Diesel engines in passenger cars are making a US comeback, with companies like Honda and VW developing new diesels that meet stringent clean air standards. GM has decided to get in the diesel act as well, and blogger Bob waited until the last minute to discuss diesel plans on his video blog on Fastlane. Before spilling the beans on the General's future oil-burning motors, Mr. Lutz first listed several reasons why diesel engines are becoming increasingly less feasible due to tough Tier 5 Bin 2 emissions and escalating technology costs. He then explained how direct injection and Homogeneous Stratified Charge (compression ignition) would all but close the fuel efficiency gap between gas and diesel powerplants.
At the very end of the video blog, Mr. Lutz stated that GM was working on a diesel V6 for crossovers and passanger cars and a 4.5L V8 for SUVs and light trucks. We say bring on the fancy new emissions and fuel-saving technology, so the market can determine which technology was best. Check out blogger Bob's diesel lesson after the jump.
