A hot vee turbocharged engine (or hot V) is a V engine with one or more turbochargers in the "V" between the cylinder banks. This reverses the gas flow in the traditional layout for V engines where there is a single intake manifold in the center of the V (the "cold side"). [1] The hot vee offers a shorter air path from the turbocharger, through an intercooler, and back into the engine intake, which can reduce turbo lag. [2]
Ferrari 126C F1 car used a hot vee in 1981. [3] BMW N63 was the first production motor using the hot vee, [4] used in the US-made BMW X6 since 2008. Since then others have been introduced including the Mercedes-AMG GT (2014), [5] the Porsche Cayenne Turbo (2018) and Cadillac's twin-turbocharged 4.2 liter V8 in the 2019 CT6-V.
