Is there a reason why you're valuing performance at zero? 7.6 seconds 0-60 for that Camray, 8.0 for the Corolla. Surely some fraction of consumers care about that.
[0]Sadly.
That advantage mostly fell to hybrids and full electrics, because now you can make a fast car that satisfies the rules, but by that point the ship had already sailed and now people don't feel safe in a sporty little thing next to the neighbor's hausfrauenpanzer so now people want it to be fast and big.
If I'm sitting in traffic 45 min, one way, on my way to work around DC or LA, what's a wicked good 0-60 going to get me?
