The Sonata utilises lightweight aluminium engine for significant weight saving while cylinder head and engine block are separately cooled to reduce power loss and enhance fuel efficiency. Molybdenum coating is employed for piston skirt to reduce friction (such types of coating can also be found in Infinity Indy Racing V8 engine while the 2.4L engine employs Electronic Throttle Control (e-TC)"Drive-by-Wire" for ultra-fast response by replacing mechanical cable with computer signal.

For transmission, intelligent gate-type Dual Mode Auto transmission (iDMA) conbines automatic operation with manual all rolled into one while HIVEC advanced adaptive transmission learns driver driving style and can skip gears for ultra fast response.
