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 Nissan Leaf EVs recalled for missing welds

The Nissan Leaf has been recalled before, for problems with the passenger-side airbags. Early models of the car has also had start-up issues, but those did not lead to a recall. Today, we're learning about another problem with the world's most popular electric vehicle. In April, the National Highway Traffic Safety Administration issued a recall of a small number of 2014 model year Leaf EVs - just 211 units that were made between February 28 and March 12 of this year – and reminded the world about it this morning with a Tweet. The problem, NHTSA says, is that, "the front structural member assembly may be missing welds," and that means that the car's structural integrity could be compromised in a crash. You don't say. Starting in the middle of June, Nissan will look at the vehicles that could be missing welds and offer replacements for free. If you have a potentially affected vehicle, Nissan should be contacting you soon, or you can call the automaker at the number listed below. Report Receipt Date: APR 16, 2014 NHTSA Campaign Number: 14V192000 Component(s): Potential Number of Units Affected: 211 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2014 LEAF vehicles manufactured February 28, 2014, through March 12, 2014. The front structural member assembly may be missing welds, which could reduce the structural integrity of the vehicle if the vehicle is involved in a crash. As such, these vehicles fail to meet the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection," and 305, "Electric-Powered Vehicles: Electrolyte Spillage and Electrical Shock Protection." CONSEQUENCE: Missing welds may effect the vehicle's integrity in the event of a crash, increasing the risk of injury to the vehicle's occupants. REMEDY: Nissan will notify owners, and dealers will inspect to see if any of the welds are missing. Any vehicle missing welds will be replaced, free of charge. The recall is expected to begin by mid-June 2014. Owners may contact Nissan at 1-800-647-7261. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Nissan starts building e-NV200 in Spain [w/video]

It doesn't look all that much like a Nissan Leaf, but the new e-NV200 that started production in Barcelona, Spain today shares its powertrain and lithium-ion battery with the world's most popular electric vehicle. The production version of the electric cargo van was unveiled late last year and today's manufacturing start is right on time with the company's previously announced timeline. The first exports will take place in June. The e-NV200 is Nissan's second all-electric vehicle, and the company says that powertrain line-up is "expanding." The vehicle itself will be available in a number of configurations in Europe: a light commercial van, a passenger vehicle and and electric taxi. Nissan has said in the past it is working on installing a fast-charging network of CHAdeMO stations in Barcelona, where the e-NV200 will be used as a cab. The e-NV200 will also be used as an electric taxi in Amsterdam. The zero-tailpipe-emission van is also being tested in Washington, DC with FedEx, but there is no confirmation that it will ever be commercially available in the US. There are a few more details, and a video, on the e-NV200 production start below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
