Chevy will lose more than half of its currently available passenger car models, including the full-size Impala sedan, the mid-size Cruze and the compact Sonic. Plus the functionally viable Volt electric car, which gets the noose for probably just that reason (separate rant; see here for more about that).

Ford has already shed its entire Mercury division and GM its Oldsmobile, Pontiac and Saturn divisions.

More will inevitably follow.

Because how many different ways can GM re-sell the same relative handful of closely related crossovers and trucks? And how long will GM (or anyone else) be able to sell trucks and SUVs at all, given the anvil descending of a mandatory minimum 50 MPG federal fatwa?
