The recently released Mercedes-Benz S-Class is a technological tour de force, and one most consider a stand-out example of best practice fuel economy and emissions with respect to its size. But Mercedes says that even more can be done, and that its next-gen S-Class, due later this decade, will feature not only those electronic, safety and infotainment technologies expected at the time, but also a comprehensive repertoire of environmentally-focussed improvements.
Speaking at a press gathering at the Geneva motor show last week, Mercedes-Benz S-Class Chief Engineer, Dr Hermann-Joseph Storp, said the German manufacturer is already looking at ways to lessen the S-Class’ eco footprint, and that every aspect of the vehicle will face exhaustive engineering scrutiny.
“We are starting now to think about what will come up for the next-generation of S-Class, we say ‘OK, what can be the next step?” explained Dr Storp. “It may be that the next S-Class has more aluminium, or aluminium combined with plastics [CFRP], for example.”
Carbon-fibre reinforced plastics are currently utilised in a limited capacity in production vehicles, while aluminium is becoming increasingly mainstream. Like the S-Class, the new Mercedes-Benz C-Class has already seen a significant escalation in the amount of aluminium used in the construction of its body, rising from a little more than 10 per cent in the previous generation, to almost 50 per cent in the current model. “It’s one discussion we have with weight; the other is stiffness for the body, and reducing noise,” Dr Storp continued. “[The] reduction of weight, CO2 reduction, the combination of [a] combustion engine with plug-in electrical power, new batteries... and drag coefficient – to reduce it as far as we can – will again help [the new S-Class].”
The current S-Class boasts fuel economy reductions of as much as 20 per cent when compared to the outgoing model, and is available with an ultra-frugal diesel-electric hybrid version dubbed S 300 BlueTEC Hybrid. It is said to consume 4.5L/100km on the ADR Combined cycle, with CO2 emissions of 118g/km. Just how much further Mercedes-Benz can push the envelope is indeed an exciting prospect, especially when considering mainstream petrol-electric hybrid models weighing nearly half as much as the S-Class are consuming only 0.6L/100km less.
The most frugal of the current Mercedes-Benz S-Class variants, the S 300 BlueTEC Hybrid, is due to go on sale locally next month (April) and will be priced from $195,000 (plus on-road costs).
