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 Q60 Coupe spied in production guise

Here is the best news we've had all day: the production Infiniti Q60 Coupe will bear an uncanny resemblance to the concept car that previewed it earlier this year in Detroit. We know this thanks to our very first round of spy photos of the heavily camouflaged production car. Although there are only three images to draw from, we've got a clear picture of the concept-inspired lines of this new two-door. In particular, the front and rear fascias look to draw a lot of inspiration from the concept. In front, the headlights look to be similar in shape, while the double-arch grille looks largely unchanged from what the company previewed. Perhaps the biggest change up front is around the fog lights, which look to sit in far more conventional housings. Also gone is the Q60 Concept's Formula One-inspired chin, possibly in part due to the company's (and parent Renault's) perilous position as a title sponsor for the Red Bull Racing team. The taillights reinforce the concept car inspiration, retaining a similarly svelte shape and tying in with a small trunk lid. Also like the Q60 Concept, our spies report that a twin-turbocharged, 3.0-liter V6 will be on offer, likely as the range-topping engine. We'd expect the volume motor to be the Mercedes-Benz 2.0-liter, turbocharged four-cylinder found in the likes of the new Q30, as well as the CLA-, GLA-, and A-Class. It's also certainly possible that Infiniti's long-serving 3.7-liter V6 will be available in some form. Whatever engines arrive, we can expect six-speed manual and seven-speed automatic transmissions to be the sole options. Have a look at the photos up at the top of the page. And for comparison's sake, we've included the official Q60 Concept gallery down below just under the video showing a 360-degree view. Take a peek at both and let us know what you think of Infiniti's work.

2014 Infiniti Q50 configurator comes alive

The G37-replacing 2014 Infiniti Q50 sport sedan launches in the not-too-distant future, and for those curious about how pricing and packages will shake out, the car's official online configurator has been launched. Here, you can build the Q50 or Q50 Hybrid of your dreams, with the cost of entry starting at $36,450 (plus $905 for destination).
Selecting the hybrid model adds $7,250 to that bottom line - mostly because the gasoline-electric version is only available in the Premium trim and higher, while the gas-only Q50 comes in a base guise. Adding all-wheel drive, which Infiniti has made available with either engine and on all trims, will set you back $1,800.
There are a number of packages available across the trims, including a $1,400 navigation pack that includes a spare tire kit, a deluxe touring pack that costs $4,700 (and includes the navigation goodies), and the upper-crust $7,900 technology package which gets you, well, everything. Put that all together on a Venetian Ruby Q50 RWD Sport like we did, and you're looking at $51,755 when destination has been added.
