Mercedes S 350 ECO Start Stop
Like we said earlier, this year is the year of start/stop system! It is being offered in almost any type of cars from small hatchbacks to large SUVs and now even in a luxury sedan as Mercedes S Class.
To make its S350 BlueTEC diesel even more economical, Mercedes has launched a new edition equipped with a sophisticated ECO start/stop system. It works as it should just like any other system of this sort and shuts the engine down when you are stationary and restarts it when you want to move away, but it’s been refined for maximum smoothness of the operation and the fastest restart.
With this system, this big Mercedes manages to do 6.0 liter per 100 km with CO2 emissions of 164 grammes per kilometre. And it’s not like there has been any compromise on luxury and performance either.
The car makes 190 kW (258 hp) and 620 NM of torque which is easily enough for smooth overtaking and everyday driving needs. But because of all this economy considerations, the price of the car is a bit high to be honest.
You have to pay 76,517 euros for it. That is unchanged from last year which means you get the ECO Start Stop for free, but still it is a lot for a diesel!
Details can be found in the press release below:
With immediate effect, Mercedes-Benz is combining the V6 diesel engine in the S 350 BlueTEC with an ECO start/stop function. As a result, the fuel consumption of the luxury class saloon has been brought down to 6.2 litres per 100 kilometres (NEDC combined). The S 350 BlueTEC is also one of the world’s cleanest diesel models.
The V6 diesel engine in the S 350 BlueTEC develops an output of 190 kW (258 hp) from a displacement of 2987 cc, and generates 620 Nm of torque. It also comes with excellent fuel consumption and emission values as standard. Thanks to BlueTEC with AdBlue® exhaust treatment, the S-Class model – which made its debut in 2010 – currently already fulfils the emission values planned for 2014 in accordance with the EU6 standard, and as such is one of the world’s cleanest diesel vehicles. The new ECO start/stop function fitted as standard now helps to improve the efficiency of the luxury class saloon even further. With a combined consumption of 6.2 litres of diesel per 100 kilometres, the S 350 BlueTEC improves on the figures of its predecessor by 0.6 litre, or nine percent. CO2 emissions have dropped from 177 to 164 grammes per kilometre.
The ECO start/stop system developed by Mercedes-Benz switches the engine off when the vehicle comes to a standstill – for example at traffic lights. The engine then immediately starts again as soon as the driver takes his foot off the brake pedal. Thanks to the intelligent control system, all of the vehicle’s functions and comfort systems continue to operate during the stop phase.
The increase in efficiency was also achieved, among other things, through the use of TWAS(twin-wire-arc-sprayed) coating technology.
AMG has been using TWAS coating technology since 2005 in the 6.3-litre V8 in all model series, including the new SLS. Based on the positive experiences gained, Mercedes has now also developed this technology further for diesel engines. It is currently being introduced in the new Mercedes V6 diesel engine.
The benefits are impressive. Taking the diesel engine as an example, the potential savings are around 3%. At the same time, the weight has been reduced by 4.3 kg.
