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:

2024 New York International Auto Show Editors' Top 5 Picks

The New York Auto Show, like many other shows over the past few years, has shrunk. But it's still playing host to some interesting reveals, and we even got a few surprises this year. It was dominated by Nissan and Hyundai Motor Group products, but ones running the gamut from affordable cars to flagship SUVs. It was a strange situation of being both quite diverse in reveals, and not at all, depending on how you looked at it. Our favorites of the show are a clear representation of that. And another interesting observation, only one of the picks was significantly electrified. Scroll down to see the best reveals of the New York Auto Show,. 2025 Nissan Kicks View 10 Photos 5. Nissan Kicks "The Nissan Kicks has gone from a reasonably attractive and small crossover into something way more funky with cool textures, color combinations and some actual presence. Plus, it's more spacious, more powerful and has available all-wheel drive. If Nissan can keep the price nice and low to compete with similarly stylish and well-executed competition like the Chevy Trax, the company's got a real winner on its hands." – News Editor Joel Stocksdale InfinitiQX80-Z63-051 View 39 Photos 4. Infiniti QX80 "The QX80 wasn't technically shown at the New York Auto Show, but it was revealed just a week prior at Hudson Yards – accross the street, in other words. Frankly, I wasn't blown away by the initial photos, but I think it looks great in person. The attention to detail both outside and in seem appropriate for an SUV that Infiniti hopes to sell for six figures loaded up. I'm a believer." – Associate Editor Byron Hurd 2025 Kia K4 Live View 7 Photos 3. Kia K4 Sedan "The Kia K4 interior has way more style than anything in the compact car price range has any business having. Now, if we don't get the green interior option shown in the initial global reveal photos, I'm retracting several of my points here. Otherwise, wowza. I kept looking and looking at that K4 interior photo, and finding new, interesting details to admire. Oh, and the exterior is pretty cool, too, though I do prefer the hatchback in that regard." – Senior Editor, West Coast, James Riswick Genesis GV60 Magma Concept View 10 Photos 2. Genesis GV60 Magma "I am psyched to see Genesis show off a proper performance car. The “Sport” trims on its various models are sort of neat, but the Magma brand looks like the real deal.

2013 Infiniti IPL G Convertible

Infiniti rolled out the IPL version of its G37 Convertible at the Los Angeles Auto Show more than a year ago. The Infiniti Performance Line treatment logically mirrors that of the IPL G Coupe, meaning it receives both cosmetic and mechanical tweaks designed to raise the pulse of driving enthusiasts. Aside from the overstated aerodynamic styling components and huge exhaust tips, the cabin features special leather upholstery, aluminum trim and IPL badging to distinguish it from lesser siblings. Under the hood, the 3.7-liter V6 (VQ37VHR) has been recalibrated to deliver 343 horsepower - 18 more than the standard coupe - and 273 pound-feet of torque. The suspension has been upgraded with firmer spring and stabilizer bar rates, multi-piston sport brakes are fitted and 19-inch graphite-finish wheels wrapped with summer rubber are bolted on. There are only two exterior color choices (Moonlight White and Malbec Black) and two upholstery choices (Stone and IPL-exclusive Monaco Red). Everything sounds marvelous until someone reveals its as-tested $62,415 window sticker.
DRIVING NOTES
The three-section steel roof raises and lowers in a leisurely manner - give it about 30 seconds each way. While it is marvel to watch, the operation seems clunky, not fluid. Buttoned up, with all four windows closed, the cabin is comfortable. Wind noise is minimal and the front buckets coddle passengers in all the right places. While tight, those of smaller stature will find the two rear seats tolerable for short journeys (my kids never complained). Outward visibility is also very good for a convertible - no impeding B-pillar.
