2015 Nissan Pulsar and Pulsar Nismo Concept show Jekyll and Hyde for the hatch

Nissan is showing two very different sides of its new Pulsar five-door hatchback (on the right) at the 2014 Paris Motor Show. On one hand you get to see the standard version hoping to take the fight to popular European models like the Volkswagen Golf and Ford Focus, but also on the stage is our first glimpse at the Pulsar Nismo Concept (above) that demonstrates the vehicle's more devilish side.
The standard Pulsar is hoping to make a dent in the Euro C-segment ranks. It rides on the same platform as the Nissan Qashqai crossover and is actually about 2.4-inches longer than the Golf. Power comes from a trio of choices. There are 1.2-liter and 1.6-liter turbocharged gasoline engines with 113 horsepower and 187 hp, respectively, and a 1.5-liter diesel with 108 hp. CVTs are offered with them all. The Pulsar is also available with a variety of safety tech, including forward emergency braking, lane departure warning and blind spot monitoring.
However, the real excitement comes from the new Nismo Concept. Nissan is clear that it's "only a design study at this stage," but the sporty hatch imagines a flagship for the Pulsar range. It gets the full suite of Nismo goodies with a suspension dropped to the floor and sharper steering. The exterior also benefits from big air intakes in the front bumper, a rear diffuser with central exhausts, flared fenders and carbon fiber trim pieces. The whole thing is finished in satin gray with the division's traditional red trim. The interior has the same motif with race seats and a three-spoke steering wheel.

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 recalling more than 1M vehicles for airbags that may fail to deploy

Nissan and the National Highway Traffic Safety Administration have issued a recall for 989,701 vehicles in the US due to an issue with their passenger-side airbag systems. Affected Nissan models include the Altima, Leaf, Pathfinder and Sentra from the 2013 and 2014 model years, and 2013 NV200 taxis. Affected Infiniti models include the 2013 JX35 and 2014 Q50 and QX60 utility vehicles.
Reuters is reporting that a total of 1,053,479 vehicles are included in the recall globally, with about 60,000 of the affected vehicles having been sold in Canada.
The fault apparently lies in something called the occupant classification system, which may, in the recalled vehicles, incorrectly classify the passenger seat as empty when it is in fact occupied by an adult. When the system fails to recognize the passenger, the passenger-side airbag may deactivate, and could therefore fail to deploy in the event of a crash.
