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.

Teen attempts car jump, hits windshield and lands on his feet

I've been compelled to do many things in or around a car, but jumping over one has never quite made the cut. That may be because I have all of the vertical lift of a manatee, but I digress. One enterprising young soul recently looked at a friend's Nissan Sentra and thought, "You know, I can totally leap right over that roof line."
By using what can only be described as Herculean feats of persuasion, he talked one young female friend into driving said Nissan straight for him at around 40 miles per hour while another stood by to film the lunacy. The plan went swimmingly right up until our would be compact-vaulter caught his foot on the hood and bounced into the windshield. Whoops.
But the story doesn't end with a trip to the emergency room. Our hero spun mid-air and actually managed to get his feet under him before coming back to Earth. Impressive. You can watch the hilarity for yourself below, but please, don't even think about trying this yourself.

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.
