For whatever reason, diesel engines get a bad rap in America. Even at their worst, they were never that bad (at least in my opinion). Torque, good gas mileage, and never a line at the gas station (just 5% of American cars are diesels). Plus, they last forever. Even so, the tide of public opinion still seems against diesel engines, and the major manufacturers are noticing.
Honda is ditching its R&D into clean diesel engines to focus instead on hybrids. As we all know, hybrids are all the rage right now, and Honda is hedging its bets by focusing on building band-aid cars instead of coming up with genuine solutions. Didn't try already try that?
