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.

Infiniti EV delayed to add better tech

An evolution in lithium-ion batteries and "interesting advances in electric technology" are said to be responsible for the delay of Infiniti's electric car, the production version of the LE concept first shown at the New York Auto Show in 2012. At the time of its introduction, Infiniti said we'd have a version we could buy within two years; that timeline became 2015, and now Automotive News Europe reports that it's"still within in our mid-term plan" but officials aren't saying how long the delay will be.
When shown, the LE had a 24kWh lithium-ion battery and a 100kw electric motor producing 134 horsepower and 240 pound-feet of torque, a 100-mile range and the potential for wireless charging. It isn't clear if the postponement will bring improved specs or perhaps improved packaging and technology - or both. All we have for now is that the new timeframe is "not significantly" beyond the original plan.

Nissan recalling GT-R, Infiniti crossovers over steering column issue

Nissan has discovered a problem with the steering column on some of its higher-end all-wheel-drive vehicles from a few years back, and has issued a recall in conjunction with the National Highway Traffic Safety Administration to address the issue. The issue revolves around the outer tube on the steering column, which may not be perfectly round. That would put extra stress on the upper steering bearing, which could cause it to fracture, disabling the car's steering ability and potentially leading to a crash. The problem affects Nissan's flagship GT-R supercar – specifically 2009 models manufactured between March 14, 2007, and April 25, 2008) as well as an array of Infiniti crossovers: namely the 2008 EX35 and the 2008-09 FX35 and FX45. In the case of the luxury crossovers, Infiniti dealers are being instructed to replace just the steering shaft, but Nissan dealers will have to replace the entire steering column assembly on the GT-R. All told, the recall is estimated to encompass 16,973 vehicles across the United States. RECALL Subject : Steering Column Tube may be Out of Round Report Receipt Date: FEB 02, 2015 NHTSA Campaign Number: 15V054000 Component(s): STEERING Potential Number of Units Affected: 16,973 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008 Infiniti EX35 vehicles manufactured June 29, 2007, to April 25, 2008, 2009 Infiniti FX35 and FX45 vehicles manufactured October 31, 2007, to April 16, 2008, and 2009 Nissan GT-R vehicles manufactured March 14, 2007, to April 25, 2008. The steering column outer tube may not be round, resulting in extra stress being applied to the upper steering bearing. This stress may cause the bearing retainer to fracture, creating extra play in the steering wheel or a possible loss of steering. CONSEQUENCE: Extra play in the steering wheel or a loss of steering may increase the risk of a crash. REMEDY: Nissan will notify owners, and dealers will replace the steering shaft on the Infiniti EX35, FX35, and FX45 vehicles, and will replace the steering column assembly on the Nissan GT-R vehicles, free of charge. The manufacturer has not yet provided a notification schedule. Infiniti owners may contact customer service at 1-800-662-6200. Nissan owners may contact the GT-R hotline at 1-866-668-1487.
