A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

2022 Infiniti QX80 gets an interior update with new, big touchscreen

The 2022 Infiniti QX80 is getting a light interior update in the form of a new touchscreen infotainment system and center stack. If you’ve seen the 2021 Nissan ArmadaÂ’s refreshed interior, then youÂ’ve seen the new QX80Â’s, because they share the same center stack and touchscreen now. This new infotainment system runs on a 12.3-inch high-res screen that sits perched at the top. ItÂ’s capable of wireless Apple CarPlay, but only wired Android Auto. Infiniti says navigation comes standard, too. We liked the new touchscreen in the Armada far more than its outgoing unit, which was ancient technology by the time it was replaced. This new screen is vibrant, features much quicker responses to inputs and is all around a massive step up in tech. YouÂ’ll see the new QX80 also has all the updated controls below the touchscreen, too. We get new dials and buttons (far fewer than before) for the radio and climate controls. Plus, the new layout necessitated a new air vent design. Say goodbye to the dual-screen layout, too, as thereÂ’s no second touchscreen in the lower part of the stack — thatÂ’s a very good thing. Taking up some of that space is a new storage cubby that can be hidden via a piece of wood trim. Flip it open, and youÂ’ll reveal a wireless phone charger and access to a 12-volt outlet.  Besides this interior change, the rest of the 2022 QX80 is carryover. It looks the same from the exterior, and itÂ’s still rocking the 5.6-liter V8 that makes 400 horsepower and 413 pound-feet of torque. Neither pricing nor availability for the updated QX80 were made available today, but donÂ’t expect it to be too much more than the $70,545 base price it enjoys now.

2014 Infiniti QX60 Hybrid

Infiniti launched its seven-passenger JX crossover for the 2013 model year with the automaker's familiar 3.5-liter V6 as standard equipment. For 2014, the model was renamed the QX60, and a new variant packing a gasoline-electric hybrid powertrain joined the lineup. (For those interested in the family lineage, the new arrival is a mechanical twin to the Nissan Pathfinder Hybrid, which we took for a Quick Spin last year).
Hidden beneath the hood of the QX60 Hybrid is a supercharged, 2.5-liter inline four-cylinder engine, rated at 230 horsepower and 243 pound-feet of torque. The combustion engine is supplemented by a 15-kilowatt electric motor, fed by a small lithium-ion battery back (hidden under the rear cargo floor), which adds 20 hp and 29 lb-ft of torque to the mix. Added up, Infiniti rates the total system power at 250 hp and 243 lb-ft - numbers that fall just short of its combustion sibling (the 3.5-liter V6 in the QX60 is rated at 265 horsepower and 248 pound-feet of torque). The only gearbox is a continuously variable transmission that drives either the front or all four wheels, depending on what the buyer specs.
The 2014 QX60 Hybrid AWD starts at $46,500 (the green model commands a $3,000 premium over the gas-only model). A long list of factory options such as Roof Rails ($495), Theater package ($1,700), Deluxe Technology package ($6,050), illuminated kick plates ($440) and a Hybrid Premium package ($4,600) bumped our as-tested price to a healthy $60,780, including $995 for destination.
