Infiniti explored V8, diesel, hybrid power for Q50 Eau Rouge

Infiniti boss Johan de Nysschen "insists" the car be put into production.
Over the past few years, rumors have swirled about an Infiniti-badged, four-door version of the Nissan GT-R. Makes sense to us - Infiniti could certainly use a performance halo, and the seemingly forgotten IPL initiative hasn't exactly bore any interesting fruit. Enter the Q50 Eau Rouge, which recently debuted for a second time at the Geneva Motor Show packed with the 3.8-liter, twin-turbocharged heart of Godzilla itself.

Infiniti Qs Inspiration shows itself before Auto Shanghai

Infiniti's shown off a bit of the Qs Inspiration concept before debuting the creased contrivance at Auto Shanghai next week. The concept serves a few purposes, the first to reimagine a future for sports sedans on a planet of crossovers and SUVs. The result blends a fastback with high sides that connect low ground clearance below and an elevated seating position above. The Japanese luxury maker is all about sedans, the Qs Inspiration signaling how a carmaker watching the bottom line can maintain its interest in the passe bodystyle. The concept previews a production model, and perhaps the design language and lingo we'll see spreading through the range. We're not sure how the low floor and higher roof work out in the cabin, but Infiniti mentions a "low-mounted powertrain and potent e-AWD system." That's undoubtedly the promise of the "all-new flexible architecture developed to accommodate high-performance electrified powertrains." Production-izing for a non-electric version would mean laying in a grille for the ICE, but an electrified version would have plenty of room for batteries and e-motors. Before that retail model, it's possible we'll see Qs Inspiration cues on the Q50 and Q70 sedans. Take a long gander at the profile and the way the roof slopes, and you'll notice an elongated GT-R glasshouse profile. On top of that, before Infiniti released official photos, a few images leaked from China showing other angles of the concept. The rectangular steering wheel and massive digital dash cluster probably aren't going anywhere beyond Shanghai, but if Infiniti can bring that glass roof to production, that's a win in our book.

The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.
