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.

Infiniti's fastback 2021 QX55 crossover shows its stylish rear end

First announced in August 2019, the Infiniti QX55 will finally make its global debut on Tuesday, November 17. Nissan's luxury division released a preview image that gives us the best look yet at the next addition to its range. The QX55 is closely related to the QX50 crossover under the sheetmetal, but it stands out from its more family-friendly sibling with a rakish, fastback-like roofline that will inevitably attract the coupe label. It will be to the QX50 what the BMW X4 is to the X3. Although we haven't seen its front fascia yet, Infiniti's preview image shows the rear end wears horizontal LED lights that stretch deep into the quarter panels, along with a roof-mounted spoiler. We were pleasantly surprised by the QX50's upmarket interior, so we're expecting a comparable degree of opulence in the QX55. It's too early to tell if Infiniti will simply copy the 50's cabin layout and paste it inside the 55, or if the latter will receive a look of its own. Similarly, technical specifications won't be published until the model's introduction. We expect that the VC Turbo four-cylinder engine, which was a finalist for the 2019 Autoblog Tech of the Year award, will appear on the roster. All-wheel drive will certainly be available, and Infiniti may offer an entry-level variant with front-wheel drive. Infiniti will present the 2021 QX55 online Tuesday during an event that will star singer Aloe Blacc. It will stream the concert-unveiling cross on its various social media platforms starting at 8:55 p.m. Eastern time, 5:55 p.m. Pacific time. Built in Mexico, the model will arrive in American showrooms in early 2021 with a base price pegged above $40,000. What's next? The QX55 will stand out as the first model released under Infiniti's Nissan-Plus strategy, which was presented as a way to cut costs and boost profits by increasing the number of components it shares with its parent company. However, leaning more heavily on Nissan will not dilute its image or its products, according to executives. Stylists are in the process of overhauling Infiniti's design language, and the brand's reboot will put a major emphasis on technology. Looking ahead, the QX will be followed by the next-generation QX60, which is tentatively due out in 2021 as a 2022 model, and by the company's first series-produced electric car. Related Video:

2019 Infiniti QX50 First Drive Review | A high-tech engine flies under the radar

Update: An Infiniti representative reached out after this review was published and noted that the "Park with Easy Steering" function of the Direct Adaptive Steering system was erroneously left engaged. Infiniti says this feature "reduces feel considerably at low speeds to aid in parking", and that the Easy Steering function will be disabled by default in customer cars unless the customer chooses to engage it. This seems to explain the issues our reviewer had with low-speed steering feel, although we've had other problematic experiences with Direct Adaptive Steering in a broader sense – not to mention the fact that the drive-by-wire system has been recalled several times to fix various issues, and also recalibrated in response to criticism. We hope to get another QX50 soon, and if so we'll compare the low-speed steering response with Easy Steering on and off. Even as manufacturers rush headlong into electrification and autonomous driving, revolutionary internal-combustion engine technologies are still being developed. Consider the Mazda Skyactiv-X Spark Controlled Combustion Ignition process, for example. But Infiniti's VC-Turbo four-cylinder engine, which makes its debut in the 2019 QX50, is truly a work of engineering fortitude. The engine realizes the long-held ambition among engine manufacturers to create a way to alter the compression ratio on the fly, a boon to both power and fuel efficiency. It's a brilliant bit of science that's, unfortunately, still in search of the right car. Don't get us wrong, the QX50 is perfectly competent — it's an exceedingly quiet and comfortable cruiser. However, it's no longer the driver-pleasing machine its predecessor was. That car, originally known as the EX35, was built atop Nissan's sporty FM platform, a front-midship, rear-wheel-drive layout putting the engine aft of the front axle line and giving the vehicle the athletic driving dynamics of a sport sedan. In fact, it was basically a G37 hatchback, and it was sold as the Skyline Crossover in Japan. A shortened FM chassis underpinned the 370Z, to put a finer point on it. For those more concerned with comfort than corners, the 2019 QX50 might actually be a more useful. It rides atop an all-new front-wheel-drive chassis, which means it's able to add more space for both passengers and cargo. It trades a heap of the old QX50's sportiness for comfort and packaging efficiency. If that sounds good to you, perhaps the new QX50 is the right crossover.
