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.

Recharge Wrap-up: Toyota battery breakthrough, PSA's millionth BlueHDi diesel

Scientists at Toyota have developed battery technology that allows for higher energy density. Using material from hydrogen storage, researchers at the Toyota Research Institute of North America (TRINA) in beautiful Ann Arbor, Michigan have created an electrolyte that works well with a magnesium metal anode. Besides improving energy density for smaller, more powerful batteries, magnesium is also more stable than lithium, making it a safer alternative. Rather than guarding their secret, Toyota is sharing details of this breakthrough in order to advance the technology in hopes of an earlier mass deployment of magnesium batteries. See the video above, and read more in the press release below. Farmdrop – a sort of online farmer's market in the UK – is looking for help naming its electric delivery "vanimals." The Nissan e-NV200 vans are painted and decorated to look like cows, pigs, and chickens. While three of the vans have already been named, fans can suggest their own clever ideas for the rest of the fleet on social media. Those whose names are selected will win a month's worth of shopping on Farmdrop. Cary McCarface, anyone? Read more at the company's website. PSA has built its millionth Euro 6 BlueHDi diesel engine. The automaker builds two diesel engines – a 1.6-liter and a 2.0-liter – at its plant in Tremery, France at a rate of 7,000 engines a day. BlueHDi technology uses three different emissions control mechanisms to filter pollutants out of diesel exhaust, including an oxygen catalyst, an additive filter to remove particulate matter, and a Selective Catalytic Reduction system to reduce NOx. BlueHDi is used in all new Peugeot, Citroen, and DS Euro 6 diesel vehicles. Read more at Green Car Congress. Charging Ahead Toyota Scientists Make Breakthrough on Safer, Smarter Batteries May 04, 2016 ANN ARBOR, Mich. (May 4, 2016) -- For anyone (i.e. everyone) who's ever panicked when their mobile device chirped, "low battery," the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A new breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones. What's the Big Deal with Magnesium? Magnesium metal has long been theorized as a much safer and more energy-dense alternative to current lithium battery technology.

Recharge Wrap-up: Tesla Model S in landslide, Plug'n Drive wants EVs

A woman and child survived a landslide in a Tesla Model S. The front of the car was severely damaged with the hood and front fascia badly crumpled. The rear hatch window glass caved in, but while the windshield was cracked, the safety glass held together. While in another vehicle, the occupants could have been crushed by the tree that landed on the car, the cabin structure of the Model S mostly withstood the pressure, saving the humans inside. It's not the typical situation most people think of when considering car safety, but it is a dramatic example of the protection the Model S offers.

Together the cars will drive a combined 400,000 kilometers (about 248,550 miles) emissions-free. The cars - a fleet of Renault Zoes, Nissan Leafs and Nissan e-NV200s - will be used as shuttles for the conference attendees. The Alliance will set up a network of 90 chargers for the event, powered by low-carbon electricity. The residual emissions will be offset through a UN carbon offsetting program.

The group says that adding electric power to more cars, "can make a significant contribution to GHG emission reductions in Ontario, while at the same time benefitting the Ontario economy." GHG are, of course, greenhouse gases. According to the group, there are currently more than 12,140 EVs in Canada. Read more in the press release below. Plug'n Drive advocates for electrification of transportation as a key plank of Ontario's climate change action strategy First ever Electric Vehicle Day at Queen's Park demonstrates the benefits of electric vehicles TORONTO, ON, Oct. 26, 2015 /CNW/ - Plug'n Drive is hosting the first ever Queen's Park Electric Vehicle Day today at 11:00 a.m., providing MPPs from all parties, Ministers, public servants, stakeholders and the public the opportunity to test drive electric cars at all price points and to learn about the environmental and economic benefits of switching from gas to electric.
