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 Nissan Pathfinder Hybrid priced from $35,110*

Nissan has announced pricing for the 2014 Pathfinder Hybrid, which was revealed earlier this year at the 2013 New York Auto Show. Offering two- or all-wheel drive, the hybridized crossover sports a 3.5-liter V6 and a 15-kilowatt electric motor, for a total of 250 system horsepower and 243 pound-feet of torque. Those numbers match up well with the 260 horsepower and 240 pound-feet of torque put out by the V6-powered Pathfinder. Naturally, fuel economy sees a hefty boost, to 25 miles per gallon in the city and 28 mpg on the highway, bumps of five and two mpg, respectively.
The Pathfinder Hybrid is available in three grades. Prices start at $35,100 for an SV and jump to $38,050 for the mid-level SL. A top-flight Platinum, meanwhile, moves the price up to $42,750. Adding all-wheel drive to the package bumps the price up to $1,600 across the range, and keep in mind that these prices don't include Nissan's $860 destination charge. Take a look below for the full press release from Nissan, including detailed pricing charts for both the Hybrid and V6 Pathfinder.

2015 Nissan GT-R updated with new lights, more refined ride

The Nismo version of Nissan's high-tech supercar may be getting most of the headlines today, but we shouldn't forget that the car on which it's based, the garden-variety GT-R, has been significantly updated for 2015, as well.
What Nissan engineers focused on for the new model year was making the GT-R a more well-rounded GT car. That means dialing some more compliance into the car's very firm suspension for a more comfortable ride, as well as lightening up the steering at low speeds to make urban maneuvering easier. The braking calibration has also been changed to be more linear and smooth when slowing from normal, everyday speeds. Does this mean the GT-R has gone soft? We'll reserve judgment until we drive it, but Nissan claims the new refinements giving the car "multi-dimensional performance."
The GT-R also gets new lighting technology for 2015, including multi-LED headlights that lend the car a new light signature at night, and the LED taillight rings are now complete circles instead of rings of dots. The headlights are also now controlled by an Adaptive Front Lighting System, which sounds similar to other systems that aim light where the car is being turned, but Nissan's system adjusts the angle of the lights depending on vehicle speed - at higher speeds the lights are angled to project their illumination further.
