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.

Nissan's Nismo celebrates 30th year with video retrospective

Nismo, the motorsports and high-performance arm of Nissan, has a lot of racing success to celebrate in its history and possibly even bigger accomplishments to look forward to. The company is commemorating its 30th anniversary with a video looking back at its most important milestones from each year of its past.
Nismo's job first and foremost at its genesis was to excel at motorsports. It wasn't too long after the division was founded in 1984 that the company made its first of many attempts to take an overall victory in the 24 Hours of Le Mans. It never quite succeeded in that goal, but still managed to do well in long-distance competition elsewhere. At the same time, Nismo was racking up wins in touring car races in Japan.
Eventually, the division's engineers started dipping their toes into tuning road cars, in addition to going racing. What began as something sporadic has become a growing part of the Nissan lineup with Nismo-branded models of the 370Z, Juke, Note in Europe and the GT-R.

Panoz and DeltaWing suing Nissan over BladeGlider concept

Similarity is bound to occur in an industry where most of the products follow the same basic formula. But once in a while a new design comes along that doesn't quite reinvent the wheel, but comes pretty damn close. The DeltaWing project was one such design - and Nissan, the car's designers allege, stole that design.
After the DeltaWing proposal was rejected by the IndyCar series, its creators took it to Le Mans and brought Nissan on board to supply the power. Nissan subsequently pulled out of the program and came out with the ZEOD RC hybrid racer (right), bearing a suspiciously similar design with an unusually narrow front track at the end of a long nose cone, and a wider track at the back. The Japanese automaker then displayed the BladeGlider concept (below, right) at the Tokyo Motor Show, envisioning a translation of the same formula into road-going form.
The similarity did not escape Don Panoz, who - after making sports and racing cars under his own name and founding the now-defunct American Le Mans Series - was a central figure in bringing the original DeltaWing to life. Now Panoz has filed a lawsuit against Nissan, soliciting the courts to issue a cease-and-desist order on both the ZEOD RC and BladeGlider projects, naming Nissan motorsport chief Darren Cox and Ben Bowlby (who defected to Nissan from the DeltaWing program) as part of the suit.
