Actually at this point of time Toyota engines have surpassed Honda's, and not so much because Toyota has better engineers, but because Honda failed to make any progress in the last 6-7 years and it's beginning to catch up with them. The new RL and TL are only at the beginning of their cycle, but once the new ES comes out its gonna beat both of them in the performance department, and luxury wise the ES was always ahead.

I predict very slow acura sales in the future unless the TSX gets the turbo 2.3 engine, TL gets upped to current RL engine tuned to 300 sae HP, and the RL gets an optional 4.5 v8 pushing close to 400 hp. And SH-AWD should be made optional across the entire line-up.
