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 sees its EV sales surging to 1 million annually by 2022

YOKOHAMA, Japan — Nissan announced plans to sell 1 million electric vehicles (EVs) annually by 2022, a six-fold jump from what it sold last year, and said it had no plans to stop testing its self-driving cars on public roads, calling them safe. Japan's No. 2 automaker and its rivals are planning to crank up development and production of electric cars in response to tightening emissions regulations around the world, even as demand for such vehicles remains limited due to their high cost and limited charging infrastructure. Launched as the world's first mass-market all-battery EV in 2010, Nissan's Leaf compact hatchback is the world's best-selling EV, though sales have been just around 300,000 units in its lifetime. The company now plans to focus its lower-emissions lineup on all-battery and gasoline-hybrid EVs rather than costlier technologies including plug-in hybrids. Nissan said on Friday it would develop eight new all-battery EVs over the next five years, including four models for China. Its luxury Infiniti brand would begin carrying new electric models from 2021, it added. Through 2022, vehicles powered by its "e-Power" gasoline-hybrid technology would likely comprise the majority of Nissan's electric line-up, it said. Such vehicles use gasoline to power the car's motor, requiring a much smaller battery than EVs and therefore are less expensive to produce. "The heart of our strategy in terms of electrification is battery EVs and e-Power technology," Nissan Chief Planning Officer Philippe Klein told reporters at a briefing. Concerns about EV battery costs and components have prompted many automakers to develop a variety of lower emissions technologies, but Klein said that Nissan would largely forego plug-in hybrids and hydrogen fuel cell technologies, given their low cost-performance at the moment. In 2017, Nissan sold 163,000 electric vehicles globally. Nissan and its automaking partners, Renault and Mitsubishi, together plan to launch 17 electric models as part of their strategy to achieve annual vehicle sales totaling 14 million units by 2022, compared with 10.6 million units in 2017. Self-driving tests to continue Automakers and technology companies are facing mounting pressure to prove that their automated driving functions under development are safe to use on public roads following a fatal accident involving a self-driving car operated by Uber Technologies [UBER.UL] in the United States earlier this week.

Demand for electric car rentals unplugged by range anxiety

It's the hurdle that electric vehicles must clear to be launched into the mainstream: range anxiety. But this time it isn't prospective customers who worry about running out of juice, Bloomberg reports, but renters who return to car rental agencies before their lease is up and trade their EVs in for more traditional gasoline-powered autos and gas-electric hybrids.
"People are very keen to try [electric vehicles], but they will switch out of the contract part way through ... they think they can't get to a charging station," says Lee Broughton, head of sustainability at Enterprise. Enterprise customers who rent EVs reportedly trade them in 1.6 days into the rental period on average, which compares unfavorably to the six- to seven-day rental periods of traditional, fuel-burning automobiles.
Christopher Agnew, an analyst at MKM Holdings LLC, says that longer range would help rental customers' range anxiety, especially since they are usually renting vehicles in unfamiliar places.
