Na minha opinião ainda não há hibrídos de outras marcas (por ex BMW, MB, Audi and so on) porque pura e simplesmente ainda não têm qualquer interesse comercial para a marca.
Quando o imposto sobre o CO2 produzido à saída do escape do carro começar a doer a sério e quando o factor consumo começar a pesar mais na compra de carros destas e de outras marcas, os tais protótipos aparecem.
P.S. Há muita gente que fala de híbridos como se de uma nave espacial se trata-se e mais ninguém para além da Toyota e Honda conseguem tal feito...aliás as outras marcas só conseguem fazer protótipos, ainda não passaram daí...ou talvez ainda não int€r€ssa passar dessa fase[

"De acordo com a revista norte-americana «BusinessWeek», a Mercedes poderá lançar o S 400 BlueHybrid, na Europa, já em Junho do próximo ano. Caso se confirme, o topo de gama Alemão será o primeiro veículo do mundo a estar dotado de um sistema de baterias de iões de lítio.
Associado ao propulsor eléctrico, estará um motor a gasolina 3.5 V6, que em conjunto desenvolvem uma potência total de 299 cavalos e 375 Nm de binário máximo. Segundo a Mercedes, os consumos saldam-se nos 7,9 litros aos cem (10,3 litros na versão a gasolina), enquanto que as emissões ficam-se pelos 190 g/km. Quanto a performances, acelera dos 0 aos 100 km/h em 7,3 segundos e atinge os 250 km/h de velocidade máxima (limitados electronicamente).
Naturalmente que este compendio de tecnologia terá um custo adicional. Segundo a publicação norte-americana, a diferença de preço entre a versão normal e o híbrido será inferior a 10.000 euros, reduzido a um valor inferior nos mercados que a fiscalidade privilegia a redução de emissões como Portugal."
Até agora os híbridos poluiam mais, gastavam mais, bla bla bla. Depois de uma marca germânica lançar um acabam esses problemas todos e passa a ser a salvação do mundo.

O próximo é o M Hybrid e não será, ao que parece, um mild hybrid como este S, tendo um funcionamento semelhante ao Prius/HCH, podendo circular em modo 100% eléctrico.
Li isso em qualquer blog automóvel, já não sei qual [

Refiro-me aos números, mesmo. O binário total é idêntico ao 1.8 (com a vantagem de não teres que esperar pelo regime ideal do motor térmico)[

Nem é suposto. Basta que aumente o rendimento.[

Vocês também não se contentam com nada, então o carro gasta menos 23% que o equivalente não híbrido e ainda acham que não foi um passo em frente.

Com o Honda Civic e o Prius ninguém ve coisas positivas...
Mas o Lexus LS600h tem estado a ganhar terreno. Compararam no mesmo trajecto este com o A8 6.0 e no final ao abastecer 19l no Audi e apenas 11 no Lexus...
Agora a Mercedes vai começar a "onda hibrida"...
Acho que vai haver muitas pessoas a mudar de opinião... :sh)

Por falar em Lexus LS600h, aqui ficam algumas das suas características comparativamente às do Mercedes:
motor térmico: Mercedes 3.5 V6, 299 cv e 375 Nm
Lexus 5.0 V8, 394 cv e 520 Nm
motor eléctrico: Mercedes 20 cv
Lexus 221 cv
performances: Mercedes 0 aos 100 km/h em 7,3 segundos
Lexus 0 aos 100 km/h em 5,5 segundos
depois de ver estes dados ainda fiquei com a dúvida de qual dos dois será tecnologicamente mais avançado, pois um tem uma assistência e de 20 cv e o outro de 221 cv sempre são 11 x mais, o que é que acham ?

Green Car Congress: Daimler Will Launch Mercedes-Benz Mild Hybrid S 400 in Summer 2009
Citar:
Daimler will launch its first hybrid-drive passenger car model—the Mercedes-Benz S400 BlueHYBRID (earlier post)—in the summer of 2009. The S 400 hybrid is one of seven hybrid models Daimler announced in September 2007 that will be rolled out over the next few years.
The S400 BlueHYBRID combines a modified 3.5-liter V6 gasoline engine that delivers 205 kW (279 hp) of power with a 120V, 15 kW electric motor and a starting torque of 160 Nm (118 lb-ft) of torque. The combined system delivers power of 220 kW (299 hp) and a combined maximum torque of 385 Nm (284 lb-ft), with fuel consumption of 7.9 L/100km (30 mpg US) and CO2 emissions of 190 g/km.
The S 400 BlueHYBRID accelerates from zero to 100 kph in 7.2 seconds, and has an electronically governed top speed of 250 kph (155 mph). The fuel consumption betters that of the conventionally powered S 350 by up to 2.2 liters per 100 kilometers. CO2 emissions are reduced by 21%.
The S 400 BlueHYBRID is the first series-production model to be equipped with a Li-ion battery. Continental and Johnson Controls-Saft (JCS) are teaming on the pack, with JCS is providing the cells. Continental is the pack integrator and will also supply power electronics: the inverter and the DC/DC converter. (Earlier post.)
The new Mercedes-Benz S 400 BlueHYBRID is based on the S 350, and features an extensively modified drive train. This encompasses a further development of the 3.5-liter V6 gasoline engine, the additional magneto-electric motor, a 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary operating and control electronics, the transformer and a high-voltage lithium-ion battery.
The compact hybrid module is a disc-shaped electric motor that also acts as a starter and generator. The hybrid module also has a start/stop function, and supports regenerative braking.
The lithium-ion battery not only stores energy for the electric motor, but is also connected to the 12-Volt onboard network via the transformer to supply power to other standard consumers such as the headlamps and comfort features. The newly designed battery system consists of the cell block with its lithium-ion cells and the cell monitoring system, the battery management function, the high-strength housing, the cooling gel, the cooling plate, the coolant feed and the high-voltage connector.
The 3.5-liter V6 gasoline engine with variable valve control makes use of the advantages offered by the Atkinson principle, where the expansion phase is longer than the compression phase. The intake valve is kept open slightly longer between the intake and compression phases, which improves the engine’s thermal efficiency while reducing the specific fuel consumption and untreated emissions. A new cylinder head, different pistons and a modified camshaft with different camshaft control increase the output by 5 kW (7 hp) to 205 kW (279 hp) while reducing fuel consumption at the same time.
On rural journeys and on highways, the S 400 BlueHYBRID achieves a further efficiency improvement by moving the operating point of the gasoline engine to produce a lower specific fuel consumption. The extremely high start-off torque made possible by the boost effect of the electric motor gives the driver a strong feeling of powerful acceleration, while fuel consumption and emissions are reduced.
The current converter is located in the space formerly occupied by the starter. As the control electronics heat up as a result of electric currents measuring up to 150 amps, the system is equipped with its own, additional low-temperature cooling circuit.
Mercedes-Benz engineers placed the transformer in the right front wheel arch, where it facilitates the exchange of energy between the 120-Volt high-voltage network and the 12-Volt onboard network, and also allows the option of emergency starting with jump leads if the standard battery should lose its charge. To ensure a consistently high level of electrical efficiency, the transformer is likewise cooled by a low-temperature circuit.
The 12-Volt lead/acid battery is installed in the trunk, and not only supplies the standard consumers but also the monitoring system for the high-voltage components with energy. Because of its interaction with the lithium-ion battery, it is smaller in size and lighter than usual.
Mercedes-Benz developers also adapted the 7G-TRONIC automatic transmission to suit the hybrid drive, with newly programmed software for the transmission management system. A newly developed auxiliary oil pump ensures reliable lubrication of the transmission even during phases when the internal combustion engine is switched off.
This system is managed by the modified high-performance engine control unit. This unit distinguishes between operating conditions such as city traffic, rural journeys, highway driving or slow manoeuvring.
The driver is also able to monitor the status of the hybrid drive system visually. The instrument cluster has a separate, centrally positioned, display showing the energy flow during boost and recuperation phases, as well as the battery charge status.
The hybrid technology of the S 400 BlueHYBRID is equipped with an extensive 7-stage safety concept:
1. All the wiring is color-coded to eliminate confusion, and marked with safety instructions. This prevents assembly errors in production, and makes the regular quality checks easier to carry out.
2. Contact protection for the entire system by means of generous insulation and newly developed, dedicated connectors.
3. A package of safety measures for the Li-ion battery. This battery is accommodated in a high-strength steel housing, and also secured in place. Bedding the battery cells in a special gel effectively dampens any jolts and knocks. There is also a blow-off vent with a rupture disc and a separate cooling circuit. An internal electronic controller continuously monitors the safety requirements and immediately signals any malfunctions.
4. Separation of the battery terminals, individual safety-wiring for all high-voltage components and continuous monitoring by multiple interlock switches. This means that all high-voltage components are connected by an electric loop. In the event of a malfunction the high-voltage system is automatically switched off.
5. Active discharging of the high-voltage system as soon as the ignition is switched to “Off”, or in the event of a malfunction.
6. During an accident, the high-voltage system is completely switched off within fractions of a second.
7. The system is continuously monitored for short circuits.
The additional weight of the overall system is only 75 kilograms (165 pounds), including the comprehensive safety systems. Payload remains unchanged at 595 kilograms (1,312 pounds).
The S 400 BlueHYBRID is produced at the Sindelfingen plant, together with the other S-Class models. The gasoline engine, 7G-TRONIC automatic transmission and electric motor are first put together to form a hybrid module, then delivered to the production line as a unit. The market launch in western Europe is planned for June 2009; China is expected to follow in August 2009 and the USA in September 2009.
