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.

Intel-Mobileye tech in 2M BMWs, VWs, Nissans will crowdsource maps for autonomy

Intel Chief Executive Brian Krzanich said on Monday 2 million vehicles from BMW, Nissan and Volkswagen would use its unit Mobileye's technology to crowdsource data for building maps that enable autonomous driving. The world's largest chipmaker bought Israeli firm Mobileye last year to compete with peers such as Qualcomm and Nvidia Corp and tap the fast-growing market of driverless cars, filled with a complex tangle of alliances. (VW, for example, is also working with Nvidia.) Krzanich was the keynote speaker at the Consumer Electronics Show. He said data from Mobileye's Road Experience Management software would gather data to build and update scalable high-definition maps. He also announced that Intel would be working with Ferrari on AI drones to cover Ferrari Challenge North America Series racing. The drones would provide video of the races, but ultimately they would provide drivers with data — video that would let them see their racing performance from overhead, but also telemetry information about, say, how they enter and exit a turn. Intel will also tie up with SAIC Motor Corp, which will use Mobileye technology to develop Level 3, 4 and 5 autonomous cars in China, the chipmaker said. Krzanich also said Intel had not received any information of customer data being compromised so far after the company confirmed last week that security issues reported by researchers in its widely used microprocessors could allow hackers to steal sensitive information from computers, phones and other devices. Security researchers had disclosed two security flaws exposing vulnerability of nearly every modern computing device containing chips from Intel, Advanced Micro Devices and ARM Holdings.
