2025 Audi SQ7 55 TFSI

4.0 TFSI

Twin-Turbo V8

A deep, hard-hitting twin-turbo V8 with a vast torque plateau from low revs, delivering relentless, refined thrust that defines Audi's S and RS flagships.

Audi's 90-degree 'hot-vee' V8 with both turbochargers nestled inside the cylinder banks; Audi was the last of Germany's big three to field a downsized twin-turbo V8, arriving after BMW's S63 and Mercedes' 5.5-liter.

• The 'hot-vee' layout places the turbochargers in the V's valley, shortening the path from exhaust port to turbine for sharper response.
• The same engine family powers Audi's hottest RS6, RS7, RS Q7 and RS Q8 in a higher state of tune.
• Arriving last let Audi study its rivals' V8s before launch, yielding an unusually punchy unit from the outset.
