I know in the past you could see Honda's motorcycle roots in their cars, where the engines were small in displacement, high revving, and highly strung. Low end torque? "What's that?" asked Honda

. I'd say their engines now make better torque numbers than in the past, but I wouldn't ever call Honda/Acura a class leader in the HP/Torque department. For a lot of their cars I've never really looked for dyno plots to compare with the manufacturer's ratings.
10+ years ago, there was no industry standard as to how to measure an engine's power and torque numbers. So manufacturers were all over the place with the numbers that they published. I think about 9 years ago, there was a new SAE standard that came out for measuring engine performance. Honda started following it and they published new peak HP/Torque numbers. As a result of using the new standard, I think most of their engines, while unchanged, had lower numbers than the prior year.
From my casual and informal interwebz 'research' and reading, here are my opinions. Honda/Acura's published engine performance numbers look pretty accurate, where the dyno plots (when accounting for drive line losses) seem to match the engine ratings. While I haven't seen their dyno charts, Hyundai/Kia seem to overrate their engines. This is more apparent in the times derived from instrumented track testing. I wouldn't be too surprised with this, as they overrated the EPA fuel economy ratings on some of their cars as well. The Germans, on the other hand, appear to underrate their engines. The HP at the wheels seem to be just a hair shy of what the engines are actually rated at. I haven't read enough about other manufacturers to see if they had any trends in regards to reporting engine performance. Again, please note that these are only my own personal opinions
