They need some direct injection for the 6.2...

Direct Injection is available on the GM truck engines for 2014 and has actually been available in Ford trucks for years, as long as you bought a diesel. Port injection is so advanced today that DI is only a slight advantage. The potential dangers of extremely high fuel pressures added to the expense of the hardware and software required for DI have kept it out of most trucks prior to 2014. GM adopted DI to offset the inherent disadvantages associated with their OHV V-8 architecture compared to Ford's OHC design. With that said, DI is is probably inevitable due to more exact fuel tuning requirements necessary to meet the escalating EPA regulations on the horizon.
