Nah. A bit further info. from What Car in the UK:
“Mini is fitting every car in its range with stop-start technology that switches off the engine when the vehicle is stationary, and an alternator that charges the battery during braking.”

That’s it. It doesn’t power the car forward. Therefore, I disagree to call those only equipped with start-stop tech ‘hybrids’. By definition, hybrid has to have more than one source of power, ICE & electric, or any combination of power of ‘more than’ ONE source.

The only thing that comes anywhere near close is the Ford Fusion…. come on Ford, market the heck out of that car! What on earth is your problem?! That really should be Ford’s biggest push, where all their advertising dollars go.

The Volt is a joke. A sad, sad joke.

Until the American car companies really try to make me a car I can get into, I’ll stick with the others, thanks.

I disagree. A Stop-Start is a Micro hybrid as stated in the article. If you can do regen braking, you can do propulsion assist. In fact you have to do assist. Otherwise, what do you do with the energy you recover during regen?

The problem is there is sometimes no clear cut boundary between these type of hybrids because all batteries/motors have different capacities and motors are put in different places (on a belt, between engine and trans, after trans, on a different axle, etc) . This complicates the definition of what type of hybrid it is.

“The tire was off the rim and there was no spare. You see, to reduce weight and improve mileage, some clever engineer decided to forego the spare tire in favor of run-flat tires and an inflator kit.”

–And yet the Volt still weighs in at a portly 3800lbs. or about 750lbs. more than the Prius. Some say that it’s because GM wants the car to have a solid on the road feeling. Others say it’s because GM doesn’t know how to make a lightweight passenger car. Just look at the Camaro convertible. It weighs in at 4200lbs. which is 300lbs. more than the hardtop.

As the Volt eased down the driveway that morning, I felt good. The gas tank was full. The video-game display on the dash said the battery was fully charged and good for 31 miles. And I was headed to one of my favorite breakfast joints. [...]

Suddenly, a pothole jarred me back to my senses.

Dawn was still just a promise, but I didn’t need to see the left front wheel to know the tire was flat. I wheeled the car into a safe parking lot, where I planned to change the tire.

That’s when the Volt broke my heart.

The tire was off the rim and there was no spare. You see, to reduce weight and improve mileage, some clever engineer decided to forego the spare tire in favor of run-flat tires and an inflator kit.

Bad choice.

The company that manages GM’s press fleet sent a man who swapped wheels and reprogrammed the Volt’s electronics to accept the new one. About 75 minutes after the pothole, I was on my way.

But I missed breakfast. And I’ll never again think of the Volt in quite the same way.”

I am impressed with Hyundai’s Elantra. All models get up to 40 mpg. Not just certain trim levels.

I’ll stick to my 2nd gen Prius. It’s currently averaging 48.1 mpg. I drive 31 miles round trip to work. 15 of those miles is on the highway. On the weekends I add about another 150 miles and that’s about 95% in and around town driving. Buying my next car will be hard because I’m used to getting superb gas mileage. I’m guessing a plug-in Prius is what I might be getting next.

- Is this some sort of “presbyopia”?
- I think the ONLY real BEV available for sale in the U.S. right now is Nissan LEAF;
- All other automakers do NOT have any BEV available in the U.S., including GM, Ford and Chrysler;
- Volt is just a hybrid with a large size battery strapped on (according to CR: “…when you look at the finances, for us it doesn’t make any sense… consumers seeking value and top fuel efficiency would be better off buying a top-performing gasoline/electric hybrid…”)
- CR also found Volt “fell well short of its maximum range potential under battery power”, the Volt CR tested ran for 26 miles before the vehicle’s gasoline engine kicked in;
- Was this an isolated case? Was CR particularly harsh on GM’s product? According to a driver of Volt who covered over 4,00 miles, from the end of December to late January, the average EV range was 26.2 miles when the average ambient temperature was 29.2 degree;

- So how about Nissan LEAF?
- There were media reports that customers reported restart problems in both Japan and the United States;
- if this problem is proven to be wide-spread, I would rather automakers thoroughly ‘debug’ their products than to pay to be the unfortunate guinea pig.

Stop-start: Has stop-start system
Micro-hybrid: Has stop-start system + regenerative braking
Mild-hybrid: Has stop-start system + regenerative braking + propulsion assist
Full-hybrid: Has stop-start system + regenerative braking + propulsion assist + all-electric proplusion

To answer your last question, I proposed the following definition in an article (in the International Journal of Electric and Hybrid Vehicles):
“A road vehicle with two or more energy storage systems connected to two or more energy converters. There must be a capacity for energy transfer in at least one direction between each energy converter and the wheels, but not all energy converters must provide direct, mechanical propulsion power.”

This definition is worded to include micro-hybrids but preclude dual-fuel vehicles like the BMW Hydrogen 7 and EVs with in-wheel motors (the SAE definitions missed these distinctions).
