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 yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.

2022 Infiniti QX55 First Drive Review | A gorgeous value

Looking at the luxury crossover market, you can probably guess that there’s a clear demand for fastback variants. All the German automakers offer multiple coupe-like crossovers. The rest of the industry hasn't been so sure, including Infiniti, which didn't originally plan to offer a rakish version of its QX50. Yet here is the 2022 Infiniti QX55, and it's the direct result of customer demand. The people wanted it, so Infiniti brought it.   The company didnÂ’t just stop with the low, curvy roofline, though. The front fascia features a wavy, almost sculptural grille, a deeper chin spoiler and crisp black accents around the outboard grilles. The rear gets wider taillights with pronounced LED segments and a diffuser between the tailpipes. The license plate has been moved to the bumper, too, so that you get a big Infiniti badge and proud brand lettering across the hatch. On top of that, every QX55 gets big 20-inch wheels. These detail changes, plus the new roof make this not only a much more attractive-looking iteration of the QX50 but also arguably the best-looking crossover “coupe” in the segment. InfinitiÂ’s flowing design language naturally complements the QX55Â’s shape, and it looks almost like it was designed to be this way in the first place, whereas competitorÂ’s SUV coupes tend to look like afterthoughts. Mechanically, the QX55 is nearly identical to its boxier QX50 sibling. The only main distinctions are that the QX55 comes with all-wheel drive as standard, and the new body actually improved chassis rigidity by 10%. The engine is the same turbocharged, variable-compression 2.0-liter four-cylinder from the QX50 making the same 268 horsepower and 280 pound-feet of torque. Fuel economy is also identical at 22 mpg city, 28 mpg highway and 25 mpg combined. Power goes through a CVT, which again, is basically the same as the QX50Â’s. ItÂ’s not the smoothest engine in the segment, but itÂ’s a responsive and playful one, delivering great low-end torque. The CVT is smooth and reacts quickly to acceleration demands. It has a manual mode that works decently, too, but you never have full manual control. So you might as well let it do things automatically, which is no bad thing. As for the ride and handling, the QX55, even with its extra rigidity, feels just like the QX50. It has a soft, plush ride and an extremely quiet cabin befitting a luxury car. But when itÂ’s time to corner, itÂ’s deeply disappointing. ThereÂ’s lots of body roll and understeer.
