Vehicles like the Mercedes-AMG GT uses a V8 with turbochargers inside the V of the engine. Here’s why it’s better.
In a bit to increase efficiency and performance, some car manufacturers have implemented a “hot V” setup in in their engines, putting the turbochargers for their V-shaped blocks between the cylinders rather than on the outside. But how exactly does that improve the engine? Well, it’s just all about packaging.
As Jason Fenske of Engineering Explained tells us, putting the turbocharger and its associated piping inside the V saves an enormous amount of space when compared to a normal turbocharger arrangements. Since there’s no snails hanging off the side of the engine, there’s a lot more freedom to put the powertrain within the car. Additionally, the amount of distance the charged air and exhaust energy have to travel is greatly reduced, meaning the turbocharger will spool quicker.
Cooling is better off as well since the hot V setup separates the warm and cool parts of the turbo system. The way it’s set up, the turbochargers and hot exhaust are at the top rear part of the engine, while the intake and charged air are left at the front and either side.
That’s just a simple explanation. Watch the whole video to see how it operates.
