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.

2016 Nissan Leaf with 107-mile range will start at $35,050* [UPDATE]

Here we go. Without making any huge leap into a second-gen model, Nissan has upgraded the 2016 Nissan Leaf from the 2015 model with a big range increase and a more durable battery. According to the new EPA numbers, the new Leaf will go 107 miles from a 30-kWh battery pack. That's going to get people's attention, since the current Leaf has an 84-mile range from a 24-kWh pack. You will still be able to get an 84-mile Leaf in the 2016 model year, since Nissan is keeping the S trim level with the lower, 24-kWh pack size. If you opt for the more expensive SV or SL trims, then you'll not only get the 27-percent greater range, but also a battery pack that is slightly heavier (by 46 pounds) and has more modules (eight vs. four) but the same number of cells. The two packs are the same size. In the end, the EPA rates the 30-kWh with 124 city, 101 highway and 112 combined MPGe fuel economy, while the S trim keeps the 126 city, 101 highway and 114 combined MPGe of the 2015 models. All the new 2016 Leafs keep the same 80-kW AC synchronous motor from earlier models. It still offers 107 horsepower and 187 pound-feet of torque. Prices for the new Leaf start at $35,050 for the Leaf SV (up from $32,950 for the 2015), $37,640 for the Leaf SL (up from $35,970) and $28,060 for the Leaf S (no change from 2015). All prices include $850 delivery charge but not the potential federal tax incentive of $7,500. The 2016's exterior is virtually identical to the 2015, aside from some new colors with names like Forged Bronze, Coulis Red and Deep Blue Pearl. Nissan is offering a few upgrades on the inside, though. There's a new graphic interface display on the 7-inch color screen (5-inch on the S trim) and a new "beam forming microphone" that should make the car's voice recognition better. The information that is displayed on the screen has also changed, with the charging screen info being updated every 12 miles. Given that some (but not all) of the rumors of this Leaf range bump turned out to be true, what do you all think of the talk of a 250-mile Leaf in about three years? UPDATE: The original headline quoted the price of the SL model instead of the less expensive SV, and has now been changed to accurately reflect the starting price of the SV. Both SL and SV come standard with the new 30 kWh battery, while the S model comes standard with the smaller 24 kWh pack. Thanks to those who pointed out this discrepancy!

Ghosn says having Apple in EV business would be good news

Nissan once promised to have commercially viable autonomous vehicles on the road by 2020 and even certified a Leaf to test the technology in Japan. The company has since backpedaled a bit from its original lofty claims, though. During CEO Carlos Ghosn's keynote presentation at the Mobile World Congress in Barcelona, Spain, the auto exec talked more about the automaker's strategy and directly confronted Apple's rumored entry into the market. "When Apple says they are going to come with an electric car in 2020, that's good news for us," he said in his speech, according to Adweek. Ghosn took the view that any company able to grow the acceptance of EVs would help every automaker in the segment. The Renault-Nissan Alliance has been at the forefront of developing the market and claimed nearly 60 percent of the global market share last year. He was also the latest auto industry heavyweight to voice his opinion on Apple entering the industry. However, in contrast to former General Motors boss Dan Akerson, the Nissan CEO was much more welcoming. Ghosn also used the speech as a chance to clarify Nissan's plans for autonomous vehicles and seemingly pushed the original goal back by about five years. "In 10 years, you'll have cars without the driver. It is here, and it's going to transform the products," he said, according to Adweek. Under Nissan's current timeline, traffic-jam assist and fully automated parking are due in 2016, followed by automatic lane changing in 2018 and the ability to drive through intersections without a driver's control comes in 2020.
