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.

How Renault, Fiat Chrysler, and yes, Nissan, could save through sharing

If French automaker Renault green-lights a proposed merger with Fiat Chrysler Automobiles, the companies almost immediately could begin saving money by consolidating components and basic structures on many of their most popular vehicles, an industry analyst said on Tuesday. The synergies could multiply if they invite Japanese automaker Nissan, currently Renault's alliance partner, to join the merger, according to a former Renault and Nissan executive. Renault and Italian-American rival Fiat Chrysler Automobiles are in talks to tackle the costs of far-reaching technological and regulatory changes by creating the world's third-biggest automaker. A Renault-Fiat Chrysler combination "would mean a greater sharing of parts (which) could really boost the profitability of Fiat Chrysler's smaller vehicles," said Sam Fiorani, vice president, AutoForecast Solutions. Building similar models on a common vehicle architecture, Fiorani said, "would give both companies a lot more freedom in manufacturing. They could mix brands and vehicle sizes on the same assembly line, switch vehicles between plants to balance production, and even shift production from one country to another, depending on changes in demand, tariffs or other considerations." Fiorani said Fiat Chrysler could benefit from sharing the French automaker's expertise in electric vehicles and powertrains, where Renault and Nissan have jointly invested more than $5 billion. These are areas in which Fiat Chrysler has little in the way of components or intellectual property. Another sector that is ripe for consolidation is light commercial vehicles, where Renault and Fiat Chrysler could build a variety of vans in several sizes on common platforms that could be assembled and sold in global markets. Ford Motor Co and Volkswagen AG began their alliance discussions a year ago by focusing on potential collaboration in light commercial vehicles. Getting Nissan's blessing Fiorani said Renault's CMF architecture, which was jointly developed with Nissan and underpins many of Renault's passenger cars and crossovers, could be used by Fiat Chrysler on a wide variety of vehicles. As an example, he said the CMF could provide a new single foundation for at least five Jeep models, including the Renegade, Compass and Cherokee, which now are based on four different platforms.

Nissan's Le Mans-bound ZEOD RC electric racecar nearing completion [w/video]

Nissan is working away on its ZEOD RC (Zero Emission On Demand Racing Car) which is still on pace for a Le Mans arrival in 2014. As of right now, the DeltaWing-shaped car's carbon-fiber tub and chassis have been completed. The next step will be installing the twin electric motors and fitting the seat of driver and GT Academy winner Lucas Ordóñez. If the current schedule sticks, the zero-emissions racer will hit a UK track for test laps in September.
But while those initial shakedown laps will be under full electric power, it's unclear whether the setup fielded in the UK will survive until Le Mans. Nissan itself says that it will be testing a number of "electrified" drivetrains ahead of the 2014 24 Hours of Le Mans, which is a significant departure from race car design - usually, the teams know what's powering their car before they start building it.
"Just developing a single powertrain option in only 12 months would be a mammoth task but we're looking to carefully examine a number of options to ascertain which will be best suited for Le Mans," said Darren Cox, Nissan's global motorsport director. Take a look below for a video and press release from Nissan documenting the ZEOD RC's build process.
