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 Rogue kicks off production as 10,000,000th Nissan built in Tennessee

News comes across our desks all the time of one manufacturer marking some milestone or another. But Nissan has just announced a double-whammy: Not only has Nissan's assembly plant in Smyrna, TN, just built its ten-millionth vehicle, but that ten-millionth vehicle just so happened to be the first Nissan Rogue to be built in the United States.
The milestone arrives after over three decades of production that has included such nameplates as the Sentra, Altima, Maxima, Leaf, Pathfinder, Infiniti QX60, Xterra, Frontier, and now the Rogue. The latter crossover has swelled into Nissan's second best-selling vehicle, with demand growing by nearly 50 percent from 2010 to 2012. Now redesigned for 2014 and built locally, Nissan is evidently banking on demand continuing to rise.

Renault-Nissan promises 10 autonomous models through 2020

Renault-Nissan boss Carlos Ghosn promised back in 2013 to have autonomous technology on the road by 2020, and now the automaker has pledged to have more than 10 models ready in that time with varying levels of autonomous capabilities. The company claims it will offer these systems to customers around the world at affordable prices in major markets like the US, Europe, Japan, and China. Renault-Nissan will introduce driverless tech in multiple phases over the next four years. The first step will come later this year with the introduction of a single-lane autonomous system that will be able to go down the highway and manage stop-and-go traffic automatically. The next innovation in 2018 will offer multi-lane capability, and the ability to automatically pass other vehicles on the road. Another big jump will come in 2020 with the ability for models to navigate intersections and urban areas without a driver's control. Renault and Nissan engineers will develop all of this together, and the results will be available in both of the company's brands. Ghosn explained this roadmap towards an autonomous future last year but cautioned that Renault-Nissan didn't plan to take complete control away from owners. Instead, the company sees these systems as a way to make people even safer behind the wheel by reducing the chance for driver error. The automaker's deliberate introduction strategy is prudent because it can potentially adapt to proposed regulations that could mandate rules on how piloted vehicles operate. RENAULT-NISSAN TO LAUNCH MORE THAN 10 VEHICLES WITH AUTONOMOUS DRIVE TECHNOLOGY OVER THE NEXT FOUR YEARS World's fourth largest car group confirms autonomous drive and connectivity timeline through 2020 Fatal and serious injuries have been significantly reduced; new technologies will help make cars even safer Car group hires new executive to oversee connectivity and connected car services globally SUNNYVALE, Calif. – The Renault-Nissan Alliance will launch more than 10 vehicles with autonomous drive technology in the next four years. The global car group confirmed today that it will launch a range of vehicles with autonomous capabilities in the United States, Europe, Japan and China through 2020. The technology will be installed on mainstream, mass-market cars at affordable prices. In addition, Renault-Nissan will launch a suite of new connectivity applications that will make it easier for people to stay connected to work, entertainment and social networks.
