This doesn't make sense. You are saying the engine wasn't built strong enough to handle the loads it is likely to see on a regular basis (which is probably true coming from VW). Accelerating at peak torque is most efficient. Shifting earlier would be less efficient.

For anyone wondering what is the most efficient way to accelerate, just find the peak torque and try to keep the engine RPM in that range during acceleration. Once up to cruising speed, bring the RPM way down.
