A 5 series Beemer with a 2 liter diesel ? How common is that here ? Tested in 2008.
I know that things are different in Europe because of the high cost of fuel. But what works in Europe won't necessarily fly in North America. Not sure that BMW would sell many 2 liter 5 series cars here.
I love diesels. I have had several and have one now. My first one was a 1982 Rabbit and I could legitimately get 60 mpg at 60 mph all day long.
But . .
I do think the current hybrids are terrific though. My daughter has a Prius. She called me the other day as she was cruising down the highway on her way to work. Said she was getting 54 mpg at that particular moment. She says she averages about 50 mpg overall (somewhat lower in winter). That's pretty hard to beat.
