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 expands US EV test market for e-NV200 to Portland

Of course, it's going to be Portland. Oregon's largest city, known for its green-friendly vibe and policies, will be where Nissan will next test of its all-electric e-NV200 cargo van. And we hope those vans have cup holders for the inevitable java. The Japanese automaker is working with local utility company Portland General Electric (PGE) on a six-week trial program. Nissan and PGE will record data to better measure how the concept of battery-powered driving works within the local services network. The location makes sense, as Portland is one of the five best-selling US cities when it comes to sales of the Nissan Leaf, which shares its powertrain with the e-NV200. Nissan kicked off its "No Charge to Charge" free-charging program for new Leaf owners in April. Nissan, which had already been testing the e-NV200 with FedEx in Germany, Japan and Singapore as of late last year, said at the Washington Auto Show in January that it would start testing the electric van in the Washington, DC, area. Nissan said at the time that it helped install about 570 fast-charging CHAdeMO chargers throughout the US since last year, including 200 in December alone. Check out Nissan's press release about the Portland project below. LEADING EV MARKET PORTLAND BECOMES TEST BED FOR NISSAN E-NV200 ELECTRIC COMMERCIAL VEHICLE PORTLAND, Ore. – Portland, already a top breeding ground for electric vehicle (EV) sales, is now the proving ground for Nissan's prototype electric commercial vehicle – the Nissan e-NV200. Nissan is working in collaboration with Portland General Electric (PGE) on a six-week trial to help determine the viability of an electric commercial vehicle in the U.S market. PGE has assigned the e-NV200 into its fleet of vehicles with an underground crew, replacing a larger, diesel-powered van. "Oregon has been a top five market for Nissan LEAF sales in the U.S. due to proactive policies at the state level to encourage EV adoption, as well as robust charging infrastructure championed by the state and others like PGE," said Toby Perry, Nissan's director of EV Marketing in the U.S. "If we determine that e-NV200 fits into the U.S. commercial vehicle market, we expect that Portland would be a leading driver for sales as well." This year, Nissan is deploying two e-NV200 prototypes with companies such as PGE and FedEx in top U.S EV markets including California, Georgia, Oregon and Washington, D.C.

Club to restore amazeballs Datsun Safari Rally Z

Thanks to the Nissan Restoration Club, a legendary rally car is coming back to life. At the recent Nissan 360 media event, the Japanese automaker announced that its restoration club is bringing the Safari Rally Z back to original running condition. A variant of the Fairlady Z (or Datsun 240Z in the US), the Safari Rally Z has a fastback coupe body and a 215-horsepower inline-six engine. It won East African Safari Rally championships in both 1971 and 1973. The restoration is scheduled for completion this December.
Formed in 2006, Nissan's Restoration Club is comprised of 60 volunteer members who are passionate about Nissan's historic racecars. The club's past restoration projects include the 1964 Skyline racecar and 1947 Tama electric vehicle. Read the press release below for all the details on the latest restoration, and check out the gallery for photos of the Safari Rally Z as well as the 1972 Fairlady 240Z.
