Infiniti's->ke36 strong sales performance in recent years has given the automaker reason to look forward to bigger things. And apparently, those bigger things equate to a pair of new vehicles added to its lineup.

Talking to Car and Driver, Infiniti's new president Johan de Nysschen is looking at the possibility of strengthening its lineup with the addition of a new flagship sedan that de Nysschen describes as an "upscale, very emotional, high-performance luxury sedan." Basically, he's looking at the possibility of developing a flagship sedan that will follow a different formula and not march to the beat of the industry.

So what does that mean, exactly? That's the question on everyone's mind, and understandably so because not a lot of people seem to have a clear grasp on what Infiniti is planning to do. The most ideal comparison as far as a unique flagship sedan that didn't follow a certain design script is the Porsche Panamera. A fastback model has been thrown around, according to Car and Driver, which seems to lend to the suggestion that if and when Infiniti decides to introduce a new flagship sedan->ke142 to the world, it's going to take a different approach on its design.

Equally compelling news is consideration being put on also building a high-performance coupe based on the platform of the aforementioned flagship sedan. That's a pretty exciting development, considering Infiniti is lacking that kind of poster-worthy sports car->ke506 that other automakers have.

If there's a chance to introduce a pair of new and exciting models that will take the Japanese automaker to another level, Infiniti should jump at the chance of building on its sales momentum.

Click past the jump to see a couple of Infiniti concepts that have been introduced in recent years

Infiniti Essence

The Essence was introduced back in 2009 in concept guise as a celebratory model to commemorate the company's 20th anniversary. Designed in collaboration with Louis Vuitton, the Essence Concept was a bonafide eye-catcher. It also featured a hybrid system that combined a petrol engine with an electric motor that can reach an output of 592 horsepower when both engines are in full blast.

Infiniti Etherea

Despite being designed in hatchback form, the Etherea Concept still has the size to make for a good inspiration for whatever models Infiniti decides to build in the future. It also came with a supercharged 2.5-liter four-cylinder engine that translates to an output of 245 horsepower and is mated to a hybrid drive system and piped through a continuously variable (CVT) transmission.

Infiniti LE

One of the newest concepts out of Infiniti is the LE, which was introduced at the 2012 New York Auto Show. It's about the same size as the G Sedan and has been touted as Infiniti's entry into the zero emission luxury sedan market.
