The high-performance Sport variant of the All-New Genesis G80 is expected to be released soon. The new G80 Sport is a model that emphasizes performance and driving dynamics, and will use a high-performance variant of the 3.5-liter Twin Turbo engine.
It replaces the existing 3.3 Turbo-based G80 sport as well as the 5.0-liter V8 model sold in overseas markets. The all-new G80 Sport will be equipped with a 3.5-liter gasoline twin-turbo engine. It’ll have a maximum output of 420 horsepower and a maximum torque of 57.0 kgm, and is combined with an 8-speed automatic transmission.
The original 3.5T has a maximum output of 380 horsepower on the G80 as well as a maximum torque of 54.0 kgm, 40 horsepower and 3.0 kgm difference, which is close to the V8 engine. The Genesis G80 was sold in the North American market with a line-up of 3.8 gasoline, 3.3 turbo, and 5.0 gasoline. The G80 Sport is expected to unleash the strength of the new platform in terms of driving performance.

For the recently discontinued G80 5.0 model, a 5.0-liter V8 gasoline engine is applied, resulting in a maximum output of 425 horsepower and a maximum torque of 53.0kgm. The 3.5T engine has a strong low-rotation torque, allowing for a comfortable ride.
The 3.5 turbo engine is equipped with two turbochargers, dual fuel injection injection (PFI + GDi), central GDi injection, low friction cylinder, integrated thermal management (ITMS), and water-cooled intercooler. In particular, by applying a water-cooled intercooler, it is easy to maintain the cooling performance in summer or in limit driving, so performance can be maintained.

2 commentsHopefully that means the G70 will get this version of the engine as a top model as well, allowing them to compete with the M3, S4, and AMG C43.
Come on. This is some amateur level photoshop. Max and 420 don't even line up correctly.
