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.

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.

Infiniti G37 to live through MY 2015, sell alongside Q50

Infiniti has officially confirmed news we broke last month about its G37 sedan - that it will live on in showrooms alongside its erstwhile replacement, the 2014 Infiniti Q50, a model that goes on sale this week. And it's sticking around for quite a while - it will be sold through the 2015 model year.
In order for the G37 and Q50 to not rub shoulders, Infiniti is rolling out an amended G lineup, complete with lowered pricing. The G37 will stick around in Journey and all-wheel drive trims, both powered by the same 3.7-liter VQ-Series V6 engine, and only two option groups will be available, Premium and Navigation. The 2014 G37 Journey will start at $32,550, while the G37 Sedan AWD will run $34,150 (both are subject to a $905 destination fee).
The 2013 G37 had been priced from $38,255 delivered as of earlier this week, so the price drop is significant, likely bringing the base MSRP more in line with where transaction prices had been on the aging model. The new pricing, which takes effect August 6, should also allow the G37 gain consideration amongst shoppers of smaller-engined rivals like the BMW 320i while the Q50 waits on a turbocharged four-cylinder and diesel engine from Daimler. For comparison's sake, the larger, more tech-rich Q50 will start at $37,605 delivered.
