Mercedes to debut new efficient gas engines in 2017
In contrast to petrol and diesel, gas engines should be with us for the foreseeable future, so car makers are working hard to find ways to maximise efficiency as opposed to completely focusing entirely on electric vehicle technology.
On two of the three new engines soon to be released, both the starter and alternator have been swapped for more powerful variants. This will result in smoother operations on stop-start systems, and also opens the possibility of switching the engine off when coasting. An electric compressor will act as a secondary turbo charger; this will help to boost pressures when at slower engine speeds. A 48-volt electric system will be the operating platform for all the new engines.
Next year should also see a petrol inline-4 introduced. It will incorporate the tech mentioned above, which will increase efficiency over the current four-banger. Twin-scroll turbochargers will help provide low-speed boost, which should see this engine capable of providing seriously potent power levels in any upcoming AMG trim.
The old V6 will be retired, and a new inline-6, with the same 3.0-litre displacement will take its place. This new engine offers V8 performance, with V6 efficiency. It offers a 15% CO2 emissions reduction over the outgoing V6, and is compatible with the new tech updates.
Last, but certainly not least is the ‘big one’ – the twin-turbocharged V8. Mercedes has projected this new engine being capable of in excess of 476 bhp, whilst consuming 10% less fuel than the older, 455 bhp V8. In addition, this new motor will also have cylinder deactivation. It will first be seen on the revitalised Mercedes-Benz S-Class, set to launch in 2017.
