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 Q30 spied again

The Infiniti Q30 is back in the news thanks to the imminent debut of the QX30 Concept as its crossover counterpart at the upcoming 2015 Geneva Motor Show. The siblings are Infiniti's entrants into the popular premium compact ranks, and the standard hatchback was recently spotted in Europe with the least amount of concealment yet. Granted, this tester is still pretty heavy camouflaged, but this is a lot better aesthetically than the previous garbage-bag-covered look. While the pattern makes specifics hard to discern, the translation from the motor show stand to the road appears to be leaving the Q30 Concept's styling largely intact. Up front, the squinting headlights and swollen-rectangle shape of the grille remain similar, and while they are pretty hard to spot, the slashes down the side are faintly visible from some angles. The rear hews even closer to the original design with a comparable shape for the taillights and hatch, but exhausts are much smaller on this test car. Underneath the skin, the Q30 reportedly shares its platform with the Mercedes-Benz GLA-Class, and the engine is also expected to be the 2.0-liter turbocharged four-cylinder available in Mercedes' compact lineup. Official details should start spilling out soon, though, because Infiniti wants production of the hatchback to begin in 2015 at the Sunderland plant in the UK. A launch for the US market is expected in 2016. Featured Gallery Infiniti Q30 Spy Shots Image Credit: CarPix Spy Photos Infiniti Hatchback Luxury infiniti q30 infiniti q30 concept

2014 Infiniti Q50, Lexus IS 250 fail to achieve Consumer Reports 'Recommended' rating

Infiniti and Lexus might be a little concerned now that both of their new luxury sedans, the Q50 and IS250, were unable to net Consumer Reports vaunted "Recommended" rating during their first year on the market. In fact, not only did the two fail to earn a "Recommended" rating, they finished behind the vast majority of the competition after testing, including the BMW 328i, Mercedes-Benz C250, Lincoln MKZ and Volvo S60 T5.
The Q50 managed to snag a "Very Good" rating overall, but CR criticized it's road manners for not being as thrilling as the car it (sort of) replaces, the G37. The mag called the handling mundane and the steering dull, while also remarking on the poor controls. According to CR, the interior quality is "nothing special." Shade was also thrown at the Q50's reportedly poor ride.
Compared to the IS, though, the Q50 got off easy. CR called it "neither sporty nor luxurious," while criticizing the 2.5-liter V6's lack of oomph and poor fuel economy. The mag then went on to lambaste the IS's handling, steering, interior, cabin space and infotainment system.
