Hyundai sends Dodge a one-horsepower trump card

The Sonata is (now) a conservative family-mobile with great features and stellar value. Even the engines, which used to be tweaked for peak horsepower numbers, are tuned more for usable torque on the lower end.

But this one? Nope. Not this one.

Build in partnership with Bisimoto, the Sonata you see here pumps out 708 hp from its heavily-modified 2.4-liter “Theta-II” 4-cylinder engine. It makes those big numbers thanks to some high-boost turbocharging and its ability to burn ethanol as well as gasoline.+

“Outrageous power is nothing without reliability, and it was a firm goal to retain the reliability that Hyundai is known for. 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,” said Bisi Ezerioha, owner and chief engineer, Bisimoto Engineering.
