Hyundai teams up with tuner Bisimoto Engineering to create a 708hp Sonata for the 2014 SEMA show in Las Vegas. Bisimoto is confident that this is the most powerful Sonata ever.

They used a combination of strengthened internal components from forged pistons to rods to high-revving valve train and camshafts, a high-boost turbocharger and a fast burning, flex-fuel diet to achieve the power. This is what they said:

"Outrageous power is nothing without reliability, and it was a firm goal to retain the reliability that Hyundai is known for," said Bisi Ezerioha, owner and chief engineer, Bisimoto Engineering. "After hundreds of hours of testing, failure analysis and prototyping, 18 new products will be engineered and produced in house to produce 708 horsepower from the Sonata."
