In a piece of very investigative journalism (pun intended) Inside Line found out what Audi fans knew since long time and which is no surprise at all. The next-generation will also feature a V6 engine, read: 3.0 TFSI from Audi S4, instead of the current V8.
In what will become a sweeping change for Audi’s top-trim cars, the next S5 will have a V6 instead of a V8 engine when it comes out in 2009. An Audi source in Germany tells Inside Line that, in keeping with the recently launched Audi S4, the S5 will get the new 329-horsepower supercharged V6 engine that is on call to replace the age-old 4.2-liter V8. The V8 was used in the previous S4 as well other high-line Audi models.
“Not only does this new engine get nearly the same horsepower and more torque,” said an Audi spokesperson, “but the fuel efficiency with the V6T improves by 30 percent over the V8.” The current S5 has been given lukewarm reviews at best for its power and torque curves, not to mention its weight. The much lighter V6T engine can be expected to be a big improvement in those areas.
