No, never been supercharged. The new one isn’t either.
In 2010 the first run had a 5.4L V8, quickly replaced with the 6.2L V8 that it carried until 2014 when the 1st gen of Raptors ended.
The 2017 Raptor is a 3.5L Twin Turbo.
The nice thing about Raptors are, they hold their value EXTREMELY well. I’ve had 2 and can’t wait for the 2017 to come out.
