In addition to meeting the FRA standards for buff strength, the cars feature crash energy management (CEM) systems. One of these CEM features is crumple zones at the ends of each car. These areas are designed to deform and absorb forces in a collision. | In addition to meeting the FRA standards for buff strength, the cars feature crash energy management (CEM) systems.

Each car is powered by a 760 horsepower [[Cummins]] QSK19-R diesel engine located under the floor. The QSK19-R is designed to meet the EPA Tier 4 emissions levels.<ref>[http://cumminsengines.com/cummins-qsk19r-to-power-nippon-sharyo-dmu Cummins QSK19-R to Power Nippon Sharyo DMU Train Destined for New Transit Routes in North America].

After years of study and analysis, the Sonoma Marin Area | After years of study and analysis, the Sonoma Marin Area Rail Transit (SMART) concluded that FRA-compliant DMUs would be best suited for the service. The SMART Board issued a request for proposals in April 2010. Proposals were received from CAF, Sumitomo Corporation of America (Nippon Sharyo), Siemens, Stadler, and US Rail Car. Firms were allowed to submit non-FRA compliant proposals. Siemens had submitted a an FRA-compliant design along with the non-compliant [[Siemens Desiro|Desiro]] design. Stadler had only submitted the non-compliant [[Stadler Rail GTW|GTW]] design. | ||
Sumitomo's proposal had scored best and it was recommended that the SMART Board award them the contract. The SMART Board placed a base order for 18 (later reduced to 14) DMUs in December 2010. The contract includes options for 146 more units.<ref>[http://www.nipponsharyousa.com/tp101216.htm Nippon Sharyo and Sumitomo Corporation Receive Contract for new North American standard Diesel Multiple Unit Cars from SMART].
