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.

2014 Rogue kicks off production as 10,000,000th Nissan built in Tennessee

News comes across our desks all the time of one manufacturer marking some milestone or another. But Nissan has just announced a double-whammy: Not only has Nissan's assembly plant in Smyrna, TN, just built its ten-millionth vehicle, but that ten-millionth vehicle just so happened to be the first Nissan Rogue to be built in the United States.
The milestone arrives after over three decades of production that has included such nameplates as the Sentra, Altima, Maxima, Leaf, Pathfinder, Infiniti QX60, Xterra, Frontier, and now the Rogue. The latter crossover has swelled into Nissan's second best-selling vehicle, with demand growing by nearly 50 percent from 2010 to 2012. Now redesigned for 2014 and built locally, Nissan is evidently banking on demand continuing to rise.

2015 Nissan Juke keeps its funky

The Nissan Juke is one of the most polarizing vehicles on the road today, but that doesn't mean it hasn't been a sales success, especially in Europe. Nissan is giving the the CUV its first styling refresh at the Geneva Motor Show. While the design changes will almost certainly be universal, the mechanical changes are still somewhat of a mystery for the US market. Nissan makes it clear in its press release below that it covers only the European model, and details about the North American model are coming later.
The exterior changes put a focus on making the Juke look a bit more angular and sporty. The lights on the fenders are now formed into a jagged point and somewhat echo the boomerang-shaped taillights. It also features Nissan's new, thicker V-shaped chrome grille. The door mirrors receive LED turn signals, and the lower portion of the rear receives a simulated mesh grille to look more aggressive. Other than some new color schemes, the interior is basically unchanged. However, the luggage area has been reshaped to increase storage capacity by 40 percent to 12.5 cubic feet (354 liters).
European buyers are getting a new 1.2-liter DIG-T turbocharged engine with 113 horsepower (115PS) and 140 pound-feet of torque (190Nm), and the 1.6 DIG-T also gets an increased compression ratio to produce 188 hp and is offered with either a six-speed manual or Nissan's Xtronic CVT. The all-wheel-drive system has also been upgraded with a torque vectoring system.
