In more recent years, however, the choices have been slimming down and mostly kept for the top-shelf stuff. Mercedes-Benz dropped sixes in the C-Class with the W206 redesign, but will thankfully rectify it soon. Cadillac only reserves V6 power for the CT4 in the Blackwing model.Audi still has the S5, so we're thankful for that, and the same goes for Lexus with the IS 350. Of course, we can't leave out BMW, the progenitor of the whole genre, continuing that with the M340i. Sadly, it appears that Genesis is dropping out of this race, as it's been reported that the 3.3-liter twin-turbo V6 will be dropped from the G70 lineup for 2027.Uncovered DocumentsIn a report by Car and Driver, documents from NHTSA and the EPA have hinted that the 2027 Genesis won't go on with its boosted V6. That engine is (or rather, was) known as the Lambda II RS T-GDi, and part of the Lambda engine family. This engine powered various midsize to large models, namely the previous generations of the Genesis G80 and G90, as well as the Kia K900 and Stinger.AdvertisementAdvertisementPer the publication, Genesis did not confirm the possible discontinuation of the 3.3 V6 option in the compact executive sedan, although government papers do tend to preview what to expect for the next model year. There is a modicum of good news, though, as the automaker did say that there will be further updates for the G70, dispelling rumors of its discontinuation.The Sole ChoiceThe sole engine choice will be the 2.5-liter four-cylinder turbo that also powers many within the Hyundai Motor Group. It's simply called the Smartstream G2.5T, and it's seen in models such as the Palisade, Santa Fe, and Sonata, to name a few, as well as other Kia models like the Telluride, Sorento, and K5. Genesis also uses it for the G80, GV70, and GV80. For rear-drive applications, it makes 300 hp and 311 lb-ft of torque.By the looks of it, Genesis is simply retiring that powertrain and the entire Lambda V6 family, as it's been around for over 20 years. Do remember that the company also has the newer 3.5-liter twin-turbo V6 that's available in all its models bar the G70. Dubbed the Smartstream FR G3.5T, it's for exclusive use within Genesis, although there are other variations for Hyundai and Kia. That 3.5-liter is good for 375 hp and 391 lb-ft, an improvement over the 3.3's 365 hp and 376 lb-ft rating.Should there be a next-generation G70, there's a strong chance it'll benefit from the Smartstream twin-turbo V6. That said, we're not entirely sure of a second-gen model actually happening. The G70 has been a solid, although not entirely spectacular, seller in North America. It consistently sells over 10,000 units per year, so it has that going for it, and its continued success in South Korea (a market that loves sedans) bodes well for its survival. We say it would be a waste if there wasn't a redesigned model, as it still remains one of the best compact executive sport sedans out there.This story was originally published by Autoblog on Aug 25, 2026, where it first appeared in the News section.
