Could you please tell us how we can find your website?


Just click the attached photo in the signature area of this post. The Engine, transmission, chassis, and other "detail" areas contain most of the specifics.

In the same way the M113 V8 surpassed the M119, the M273 V8 is more powerful, has better fuel economy, and produces lower emissions. The M273 based 550 produces 26% more HP and 15% more torque than the five liter M113 it replaces. Sticking with the theme of looking at numbers over a range, my M113 based 430 produces 295 lb-ft of torque between 3000 and 4400 RPM. This new M273 based 550 has over 290 lb-ft of torque available at 1000 RPM.

The “best” engine design is a moving target. Fortunately, the engineers at Mercedes Benz are chasing that target.
Awesome. Thanks.
