic Electric Sedans](https://www.trendhunter.com/trends/aerodynamic-electric-sedans.md) - [Revolutionary Combustion Engines](https://www.trendhunter.com/trends/combustion-engine.md) - [Efficient Dual-Motor Hybrid Cars](https://www.trendhunter.com/trends/honda-civic-ehev.md) - [All-Electric Sleek Fastback Sedans](https://www.trendhunter.com/trends/id7.md) - [Enigmatically Efficient Engines](https://www.trendhunter.com/trends/efficient-engines.md) - [Virtual Car Concepts](https://www.trendhunter.com/trends/porsche-digital-twin.md) - [Luxury Aerodynamic Sedans](https://www.trendhunter.com/trends/2026-a6-sedan.md)
