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.

2017 Infiniti Q60 Coupe debuts with 400-hp V6

Infiniti killed it with the G35 Coupe in 2002, its second act being the G37 in 2008. The third act has officially begun, the 2017 Q60 Coupe launches today at the 2016 Detroit Auto Show. It hasn't strayed far from the concept shown a year ago, the major tweaks being government-approved headlights and side mirrors. Without discussing numbers, Infiniti says the new car is lower and wider than the current Q60, with a lower center of gravity, and it is more powerful and efficient. Much has gone on with the rolling stock, too: tighter wheel gaps, staggered tires on some models, wheels designed to absorb road vibration, and optional 20-inch alloys available for the first time. In the US, there are two engine choices with three levels of output. The twin-turbo 3.0-liter V6 comes with either 400 horsepower and 350 pound-feet of torque, or 300 hp and 295 lb-ft. In the US that will mean a boost of 70 hp and 80 lb-ft over the 3.7-liter V6 in the current car, and Infiniti estimates a combined fuel economy rating of 22 mpg. The 300-hp unit has a provisional rating of 23 mpg, the increased efficiency down to bodywork shaping and an active shutter behind the grille. A direct-injected, 2.0-liter, four-cylinder turbo is the second engine, getting 208 hp and 258 lb-ft and an estimated 24 mpg in the US. All engines will shift through an adaptive seven-speed automatic transmission. G'bye, manual gearbox. A Drive Mode Selector can dial through six settings, the Customize option throwing up three more individual choices to get the most from the updated internals. The V6 models can be optioned with Infiniti's second-generation Direct Adaptive Steering and brand-new Rack Electronic Power Steering that claims to provide more linear assistance. The four-cylinder comes with a speed-sensitive rack-and-pinion setup. Revisions to the base suspension include relocated shock absorbers among a new link layout, and modified shock tuning and bushings. Above that there's a brand new Digital Dynamic Suspension that will come standard on the Sport trim, now with adaptive dampers. Both units should have improved performance thanks to stiffer crossmembers. Finally, the cockpit gets dressed in one of three trims depending on the model, with aluminum or black wood at the entry-level end, carbon fiber at the other end, and silver glass fiber for buyers who choose the white or red leather.

2021 Infiniti QX80 gets full off-road prep, will take on the Rebelle Rally

Infiniti just revealed an off-road prepped QX80 that will take on the Rebelle Rally this week. Beginning today, the Rebelle Rally is an all-female rally where racers navigate off-road terrain from Lake Tahoe to the Imperial Sand Dunes by the U.S.-Mexico border. It’s 1,200 miles of rough terrain, so the luxurious QX80 needed a little help to get ready for it. The big bruiser of an SUV was handed off to Calmini Products Inc. in California for the prep work. It got a three-inch lift, heavy-duty control arms, off-road performance shocks, high clearance front and rear bumpers and thicker skid plates. The new Off-Road Monster 18-inch wheels are wrapped with chunky Nitto Terra Grappler all-terrain tires. We wouldnÂ’t normally say this about an Infiniti, but this QX80 looks badass. Calmini also added a PowerTank air-up tank and digital air-down kit to keep those tires at optimal pressure levels. Other extras include a rally computer, heavy-duty shackles and ropes, tow straps, two sets of Maxtrax platforms (to lift the vehicle for service if necessary), a fire extinguisher and two full-size spare tires secured in a custom-built cargo area cage. Both drivers are automotive journalists: Nicole Wakelin and Alice Chase. TheyÂ’re allowed compasses, roadbooks and maps, but no other navigational tools are available. The rally is scheduled to conclude on October 17. InfinitiÂ’s QX80 is a fine choice for this event, especially when you consider its underpinnings. The big SUV still uses a body-on-frame construction shared with the Nissan Armada. Nissan enthusiasts will also know that the Armada is based on the Nissan Patrol, which is a capable off-roading truck of an SUV sold in other parts of the world.
