That's the tradeoff. I smoke you through the turns, and you get better gas mileage. I don't drive hard on commutes, but I don't work on the weekends =) Also,

That's the tradeoff. I smoke you through the turns, and you get better gas mileage. I don't drive hard on commutes, but I don't work on the weekends =) Also, the MS6 is a mid-size sedan, the TSX is a compact entry-level sedan that weighs ~400 lbs less. The Acura TL vs. MS6 would be a better comparison. Finally, gas mileage is much more related to the weight of the car mated to the engine, rather than the horsepower output of the engine itself. A simple example -- when people drop in an LS1 engine (when tuned it's upwards of 400hp+) to a Mazda RX-7 body - which weighs about 2400lbs - they get around 25-30mpg.
