The Porsche V4 engine is a two-liter, four-stroke, mono- turbocharged, V-4, racing engine, designed, developed, and built by German manufacturer Porsche, for their 919 Hybrid sports car prototype, between 2014 and 2017. ^{[8] [9] [10] [11]}

Background

The compact and lightweight engine was a two-litre (120 cu in) 90-degree V4 cylinder bank mid-mounted mono-turbocharged petrol engine. ^{[12] [13]} It ran at 9,000 rpm, with performance coming from a direct fuel-injection system and a single Garrett-designed turbocharger with a dual overhead camshaft. It produced approximately 500 hp (370 kW) and acted as a chassis load-bearing member. Due to the small size of the engine, the transmission casing was fitted to the rear suspension and was almost a third of the car's length. Engine air ingestion was achieved through a carbon-fiber-and-gold thermal wrapped airbox in its center. Front airflow was enabled by louvers along its flank, and a single curved roll-hoop intake was mounted on its roof to feed the carbon-fiber airbox.
