The basic powertrain will likely come from the sedan which is powered by a 1.8-liter four-cylinder producing 148-hp and 131 lb-ft of torque. Hyundai is also likely to create a high performance Elantra R-Spec in 2012. This coupe will likely be powered by the same 208-hp turbocharged engine already confirmed for the high-performance version of the Hyundai Veloster. Transmission choices for the Veloster include an optional duel-clutch automatic transmission for its naturally aspirated 1.6-liter engine, so this will likely be the choice for the R-Spec Elantra.
Fuel economy will likely be around 29 MPG city and 40 MPG highway regardless of transmission, trim level and wheel size. The Elantra sedan is offered in two trim levels including GLS and Limited. Coupe equipment will likely be similar to the sedans offerings.
