That would be too obvious

Well, what is the market for the CR-Z? It looks like an oversized two-seater that gets mediocre mileage for a hybrid, a far cry from a new Insight.

Looking solely at price and performance, the CR-Z is not bad. It's about $5K cheaper than the Prius, and can still get over 50 mpg, possibly closer to 60 on the highway, if you believe the people on the CR-Z forums.

Hopefully the final drive ratio is as good as the CVT or else the addition of the 6th gear will be not reaching its potential. Even in the 10th gen Corolla the auto had a better final drive ratio than the 5 sp to help fuel economy.
Valvematic basically is a secondary rocker that adjusts the height at which the cam lobe "engages". My guess is that it makes less peak torque because they can't use as much lift as the old engine in the midrange or else the cam duration would be too high.

Who cares about the lost torque though, this is the first entry level car engine with an advanced valvetrain hitting the US market! Not a BMW, not a Nissan VQ37.

And the manual gearbox will probably have short ratios, but I'll take 6 short ratios over 5 anyday.

The linked Forbes article seems to be missing the one interesting thing about another bland Toyota: the belly pan.

This month, my Automotive Engineering International magazine had a nice image of it, with the panels highlighted purple.

It reported a Cd of 0.28 for the Corolla, due in part to these strategically placed under covers.

Maybe we could learn something here that would be simpler to fabricate but still get measureable improvements.

Weird...cuz the Cd for the outgoing Corolla was 0.28..

Some of the belly pans already exist on mine like the portions around the engine and transmission, wheel spats...I added the under radiator to chin panel already thanks to Ecomodder. Now to try out the mid and rear ones...

I have also lowered my car slightly below the new ones height.

Just goes to prove Ecomodder is one step ahead of the manufacturers on many fronts. I can nearly already the enjoy fuel economy gains claimed by the new model via Ecomodder tips and tricks.

That is fairly average coef actually. The '14 Mazda3 Sedan has a .255 coefficient.
