* Stuttgart - Details about a new family of engines, complete with support for electric turbocharging
--- Mercedes offered a car with one under the hood. The new 3.0-liter M256 motor is expected to produce upwards of 300 kW (408 hp) and 500 Nm (369 lb ft) of torque, compared to the 245 kW (333 hp) and 480 Nm (354 lb ft) on offer in the current M276 — which is a V6 that's been in service since 2010. In spite of the extra power, the new engine should also be around 15 percent more efficient than the current offering, and an integrated particulate filter makes it much cleaner as well... Interestingly, M256 is one of the first engines to make use of an electric turbo. Unlike a regular turbocharger, which is reliant on exhaust gas to spin up and provide a power boost, the Mercedes electric turbo can spin up to 70,000 rpm in just 300 milliseconds, offering a big shove in the back with almost no perceptible lag. It's driven by a new 48V electrical architecture, which also serves as an alternator and feeds high-draw elements like air conditioning and the starter motor... The new engines will make their debut in the 2017 Mercedes S-Class...
