There is even better news for the 2023 Genesis G90 – at least, for those who believe that more power is always better. The South Korean brand is bringing to our market the standard-wheelbase flagship sedan, announced with a 3.5-liter twin-turbocharged V6, an upgrade from the current sedan 3.3-liter twin-turbo V6. The 3.5 G80 sedan produces 375 horsepower and 391 pound-feet of torque, giving the numbers an improvement of at least 10 ponies and 15 pound-feet. In its home market, Genesis sells a long-wheelbase G90 with a length of 7.5 inches and is available with a 3.5-liter version that is supercharged and fitted with a 48-volt light-hybrid system. Cars and drivers Reports that this engine is also running here.
According to the Genesis South Korean site, the engine produces 409 hp and 405 pound-feet of torque in that market. However, the document Genesis submitted to the US EPA shows that 420 hp horsepower is listed for a trim called G90 MHEV. The horse’s number is probably not an accident, as it matches the output of the optional 5.0-liter V8 available in the 2022 G90. From a supercharged 3.5-liter twin-turbo, the torque exceeds the 5.0-liter by about 20 lb-ft.
Despite the power disparity between the 203 G90’s 3.3-liter and 5.0-liter and the 2023 G90’s two 3.5-liter variants, it doesn’t have much of a fuel economy difference when comparing AWD trims, as it is the only drivetrain that the G90 MHEV will do. Offer EPA lists 3.3-liters as 17 miles per gallon in the city, 24 on the highway and 20 combined. 5.0-liter rated 16 cities, 23 highways, 18 together. The Mild Hybrid is more economical with its gas than the 3.5-liter 5.0-liter, rated 17 cities, 24 highways and 20 together. To close the circle, the 2023 G90 non-hybrid displays slightly better than 18 cities, 26 highways, 21 combined supercharged mild-hybrids, including the 3.5-liter V6.
The sedan is scheduled to reach dealers later this year and there is still a long way to go. These details, including the price, will come out in the next few months.
