Nissan ZEOD RC on track and from behind the wheel

The Nissan ZEOD RC hybrid racecar has had mixed success in its competition life. It was invented to do a completely electric, high-speed lap at the 24 Hours of Le Mans, which it was able to do in practice. However, when the big event actually came, the car lasted less than an hour before it had to bow out with transmission issues. Nissan hasn't completely given up on its experiment, though. The experience (and possibly some of the tech) is going to help with the GT-R LM racer next year, and now the ZEOD is getting its chance to see how it handles the Top Gear test track.
Unfortunately, it's not The Stig piloting the ZEOD; instead, the magazine's motoring editor Ollie Marriage is the lucky man for the job. The car's sharp shape seems to be a good metaphor for how it handles because it just seems to dart around the track. Its tiny, turbocharged 1.5-liter engine with 400 horsepower and two electric motors put out a claimed 750 horsepower, and that seems like plenty for the relatively short Top Gear course.
As usual of Top Gear, the cinematography here is fantastic, and a second video shows off a single lap of the course from around the car. It's amazing to watch, especially with its big screen constantly showing the camera view out of the rear. Scroll down to see both.

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.

2013 Nissan Pathfinder: May 2013

Despite the snow-capped photos you see here, our long-term Pathfinder has been the subject of some proper pre-summer lovin' here in metro Detroit (we're working on a new gallery). Now that the warm weather has hit Michigan, many of our staffers have eagerly grabbed the keys to our big, brown Nissan for road trips all over the place. And the Pathfinder has indeed proven itself to be quite the worthy long-distance hauler, as editors John Neff and Seyth Miersma have already experienced.
This time around, a couple of our colleagues from AOL Autos put hundreds of miles on our trusty Nissan. And while everyone agrees that the Pathfinder is a solid vehicle for the task of road tripping, there are a couple of specific pros and cons that have been mentioned on several occasions.
