GM

GM says this:

19 of our 2009 models have an EPA estimated 30 MPG highway or better2 — more than Toyota, more than Honda.

For 2009, we offer more hybrid choices than any other manufacturer. We currently have six hybrids available.

Well...yeah. Toyota and Honda made a few really good models. GM makes a million so-so models. Some of them are reasonably fuel-efficient. ('11 of our last 13 new-product introductions have been fuel-efficient cars or crossovers.' -- Okay, a bunch of them. Now stop wasting time and money on all those older models that get 6-20MPG.)

37 of our 2009 models have five-star frontal crash safety ratings.

So you have at least 37 2009 models. 19/37 = 0.513513514. But you clearly have more than 37 models or you'd say 'All of our 2009 models'. So probably far fewer than half, in the end.

From a consumer point of view, choice might be good. From a forced-new-owner of the company, it's not so good.
