Do Ford still do research in North America?
I thought they bought all their technology from Bosch and Siemens.
NA DI is more a performance adder, Ford achieve similar torque with the 3.7 V6 as GM DI 3.6 but
the GM V6 produces more top end power. I bet that High Pressure pump and injectors are expensive.
DI is advantageous when linked to turbo charging the pair go hand in glove, everyone accepts that.
while GM is floundering around with naturally aspirated DI, Ford's Ecoboost is killing them with torque.
