If you read the whole plan, you'll see that the 5.7 is on the board until 2014. However it is being upgraded to multi-air. They're already at 390hp in the ram so I'd say 400 wouldn't be an issue. Getting these approved by the government won't be an issue IMHO because they are keeping the volume low while introducing higher volume a and b segment cars. The government has told them they need to get serious on the electric vehicle though.
