When it comes to straight line performance, the Porsche Macan Turbo definitely holds all the bragging rights in the face of its Audi SQ5 rival. But which one makes more of a racket?
Their engines aren’t all that different. Both of these fast compact premium SUVs have petrol-powered V6 units, although the 3.6-liter twin turbo one in the Macan is good for 400 PS (394 HP), whereas the SQ5’s 3.0-liter TFSI is rated at 354 PS (350 HP).

At idle, both cars produce a nice low rumble, though nothing spectacular – just enough to let you know you’re not listening to the base models.Get more lively with the throttle and the Macan Turbo will growl a little more heavily than the SQ5, letting off a few crackles, but otherwise the soundtracks can be described as comparable.They even sound alike on the move, although if this was a performance comparison, the Porsche would clearly ace it thanks to its faster acceleration and higher top speed.
