About Lexus GX460
Two steps forward and one step back seems to be the rally cry of the new 2010 Lexus GX460. This second-generation, three-row, mid-size, body-on-frame SUV from Lexus replaces the GX470, which, as its name implies, had a slightly larger engine. That 4.7-liter V8 engine, however, couldn’t touch the combination of power and efficiency found in this new 4.6-liter V8. The new engine manages to pump out 301 hp and 329 lb.ft. of torque while returning 13 percent better fuel economy, now ringing in at 15/20 mpg. It also uses a second-generation frame and an all-new body with some class-leading features. (Source Autoblog)
