Rivals? The BMW X5M offers brutal performance in a similar-sized package, but asks for a fair bit more than the Porsche with its $212,900 sticker price.
Closer to home, the Audi SQ7 at $162,500 is more affordable than the GTS, but its 4.0-litre turbo V8 is diesel-powered and that might not resonate so well with some buyers.
Staying in the Audi garage, the RS Q8 is powered by the same 4.0-litre twin-turbo V8 as found in the Cayenne GTS, albeit with a more aggressive tune and a faster 0–100km/h time. But, it’s also more expensive at $208,500. Those tenths-of-a-second don’t come cheap.
