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.

World's cheapest Nissan Leaf costs just $9,460

If you thought electric vehicles were expensive, head on over to Rotterdam in the Netherlands. There, you can buy a Nissan Leaf for the amazingly low price of just 7,450 euros ($9,460 US). Or, if a practical delivery van is more your style, check out the Nissan e-NV200 Visia Flex, which is absurdly priced at 4,950 euros ($6,400). Now, you might be thinking, those prices don't seem right, and this isn't a case of Nissan slashing the price like someone in I Know What You Did Last Summer. Instead, these deals are already and unsurprisingly being called the "world's best EV incentives." The great deals - available to businesses only – are due to generous national and local government incentives that are designed to take dirty vehicles off the road. Things like scrappage incentives (worth 2,500 euros, or $3,240) and free parking for EVs as well as home charger incentives stack up until they bring the price of a new EV down to the levels listed above. Jordi Vila, the managing director for Nissan Netherlands, told Automotive World that, "By scrapping older vehicles and incentivising buyers to replace them with zero-emission electric vehicles, Rotterdam is taking a huge step in improving air quality." As great as these deals are, it turns out that most car buyers are unaware of EV incentives. This is too bad, since there is a short but interesting history of tremendous deals on plug-in vehicles, like the $10,000 discount on the Mitsubishi i-MiEV (or the $69/month lease on that thing). For pure "dollars off" value, though, nothing beats the $30,000 in total incentives that maybe be available in some Japanese prefectures for hydrogen vehicles, which might expand all the way to free H2 cars.

Nissan Sentra, Buick LaCrosse to headline LA Auto Show

We're less than a month away from the start of the Los Angeles Auto Show, and automakers have been lining up their debuts for the upcoming left-coast expo. The latest announcement comes from the show's organizers who are eager to tout the global debuts slated for next month. Chief among them will be new versions of the Buick LaCrosse and Nissan Sentra. So far all we've seen of the 2017 LaCrosse is a glimpse at the front grille, but it's already promising to bring elements of the Avenir concept to the street. The original LaCrosse was launched in 2004 and was replaced in 2010 with the current model. The Sentra nameplate has been around much longer, but the current model was launched more recently in 2013. The new version spied recently while undergoing testing is promised to be a substantial update on that model, not a complete replacement, bringing it up to speed with the latest equipment and revised styling. This represents the first official confirmation we've received of when Nissan will be unveiling the new Sentra. Mitsubishi will also be on hand with its new Outlander Sport, as well as the redesigned Mirage. They'll be joined as well by new versions of a couple of high-end models that promise to resonate with the local crowds in tinseltown. Land Rover has chosen the LA show as a suitable venue to unveil the production Range Rover Evoque Convertible that will drop the top on one of the most stylish luxury crossovers on the market. And Porsche, as we know, is gearing up to hit the track with the new Cayman GT4 Clubsport - a customer racing version of the company's little two-seat, mid-engined sports car that's been lightly modified for motorsport competition. Of course these won't be the only new metal on display at the Californian auto expo. They'll be joined as well by the likes of the new Infiniti QX30, Hyundai Elantra, Kia Sportage, and Jaguar F-Pace - many of which we've already seen. Meanwhile companies like Fiat, Ford, Mazda, Mercedes, Subaru, Volvo, Volkswagen, and Elio Motors are keeping their plans under wraps for the time being. But with mere weeks to go, it won't be long before we see what they've got in store as well.
