You probably already know this, but for those who may have missed that class, Infiniti is Nissan's luxury division, just as Lexus is Toyota's prestige sub-brand. But don't look at Infiniti as just a fancy Nissan. No, look at it as a really, really fancy Nissan.

Actually, that's not fair, because while Infiniti sure does share many of Nissan's things such as gearboxes, vehicle platforms and office space in downtown Atsugi, Japan, there's a lot of Infiniti in Infiniti. Take the Q60 Red Sport which we drove for the first time on Australian roads. This is a car which not only has technology which isn't found in any Nissan but is a world first for any car, and that's just the start. More on that later.

The Q60 Red Sport has two doors, is rear-wheel drive and wants to be considered a worthy opponent for the Audi S5 Coupe, BMW 440i, and Mercedes-AMG C43, but if we're all honest with each other, its direct rival is the Lexus RC 350. Just think of Infiniti as the mysterious premium economy nether region between everyday Toyotas and Nissans and the high-end Mercs and Beemers.

The Red Sport is the top of the Q60 range and it's finally landed in Australia, five months after the other two grades in the line-up touched down here. Those were the GT and Sport Premium, and neither set our world on fire at the time.

So going to the Red Sport launch felt like we were heading off to the last movie in a trilogy without enormous expectations. That would only serve to make the Red Sport's impact on me even more impressive.
