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.

Renault-Nissan debuts new Common Module Family for future vehicles

Platform sharing is nothing new for the 14-year-old Renault-Nissan Alliance, but this partnership is set to introduce new modular platform components that will eventually underpin 11 Renault models and three Nissan vehicles by 2020. Rather than being a typical platform, the Common Module Family (CMF) actually represents five segments of a platform that can be used in various applications, and one of the first vehicles to use this architecture will be the 2014 Nissan Rogue (spy shots of which are shown below) when it arrives "in late 2013."
As pictured in the image above (click to expand), CMF is composed of four chassis component, principally the front underbody, rear underbody, engine bay and cockpit as well as a common electrical system. Besides the next-gen Rogue, future Nissan models to share CMF will include the Qashqai and X-Trail, while Renault models will start using the platform next year on vehicles including the Scénic and Laguna. The CMF architecture is expected to help the Alliance reduce the parts cost of a vehicle by up to 30 percent and reduce the entry cost by up to 40 percent. The official press release with more details about CMF, and what it means for Renault-Nissan, is posted below.

Nissan Pathfinder, Infiniti JX in transmission safety probe

Nissan may be forced to recall 110,000 Pathfinder and Infiniti JX35 crossovers, due to a number of customer complaints. Consumers report suddenly losing power, with repair facilities blaming the issue on faulty transmission cooler line connections. Both the Pathfinder and JX35 use a continuously variable transmission. As of right now, the only vehicles being investigated are from model year 2013.
Nissan has been cooperating with the National Highway Traffic Safety Administration, according to a report from Reuters, and it has developed a fix for the affected vehicles. It's not clear whether this will develop into a full-blown recall, as there have been no known cases of injuries or crashes. But with a potential 110,000 vehicles prone to sudden power loss, a recall seems to be a likely outcome.
