Why the /6
The May 2014 Automobile magazine has an article comparing the latest BMW sporty M3 sedan with earlier ones. They rave about the new 2015 "F80", a 3.0 L twin-turbo straight six which outperforms the clunkier 4.0 L V-8 and gets much better mileage. BMW drivers have always loved the straight six and the turbo makes it fabulous. We don't have to pay $63,000 to own one, just upgrade a neglected Mopar slant. For those metric-challenged, our 225 engines are 3.7 L and a 273 is 4.5 L, so who needs more displacement?
