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.

Bathurst 12-hour gallery is GT3 heaven [w/video]

The 2015 Liqui-Moly Bathurst 12-Hour race was run this weekend at the Mt. Panorama Circuit in Bathurst, Australia. Race photographer Joel Strickland sent us a huge batch of photos, all of which make us salivate for the switch to GT3 rules in the United SportsCar Championship; the top seven finishers at Bathurst were of seven different makes: Nissan GT-R NISMO GT3, Audi R8-LMS Ultra, Aston Martin Vantage GT3, Bentley Continental GT3, Mercedes SLS AMG GT3, Ferrari F458 Italia and Lamborghini Gallardo. It was a sweet victory for the No. 35 car driven by the NISMO Athlete Global Team after it crashed in Saturday qualifying, and then was only in third place on the penultimate lap. The three-man driving team included two GT Academy winners, one of whom, Florian Strauss, has only been a professional race car driver for 18 months. It's the first time the GT-R has won at Panorama since the original R32 "Godzilla" took back-to-back wins in 1991 and 1992. Second place went to the No. 15 Phoenix Racing Audi R8-LMS Ultra, 2.4 seconds behind the winners, third to the Craft Bamboo Racing Aston Martin Vantage not even half a second behind the Audi. The Bentley Motorsport team, in its first Bathurst 12-Hour with two cars, had its No. 10 Continental GT3 in the lead until the penultimate lap and in second place until the final corner, but crossed the line in fourth after some rubbin'-is-racin' action from chasers. And if pictures aren't enough, as of writing you can still watch the live stream of the entire race at the Bathurst 12-Hour site. Or, if you don't have the time, at least be sure to check out the last five minutes, below. Enjoy.

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
