My E350 Prem. Plus coupe, I've always thought that the lbs ft, torque figure for my OM642 was 458lbs ft. Which is what reviews, and road Tests give. Just looked up my VIN No. it gives, Engine,increased performance. Torque 700 newton/mtrs, which in turn gives 516.22 lbs,ft. of torque. No complaints from me, always thought it was a bit quick compared to my previous E350 OM 642 coupe. I've had the car more than two years.
