While many domestic and foreign automakers are looking to hybrid technology to
improve fuel efficiency across their auto lines, Honda is looking towards
the tried and true: diesel engines.
It was reported last month that the next generation Honda
Accord would forgo its slow-selling and poor-performing Accord Hybrid with a
diesel variant. The oil-burning Honda Accord will feature a 2.2 liter i-CTDi Tier
2 Bin 5 diesel engine along with an ammonia-filled catalytic converter to
reduce NOx emissions.
Honda is also poised to make a new 3.5 liter V6 diesel
engine available for its larger vehicles including the Odyssey minivan, Pilot
mid-sized SUV and the Ridgeline mid-sized pickup truck. The new Tier 2 Bin 5
diesel will first be available in 2010 according to the Japanese
The engine is said to be 30 percent more fuel efficient than
Honda's current 3.5 liter V6 gasoline engine (rated at 17/24, 15/20 and 15/20 respectively
in the Odyssey, Pilot and Ridgeline based on 2008 EPA estimates). The new motor
is also said to produce 20 percent less carbon dioxide as the 3.5 liter V6 gasoline
Honda's new diesels likely won't come under as much
scrutiny for failure to achieve EPA estimates as has been the case with
hybrids. Honda knows this first-hand as it recently became the target of a class-action lawsuit
regarding poor fuel economy on the Civic Hybrid.
