Although it looks quite similar to the IS 250 and IS 350 sedans on which it's based, save for a slightly more aggressive profile, the IS-F is an entirely different beast--race-ready for weekend jaunts on the track yet docile enough for daily driving. The IS-F's powertrain is a little smoother and better suited for everyday driving than that of the BMW M3. The IS-F's strong standard feature list makes it a very strong value.
