Replying to: kdhspyder (Sep 25, 2008 3:52 pm) 2009 Corolla, 2745# + 300# test weight = 3045# likewise, 2008 Civic, 2630+300=2930# 2009 TDI, 3230+300=3530# 2009 Prius 2932+300 = 3232# 2009 Corolla, TFC/IW = 1/(39*3045)= 0.842e-5 gal/mi/pound 2008 Civic, TFC/IW = 1/(38*2930)= 0.898e-5 gal/mi/pound 2009 TDI, TFC/IW = 1/(43*3530)= 0.659e-5 gal/mi/pound 2009 Prius TFC/IW = 1/(44*3232)= 0.703e-5 gal/mi/pound Smaller number is better. TDI and Prius are really the same efficiency since there is 10% more energy in diesel fuel. Factor that out, they're the same. The gassers need 20-28% (call it 25%) more fuel energy to do the same amount of work as the diesel and the hybrid. Inefficient. Hey, I have a furnace with 92% heat-to-energy efficiency, and compact flourescent bulbs that are four times as efficient at converting energy to light as incandescent, why should I not also be concerned with the work-to-energy efficiency of my vehicle? 25% is a big difference. Civic and Corolla are out of consideration.

Replying to: 104wb (Sep 25, 2008 5:45 pm) Looks like the hot ticket is to drive a fully-loaded class 8 truck (80,000 lbs) that gets 7 mpg. That'd be roughly 3.7 times better than the TDI. Next stop -- freight trains.

Replying to: ruking1 (Sep 25, 2008 3:59 pm) At that time I looked only at the hatchbacks. Under similar circumstances today only the Prius and the SportWagon would be under consideration. However being basically cheap in regards to transportation if I was in the market today I'd look first to find a good USED hatchback like a $14000 - $15000 Prius for the best combo of utility and fuel economy. |

Check the date of this article. Not to mention the speeds and mileage achieved. Over four years ago and( I still can't buy this car!!!) Honda Diesel Sets New World Records Date: May 07, 2004 18:07 Submitted by: Jeff Source: Honda UK PR Credibility Rating: N/A Honda’s new Accord 2.2 i-CTDi Sport has this week set no fewer than 19 world speed records and achieved 3.07 litres / 100 km (92 imperial mpg, ~76.6 US mpg) fuel economy to boot. British racing driver Robin Liddell and freelance journalist Iain Robertson were part of the European record-setting team. Amongst the speed records set, which were all achieved in Production Car Class B (2000 – 2500 cc), were 133.04 mph (1 mile flying start), 84.25 mph (1 mile standing start) and an average speed of 130.38 mph over a 24-hour endurance period. These records were all set at Papenburg high-speed oval test track in north-west Germany on 1 and 2 May, and are all subject to FIA ratification. Two production cars, randomly selected by FIA officials, were used to undertake the speed records, and apart from the fitting of roll-cages, racing harnesses and radio equipment for track-to-pits communication, no other modifications were made to the cars. Following the speed record attempts, the same two cars were then driven 419 miles from Papenburg test track to Wiesbaden, near Frankfurt in order to complete the fuel economy run. The route comprised of a mixture of motorway and non-motorway driving, during which one of the Accords achieved a staggering 92 imperial mpg (US mpg=~76.6) average. GO FIGURE!!

Replying to: larsb (Sep 25, 2008 2:25 pm)  I really think you are spot on in this assessment. Toyota will be STILL be behind; as they were when they came out with the T100. Cummins is doing a plant upgrade (I posted I think a long while back) as they are coming out witha 150/1500 series V8 diesel engine !! 300 to 350 hp and something like 475-575 # ft of torque!? Woo HOO for those that want/ need this platform/product ! It would also be a hoot if they could get this pp into a larger sedan type vehicle. It could be a top notched platform, especially if it could pull down 35 mpg and/or better !

Replying to: kdhspyder (Sep 26, 2008 10:34 am) on multiple types of alternative fuels. I could name 20 different feedstocks and more. If I leave out coal oil, "we don't have much of that, do we!" All the rest are renewable. With a near zero CO2 footprint. What you exhaust to the air is mostly absorbed by the plants that you get your next gallon of fuel from. Diesels ability to use alternative fuels is the single largest factor, why you can't buy a 2008 diesel accord!!! What am I going to do with all that dino oil. Follow the money!!! Nature's key to survival is diversity. Conservation and diversity is our key!!!

Replying to: dworthen (Sep 26, 2008 1:20 pm) I think you are just about spot on. Otherwise why did the price of diesel start going up right in line with VW, MB & BMW launching 50 state diesels? Alternative biodiesel fuel will become feasible and practical. The argument is they have not done that to ethanol. Well they sure did in the 1980s with sugar ethanol that is a threat to fossil fuel. Not to corn ethanol. That is a BIG money maker for the oil companies. It takes at least as much fossil energy to grow and distill corn ethanol as you get BTUs in return. Honda may still be trying to get 50 state approval. I thought they had it a year ago.

Replying to: cdnpinhead (Sep 26, 2008 4:49 am) Is there any way that I can take that as a compliment? "Looks like the hot ticket is to drive a fully-loaded class 8 truck (80,000 lbs) that gets 7 mpg." It is the hot ticket if you want to move 60,000 pounds. It's none of my business how much work you want to do with your vehicle. That's for the government to dictate, apparently, by regulating fuel economy instead of fuel efficiency. A class 8 diesel is an efficient way of doing it though. You won't find any class 8s with spark ignition engines. "Next stop -- freight trains." Correct. Hybrid-diesel technology, and the most fuel efficient form of transportation on Earth. Won't find any SI engines there, either. |
