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's Cummins tie-up bears first fruit with Frontier Diesel Runner concept

The 2014 Chicago Auto Show is proving to be a surprisingly big show for alternative fuels. The Chevrolet Silverado HD pickups are getting a compressed natural gas option and the refreshed BMW X3 is receiving a diesel engine, as is the German automaker's 7 Series. You can add one more oil burner to the mix, at least in concept form: Nissan has released its Frontier Diesel Runner Powered by Cummins with a 2.8-liter, four-cylinder turbodiesel engine and an eight-speed automatic transmission from ZF.
While Nissan calls the Cummins-powered Frontier a concept, it's really just a Frontier DesertRunner 4x2 with a diesel engine replacing the standard 4.0-liter V6, and it's meant to gauge consumer interest for a diesel option in the next-generation Frontier. Nissan has clearly noticed that Chevrolet will be offering a diesel in its new Colorado and wants to see how buyers will react to a mid-size alt-fuel pickup from a Japanese brand.
Exterior modifications to the concept are minor. To show off the engine, there is a transparent hood insert and the pickup has been painted in a two-tone finish of high-gloss red and matte silver edged in carbon fiber trim. The interior gets the same combo of red, silver and carbon fiber to match the outside.
