For the past two years at the SEMA show, the folks at Bisimoto Engineering have taken one of Hyundai's models and tuned it up to levels of power previously unimaginable. It started in 2012 with a 600-horsepower Elantra GT, and they outdid themselves last year with a 1,000-hp Genesis Coupe. This year Bisimoto's tuners are teasing their latest wild creation by starting with a normal 2015 Sonata and turning the wick up to 708 hp thanks to a long list of engine mods.
The key in this massive injection of power is taking the regular 2.4-liter Theta-II four-cylinder engine and doing everything necessary so that it can actually withstand so much additional strain. That means introducing forged pistons and connecting rods and an improved valvetrain with new cams, plus a high-boost turbocharger to really up the ante. It's all then mated to a six-speed manual to get things rolling.
"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 of Bisimoto Engineering in Hyundai's release.
While it might be pretty cool to find a 708-hp Sonata that looked completely stock at first glance, this is for the SEMA show after all, and it's all about showing off there. So in addition to the huge increase in horsepower, the Hyundai gets a complete aero upgrade, a coil-over suspension and a roll cage inside, in addition to other improvements. At the moment, only the rear of the car is being teased ahead of the November 4 reveal.
