Honda to introduce a new 3.5 liter V6 diesel by 2010

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 Nikkei newspaper.

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 engine.

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.

Ethanol is a bust because it requires government subsidies to make it economically viable, it requires more energy to produce than non-renewable sources, and it produces less energy = lower mileage at the same "pump" cost.

I don't see how biodiesel has really solved any problems, either. Similar issues there.

And these fuels have higher emissions when you burn them, if you are about things like that.

The lower fuel efficiency is more than made up for by renewable resources. We are talking a few MPG's here, a few percentage points dude.

Ethanol contains approximately 30% less energy by volume. This can partly be made up for by the fact that ethanol allows higher compression ratios, but you're still looking at about 20% fewer miles to your gallon.

Ohh, and ethanol from corn is NOT a renewable resource, it requires vast quantities of natural gas to produce and electricity (75% of which is from fossil fuels in the US) to distill the corn to ethanol.

As I have stated below there are many other sources of biodiesel and E85 that do not require the use of natural gas. They are all renewable and some like algae actually eat other harmful materials during the process.

Secondly where I come from ethanol is much cheaper than gas so I would be more than happy to give up 20% efficiency and end up paying the same amount anyway if I cut my overall oil usage by 85%.

I do hold out some hope for ethanol from other feedstocks and especially for biodiesel. In particular the biodiesel from algae you mentioned holds tremendous promise, though it's still many years away from anything resembling widespread use.

Unfortunately though the reality of today (in North America at least) is that biofuels = ethanol from corn + $BIG$ government subsidies. While you say the ethanol is cheaper than gas, that isn't entirely accurate. You just happen to be paying for that ethanol partly through you income taxes instead of at the pump.
