Motoring.com of Australia recently received an update that once again reaffirms Mercedes-Benz’s rumored return to the use of the straight-six. Past reports from Automobile, AutoCar, and Germany’s AutoBild have all echoed the same plans for the return of the classic gasoline Mercedes-Benz straight-six.
In the latest follow-up, which also reflects on the aforementioned past reports, the new inline-six will come in both naturally-aspirated and turbocharged forms, beginning with the next-generation E-Class and SL-Class. The first would be the 2016 or 2017 Mercedes-Benz E-Class. The S-Class will most likely receive the same engines as well.
Motoring mentions displacement figures ranging from 2.2L to 3.5L while diesel motors are also expected, but nothing is known about those either. But either way, the new sixers will be based off of the four-cylinder turbo mills from the current A-Class lineup.
