An Autoblog report states that Mercedes-Benz will go all-hybrid with its next-generation S-Class lineup in the US with one exception, the enthusiast-oriented AMG models.
A source close to the project said that the cruiser is slated to arrive in 2012. The gas-only S-Class models will be the exclusive preserve of the company's performance arm. Mercedes-Benz is not open to offering both regular and hybrid variants of the same model in the US.
Currently, Daimler only offers a single gasoline-electric variant of its W221 S-Class -- the S400 hybrid, which is at the top of the range with a price tag of $87,950.
It combines a 3.5-liter V6 with a mild hybrid assist system, resulting to an output of 295hp and 26 miles-per-gallon on the freeway.
Mercedes-Benz boosted the cylinders and the power in all the models in the current S-Class lineup. This includes the 382-hp 5.5-liter V8 of the S550 and the twin-turbo 5.5-liter V12 of the S600.
It is not confirmed if company engineers will downsize the internal-combustion side of the next S' powertrain equation due to the carmaker's all gas-electric strategy.
While Mercedes is expected to offer a range of CDI diesel models in the European market, no such model is intended for the US at this time.
