Fountain Valley, California - What you are looking at, according to custom tuner Bisi Ezerioha, is the most powerful Hyundai Sonata ever built.
How powerful? Try 522kW from a 2.4-litre Theta II four-cylinder mill.
Ezerioha is the head honcho at Bisimoto, which specialises in extracting huge power from Hyundai engines, while keeping them reliable enough to run on the street - like the 750kW Genesis Coupe Bisimoto built for the 2013 Specialty Equipment Manufacturers Association show in Las Vegas.
This Sonata is Bisimoto's third SEMA co-production with Hyundai, and it'll make its public debut at Hyundai's media conference at the show on 4 November.
HOW'D THEY DO THAT?
