# Ultra-Efficient Engines This New Audi Engine Uses a New Combustion Method By Rahul Kalvapalle | Published 2015-05-13 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/new-audi-engine References: [gizmag](http://www.gizmag.com/audi-high-efficiency-two-liter-engine/37428/) & [audi-mediaservices](https://www.audi-mediaservices.com/publish/ms/content/en/public/pressemitteilungen/2015/05/07/world_premiere_at.html) This new [Audi](https://www.trendhunter.com/trends/audi-a6-avant) engine uses a new and cutting-edge combustion method that gives it the title of [most efficient two-liter gasoline engine](https://www.trendhunter.com/trends/2025-subaru-forester-hybrid) in its class. The engine's combustion setup allows it to produce 190 horsepower while returning a hugely impressive 47 miles per gallon on the New European Drive Cycle. The engine also produces 236 pounds-feet of torque that's available from just 1,450 revs per minute. This new engine is set to debut in the [next-generation Audi A4](https://www.trendhunter.com/trends/audi-electric-mountain-bike) cars. It's an impressive piece of engineering in that the engine's intake time was lessened by reducing the crank angle while still allowing for optimal cylinder charges. With its impressive torque and power output, this engine is perfect for vehicles looking to switch from low speeds to surge mode to fill gaps in traffic. ## Trend Insights (Trend Hunter) - Score: 4.0/10 - Popularity: 61% | Activity: 50% | Freshness: 8% - Audience gender: 50% men, 50% 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 - **Ultra-efficient Engines:** Innovative combustion methods can lead to highly efficient car engines with impressive fuel economy and torque. - **Optimized Cylinder Charges:** Reducing crank angles can lead to faster and optimized cylinder charges in car engines, improving overall performance. - **Surge Mode Vehicles:** High-torque engines can create new opportunities for vehicles that require instant acceleration, like surge mode vehicles. ### Industries Being Reshaped - **Automotive:** Automotive manufacturers can incorporate innovative combustion methods and optimized cylinder charges in their engines to improve fuel economy and torque, attracting eco-conscious and performance-focused consumers. - **Transportation:** High-torque engines can become a game-changer in the transportation industry, especially for surge mode vehicles that require instant acceleration and deceleration. - **Engineering:** Engineers can use this new combustion method and optimized cylinder design to create more efficient engines with fewer emissions, which can be beneficial for both the automotive and transportation industries. ## Related on Trend Hunter - [Enigmatically Efficient Engines](https://www.trendhunter.com/trends/efficient-engines.md) - [Powerful All-Electric Station Wagons](https://www.trendhunter.com/trends/audi-a6-avant.md) - [Luxury Aerodynamic Sedans](https://www.trendhunter.com/trends/2026-a6-sedan.md) - [Sleekly-Designed Electric Vehicles](https://www.trendhunter.com/trends/audi-rs-etron-gt.md) - [Electrified Classic Saloon Cars](https://www.trendhunter.com/trends/saloon-car.md) - [Sophisticated High-Range EV Sedans](https://www.trendhunter.com/trends/2025-audi-a6-etron.md) - [Extra-Sporty Electric SUV Models](https://www.trendhunter.com/trends/audi-q4-40-etron.md) - [Beastly Luxury Electric SUVs](https://www.trendhunter.com/trends/audi-q4-55-etron.md) - [Efficient Performance Electric SUVs](https://www.trendhunter.com/trends/audi-q6-suv-etron-performance.md)
