Infiniti recalls Q50 and Q70 Hybrid models

Infiniti is issuing three separate recalls for its Q50 Hybrid and Q70 Hybrid and M35 Hybrid covering roughly 13,794 vehicles in North America.
The larger campaign listed by the National Highway Traffic Safety Administration covers 5,831 examples of its 2014 Q50 Hybrid (shown above) and 2014 Q70 Hybrid in North America, with 5,412 of those in the US and its territories. According to NHTSA, "due to a software error, the electric motor may stop working while the vehicle is being driven using the electric motor only," creating a "stall-like condition." To fix the fault, the company is reprogramming the motor inverter software, and owners should be contacted in mid-November.
The second recall covers just 890 2014 Q50 Hybrid and 2014 Q70 Hybrid models in North America, with 817 of those residing in the US. It's possible that their transmission housings were damaged during manufacturing, and on affected models, the housing could have a crack that might fracture while driving. Dealers will inspect the transmission and faulty examples will be replaced.

Q50 Eau Rouge to kick off series of performance Infinitis

Infiniti is desperate to position itself as a brand for performance enthusiast. It's tried to create that impression by attaching its name to the Red Bull Racing team, by sprucing up the G37 Coupe and G37 Convertible as part of its lack-luster Infiniti Performance Line, and by bringing Sebastian Vettel on board to create a special edition FX crossover. But the Japanese luxury brand knows it's going to need something more comprehensive if it's going to go up against BMW and its M models, Mercedes and its AMGs, or Audi and its Quattro GmbH-tuned RS range.
That's why the Q50 Eau Rouge concept unveiled just last week at the Detroit Auto Show was so important to the marque. But Infiniti has more in store than just a concept. Nissan desires to put the Q50 Eau Rouge - named after the notoriously challenging turn at the Spa Francorchamps circuit in Belgium - into production with a 500-horsepower engine. But in speaking to Automotive News, Infiniti chief Johan de Nysschen hinted at more good news to come.
That could include a performance version of a new flagship sedan Infiniti is said to be working on, positioned above the current Q70 to fill the void left by the discontinued Q45 that capped the brand's range before it shifted its entire naming scheme behind it. The flagship sedan would need some serious muscle to challenge the likes of the Mercedes S63 AMG and Audi S8, but Infiniti seems bent on getting there. To cap it all off, Infiniti has long been rumored to be working on a halo sports car. Whether they'll all carry the Eau Rouge name, the IPL badge or some sort of other designator remains to be seen, but we'll enjoy seeing this development progress.

2021 Infiniti Q50 Red Sport 400 Road Test | Z engine preview

There isn’t much reason to take another look at the 2021 Infiniti Q50 Red Sport 400 on the surface. ItÂ’s largely the same sedan as it was when we drove it in 2016: powerful and stylish, but lacking in tech and polish. However, whatÂ’s under the hood is of far more interest to us today than it was just a year ago. ThatÂ’s because the 3.0-liter twin-turbo V6 powering this Infiniti is migrating over to the next Nissan Z car. Nissan announced that the production Z would get a 3.0-liter twin-turbo V6 not long after it revealed the Z Proto. There are no other twin-turbo V6s in NissanÂ’s arsenal but this one, meaning that the VR30DDTT engine in this Infiniti is destined for the Z — plus, there's photo confirmation. The big question remaining is: How new or different will it be? Its most potent state of tune is rated at 400 horsepower and 350 pound-feet of torque. ThatÂ’s a high number versus most other boosted six-cylinders, and perhaps most importantly, itÂ’s more potent than the 382-horsepower 2021 Toyota GR Supra 3.0. As weÂ’ll soon explain, though, numbers only tell part of the story. Transplanting the InfinitiÂ’s V6 into the next Z surely wonÂ’t be without challenges, either. Nissan is promising a six-speed manual in the Z. Meanwhile, this engine is exclusively paired with a traditional seven-speed automatic transmission in the Q50 and Q60. Nissan hitched this engine up with a manual in a 370Z SEMA show car years ago, but now it must devise a production car solution. ThereÂ’s also the question of whether Nissan will use the same seven-speed as the automatic option in the Z, or come up with something a bit more aggressive. The cost-efficient (and likely) solution would be reusing the seven-speed, not unlike the Supra's eight-speed traditional automatic.  Having all of this in mind, we set out to see how this engine sits today as a preview to the Z.  Going from the big, naturally aspirated VQ series V6 to a smaller twin-turbo V6 will bring about the obvious changes. The rabid and uncouth personality of the outgoing VQ is nowhere to be found in the sweet and smooth new engine. ItÂ’s not quite the silky, effortless BMW inline-six found in the Supra, but it brings an air of refinement and maturity that's simply not there in the current Z. And then thereÂ’s the torque. All 350 pounds of twist are available at 1,600 rpm in the Q50 Red Sport 400, which means the shove in the back would theoretically start just off idle.
