Infiniti shows off the new Q50 engine lineup in Chicago

Infiniti has a raft of engine options it's rolling out on the Q50 sedan. We found out about most of them a couple of months ago, but they're now confirmed in all their turbocharged glory. And they'll all be showcased this week at the Chicago Auto Show. The base engine is a 2.0-liter turbo four based on a Mercedes design and built at the new joint-venture engine plant in Tennessee. The engine produces 208 horsepower and 258 pound-feet of torque and will be available in the Q50 2.0t in either rear- or all-wheel drive. If those specs strike you as familiar, they're the same that you'd find in the Mercedes CLA250 and GLA250, both of which similarly make their 4Matic traction optional, but come standard in front- (not rear-) drive form. Above the four-pot sits a new 3.0-liter twin-turbo V6 that replaces the naturally aspirated 3.7-liter unit and will be available in two states of tune. The 3.0t model offers 300 hp and 295 lb-ft, but the performance model – dubbed Q50 Red Sport 400 – cranks it up to 400 hp and 350 lb-ft. Both versions come mated to a seven-speed automatic transmission and either rear- or all-wheel drive. The fourth powertrain options carries over in the form of the Q50 Hybrid, which still pairs a naturally aspirated 3.5-liter V6 to a 50-kW electric motor for a combined output of 360 hp. So if you like your sports sedan to come with some manner of assist, the Q50 offers plenty of choices. But if you're in the atmospheric camp, we're afraid you'll have to look elsewhere.

The trifecta of new powerplants will be available beginning this spring. Joining the three new engine-equipped Q50 models – designated the Q50 2.0t, Q50 3.0t and Q50 Red Sport 400 – on display at the country's oldest and best-attended auto show are the redesigned 2016 QX60 crossover and the all-new QX30 premium active crossover.

Infiniti QX70 is fini, for now

We knew it first as the FX, debuting in 2003 as a bulgingly macho SUV/crossover thing with an impossibly long hood. It was quick and powerful, and lower-slung than typical SUVs, more like a tall wagon. Infiniti later dialed the cartoonishness of it back a few notches and started calling it the QX70. Now, the QX70 is going to take a little break, disappearing from the lineup for a few years while QX50 and QX80 redesigns are rolled out. The QX70 is sporty, with a 325-horsepower 3.7-liter V6. But it's an aging model and a bit of a slow seller - last year, Infiniti moved one-seventh as many QX70s as it did its kid-hauling cousin the QX60 - which seats more people (seven, to the QX70's five) and is less expensive. The QX70 was once popular like that, selling 30,964 as the FX in 2004. But that was long, long ago. Last year it sold 6,261. The QX70 nameplate is expected to be back in 2021 or 2022, in a redesign based on the Nissan Murano and built at Nissan's plant in Canton, Miss.

Infiniti QX Sport Inspiration Concept fits perfectly in the QX50's shoes

If there was any doubt about whether the Infiniti QX Sport Inspiration Concept is a preview of the next QX50, the official details presented at the 2016 Beijing Motor Show should erase them. The concept is smaller – a lot smaller – than the last QX70. And despite a recent update to the QX50, the brand's midsize crossover is due for a new model. We're basing that statement on dimensions. The QX Sport Inspiration Concept rides on a 110.2-inch wheelbase, and is 181.1 inches long, 74.8 inches wide, and 65 inches high. The last QX50, meanwhile, rides on a 113.4-inch wheelbase, and is 186.8 inches long, 71.0 inches wide, and 62.7 inches high. Ignore the different lengths – the concept's front and rear overhangs are remarkably short and aren't likely to translate to production – but the wheelbase, width, and most importantly the height, present a footprint that's remarkably similar to the QX50. Combine that with our assessment of the QX Sport Inspiration Concept's styling, and it's a virtual certainty that we're looking at the QX50's successor. As we said yesterday, the high beltline, tight greenhouse, long hood, and aggressive headlights are all trademarks of both the QX50 and QX70. Infiniti didn't say what kind of engine is under this concept car's hood (if there even is one – it might just be an engineless shell), but we're almost certain it's something performance-oriented. That would prove true if and when a new production QX50 is unleashed. We're betting the company will opt for the increasingly familiar setup of the new 3.0-liter, twin-turbocharged V6, a seven-speed automatic transmission, and all-wheel drive, like what you can get on the Q50 Red Sport 400 and new Q60. With 300- and 400-horsepower versions of this engine available, it could signal an introduction of a two-tier QX50 lineup. We're getting ahead of ourselves, of course. The QX Sport is still only a concept, but Infiniti's latest information dump at the 2016 Beijing Motor Show serves as even stronger evidence that its CUV lineup will grow back to four vehicles sooner rather than later.
