Kia may be planning a V8 upgrade for its Stinger sedan.

Kia is reportedly developing a high-performance version of its upcoming Stinger sedan with a V8 engine. That news comes by way of Kevin Hepworth, who is general manager of media and corporate communications for Kia Australia. "I believe they're developing one," Hepworth told CarAdvice, referring to a V8 engine option for the Stinger. "There may be a possibility the U.S. could pick it up."

As it stands, the top engine option for the Stinger, which will go on sale either later this year or early in 2018, is a twin-turbocharged 3.3L V6 rated at 365 horsepower and 376 lb-ft of torque. Kia says that's enough grunt to get the Stinger from 0-60 in 5.1 seconds.

The Stinger V8 would presumably use Hyundai's 5.0L Tau motor. Under the hood of the Genesis G90 that engine makes 420 horsepower and 383 lb-ft of torque. However, its possible that Kia could increase the V8's output for duty in a high-performance Stinger that would essentially serve as a cheaper alternative to the Mercedes-AMG C63. Look for the Stinger's 0-60 time to drop significantly if Kia drops a V8 between its front fender.

Kia hasn't announced anything official about a Stinger V8, but it's a development we'll be sure to monitor.
