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 Altima takes first V8 Supercars win

The V8 Supercars championship used to be strictly a contest between Holden and Ford. But just as BMW crashed the Audi and Mercedes party in DTM, so has Nissan (and for that matter, Mercedes) pushed past the door into Australia's popular touring car series. And like BMW, Nissan hasn't waited long before notching its first victory.
Nissan claimed the checkered flag this weekend in the first of three races at Winton, the ninth stop on the calendar. And what a spectacular win it was: not only did Nissan take the checkered flag, they finished one-two. James Moffat drove his Altima to the finish line just ahead of teammate Michael Caruso. It was Caruso who lead the first half of the race after qualifying just behind defending champion (and current points leader) Jamie Whincup, who suffered a gearbox malfunction and retired on only the ninth lap.
Of course that's just one race out of 27 so far and 37 scheduled this season, so that won't be elevating Nissan or any of its drivers to the lead the same way that BMW did upon its return last season to DTM, but it's a good start and a cause to celebrate for Nissan. Mark Winterbottom (Ford) and James Courtney (Holden) won the following two rounds at Winton as Jamie Whincup (Holden) leads Will Davison (Ford) in the standings.
