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 Safari police truck a sort of A-Team van from Japan

Television today might be at one the best points in the medium's history with shows like Mad Men, Louie, True Detective and streaming offerings like House of Cards. However, none of those come close to the number of car chases and explosions of '70s and '80s offerings like Charlie's Angels, The A-Team or The Dukes of Hazard. Apparently, this prevalence of action at the time wasn't just an American phenomenon. In Japan, a show called Seibu Keisatsu fulfilled the nation's need for shootouts and stunts.
Nissan was a major sponsor of the show, and therefore the brand's vehicles were used extensively, including a highly modified Nissan Safari SUV (also known as the Nissan Patrol), pictured above. In the show's lore, it was equipped with radar, a camera and a fire extinguisher capable of turning over a car. The series ran 236 episodes from 1979 to 1984, and with the trailer below as indication, that allowed time for plenty of car jumps and explosions.
The entire Seibu Keisatsu series is now coming out in Japan on DVD and Blu-Ray packed in a fake gun case. The trailer below shows off some of the action of the series. It all starts out normal enough, but about a minute into the video there are all sorts of Nissans jumping and crashing. Plus, there is a guy on fire in a shootout. This show looks like some seriously cheesy fun. Scroll down to get a taste of it.

Did Nissan send a ringer GT-R to run the 'Ring? [w/video]

It turns out that after toting a 7:08 time around the fearsome Nürburgring Nordschleife for the new Nismo-tuned GT-R, Nissan might not have been entirely honest about the car it was using. From what we've been hearing from a few different publications, the GT-R featured in the video isn't what we're going to see on the production model.
PistonHeads reported on the so-called "Time Attack" GT-R while it was in Japan for the Tokyo Motor Show, going so far as to detail the differences between it and the standard GT-R Nismo. And friends, this isn't just a matter of swapping tires. The mods made to the Time Attack car are far more comprehensive.
For a start, the TA produces more downforce thanks to larger aerodynamic pieces. It's some 110 pounds lighter than the standard car, thanks to new bucket seats. The ECU and dampers have been swapped for new units, and the brake pads are different as well. If you've read this far, you might be feeling slightly angry or betrayed that Nissan is toting numbers for a modified car. Don't be.
