That's not quite right. Using a Hohmann transfer orbit [1], you get from Earth to Mars in about 9 months. Using an Aldrin Mars cycler [2], you can get in as little as 75 days. Of course, the Aldrin Mars cycler requires more delta-v, but that's the point, if you have more delta-v you get there sooner.
