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.

2015 Infiniti Q70L

A quick look at a scatter plot that charts rear legroom against luxury sedan MSRPs reveals a dearth of spacious bargains - few, if any, luxury sedans offer exceptionally spacious rear accommodations at a relatively low starting price. To fill the vacuum, Infiniti has made its Q70 available in a Q70L variant - in English, long wheelbase - for 2015.
The artist formerly known as the Infiniti M has been available in stretched-out form in the Chinese market for two years, and the US introduction is accompanied by several updates that include slightly reworked styling cues, and refinements to the drivetrain and chassis. The Q70L's wheelbase extends 5.9 inches (with a commensurate expansion of knee room), while overall length increases to 202 inches, a 7.3-inch bump. Powertrain options include a 3.7-liter V6 which produces 330 horsepower and 270 pound-feet of torque (starting at $51,350), or a 5.6-liter V8 that yields 420 hp and 417 lb-ft (and climbs to $64,550). The long-wheelbase treatment adds $1,500 to Q70 MSRPs. Not surprisingly, the Hybrid version is not available with the L treatment.
Up to three Q70L rear passengers are treated to reading lamps, a 12-volt power outlet, rear door close assist, and available heated seats. Unlike its Far Eastern counterpart (and competitors like the $61,500 Hyundai Equus), the US-spec Q70L's rear seats don't recline. Bummer.

Nissan recalls 640k crossovers for wiring issue, hood release

The National Highway Traffic Safety Administration has announced two separate recalls affecting hundreds of thousands of Nissan crossovers. The larger of the two involves the electrical system in 2008-2013 model year Rogue CUVs. In affected vehicles, a mixture of moisture and salt seeping in through the carpet on the driver's side could cause the harness connector to short, potentially causing a fire. The issue involves Nissan Rogues manufactured between March 7, 2007, and November 26, 2013, as well as examples of the 2014 Rogue Select manufactured between September 23, 2013, and July 2, 2014. All told, that comes to an estimated 468,815 units in the United States alone. The second recall affects the relatively smaller quantity of 170,665 vehicles, made up of 2013-14 Nissan Pathfinder, 2014 Pathfinder Hybrid, 2013 Infiniti JX35, 2014 QX60 and 2014 QX60 Hybrid models. (The JX35 was recently relabeled as the QX60 under Infiniti's new nomenclature.) The issue affecting some of those vehicles revolves around a hood release cable that may not properly latch. Nissan is notifying owners of the affected units to bring their vehicles in to have the wiring checked and to replace the harness connector and seal in the former case, and to have the hood release mechanism modified in the latter. All told, an estimated 639,480 vehicles are being recalled as part of the two campaigns. RECALL Subject : Electrical Short Due to Water Seepage Report Receipt Date: JAN 26, 2015 NHTSA Campaign Number: 15V032000 Component(s): ELECTRICAL SYSTEM Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008-2013 Nissan Rogue vehicles manufactured March 7, 2007, to November 26, 2013, and 2014 Nissan Rogue Select vehicles manufactured September 23, 2013, to July 2, 2014. The affected vehicles may experience an electrical short in the harness connector due to a mixture of snow/water and salt seeping through the carpet on the driver side floor near the harness connector. CONSEQUENCE: An electrical short can cause a vehicle fire. REMEDY: Nissan will notify owners, and dealers will inspect the kick panel wiring harness connector and will if necessary install a new harness connector and waterproof seal, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Nissan customer service at 1-800-647-7261.
