The 2010 Acura TSX is once again at the head of its class when it comes to engine performance. The 2010 Acura TSX has just one trim, but has two engine options. The first option which comes standard in the TSX is a 2.4 liter four cylinder engine which produces 201 horsepower. Acura's i-VTEC technology increases the torque and horsepower in the four cylinder engine. The four cylinder engine gets very good fuel economy with 20 miles per gallon in the city and 28 miles per gallon on the highway when coupled with the 6 speed manual transmission. When the car is upgraded to the automatic transmission, fuel efficiency improves to 21 mpg in the city and 30 on the highway.

For those people looking for more push out of their TSX, a V6 engine is available. The TSX V6 engine is a 3.5 liter VTEC engine which produces 280 horsepower. The V6 engine also produces 254 pound feet of torque. Considering the power of the 2010 Acura TSX V6, it gets surprisingly good fuel efficiency. In the city, the TSX V6 gets 18 miles per gallon. On the highway it gets 27 miles per gallon. Unlike the four cylinder engine option, the TSX V6 is only available with the five speed automatic transmission.

The four cylinder engine in the 2010 Acura TSX is very similar to the 2009 model. The 201 horsepower engine is slightly less powerful than the 2008 Acura TSX engine, which produced 205 horsepower. Before 2010, Acura TSX purchasers did not have the option of a V6 engine. The 2010 Acura TSX is once again at the head of its class when it comes to engine performance.
