A V10 petrol engine and three electric motors work in it together, which come to a system output of 910 hp. If the top speed of other plug-ins is often reduced to values ​​around 120 km / h, taking into account the battery charge, consumption and range, the Asterion and Lamborghini are worthy of over 300 km / h. The manufacturer specifies the consumption at 4.1 liters. The undercuts…

Manufacturers of cars with large engines need to be creative to meet CO2 limits. The plug-in hybrid drive is also a must for Mercedes. Allegedly without sacrificing performance.

D.he car manufacturers currently have one problem in common: by 2020 they will have to reduce the average carbon dioxide emissions of their vehicle fleets to 95 grams per kilometer and less – otherwise the EU could face fines worth millions.

Two years ago, Volkswagen boss Martin Winterkorn announced that a number of models in the group would be equipped with plug-in hybrid drives to solve the problem. The Golf GTE will be launched on the market at the turn of the year, the Passat with charging cable and the drive combination of combustion engine and electric motor has been announced for the coming year. And Porsche already has models on sale.

If it is comparatively easy for brands like VW or Fiat, the challenge for manufacturers of passenger cars with large and more fuel-thirsty engines is greater. That is why it seems almost overdue when Mercedes announces an offensive in the direction of plug-in hybrids. “By 2017 we will be bringing around ten models with this technology, one every three or four months,” says Development Director Thomas Weber.

Boom expected in the upper class

It starts with the S-Class, followed by the C- and E-Class and off-road vehicles. Even convertibles and coupes are prepared. “In a few years, the technology will be as natural as a gasoline or diesel engine is today,” he says.

Mercedes is already calculating six-digit numbers by the end of the decade. Weber does not want to commit himself much more precisely. But experts assume that luxury car manufacturers may have put every third car on a leash by 2020.

For Weber, the fact that partial electrification should not mean a waiver of the usual opulent appearance of the models from Stuttgart is an important message.

Mercedes customers, including frequent and company car drivers, should be reassured by this statement, as is the data on the S-Class with the corresponding technology, which is on sale these days for at least just under 108,950 euros: a V6 engine, the electric motor, works under the hood is integrated in the gearbox, the battery is located in the trunk and can also be charged from the socket.

Hardly any compromises in terms of performance

"Driving performance like an eight-cylinder, fuel consumption like a four-cylinder and zero emissions on long journeys," promises Weber. With one battery charge, the flagship can drive up to 33 kilometers purely electrically. The S 500 plug-in hybrid has a system output of 442 hp, accelerates from 0 to 100 in 5.2 seconds with a maximum torque of 650 Newton meters (Nm) and reaches 250 km / h.

It is almost on a par with the conventional S 500 with a 4.7 liter V8 engine that the Swabians are offering at the same price. Only that the plug-in consumes less in the standard cycle than a Smart: 2.8 and CO2 emissions of 65 g / km are in the data sheet of the luxury liner. To be fair, it must be said that everyday consumption is usually much higher. This is especially true when the combustion engine has to do double the work by providing propulsion and charging the battery at the same time.

What counts for the specifications from Brussels, however, is the driving cycle according to ECE standard R101 for hybrid vehicles, which results in the low standard values, and thus the power cable of the plug-in hybrid becomes a lifeline for the luxury class. "Without a breakthrough for the plug-in, we will not achieve our CO2 targets," says Weber, Head of Development.

The same applies to the manufacturer Audi, which has the first socket hybrid on the starting line with the A3 Sportback e-tron, or to the manufacturer BMW, which also wants to convert the X5 accordingly after the i8. And Porsche has so far put the Cayenne and Panamera on a leash. The competition will also have to follow suit in order to meet the political requirements.

Flexible architecture makes it possible

Because the development of the market is difficult to predict, the greatest possible flexibility is required: Which models, which markets, which quantities – you have to be able to react very spontaneously, says Weber, relying on a modular system that his team equipped at an early stage.

More than five years ago, when luxury models like the S-Class were branded as dinosaurs and already written off, they designed the architecture in Stuttgart that now gives them all options – including the alternative drives. That was active old-age provision: "If you can’t build on such flexible platforms today, you won’t be able to cope with the future," Weber is convinced.

Implementing such a program technically is only one side of the coin. On the other hand, there are costs: with a plug-in hybrid like the S 500, you can save two cylinders and install a smaller engine. But to do this, you put expensive components in the car that more than eat up the price advantage: an e-machine, power and charging electronics and a battery.

But Weber no longer wants to apply the mockers’ formula “good for conscience, bad for business”. "Every one of our hybrids is already making a profit today," he says. This is still limited, but the so-called economies of scale increase with the number of units, and the individual components can be bought more cheaply.

Haptic accelerator pedal is supposed to raise lead feet

Weber also relies on advances in battery technology. Cheaper rechargeable batteries could be installed in the future or, optionally, larger batteries for a longer electrical range could be offered at the same price. "In the medium term, the plug-in models will bring in the same ten percent return that we want to achieve with all other cars."

The kit is well stocked and the costs are obviously under control – now all you have to do is get the sales figures right for Weber’s equation to work out. But the board is not worried about that. It is true that customers would have to relearn a little while driving. Because if you just step on the gas bravely, you will not achieve low consumption values ​​even with a plug-in hybrid.

Weber wants to give its customers a little help with predictive assistance systems so that the advantages of socket cars can be better realized. This includes a haptic accelerator pedal, which is supposed to teach lead feet wrong with gentle counter pressure.

Prominent works drivers should also work to convince them: The fact that Lewis Hamilton and Nico Rosberg are currently so successful in Formula 1 is also due to the fact that they have their hybrid Mercedes so well under control.
