Since you are concern about a 'sporty, quick luxurious car', first of all we should omit The Macan, X5 & ML c'se comparing to the remaining two (RR Sport & Cayenne) those cars are not up to compete these two in sport, quick or luxury.

Now out of Sport & Cayenne, the Cayenne's top end variant 'Turbo S' is truly a monster when it comes to power. It can cruise 0-100 in just 4.5 sec with a massive torque of 750nm along with a 550hp of power the engine generates & while coming into the RRS, the top end variant 'RR Sport Autobiography' offers more of a sporty & luxury effect rather than power. Still it can cruise 0-100 in just 5.3 sec at a torque of 624nm & 510hp plus a 5.0ltr V8 engine compared to Cayenne's 4.8ltr V8.

Both are pricing in the range of 6la though.

But IMO there is one more macho SUV that suits all your needs. It’s sporty, it’s quick & almost a luxury SUV at just a half of the price of an Sport or a Cayenne. “The 2014 Grand Cherokee SRT” it is, one of the most aggressive-looking SUV on the market. Its 6.4l Hemi powered V8 engine is simply outstanding. Once you kick the throttle down the music it generates through the dual exhaust is quite enough to understand what an SRT is all about, you know. It can touch the 0-100 needle in just 5 seconds at a 630nm torque and 465bhp. Also the pricing is the most important factor, you can get one for just 2.5la now. Almost half of the money you can save in compare to RRS & Cayenne. Moreover you can stand apart from the over crowded RR Sport & Cayennes on Qatar tarmacs as well.

Sit back, think & go for a test drive…All the best.
