Mercedes-Benz used the Frankfurt Motor Show to outline the product timeline for its introduction of a number of new hybrid models into the market beginning in 2009. The company also announced it would begin series production of a B-Class fuel cell car in 2010.
The hybrid products include the ML 450 Hybrid, a gasoline-electric application of the two-mode hybrid system co-developed with GM and BMW; the S 400 Hybrid, a gasoline mild hybrid; and four BLUETEC diesel mild hybrids, the E 300, S 300, C 300 and S 400.

The ML 450 Hybrid is a two-mode hybrid due for market introduction in 2009. The V6 gasoline engine produces 205 kW (279 hp) of power and 338 Nm (249 lb-ft) of torque, while the two-mode hybrid module with two electric motors develops 45 kW (61 hp). The end result is a combined system output of 236 kW (321 hp) and a combined maximum torque of 480 Nm (354 lb-ft), with fuel consumption of 7.7 l/100km (30.5 mpg US) and CO2 emissions of 185 g/km. A 288-V battery provides the energy storage for the motors.
The S 400 Hybrid is also due on the market in 2009. The S 400 Hybrid combines a 205 kW (279 hp) V6 gasoline engine with a hybrid module delivering from the outset 160 Nm (118 lb-ft) and 15 kW (20 hp). The combined maximum power output is 220 kW (299 hp), the combined maximum torque amounts to 375 Nm (277 lb-ft).
The S 400 Hybrid can accelerate in 7.3 seconds from 0 to 100 km/h and reach an electronically limited top speed of 250 km/h (155 mph), with fuel consumption of 7.9 l/100km (30 mpg US) in the NEFZ cycle and CO2 emissions of 190 g/km.
The compact hybrid module for the S-Class offers a boost function and start-stop function. The S-Class will use a lithium-ion battery pack from Johnson Controls-Saft.
The E 300 BLUETEC Hybrid will arrive on the market in 2010 as the first of a total of three Mercedes-Benz models to offer the combination of BLUETEC, 7G-TRONIC and hybrid technology.
The modular technology concept of the E 300 BLUETEC Hybrid consists of a new 2.2-liter four-cylinder diesel that develops 150 kW (204 hp) and a maximum torque of 480 Nm (354 lb-ft), plus a compact hybrid module delivering additional 15 kW (20 hp). With the high combined torque of 560 Nm (413 lb-ft) the E 300 BLUETEC Hybrid surpasses many 6-cylinder diesel upwards of 3 liters displacement. Fuel consumption of 5.1 l/100km (46 mpg US) corresponds to CO2 emissions of 134 g/km.
The S 300 BLUETEC Hybrid, with 560 Nm (413 lb-ft) total torque and fuel consumption of 5.4 l/100 km (44 mpg US) is also due to arrive on the market in 2010. The configuration and performance data of this engine are identical to those in the E 300 BLUETEC Hybrid. With the standard 7G-TRONIC seven-speed automatic transmission, the S 300 BLUETEC Hybrid accelerates from 0 to 100 km/h in 8.4 seconds, and can reach a top speed of 240 km/h (149 mph). CO2 emissions are 142 g/km—57 grams, or some 30%, less than the current best saloon in the S-Class segment.
The S-Class uses the version of BLUETEC with AdBlue injection system. The S 300 BLUETEC Hybrid has the potential to meet Euro 6 or the US 50-state Tier 2 Bin 5 standards.
The C 300 BLUETEC Hybrid will follow in 2011. With combined power output of 165 kW (224 hp) and a combined maximum torque of 560 Nm, the engine delivers the same performance here as it does in the S 300 BLUETEC Hybrid and the E 300 BLUETEC Hybrid. Due to its lower vehicle weight, the C 300 BLUETEC accelerates even faster (0-100 km/h in 7.2 s), while its top speed stands at 236 km/h (147 mph).
The C 300 BLUETEC Hybrid consumes 4.6 l/100km (51 mpg US), with 122 g/km of CO2. As in the E 300 BLUETEC Hybrid, the C 300 will use the combination of oxidation catalytic converter and diesel particulate filter from the version of BLUETEC with the NOx storage catalytic converter to comply with standards such as Euro 6 and Bin 5.
After 2010 Mercedes-Benz will offer a further BLUETEC hybrid combination in the form of the S 400 BLUETEC Hybrid. This hybrid combines the 15 kW (20 hp) hybrid module with the V6 diesel engine that is already used in numerous Mercedes-Benz model series. Following further development, this engine delivers top output of 180 kW (245 hp). Combined, this BLUETEC/ Hybrid unit delivers a maximum power output of 195 kW (265 hp), at a combined maximum torque of 630 Nm (465 lb-ft).
Further power combinations, such as for instance, with a 45 kW (61 hp) hybrid module, are currently in the testing phase. With 195 kW (265 hp) and 630 Nm of torque (combined power), the S 400 BLUETEC Hybrid accelerates from 0 to 100 km/h in 7.3 seconds, and this in conjunction with the standard seven-speed automatic transmission 7G-TRONIC. Its electronically limited top speed is 250 km/h (155 mph). Average fuel consumption is 5.8 l/100km (40.5 mpg US) with CO2 emissions of 154 g/km.
As in the case of the S 300 BLUETEC Hybrid, this system uses BLUETEC with AdBlue injection.
The B-Class F-Cell. Mercedes-Benz will launch its first small-scale series-production car with a fuel-cell drive—the B-Class F-Cell—in the summer of 2010. The new F-Cell will use a new generation of fuel-cell system, first introduced in the F 600 HYGENIUS research vehicle in 2005. (Earlier post.)
The redesigned stack is around 40% smaller and produces 30% more power, yet it uses 16% less fuel than its predecessor. Starting under cold conditions has also been improved with the help of innovations such as an electric turbocharger to control the air supply and a new ventilation and dehumidification system.
The B-Class F-Cell develops top output of 100 kW (136 hp) and a maximum torque of 320 Nm (236 lb-ft), offering performance on a par with that of a two-liter gasoline engine vehicle. Fuel consumption corresponds to 2.9 liters of fuel (diesel equivalent) per 100 kilometers.
