An image showing the concept version of Kia’s upcoming VG luxury sedan has leaked to the web ahead of its unveiling at the Seoul Motor Show next month. Dubbed the KND-5, the concept hints at what we can expect from the company’s new Amanti replacement which will officially debut later this year.

Created to rival other near-luxury sedans such as the Volkswagen Passat CC, the new KND-5 concept boasts an elegant exterior which features upscale design touches such as LED lighting, 20-inch wheels, and a massive panoramic glass roof.

The Kia KND-5 concept is roughly the same size as the current Kia Amanti, measuring 4945mm long, 1850mm wide and 1475mm high. The concept car is built on a newly developed front-wheel-drive platform with a wheelbase of 2845mm.

Perhaps the most interesting information about this near-production concept vehicle is the engine unit displaced under it’s hood. According to Kia’s official Korean press release, the KND-5 concept features a 3.5L V6 Lambda engine!

Designed under the guidance of Peter Schreyer, the KND-5 concept previews Kia’s upcoming near-luxury sedan, code-named VG, which spy pics have been seen quite oftenly on the web lately. The 2010 Kia VG will share it’s FWD platform with the next gen Hyundai Azera (codenamed HG) and is scheduled to make it’s official Korean debut in September this year.

The KND-5 concept, will be put on display at the Kia’s booth at Seoul Auto Show alongside next generation, 2010 Kia Sorento and Kia Forte hybrid electric vehicle, the world’s first hybrid car to be powered by LPG (Liquefied Petroleum Gasoline) and applied with lithium polymer (Li–poly) batteries.
