Five Diesels from Europe that will out-eco a Prius

-AutoBlog

Your Prius may be rated at 60 mpg in the city and 51 mpg while cruising the countryside, but chances are youre not realizing those numbers the EPA obtained by strapping Toyotas Hybrid Synergy Drive to a dynamometer. In Europe, where fuel economy is calculated by actually operating an engine on the road while its under the hood of a vehicle, the Prius returns a more realistic 47 mpg in the city and 56 mpg on the highway, or 5.0L/100km city and 4.2L/100km highway in the continents native metric.

This more realistic fuel economy rating lowers the bar enough for a handful of European small cars to beat the Prius in a game at which many Americans believe its indomitable. And guess what, these cars from the old world all use highly fuel-efficient diesel engines.

If many in this country are so concerned about eking the most amount of miles from a gallon of fuel, why hasnt the modern diesel enjoyed the same success here as the hybrid? The easy answer would be the ghost of diesels past, particularly a bad batch of oil burners designed by Oldsmobile in the 1980s.

The more complicated response is that Ultra Low Sulfur Diesel fuel hasnt been readily available in the U.S. like it is in Europe. This special blend of diesel contains less sulfur, which reduces emissions, but also allows for better emissions control systems to be used on a diesel engine. Fortunately ULSD will be the new standard in the U.S. come this fall. Some companies, like DaimlerChrysler, are waiting in the wings with 50-state approved diesels that are powerful, clean and get grand gas mileage. Will diesels finally become the eco-peer of hybrids? Who will be the first to marry the two in an ultra-efficient diesel hybrid production car? Time will tell, but we can all breathe easier knowing more green options are sprouting up every year.

80 mpg!!! I would buy that Audi for a daily driver in a heartbeat. Then I'd set up a bio diesel plant in my garage, lol
 
I can't tell you how many of my Vw Tdi jetta and golf customers that get around 45-55mpg.
 
This is just more proof the EPA really needs to work on their recordings. They have never been right. Not even close.

And even the VW Polo diesel over there gets more mileage. For years these cars have been successfully stomping on Prius' numbers. Hell even the Honda CRX HF was getting over 50 UMPG (US Miles Per Gallon, not UK) in naturally asperated, gasoline form in the 80's.

Diesel also holds more power per gallon than gas and theoretically cheaper to produce. Why more companies don't use it is beyond me.
 
Someday...

Useful cars, to bad you can't get them here. The Prius is top dog at the moment because of percieved reliability, moderate cost, and you can fill up anywhere. Most Americans remember diesels as loud, chugging, slow things belching clouds of black soot. We've really never seen a modern one. Just a few VW's and they don't have very good reliablity, nor does Mercedes. I also can't fill up across the street. At the moment diesel costs more per gallon, and if I have to drive 20 minutes to find a fillup some of the fuel savings is washed away; I have to make a special trip, so it's not as practical. I'll wait to see the new diesel that Subaru comes out with. Or Mazda, Toy, or Honda- the only four car brands that ever make it on my shopping list.

I beg to differ. The last Mercedes diesels that were over in the states did a great job and they were a magnitude more reliable than their gas counterparts.

Also, the VW is just unreliable in general, not necessarily the powerplant. By design, the diesel engine is very reliable. The exhaust is cooler so the turbo has a longer life, the diesel also acts as a crude lubricant so it's better than nothing, and there are less moving parts. I would suspect another issue with diesels is the assumed poor performance in the cold. This has been mitigated of course, but still perceived bad.

And the reason diesel costs more is because the trunking companies will pay it. Diesel is cheaper to make and should be cheaper than gas.
 
Only problem with the Vw Tdi's is the glow plugs go bad ever so often. The owners don't have their timing belts replaced in the correct interval, and they have a plastic bladed waterpump.
 
I doubt it's cheaper to make, there is an extra process or two to get gas oil out of crude. Gasoline can be distilled straight out I believe. And trucks and trains have no choice but to pay higher prices, until somebody makes a Legacy Wagon diesel that can haul a 40,000 pound roll of steel. When I was growing up (30 years ago) diesel was always a fair amount cheaper per gallon. I don't know why it's reversed now. Possibly a higher percentage of production capacity is for the other products made from crude so leaves less for diesel? Maybe it's taxed more, or the gov't does less to keep it's costs down. But if somebody brings out a reliable diesel car I'd consider it.

I'll take the Citroen.

Diesel is more now because of the increased demand...The more Diesel we use the more it is going to cost us in the short term. Demand is fairly constant in Europe so the prices remain stable (and getting higher) because of the new processes that are necessary to get the low-sulfur diesel to market this year.

I think that if America starts to use more Diesel then some of our production should start to switch over from unleaded and prices should go down somewhat.
 
I cant wait when I move to Portugal this summer to drive my little 1.5 turbodiesel car that get about 50mpg :D

Well the temperature at which diesel is refined at is lower than gasoline, so it's cheaper because the refineries don't have to support the higher temperature. Laws about emissions and taxes make diesel higher than gas now. There are higher taxes per gallon of diesel than gas.
 
Diesel good!

Cool, I'm all for more diesel options here in the US, now that the engines are much more advanced. Hopefully policy changes will increase the rate of adoption.

Now if we can just weed out more of those hunkering SUV's on the road to increase my safety in my tiny little economy diesel.
