Hyundai will be getting rid of the 4.6-liter V8 in the Genesis sedan for 2013. But don't worry, they're not abandoning V8s.

As of the 2012 model year three engines are available in the updated Genesis sedan. There's the new 3.8-liter V6 producing 333-hp, the 4.6-liter V8 making 385-hp and the big boy R-Spec 5.0-liter V8 that cranks out 429-hp. According to a series of tweets by InsideLine Senior Editor Erin Riches, Hyundai has complained that the 4.6-liter is too costly to re-certify for emissions. While unconfirmed, the assumption here is that the 5.0-liter could be offered in a detuned form for standard models, or that the current R-Spec version with 429-hp will become the new base engine with an even more potent R-Spec for 2013.

Look for AutoGuide's review of the new 2012 Hyundai Genesis R-Spec to drop on Monday.
