Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:

Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.

2022 Infiniti QX60 Review | Redesigned and relevant for the first time

Previously an afterthought in its segment, the completely redesigned 2022 Infiniti QX60 is a large luxury SUV now worth considering. It's far more stylish on the outside, and it's combined with a more luxurious interior with great standard technology and convenience features. It drives much better thanks to a new transmission and sharper suspension tuning. It all adds up to a real competitor. That doesn't mean it's a class-leader, but it's well matched to similarly priced options from Acura, Lincoln, Cadillac, Volvo, Jeep and Hyundai. In fact, with a base price of just over $47,000, it's cheaper than many of the luxury-branded alternatives, and very competitive with the high-end options of mainstream brands. Its one real weakness is a lack of powertrain options. Many vehicles in this segment have at least a couple engines to choose from, including hybrid options. Infiniti offers only a single V6 option. But the affordable price point, spacious and well-appointed interior, and good driving dynamics nevertheless make it a luxury SUV you should check out.

The Infiniti QX60 is completely redesigned for 2022. You can read more about the changes in our first drive review. What are the QX60 interior and in-car technology like? Some of the biggest improvements to the QX60 are inside. The dash has a low and wide lower plane that feels modern and airy. The air vents are hidden in one wide opening in this zone, and various surfaces feature stitched upholstery. Base models feature gloss black trim, with upper trims getting aluminum or natural finish wood trim. The top Autograph trim, which is pictured in this review, combines that lovely wood trim with unique-looking quilted leather on top of the dash. All QX60s feature a 12.3-inch touchscreen infotainment system. It runs basically the same infotainment suite that you find on Nissans, and that's a good thing. It features large, easy-to-find and easy-to-press icons. It all runs quickly and smoothly and is responsive to taps. We also appreciate that climate and audio controls have dedicated controls below the air vents. The volume and climate knobs are particularly appreciated, though the touch-sensitive buttons are less so.
