Even now there are turbocharged gasoline engines making nearly as much toque per volume of engine displacement as diesel engines make. Gasoline has the potential for huge torque and way more power than diesel.
What’s missing is the fuel economy. Variable compression ratio goes some way to address that.
Another thing that is missing is emissions. Past particulate matter emission regulations have only been for diesels dropping it from 0.10 pre-2007 to .01 in after 2007. Gasoline engines were omitted from all PM requirements. Now many gasoline direct injected engines emit more PM than modern diesels and some even emit more than pre-DPF diesels. How long will that last?
Shiner,
Isn't there another diesel emission standard coming out relatively soon?
Not that I am aware of. Stage 1 for diesels was tighter emissions and stage 2 was for higher fuel economy which is why 3/4 ton and up trucks will soon have an mpg on their window sticker.
