Are we going to have the MHD in the US?

Is there anyone out there that knows when we will get the MHD in the USA or at least the ability to add it to our cars.
I want the MHD feature on my smart.

GM screwed up the electric car, tried to 'convert' gas engines to diesel, bombed with the caddys 4-6-8 engine. Look where they are now. Yeeeessshhh

Any diesel smart would be a winner in my book. I spoke with an owner in Canada who averages between 65 and 70 mpg. Plus, I believe that most of the diesel technology today makes them not only more efficient but also cleaner than most gas engines. If GM hadn't ruined the US consumer's perceptions of diesel powered cars in the 80's, we would see a lot more hi-performance diesels on the road today.

Mazda i-stop wins RJC Technology of the Year Award
by Sebastian Blanco, on Nov 18th 2009 at 9:53AM (AUTOBLOG GREEN)

It's not the sexist part of a modern, efficient vehicle, but anti-idling tech is pretty darn useful. The Automotive Researchers' and Journalists' Conference of Japan (RJC) thinks so, and has picked Mazda's i-stop as its Technology of the Year for 2009. I-stop is a system that shuts down the engine when the car has stopped, much like the Stop&Start Micro-Hybrid system (which won the 2008 Automechanika Innovation Award) found in Daimler cars, Audi's start stop system, Fiat's start stop system, and, oh you get the picture. Everyone's doing it.

I-stop is pretty fast, able to restart the engine about a third of a second, and Mazda says it reduces fuel consumption by about 15 percent in a vehicle like the Mazda3 (aka Mazda Axela). In 2007, RJC picked Volkswagen's TSI engine technology as the Technology of the Year.

Hey spicejax, I don't think that trying to retrofit for MHD would be very cost effective, sorry dude. That kind of transformation would probably be very expensive. Also, thats why this feature was deemed not practical for the US market, in that the cost per car would put it at a price point disadvatage versus the fuel savings available to the average US driver. This info was from Dave S.

Thank you spicejax.

Thank you for not confusing me with the Bad Rob. ;^) And yes I realize I misspelled the word brake but I do know that fortwos have only two seats.

@Good Rob, excellent rundown on Hybrids. BTW, Bad Rob is back at it. Up to 87 comments 87 now. lol

@ Jan in West U

There is today only 1 maybe 2 hybrids that can turn their engine off at 40 mph and below.

One I know for a fact and that is the Prius. I own a 2008 model and if you have a light touch on the accelerator you can drive the Prius up to 40 mph on electric only for a few miles (10 to 15 minutes) until the battery gets too low and the engine fires up to recharge it (assuming you don't roll down a hill and recharge the battery). The Prius III (2010 model) now has an electric mode that forces the car to run electric only. So now you don't need to coax it to run electric with the accelerator pedal. I think this is an improvement.

I've heard the Honda Civic can drive with just the electric but it is difficult to convince it to do it. Of the two cars only the Prius actually starts from a dead stop with the electric and then starts the motor if necessary. All other hybrids start their engine as soon as you release the break.

So we can see there are at least three types of hybrids (until the Chevrolet Volt is released next year).

1) Start/Stop technology. smart mhd
2) Start/Stop technology with Electric Acceleration assistance: most hybrids.
3) Start/Stop technology with independent Electric/Gas/Both operation with primary as Gas: Prius. (Also called a true hybrid.)

The final category is the Volt.
4) Independent Electric/Gas/Both operation with primary as Electric. (It is a true hybrid also.)

All of these help to improve gas mileage, but the most efficient will be the car that uses the most electric to power the car.

@ jwight Thanks for the Link to the SCOA forum. Very interesting discussion, it looked like it said that the CDI wasn't coming over and the MHD is, but that was in 2008 and changes happen. lol The talk about bumper to bumper type, stop and go traffic was something I didn't dwell on, but it does make me wonder. As far as stoplights, I see no problems. Thanks again

@JohnnyM
-Thanks for your input on this. I wanted I a ED smart in the first place, but the CARS program enticed me. No regrets. I wondered since the smart has everything controlled by computer that maybe a 'retrofit MHD' could happen. I know that 2012 will bring new smarties and I hope MHD and ED will get here. I'm just a typical impatient American, I want it now! lol BTW, how do you know it won't come here sooner? Just curious.

Sorry dude, the MHD will not be coming to the USA in the near future. It was decided that this feature was not that practical for drivers in the US considering the added cost per vehicle. The smart ED will be coming to the USA and as a fully electric vehicle using Tesla battery technology sounds to be an interesting alternative to the gasoline powered version.
