LOL that was good. I guess it makes the difference of those 2 liters driving over 500 miles doesn't it.

prius is the first hybrid car and needs a lot of work to make a good result but its the start of a new era!
I believe that if we make a car with only electric motor+good reliable batteries and charge them from a electric power plant the efficiency is much better!
The only problem is that the (Li-ion) batteries are heavy and there is a safety issue with some explosions from overheat...

deisel is a 10% more energy dense fuel. So the prius actually used less energy. It also cost more per litre. Not a clever test

That PROVES NOTHING!! Im Sure the BMW HAS A LARGER GAS TANK!!! IT CAN HOLD LOTS OF GAS COMPARED TO A PRIUS!! PLUS ITS COSTS AN ARM AND A LEG TO FILL UP!!!

Diesel is more expensive but it burns much slower so its a bit cheaper in the long run. Either way you have to admire the BMWs engine.

The BMW is ungodly pricy compared to the prius... It also uses more expensive fuel.
Plus the fat guy was in the prius.

Exactly. Be scientific.
49 diesel vs 41 petrol. Petrol burn energy 35MJ, vs 41MJ for diesel.
BMW energy consumption: 49*41=2009 Megajoule
Prius energy consumption: 41*35=1435 Megajoule
As you see, even in a situation favouring the BMW the prius is far more energy efficient. If the test would take place in a city, the difference would be huge.

IF THE FAT GUY WEIGHED ABOUT 100 or MORE POUNDS LESS THE PRIUS WOULD HAVE DID BETTER!!!"With Fuel Economy" PLUS BMW HAS A LARGER GAS TANK!!
