Lol. Funny thing is the Toyota Aurion for example has more local content than the tru U.S / Korean Commodorethe only decent car that was there was the bloody tru blu aussie ve commodore.

Apparently my friend played the Toyota F1 sim. He said he got top time in it. I'm not surprised as his a pretty quick Simracer and has a Bike (CBR600 i think with metals used in aero construction - super light+strong) that he races/does laps around Oran frequently.lengy said:Went yesterday. The ladies at the Mitsubishi stand were definately the hottest, especially the tall long haired brunette. I got like 1 minute 3 seconds on the GT4 Evo Rally game beating the challenging car. I'm so awesome I got acknowledged from the guy operating the game. Loved the Toyota Aurion Sports Concept, but didn't get to play the Toyota F1 game. Sat in a few sports cars and of course the Aurion which I really wanted. Best car of the day would have to be the Audi R8. The Citroen C4 is a car I want but I'll settle for the Toyota Yaris YRX sedan.
There are advantages in pushrods. More compact design, no ohc so lower center of gravity, costs less, pushrods tends to deliver more low-down torque. I think the honda jazz even has pushrods. Look at ford's boss V8. It is an ohc design, but has a crappily undersquare bore/stroke ratio, and can't rev high enough to take advantage of it's better breathing capabilities. Plus the ohc makes the V8 sit up high, giving the car crappy cornering balance. I think you'll find the power gains from an ohc head on the Chev V8s would not be as great as you'd imagine, and wouldn't justify the increased cost/complexity/size.Schoolies_2004 said:^
Yeah cant believe HSV's have pushrods still..... companies like Toyota have had DOHC's for 15+ years!! If they went for a more technologically advanced engine they would be able to get ALOT more out of these massive V8's.
As for Aussie design etc, well the Commodore is the only one virtually, but Im prity sure alot of cars have Aussie design etc, for eg Australia had some input into the Aurion and have had a large say in the TRD Aurion (Which is only going to be sold in Aus once it comes out)
I dont take on the whole centre of gravity or cornering thing, overhead cams dont weigh that much in the scheme of things, the bulk of the weight is in the engine block itself... and this is just forgetting that most of the cars in the world with the best handling have overhead cams... just forget crappy Ford. The advantages of overhead cams in comparison to pushrod are well documented, namely way better fuel efficiency and more power, and you dont have to look far either.... personally I can compare my old arse 1993 V6 Camry which had DOHC and put out 140kw out of a 3L V6 against cars like the Holden Commodore with way bigger engines which until relatively recently only put out 150kw out of a bigger engine with pushrods.... or you can look at modern examples like the new Toyota Aurion with DOHC and dual VVti which out of a 3.5L engine put out 204kw while I dont know about the new SS but the previous ones with pushrod only put out 220kw with a MASSIVE 5.7L V8 engine. This is prity conclusive, 2.2L extra, which is SHYTELOADS, in something like the SS yet only 16 more kw... thats disgraceful... and Holden claim it does the 100 in 6.5, I think this is wishful, the Aurion does it in 6.5 with 300kg less weight - you'd need more than 16kw to make the difference! Having less valves, poor valve timing at high rpm, and the ability to use things like VVT being made virtually impossible are the major floors of pushrods.... and its the reasons why the top manufacturers stopped using them back in the early 90's.There are advantages in pushrods.

This is about the only thing I agree on... they do have a place in engines with large disaplacements... because these are the only engines you can get any power out of pushrod, and even then you are losing out big time compared to overhead cams.So pushrods have a place, especially in large capacity engines. At the end of the day, we should judge engines by how they peform, not because of how they are constructed.
i agree with you, except on the last line, cos the Aurion is alot better .Zozo6969 said:went motor show on sunday. cannot believe the amount of crap cars that are going around in australia at the moment. deadset, two thirds of the manufacturers had shit boring cars. saab, suzuki, citroen (shitroen), hyundai, volvo, ssang yong, kia, and even the big guns like toyota, honda, ford had some piss weak cars out there. and for those fricken manufacturers behind the bloody ropes, eg bentley, maser, ferrari, lotus, beemer, you had the shittest stands of all. the only decent car that was there was the bloody tru blu aussie ve commodore.
