Why not bring back an old reliable slant 6 cyl. from the past and modernize it some but not too much. Modern vehicles with so many electronic sensors and over dependence on computer modules. Design a simple, reliable, affordable but attractive daily rider for working class people. Now is the opportune time for it with all the way overpriced modern junk they’re peddling.
All that electronics is to meet the Fleet Fuel Economy Averages and the Clean Air Act pollution regulations.
SO even if they were to redevelop the venerable Slant Six, the engine would be unrecognizable..............
