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.

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

NHTSA opens investigation into Nissan's handling of airbag recall

In March of 2014, Nissan recalled eight models among its Nissan and Infiniti brands, totaling more than one million vehicles, over faulty occupant classification system software controlling the passenger airbag. The company discovered a variety of factors that would interfere with the system's ability to detect an adult passenger in the shotgun seat, resulting in an illuminated warning on on the dashboard and the passenger airbag not deploying in an accident. Yet 124 complaints submitted to the National Highway Traffic Safety Administration since the recall allege that the dealer-installed fix hasn't actually fixed the problem; some consumers say the problem persists after multiple trips to the dealer. The Detroit News reports that NHTSA is opening an investigation into the matter to determine whether a new recall is needed. The occupant sensor has been a bugbear for Nissan over the past couple of years; a much smaller recall for the issue in 2013 covered five of the eight vehicles that were recalled in 2014, and that earlier recall also continued to generate complaints after the issue had supposedly been fixed. At the same time, the company learned that in two instances there was another twist, where the dashboard warning wasn't illuminated but the passenger airbag still didn't go off in an accident. Nissan isn't alone, though, with airbag recalls on a steep upswing across the industry even before the Takata debacle.
