Get used to the concept of small bore engines with sophisticated turbo designs.
It's how car makers meet new emission standards and MPG requirements. The turbos kick in on acceleration, then shut off during steady cruising speed.
Those big thirsty 5L V8s are a dying breed. For that reason 550 owners should take good care of their cars and hang on to them. In 5 years they will be a rarity and possibly sought after.
