The 2010 TSX feels pretty quick on the street, and a quick look at the dyno plot below explains why. The torque curve is as flat as we've come to expect from J-series V6s and it pulls hard right to the fuel cutoff (which appears to cut in at around 7200rpm). This car would be ferocious with a 6MT.
For those who are interested in seeing how the horsepower of the TSX compares against the Accord V6 6MT and 5AT, here's the plot. As you can see, the TSX V6 falls almost exactly in between the two Accords up until the final 1500 rpms of the rev range, where the power of the VCM-equipped Accord V6 sedan fades off.
