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.

Daimler consulting with Ford about 3-cylinder engines

Soon enough, Ford will offer its 1.0-liter EcoBoost three-cylinder engine under the hood of the Fiesta here in the United States, building on the success of the small powerplant overseas. In fact, this success has caused other automakers to take notice, and according to Automotive News Europe, Daimler is now talking to Ford about this engine for use in its own products.
In other markets, Ford offers the 1.0-liter mill under the hood of the Focus (we had the chance to sample this package on our home turf), as well as the B-Max MPV. For this new collaboration, Daimler would use the turbo-three in the next-generation Smart ForTwo, as well as the Renault Twingo, which the German automaker will be collaborating on as part of its alliance with Renault-Nissan. Speaking to AN, a Mercedes-Benz engineer called the 1.0-liter mill an "interesting and impressive engine."
In exchange for details about the EcoBoost inline-three, Daimler will supply Ford with information regarding its Euro6 stratified lean-burn gasoline engine, which is found in the new E-Class sedan.

Nissan GT-R Nismo 'Ring time makes it track's 'fastest volume production car' [w/video]

Performance cars are fun to drive and all, but at the end of the day ,owners drop big bucks on what are often ridiculously unpractical vehicles for the bragging rights. And when it comes to ultimate bragging rights, few get more publicized than lap times for everyone's favorite stretch of German pavement, the Nürburgring. Enter the 2015 Nissan GT-R Nismo.
After rumors about a 7:08 lap time appeared yesterday, Nissan confirmed has confirmed the news today with video footage of the run, which took place on September 30. The official lap time is just seven minutes and 8.679 seconds, putting the GT-R Nismo about 11 seconds off the pace of the Porsche 918 Spyder - some six seconds quicker than the far costlier Lexus LFA. Some admitted - but hard-to-spot - missteps by Nissan driver Michael Krumm would indicate that the car actually left some time on the table.
With this time, Nissan claims that the 595-horsepower GT-R Nismo is the "fastest volume production car" around the track. The definition of "volume" could surely be contested here, though, considering the small numbers in which the GT-R is sold. While we don't have global GT-R sales figures, this year has only seen 1,063 units sold through October, and there were close to 1,300 sold in all of 2011 and about 1,200 in 2012. While this loosely defined claim will only add to the Nürburgring lap time squabbling, it is no less impressive. Check out the record run for yourself in the video below, which is accompanied by an official press release.
