Nissan GT-R LM hobbled by 'very minor' issue during Sebring test

We're always going to have a soft spot for the Rolex 24 at Daytona. It marks the start of the endurance racing season, after all. But it's the endurance racing circus' three-hour drive south for the annual to-do at Sebring International Raceway that really sets our hearts aflutter. That's because Sebring is generally used by the biggest teams as a tune-up for June's 24 Hours of Le Mans. The Floridian race might only be half as long, but the sheer brutality of the racing surface makes it a great test of a racer's durability, hence why it's a popular stop on the way to France. As it turns out, it was the track's roughness that was the reason Nissan decided to piggyback on one of Audi's tests at the south Florida circuit, Autosport reports. But an issue "to do with the engine mounting" on the front-engined GT-R LM racer sidelined the team. "It was actually a very minor thing, but we just don't have a spare here," Technical Director Ben Bowlby told Autosport. "We've spent a lot of time at Austin, which is very smooth, so we wanted to come to a particularly harsh environment like Sebring." While it seems rather silly to test somewhere in an attempt to "accelerate the durability cycle" without packing a full complement of spares, the rough surface of Sebring has a tendency to wreak havoc with even the most reliable of parts. Nissan did manage to run a total of 68 laps over the course of two days, with drivers Marc Gene and Olivier Pla at the wheel. At present, Nissan won't be running the GT-R LM in the actual 12 Hours of Sebring – it's first race outing will instead be at the 6 Hours of Silverstone, running next month. Related Video:

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands

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.
