Infiniti JX35 QX60 Hybrid confirmed for New York debut

The next Q-ified Infiniti will be making its debut at the New York Auto Show later this month, the QX60 - the crossover formerly known as JX35. And while there aren't many changes to the crossover in terms of design or function, the big news is that Infiniti will be revealing a production hybrid powertrain option for its seven-passenger luxury/utility vehicle.
The QX60 Hybrid uses the same powetrain found in Infiniti's M35h gasoline-electric sedan, which couples a 2.5-liter supercharged four-cylinder engine with a 15-kilowatt electric motor, running to the wheels via continuously variable transmission. Both front- and all-wheel-drive versions of the QX60 Hybrid will be available, and Infiniti says that the more efficient CUV should be good for around 26 miles per gallon combined - an improvement of five mpg over the current JX35 with its 3.5-liter naturally aspirated V6. And because the compact lithium-ion battery will be housed underneath the third row seat, we're told that the hybrid model will still have the same passenger and cargo capacity of the non-hybrid crossover.
This will be the first three-row hybrid CUV offered in the US market, and wrapping it up in a luxury package makes a lot of sense to us, since it could be a good way of cajoling customers into absorbing the extra cost of the more expensive powertrain. (Keyword in that sentence: CUV. After all, the Cadillac Escalade is still currently available as a two-mode hybrid for the 2013 model year.) Infiniti has not released official pricing figures, but says that the hybrid model will represent a roughly $3,000 premium over the standard QX60.

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 Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.
