Mercedes-Benz will make a return to the inline-six-cylinder engine game, according to a report from the UK's AutoCar. It's not clear what's prompting the phasing out of the current array of V6s.
We'll see the first inline-six from Mercedes in next-generation E-Class, set to debut in 2016. Following that, it'll arrive as part of a mid-cycle refresh for the C-Class in 2017. What's particularly special about the new inline-six is its modular nature, which will allow Mercedes to eventually spinoff three- and four-cylinder options, with the three-pot arriving alongside the new inline-six.

No word on n/a or f/i, but I'll bet they are working on a direct competitor to the N55.

Mercedes-Benz has used straight-six engines in its cars for around 100 years, starting in the first decade of the 20th century with a monstrous 10 L (610 cu in) engine producing 75 hp (56 kW), and producing in parallel through the World War I years the majority of German aviation engines of straight-six layout, culminating in the Mercedes D.III engine series of 1916-18 for the Luftstreitkräfte. Before and after the merger of Daimler and Benz in 1926, the combined company produced a variety of powerful straight-six engines, culminating in a 7 L (430 cu in) supercharged unit producing up to 300 hp (224 kW). Mercedes-Benz began the post-war era by producing straight-fours, but resumed making straight-sixes in 1951 with the M130, which was the beginning of the modern era of MB straight-sixes. Following that introduction, the company produced two lines of petrol (gasoline) straight-sixes at any one time, a small six and a larger six, in addition to its straight-fours, straight-fives, and later V8s and V12s. Although the company has used diesel engines in its cars since 1934, it introduced its first straight-six OM603 a 3.0 L (180 cu in) diesel in 1985. In 1996, the company replaced its petrol straight-sixes with a series of 90° M112 V6s, although it continued to produce diesel straight-sixes.
