FROM MOTOR TREND.

"The current 2.4-liter four will continue to soldier on, though Honda reportedly will give mill a good massaging to the tune of an additional 20-30 horsepower, up from the present car's 205 horses. A six-speed manual and five-speed auto will likely remain as the two gearbox choices. A spicier Type S variant -- powered by a 260 horsepower version of the RDX crossover's 2.3-liter turbo four -- is expected as well. There's also an outside chance that the TSX will receive the Honda's new clean diesel engine at some point."

I'll take a Type S for a DD if it looks good
