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 teases Qs Inspiration electrified sedan concept for Auto Shanghai

Infiniti has the third installment of its Q concept lineup ready for Auto Shanghai in a couple of weeks. The 2018 Detroit Auto Show saw the Q Inspiration concept, a slinky pearlescent sports sedan. This year's Detroit show welcomed the QX Inspiration concept, an ivory electric crossover that previewed a future product. The Shanghai debut blends the two with the Qs Inspiration concept, "an electrified sports sedan for the future," that previews a forthcoming product. The Qs Inspiration appears to pick up where the 2018 Q Inspiration left off. We noted last year's show car didn't have visible tailpipes, and we suspected an electric powertrain. That wasn't the case — Infiniti said the brand's VC-Turbo technology powered the four-door. This new Qs Inspiration is built on an "all-new flexible architecture developed specifically for electrified powertrains." That's a curious distinction if by electrified Infiniti means an electrically assisted ICE. If a car needs all the paraphernalia of an ICE drivetrain, where's the electric leap? It must be somewhere, because Infiniti says the Qs Inspiration is as groundbreaking as the Q45 sedan that birthed the brand in 1989. Company boss Christian Meunier said, "Electrification creates a range of new possibilities for sedans," the concept "letting us imagine how this type of car could be reinvigorated and adapted to fit the changing needs and tastes of drivers." The teaser tells us nothing but to expect more white. There will be an "electrified form language" outside, a "minimalist cabin" inside. The dual-zone interior contains a "clutter-free cockpit ... to engage the driver, and a relaxed passenger zone that make the most of the generous interior space." Naturally, there'll be more Japanese "artistry and craftsmanship" than you can process in one sitting. Stay tuned April 16 for the reveal.

Final Recap: Days 2 and 3 notes, quotes, and takeaways from the US Grand Prix

The Texas grass no longer rustles with 2.4-liter V8 exhaust blown at 18,000 revs, the Texas dust is no longer raised by hard-compound Pirellis. We saw a lot and learned a lot while we were there as guests of Infiniti, and after our Day 1 and race recaps, here are the bits left over from our time spent with the carmaker and Red Bull Racing, including thoughts on a "wicked" race, Christian Horner's quest for a more level playing field, Infiniti "going longer and deeper," and why Mario Andretti should get a police escort at the beginning of a race but not a microphone at the end...
