The heavily anticipated twin-turbo straight six engines from Mercedes-Benz have been a recurring subject in the automotive rumor mill since late last year, but further details have emerged about the powerplants that'll replace the current lineup of gasoline V6 offerings.
We know that the three-pointed star will switch to four platforms instead of the current nine in the near future to homogenize the model lineup and save money on R&D work. A range of modular three and four-pot engines are currently in development for those very platforms.
But the iconic inline six-cylinder will also be resurrected to propel future generation Mercedes-Benz models. At the present moment, we know that the straight-six engine lineup will replace the current V6 mills and will benefit from turbocharging technologies for added oomph and fuel economy. According to certain reports, the first modern inline six will make its debut on the upcoming generation of the E-Class, set to debut sometime in 2016.
This is a great bit of news considering that fans of the brand have condemned Mercedes for killing the traditional inline six-cylinder in the 1999, even though it was a better package than Mercedes-Benz's V6 engines from that day and age. Diesel fans may remember that the last oil burning straight six from Mercedes-Benz has succumbed back in 2005, when the OM 648 CDI was available on the W211 E-Class and W220 S-Class.
According to manufacturer insiders that dropped Motoring a few hints about what else is there to be expected, we've learned that the SL roadster could eventually get the rumored engine architecture, followed by a "much wider range of Mercedes-Benz models." Further more, no AMG variations of the six are under development.
If you think about it for a second, the only manufacturer currently production inline six mills is BMW, and it stuck to the recipe for good reasons. Compared to V6s, straight sixes are more refined in operation, a tad more frugal and the power delivery is slightly more linear than on V6 mills. It's not clear whether Mercedes-Benz intends to develop a diesel version of the upcoming turbo straight six.
All we know is that the petrol-powered family will be available in capacities ranging from 2.2 to 3.5-liters, with the entry-level 2.2-liter version expected to churn out 367 horsepower and 650 Nm (479 lb-ft) of torque. The range-topping 3.5L I6 will presumably replace the current 4.7-liter V8 as the most powerful non-AMG version of the 2016 Mercedes-Benz E-Class W213, and will deliver some 435 horsepower and 750 Nm (553 lb-ft) of torque.
The current Mercedes-Benz C-Class W205 will reportedly get the all-new twin-turbo straight six as well.
