These sketches are our first teaser glimpse at the production version of Kia’s new generation Optima sedan, due for a world premiere at the New York Auto Show on April 1.

Naturally, as with all teaser sketches, they’re a bit on the optimistic side – heck, the Optima here looks more aggressive than the Geneva Motor Show Sport Space concept that hinted at the design direction for the mid-size sedan as well as a possible estate addition to the range.

What we’ll take from these official renderings is the more sculpted sides and the pronounced wheel arches together with the more angled rear window and a glasshouse that has a strong resemblance to the current model that was introduced at the 2010 NY Auto Show.

The only piece of information we get from Kia is that the new Optima was “passionately designed and obsessively crafted”.

We do know that it will share its platform with the latest Hyundai Sonata, so it should offer a similar engine lineup in North America, including a 1.6-liter turbo, a 2.4-liter naturally aspirated four and a 2.0-liter turbocharged unit.
