the solara's v6 i believe is a common swap motor into mr2's and the like. very powerful, especially with bolt-ons.
plus, he's comparing a mtx to an atx. a mtx mazda 6 with the same modifications has 25 more hp than an atx with the same mods. plus he had a passenger filming. plus the solara stock is rated 225, where the mazda is rated at (overrated) 220.
