The Infiniti QX50 is the Infiniti model formerly known as Infiniti EX. And, while you will see many bits of marketing hype touting the all-new Infiniti QX50, the only thing all-new about the model is its name. Going into the 2014 model year, all Infiniti nomenclatures will begin with the letter Q, because a simple alphanumeric nomenclature system wasn’t confusing enough for the Tennessee-based sub-brand of the Japanese car company owned by a French conglomerate.

Seriously though, why the nomenclature changes?

Thus saith Johan de Nysschen, president of Infiniti Motor Company Limited...

“We are embarking on a massive product offensive, and these new cars will need names. There are no suitable combinations of Alphanumeric naming options remaining, which are not already trademarked by another automaker. In order to expand our line up with the fascinating new models we are developing, we must create a more flexible nomenclature philosophy.

Further, our new advanced technology engines under development will be smaller, lighter, and more fuel efficient—yet more powerful. It would be a bit odd to have a powerful, luxurious, and refined V8 powered Infiniti M56, then position a new high-tech 550+ horsepower performance flagship for the Infiniti M range above it, using a potent charged induction V6, but then call it Infiniti M30, which we would be obliged to do, following our current naming logic”.

So, long story short, Infiniti is developing new smaller, but more powerful engines and so positioning its models based on engine displacement will no longer make sense. It’s a bit confusing now, but eventually it will all make sense.

That said, the Infiniti EX37, now known as the Infiniti QX50, is essentially an Infiniti G37, no, wait, Infiniti Q50 (which is what the G37 shall henceforth be known as) station wagon. The two models use the exact same platform, albeit with a different body. The good news is, like the G37, (Ack! The Q50!!!) The QX50 is blessed with near 50/50 weight distribution, a smooth and powerful V6 engine, and a supple suspension system capable of delivering both a comfortable ride and dynamic handling. Other hallmarks of the model are its luxurious interior treatments and loads of tech gear.

Of course, had Infiniti dared refer to the model as a station wagon, sales would have been positively dismal. So they called the EX (now QX) a crossover SUV instead.  That said, the Infiniti QX50 is a five-passenger, rear- or all-wheel drive model powered by a 325-horsepower V6 engine displacing 3.7-liters and producing 267 ft-lbs of torque. A seven-speed automatic transmission is standard equipment.
