Breaking the 700-HP mark.
Oh what a lovely sound.
Tuning up the Final Edition Roadster.
Twin-turbo German hammer.
A few basics lead to a lot of power.
One hellish AMG.
Sonic Motorsports-built, RENNtech-tuned.
Unleashing all sorts of hell on the dyno.
One mean bi-turbo machine.
Time to expand the trophy case.
And it’s closer than you think…
Listen to that 6.2-liter growl.
Living life a quarter-mile at a time.
Hear those turbos scream!
RENNtech gives the super coupe even more carbon fiber.
