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.
