The 2013 Audi S7 is powered by a 420-hp brand new twin-turbocharged 4.0-liter V-8 that will rocket the car to 60 MPH.
What makes the engine special is a pair of twin-scroll turbochargers and an indirect intercooler all located in the V between the cylinder heads. The new V8 was built specifically to use the twin turbocharging system. The indirect intercooler works by cooling the fluid before it gets to the intercooler (rather than while it passes through the intercooler) from small coolers located behind the lower corners of the front bumper. This way, the intercooler can sit a few inches away from where it assists cooling the air.
The entire engines is built like this. Attention to detail and smart packaging make this V8 very compact (no longer than many V6s) efficient and ridiculous power. All this while maintaining a fairly low carbon footprint.
In this first drive video review Nathan has chance to drive and test this new Audi hatchback in LA California to see if the new S7 bite is as ferocious as it’s bark.
Check it out as Nathan put the new Audi S7 to the TFLcar test.
