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.

On Location: 2015 Nissan Micra Cup racecar at Mont-Tremblant

Circuit Mont-Tremblant has an almost mythical aura for North American road racers, and it was the setting for our high speed test of the 2015 Nissan Micra Cup racecar. Nestled in the Laurentian Mountains of Quebec, the course hosted Formula One races in 1968 and 1970, Trans-Am and Can-Am competition in the 1960s and '70s, and more recently a Champ Car event in 2007. In its current configuration, Mont-Tremblant has 15 turns and covers 2.65 miles of rural Quebec about 90 minutes northwest of Montreal. Put simply: It's an excellent venue to test the Micra Cup racer, which is underpinning a spec series in Canada this summer and fall. The cars are outfitted with a Nismo suspension kit, FIA-approved racing seat with a five-point harness, safety cage, upgraded brakes, modified exhaust, and Pirelli low-profile performance tires. The stock 1.6-liter four-cylinder engine with 109 horsepower mated to a five-speed manual is unchanged. It's a cool, misty day when we get behind the wheel of the Micra Cup car. Though we're nervous, Nissan is billing the Micra Cup as a series for nearly anyone, calling it the bridge between karting and more serious racing. We believe that – the Cup car is fairly easy to drive – and our instructor is helpful with tips on the gearing and setting up corners. We finish our laps feeling excited, challenged, and wanting more. As the video above shows, the car is eager to please, and it's a lot of fun to toss around an iconic track.

Nissan, Infiniti issue recall for replacement Takata air bags in older models

Nissan and Infiniti are recalling older vehicles that were repaired after collision damage to address problems with Takata replacement air bag inflators that were potentially installed. The overall campaign population is difficult for Nissan to pin down because the only vehicles impacted would be those that Nissan and Infiniti know to have been serviced with the replacement units in question. Officially, the recalled population numbers just 375, but Nissan says more than 18,000 cars could have the defective parts installed.  Drivers of 2001-2003 Nissan Maximas, 2002-2006 Nissan Sentras, 2007-2012 Nissan Versa Sedans/Hatchbacks, 2002-2003 Infiniti QX4s and 2006-2010 Infiniti M35s/M45s that had their vehicles repaired after a collision or theft should be aware that these deadly replacement parts may have been used.  "The potentially affected inflators may have been installed on vehicles after final remedy repair completion under the vehicle recalls as part of a subsequent theft or collision repair," Nissan's notice said. "Vehicles that received the subject parts prior to December 9, 2016, are not affected as they would have been subsequently included in the final remedy recalls and replaced with a final remedy driver and/or passenger air bag inflator. Nissan has identified 18,422 vehicles that may have had these parts installed during service." The air bag inflators in question were inadvertently shipped to service inventory between December 9, 2016 and November 12, 2021 — after the dangers of Takata's inflator design were known to the industry. Notices are already being mailed; owners will be asked to bring their cars in for inspection, and if defective parts are found, they will be replaced.  Related video: This content is hosted by a third party.
