If they desire to succeed, car companies typically design and name cars to appeal to the market they intend to penetrate. A car called "Mahindra" is unlikely to be a good fit for any US market. Marketing strategy may not be the typical focus for this site, but let's be honest: the finest hybrid vehicles will not sell if they are not marketed correctly. You could come out with a 1000 mpg diesel hybrid, but if you give it a tard name like "Birdy Num Num" and nobody will buy it, the environment will never benefit.
