I saw this a while ago on TV, where they show the 2004 Formula Mazda(to replace the current Star-Mazda car which is old and shitty) and they stated that RX8 uses the same engine(which is true) and at the end of the ad they say Mazda RX8, with the engine of a race car. I find that statement quite funny, as clearly a) it is the otherway around, and b) why not more manufacturer use this? Dodge can say the Barber Dodge series uses their 3.5 liter pushrod V6 and that Intrepid/300M...etc uses the engine of a race car, or Ford can say Focus uses the Zetec 4 banger from the current Formula Ford car(which has a 20 years old chassis btw...the engine kept changing on those, all Ford, obviously). Or if Corolla still uses the 4AG, they can say they are using the engine of a Atlantic car......

I am sure some idiot online will pick this up...

It would be logical marketing for some, but the Focus f.e. stands too far away from the Formula Ford, and the brand has to have some sportiveness in its brand description to use such a fact in its commercials...
