Hyundai Equus, Genesis Sedan to Get New 429-Horsepower 5.0L V-8

According to our sources in South Korea, Hyundai is developing a new 5.0-liter V-8 Tau variant that will see duty in both the upcoming flagship Equus sedan as well as revamped version of the current Genesis sedan. With 429 horsepower and 376 pound-feet of torque, the new engine’s output is impressive to say the least.

The new engine is expected to arrive in early 2011 in the 2012 models, replacing the current 375-horsepower 4.6-liter V-8, which will no longer be offered. While the new 5.0-liter engine shares the same architecture with the current mill, its direct-injection technology, a bore increase, and a compression ratio bumped to 11.5:1 all help account for the estimated performance advantage. An eight-speed automatic that was designed and built in-house at Hyundai will be paired to the engine for maximum efficiency, helping to bump fuel economy roughly 1 mpg to just over 26 mpg (8.9 liters/100km) despite the new engine’s increased power.

Hyundai will be also likely be bringing a new 3.3-liter direct-injected V-6 to the U.S. that puts out 282 horsepower and 254 pound-feet of torque. It, too, will come with the new eight-speed automatic and is likely to replace the current 3.8-liter V-6 found in the Genesis and Genesis Coupe.

We’ll bring more information on both engines as it becomes available.
