Sketches show a more muscular-looking Rio that will be longer, wider and sit lower than the current model.

Kia has released some sketches of the upcoming next-generation Rio model.

The new Rio will be longer and wider, as well as sit lower, than the current model - providing more room while sleeking out the design. According to Kia, the new look of the Rio is meant to "inject emotional appeal into the B-segment" and appeal to that crucial demographic of buyers, 25 to 49 year-olds.

But it's a little difficult to reconcile the sketches seen here with the spy shots we've previously published. The sketches make the Rio look far more muscular and aggressive than the spy shots of the next-generation Rio. The sketches still look like a concept car.

Engine candidates for the Rio include the 1.8 liter producing 148 bhp (110 kW / 150 PS) and 131 lb-ft (177 Nm) of torque, likely mated to either a 6-speed manual or 6-speed automatic.

The next-generation Rio will make its debut at the Geneva auto show in March.
