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.

Infiniti offers chance to design Sebastian Vettel's helmet for the USGP

The Circuit of the Americas will host its second United States Grand Prix in November, and based on what's happening with New Jersey it might be the only US torch left alight in the Formula One firmament. The story even before the inaugural event was about getting American fans involved, and Infiniti appears to be making the first splash this year with a competition to design Sebastian Vettel's helmet for the first two days of race weekend.
The only thing required of the graphic designer within you is to head to the competition site, download the helmet template and slather it in your unique technicolor vision. It will require some thought to make something interesting, though, since much of the helmet is already committed to team and sponsor logos; other than a few thin strips along the sides, your creativity will be confined to the oval atop the shell. Vettel will choose the winner and will wear the selected lid during the free practices and qualifying.
The grand prize winner will also get a VIP trip for two to the grand prix as a guest of Infiniti, which includes some face time with the triple world champion himself. The contest is on now, the deadline for entries is 11:59 pm GMT (6:59 EST), Sunday, September 29th and the winner is chosen the very next day. There's a press release below with more info if you want the complete skinny before putting stylus to digital paper.

Jay Leno recaps Pebble Beach

Each year at the Pebble Beach Concours d'Elegance the picturesque, ocean-side setting of the golf course becomes a parking lot for a vast array of multi-million dollar vehicles. However, if you missed the posh event this year, then Jay Leno has you covered yet again. For a nearly hour-long installment of Jay Leno's Garage, the comedian has dumped his denim in favor of a suit to take viewers on an insider tour of the lavish gathering. He interviewed some of the most talented designers in the auto industry, too. Leno starts off checking out a few beautiful classics by the shore, but things really get interesting for his stroll down the Concept Car Lawn for a scoop on the vehicles of tomorrow. Ed Welburn tells Leno all about the Buick Avenir, and Shiro Nakamura offers a tour of the Infiniti Q60. Plus, there are detailed looks at the Lincoln Continental, Hyundai Vision G Coupe, and Bentley EXP 10 Speed 6.
