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.

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.

Infiniti Q50S getting G37's hydraulic steering for 2016

Sometimes, new technology doesn't make things better. Take the march of power steering technology as an example. Electrically assisted systems are in vogue at the moment for their ability to increase fuel efficiency, but tuning them to offer good feedback remains something of a dark art. Some automakers get it, but most don't. The previous hydraulically assisted setups just seem to be inherently more communicative when driven with enthusiasm. And it looks like Infiniti might be learning this lesson the hard way.
In talking with Keith St. Clair, the luxury brand's head of product planning, Car and Driver has learned that the Q50S is probably going to ditch its standard electrically assisted steering in favor of a hydraulic system derived from the old G37, a model soon to be renamed the Q40. The system should make the sedan more engaging behind the wheel, but it still won't help those who tick the option box for Infiniti's controversial Direct Adaptive Steering drive-by-wire system.
According to St. Clair, Infiniti's engineers have heard the complaints of critics and previous G37 owners about the Q50S model's electric steering system, and wanted to see what they could do. They didn't have to go far to figure it out - all it required was taking the steering rack off of a G37 and putting it onto the Q50S. After a little tweaking, "the car is a blast to drive," St. Clair reports. Now, the company is said to be fast-tracking the switch, and it could be ready for the 2016 model year.
