New Nissan Pulsar marks brand's return to the European C-segment [w/videos]

Following a small teaser, Nissan has unveiled its newest entry into the hotly contested European C-segment. Making new use of the Pulsar nameplate, it will attempt to take the fight to market stalwarts, like the Ford Focus, Volkswagen Golf and Vauxhall Astra.
The new five-door will be built on Nissan's modular CMF2 architecture, which also underpins the Euro-spec Qashqai and X-Trail (known in the US as the Rogue). It's a larger vehicle than one of its main challengers, the Golf, riding on a 106.3-inch wheelbase, which is 2.4 inches longer than the VW. It's also longer overall, at 172.6 inches.
The new Pulsar is a moderately powered little five-door, boasting an engine lineup familiar to anyone that knows the Qashqai. A 1.2-liter, turbocharged gas engine offers up 113 horsepower, while those that need a bit more oomph can wait for the late-availability, 187-hp, 1.6-liter turbo that American drivers will know from the Juke crossover. Diesel fans will be able to opt for a 1.5-liter mill that delivers 192 pound-feet of torque and 108 hp. No surprise here, but continuously variable transmissions are the order of the day.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

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.
