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.

2013 Nissan Pathfinder: Wrap-Up [w/video]

Despite our tendency as enthusiasts to clamor for things like wagons and hot hatchbacks, it's hard to argue with the buying public's increasing demand for functional crossovers. In fact, the great SUV craze of the late-1990s has all but faded in favor of the easier-driving, better-packaged, more-efficient crossover. That's even true at the larger end of the market - just look at what happened when Ford redesigned its body-on-frame Explorer into a stylish and well-equipped CUV. And now look at the similar success Nissan has had in repurposing its rugged Pathfinder sport-ute as an appealing crossover.
But happily, we report the following line: out of every long-term vehicle Autoblog has ever tested, not a single one has been as in-demand as the 2013 Pathfinder Platinum you see here. After 13 months of solid use, we added 24,372 miles to the Pfinder's odometer - and that's without the vehicle ever leaving the hands of our Detroit-based team (sorry, West Coasters).
There's good reason for that high-demand usage, too. After spending a little over a year with our Mocha Stone tester (a color that earned this Nissan the nickname "Sweet Brown") we came to appreciate its vast versatility, comfort, all-weather prowess, and the way it absolutely ate up the miles on long trips. We drove it all over the United States, in all four seasons, filling it with our families, friends, and occasionally using its capacious cabin for sleeping on the road. Through good and bad, the Pathfinder was a trusty friend. But like any good friendship, that wasn't without a couple of fights.

Dacia Duster to spawn inexpensive Nissan Terrano, will we get it?

When going to overseas auto shows, one can't help but spend an inordinate amount of time eyeballing forbidden automotive fruit. It's often of the seriously rare, criminally powerful and six- or seven-digit variety. But more often than one might think, the genuinely affordable overseas hero makes us swoon, too. So it is with the Dacia/Renault Duster, the cheap-as-chips, hard-wearing utility vehicle. We've often thought that its basic, rugged charms would play well in the US if saddled with a low enough price tag, but we've never seen much of a window for that to actually come true.
But now, Autocar India is reporting that Nissan will flex its alliance with Renault to spin off a Duster of its own, one that exhumes the Terrano nameplate, a moniker once used for overseas versions of the first- and second-generation Pathfinder. The new model will feature unique sheetmetal to give it a familial look, but the interior will be the same, and we expect the same goes for the powertrain, meaning there will be a range of gasoline and diesel four-cylinder engines with both manual and automatic gearboxes and front- or all-wheel drive.
So, does that mean we'll get a Nissan version of the Duster-based Terrano to call our own? Sadly, almost certainly not. Company spokesman Dan Bedore tells Autoblog flatly, "There are no plans to bring this model to the US." Bummer. Even if it isn't ultimately as capable as the larger, long-in-the-tooth Xterra (it's more on par with the now departed Canadian-market X-Trail), we think the Duster's archetypal SUV looks and low cost barrier would win it plenty of fans in our market. Our guess is that redesigning the model to meet US regulations (crash, emissions, lighting, etc.) would be prohibitively expensive, and the Dacia/Renault model is built in some pretty distant facilities - Brazil, India, Romania and Russia among them - making the business case harder still.
