Hemis are the most efficient combustion chamber design, so that is why they are used by just about all engine makers today.
And you get the BIG gold star!

I'm not trying to be rude, but you are dead wrong. Sorry...

Here you go, where are the "5" sides?

Too bad the Yaris and just about every other 4 valve setup doesn't look like that diagram. Take a LONG HARD look at the chamber I posted. You will notice it is "round". But nice try...

The combustion chamber on a penthead combustion chamber is bowl shaped, just like the other Hemi. The sparkplug is in the middle most of the times just like the pictures. Dodge is just advertising old worn out technology by NOT using the Penthead Hemi. I think I will make a bumpersticker and it'll say " Yea, It's got a Penthead Hemi."

I don't have mine yet so I have not had this experience. However, I do think it's because of it's interesting look. I LOVE how the car looks...don't get me wrong, but not everyone does. My X thinks it's ugly.....but he drives a broken down POS.

I had a first today.

I was following a Volvo S70 and the guy pulled over to let me pass. He followed me to my destination and peppered me with questions about my car. He loved it.

I probably should have told him that it was modified. I can see him at the dealership insisting that you can get a Yaris with HIDs and a sunroof.

i was sitting at a stoplight a couple of weeks ago and a couple of guys sitting in a old pickup truck next to me rolled down the window and said, "nice car!". i nodded and gave them a thumbs up.

We had a little snow this week - about 2 inches. As usual, local pickup drivres were having a hard time cos they cannot remember from one year to the next that lead-footing it doesn't work in the slippies. At the top of one hill, having quietly idled up it in 3rd, followed by a Jeep, he rolled down his window and shouted "That's the smallest 4x4 I've EVER seen!".
I told him he still hadn't seen one this small, and drove off.
Happy Days!

Stares.... I get questions Stares and more stares... I rebadged the car with the Netz emblem on front and the Vitz wording in the back and also have a different licence plate and people are going nuts... What kind of car is it? Is it a china car? Is it Imported? Hey look that car has a Chinese licence plate on it.... Thats when I have to speak up and say No it's a Japnese plate and the car is a Toyota!

Mine is the white one....


Sorry bad picture... it's from my cell phone.
