Mercedes launches two new diesel S-Class models

Mercedes-Benz has announced the launch of two new, highly efficient S-Class models.

Building on the previously introduced S400 HYBRID, Mercedes is now rolling out the S300 BlueTEC HYBRID.

Unlike the gas-powered S400 HYBRID, the S300 BlueTEC HYBRID uses a small-displacement 2.2L four-cylinder diesel motor, good for 204 horsepower. The Hybrid sedan also uses a 20 kW electric motor sandwiched between the engine and transmission that provides extra boost during acceleration and can also recoup energy through regenerative braking. Mercedes says the S300 BlueTEC HYBRID can operate in electric-only mode for short periods.

Total torque for the system is a healthy 368 lb-ft.

On the European cycle, the Mercedes S300 BlueTEC HYBRID is good for 53.5mpg.

In addition to the S300 BlueTEC HYBRID, Mercedes is also introducing the S350 BlueTEC 4MATIC, which is essentially an all-wheel drive version of the S350 BlueTEC. Like its two-wheel drive counterpart, the S350 BlueTEC 4MATIC uses a 258 horsepower, 457 lb-ft of torque version of Mercedes’ 3.0L V6 turbo diesel.

Although not a thrifty as the S300 BlueTEC HYBRID, the S350 BlueTEC 4MATIC returns a compact car-like 40mpg on the European cycle.

Both diesel S-Class models can be had in short- and long-wheelbase forms. Pricing for the S300 BlueTEC HYBRID will start from €80,920 ($109,200), while the S350 BlueTEC 4MATIC will carry a base price of €84,728 ($114,365).

Mercedes hasn’t confirmed either model for the United States, but it is thought that the S350 BlueTEC 4MATIC will eventually be sold on these shores.
