Wouldn't it be easier...

That's how hybrids get their highway MPG increase anyways, with Atkinson cycle. Perhaps they'll figure out how to do this with Valvematic

I hope they just make the gearing on 6th really tall, which will help a lot with hwy economy.

But yeah look at those lexus hybrid engines and the output...toyota can easily make a efficient supra

Problem with that is the lack of fueling stations umm everywhere

Do you think Subaru would let toyota use their platform without wanting a piece of the pie?

I doubt this platform is going to be used in any other model being shared by toyota and subaru.

With a valve-throttled engine it might be possible that taller gear =/= better fuel economy, since with continuous valve lift/duration control you can have a compression ratio that is "lower" than the expansion ratio in effect, which would mean maximum efficiency would be reached at somewhere around the same rpm but at much lower torque. With conventional engines tall gearing would be the easiest way to get good cruising efficiency.

I like your explanation and details .


And @ Archer256, if you subscribe to the idea of the hydrogen car economy, you should look at the math for making it. Good luck digging through the crap(pardon me) that is all propaganda or misinformation.

lol thanks? personally I think hydrogen is going to be a bit difficult because of storage issues. CNG is great as a fuel too, except it has basically the same problem just not as bad, which is a huge shame since methane is insanely easy to find.

I remember corn doesn't yield very much ethanol and isn't cost effective, so I don't think that's an option for sustainable fuel, until more effective processes mature. There's probably hope in more ethanol fuel though.

Sorry dude, I was making a comment towards Archer256.

Edit: Fixed it now.

You are being really vague on your second paragraph. You might want to just delete the entire post, IMHO. I'd hate to be held responsible for turning this into an Hydrogen or Ethanol thread . If you please would, .

They could build say a 210hp turbo Yaris with a 1NZGTE, put better suspention, a LSD, ect. and BAM type R Si....It would probably be cheaper than a Si also, weigh lighter, and just generaly be awesome. With all of the R&D it would take maybe a year. We could be driving it TODAY! A 200hp Yaris, 300hp Corolla, and a 350hp camry looks better to a enthusiast than a single 200hp RWD sporrts coupe...

I don't want an old mans car with a hammer under the bonnet. I want a purpose built sports car. A vehicle with RWD and gorgeous design. A car that makes me smile whenever I see it in a parking lot. A car that makes a statement of who I am. A car I can take out on the track and have fun in.
A car that shows that I'm hungry for life and not a tired old bore.

I lol'd

but seriously, someone already mentioned it.

High volume vehicles like Camry, are designed with cost in mind, as opposed to performance. You cannot just bolt in a 300hp (230kW) Engine without thinking about impact to Chassis, body etc. Although most cars have similar chassis strength these days due to years of experience from manufacturers... still you have to understand long term durability implications.

High power engines tend to be less durable in the long term just due to the forces they under go. Not to mention drivers will most likely abuse them.


But also the Economic side of it, high performance engines have higher grade metal, extra reinforcements etc and if you manufacture them in the millions, they cost a lot from R&D side of things and 99% of the market doesnt even care for it..

A Yaris buyer 9.9/10 of times will not buy a Yaris due to power output, but rather to price/practicalility and economic values.
