I drove a Citroen 1.2L Diesel in Spain more like 15 years ago. At the time, one of my other cars had a Chevy 350 cu in (that's about 5.7L for you kids). At first, I though I might as well get out and walk. But once I figured out that I couldn't shift it like an American sports car, the Citroen and I came to a pleasant understanding: it was a wonderful, if small, car. Bell hops at the hotels would ask me where I was from, how I liked the car, and usually, what I drove at home in the US. I would tell them that my engine at home was 5 times as large, and some would wonder at my Spanish: once, a fellow said "Chevy?" and I smiled yes... it was fun.
I miss that car: it was well built, and I couldn't complain of the fuel economy. I wouldn't buy a hybrid: for one thing, I tend to tow a trailer once in a while, and my tastes run to an FJ Cruiser, but I'd certainly consider a large-enough vehicle with a Diesel powerplant.
I drive one of the Citroen babies (1.2L turbo-deisel) 5 years ago in Spain for several weeks over 4000Km; less than 4L/100km doing 120Km/hr. Experience: smooth, powerful, miserly like US automakers / customers don't have a clue.
We don't get out enough nor realize the joke we are. Thanks for your article and quiet significant observation.
ps: did you ever have to change one of those HEV batteries, do you know how often you have to in the car's life & related $, any idea of that environmental overall impact? Time to look at the numbers (all of them including 'electric vehicles').
I also converted/drove a Natural Gas conversion dual fuel minivan; a local after-market update shop on a Pontiac minivan. Technology easily applied ($2500) after mfg. and paid-for using a local sales-tax rebate, that is developed to production levels in Italy (over .5M NG vehicles in use). I can gas-up at home with a compressor appliance outside my garage. Engine life is extended with higher octane rating / cleaner burn. Gasoline is still there with a dash-mounted switch.
It's out there, just get to it. Good hunting .. & travelling.
I think HEVs will benefit once solar has dropped in cost to the point that consumers have excess power and need a place to put it.
I drive a Jetta TDI myself, powered by B100 biodiesel produced from recycled fryer oil.
Nice profile of the potential of diesel. And, fortunately, given that as the author states, his company wins with wide-spread adoption of either diesel or HEV, I'm betting this is more balanced than so much of what we read on the subject these days.
I think it is important to have a lot of research going into HEV and pure electrics, and we need early-adopter purchases, but in the near-term, the planet could probably get the best reduction in fuels use and pollutants per buck by looking to solutions like modern diesel and super efficient gas power plants. I wonder how much fuel we could save simply by reducing the horsepower in all vehicles by ten or twenty percent.
That's probably the real hold-up. We want power and lots of it. To satisfy that desire, we have big gas engines and hybrids that are more about increasing horsepower than fuel economy.
