2014 Infiniti Q50 debuts G-replacing design, new hybrid model

Feast your eyes upon the all-new 2014 Infiniti Q50. Say what you will about Infiniti's new Q and QX naming system, but after looking at the new Q50 unveiled today at the Detroit Auto Show and checking out its feature list, we're having a hard time coming up with any additional criticisms. The highlights of the Q50, which goes on sale this summer in the US, include the eye-catching design, innovative cabin technology and a fuel-efficient hybrid model.
The Infiniti G has always had a focus on leading-edge styling, and its replacement is no different. We can easily see that the basic theme of the Q50 was inspired by the Infiniti LE Concept we saw earlier in the year. The edges are a little toned down for the production design, but the overall look is there with the fluidic lines, crescent-shaped C-pillar, the now-signature grille and the horizontal headlights and taillights. Compared to the current G Sedan, the Q50 is longer, wider and lower than its predecessor, and it's also more aerodynamic with a drag coefficient of just 0.26, putting in between the Chevrolet Volt (0.28) and the Toyota Prius (0.25).

NHTSA opens investigation into Nissan's handling of airbag recall

In March of 2014, Nissan recalled eight models among its Nissan and Infiniti brands, totaling more than one million vehicles, over faulty occupant classification system software controlling the passenger airbag. The company discovered a variety of factors that would interfere with the system's ability to detect an adult passenger in the shotgun seat, resulting in an illuminated warning on on the dashboard and the passenger airbag not deploying in an accident. Yet 124 complaints submitted to the National Highway Traffic Safety Administration since the recall allege that the dealer-installed fix hasn't actually fixed the problem; some consumers say the problem persists after multiple trips to the dealer. The Detroit News reports that NHTSA is opening an investigation into the matter to determine whether a new recall is needed. The occupant sensor has been a bugbear for Nissan over the past couple of years; a much smaller recall for the issue in 2013 covered five of the eight vehicles that were recalled in 2014, and that earlier recall also continued to generate complaints after the issue had supposedly been fixed. At the same time, the company learned that in two instances there was another twist, where the dashboard warning wasn't illuminated but the passenger airbag still didn't go off in an accident. Nissan isn't alone, though, with airbag recalls on a steep upswing across the industry even before the Takata debacle.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
