Nissan Versa Sedan

Compact sedans are all the rage, with a host of new entries from both domestic and import manufacturers reaching showrooms recently. Nissan will cash in on that popularity with the 2012 Versa sedan, debuting today at the New York auto show with refreshed styling and tweaks to improve fuel economy.

The 2012 Versa rides on an evolution of the last car's platform called V, for Versatile. The sedan's wheelbase and width are unchanged from the current model, but it loses about an inch of length and height. Despite this, Nissan says that packaging improvements for the engine and transaxle mean there is more trunk space. The new car also should be marginally lighter than before.

Styling-wise, the new Versa takes cues from the larger Altima and Maxima sedans, starting with a new grille design and oval-shaped headlights, and continued with a smoother rear and reshaped taillights that sweep from the rear bumper to the Versa's rear haunches. The hood and sides are broken up by an assortment of creased character lines akin to those seen on the Hyundai Elantra. Whereas the old Versa had a more conventional flat roof and steep rear window, the new car's roofline gently slopes toward the trunk, following the coupe-like trend. The exterior changes reportedly help achieve a low 0.31 drag coefficient.

Nissan LEAF

It would be easy to paint Nissan as late to the burgeoning U.S. green party, as the company essentially only counts the Altima Hybrid to sell among its alt-fuel offerings – and that sedan utilizes technology borrowed from Toyota, and it's only sold in a few states in small volumes. While that may be the case, Nissan says their near-term prospects are really quite different. While the company has admittedly been cautious in marketing alt-fuel vehicles in North America, they have been hard at work developing electric vehicles – as well as the advanced lithium-ion batteries to support them – since 1992. What's more, officials say they are now singularly well-placed to leapfrog "transitional" powertrain solutions like gas-electric hybrids in favor of genuine zero-emissions vehicles, and they are promising that their first pure-electric car will reach U.S. shores late next year.

That car, the Nissan Leaf shown here, is the reason we find ourselves in the company's brand-new Yokohama headquarters today. Designed as a four-to-five seat, front-drive C-segment hatchback, Nissan says the Leaf is not just for use as a specialty urban runabout, but rather, it was designed as an everyday vehicle – a "real car" whose 160-kilometer+ (100 mile) range meets the needs of 70% of the world's motorists. In the case of U.S. consumers, Nissan says that fully 80% of drivers travel less than 100km per day (62 miles), making the Leaf a solid fit for America's motoring majority, even taking into account power-sapping external factors like hilly terrain, accessory draw, and extreme temperatures.

We were afforded an advance look at the Leaf ahead of the car's unveiling today, and while it was a hands-off affair, we did have the chance to formulate some in-the-metal first impressions and take a deep dive into the car's technology. Click through to the jump to learn all about it.
