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 QX60 and QX80 Limited, now with more chrome, Alcantara

Just ahead of the New York Auto Show, we get our first glimpse at new trims on the 2019 Infiniti QX60 and the refreshed 2019 Infiniti QX80. The Limited trim is the range topping spec for both crossovers and adds some new colors, trims and visual changes you won't find on lower-tier models. Pricing hasn't been announced, but the new models will be on sale this summer. The QX60 is Infiniti's best-selling model. The 2019 QX60 Limited has a new dark chrome finish on the grille, fog lights and door moldings. The roof rails, cross bars and rear bumper also get a darker finish. There are new 20-inch wheels that are exclusive to the Limited model. Inside, the QX60 Limited gets new trim with contrasting stitching, leather-wrapped grab handles, dark silver wood accents, quilted leather seats and door panels, and unique floor and cargo mats. Similar treatments can be found on the 2019 QX80. The Limited model gets 22-inch wheels, stainless-steel running boards, satin chrome trim and roof rails, and a unique design on the front and rear bumpers. There's also one exclusive paint color, Anthracite Gray. Inside, the QX80 Limited has a two-tone leather and Alcantara interior. It also gets some slick looking matte-silver wood trim. Other features include illuminated kick plates, puddle lights and special floor and cargo mats. Related Video: This content is hosted by a third party.

Final Recap: Days 2 and 3 notes, quotes, and takeaways from the US Grand Prix

The Texas grass no longer rustles with 2.4-liter V8 exhaust blown at 18,000 revs, the Texas dust is no longer raised by hard-compound Pirellis. We saw a lot and learned a lot while we were there as guests of Infiniti, and after our Day 1 and race recaps, here are the bits left over from our time spent with the carmaker and Red Bull Racing, including thoughts on a "wicked" race, Christian Horner's quest for a more level playing field, Infiniti "going longer and deeper," and why Mario Andretti should get a police escort at the beginning of a race but not a microphone at the end...
