Why Diesels Are Greener Than We Think This paper is not intended to condemn hybrid engines, as they can be good engines and a practical means for vehicle manufactures to power their products or meet emissions. This is to present the idea that gasoline hybrid engines are inferior to Diesel engines. I concede that a Diesel hybrid engine would be more beneficial in some applications. Ideally, we need to come up with better road systems and better road surfaces. If the roads are better maintained, we could use harder material tires without sacrificing comfort and thus gaining in fuel economy due to decreased rolling resistance. If the roads were maintained as well as railroads, then we could really get the economy of a locomotive in…show more content…
Even the “Greener” gasoline hybrid Toyota Prius can only manage 53 miles per gallon. If you are only running on gasoline, the best you can get in a vehicle is 42 miles per gallon. Yet even with the hybrid technology available today, the consumer only sees a marginal return on the upfront higher cost. The cost to replace a hybrid battery pack runs up to $7,000. This adds up to approximately zero cost savings over the life of the vehicle. This is why incentives from the government are offered and why hybrid cars and trucks only appeal to some people’s conscience and not their wallets. For example, Volkswagen’s Diesel models all range from 40-46 miles per gallon. I do not call into question that a hybrid vehicle is more fuel efficient than a non-hybrid vehicle because that is nonsense, but I do think diesel engines are superior to gasoline hybrids in fuel economy and usefulness. I intend to prove the value and affordability of the Diesel engine versus the gasoline hybrid engine. Many years ago we succumbed to the idea that Diesels are polluting, dirty, and noisy. This may have been true back then, but we are now in a new era of Diesel engine performance. Advancement in Diesel engine technology was mandated by stricter new emission standards by the Environmental Protection Agency (EPA). The EPA requires that newer Diesel engines have TIER 3 compatibility. This meets and exceeds EPA 2010 model year certification. After the 2015 model year
