Will the BMW i3 with not intended for use range extender meet US expectations?

Yesterday I was contacted by , senior editor of , kindly what I thought of a piece he comparing what is known of the BMW i3 with range extender to the Volt.

His article ponders BMW is possibly setting itself up for a new on “range anxiety” in the North market because the motorcycle-based petrol backup may not be enough to the output of the EV it is meant to support.

In view, the “ReX” range – its displacement may be 800cc but this is not – may lead the car to dip into its 21-22-kwh energy buffer.

Power may be in range-extended mode on a level but up long hills, or at speed, or in taxing scenarios, the performance may off in range-extended mode.

The i3’s motor is expected to deliver 170 (125 kw) of peak power to its wheels. A suitable ratio for the output would be 1:2. The is set up this way.

Its electric output is rated at 149 (111 kw), and its gas range is around half that at 74 (55 kw).

It’s not out of the question an 800cc BMW motorcycle-based engine be able to deliver half of the 170 horsepower of the i3’s traction but that would be pushing it. A twin from one of its liquid-cooled bikes is capable of 85-90 but usually they must be to around 8,900 rpm to achieve power.

Do you think BMW will the genset in the i3 a 9,000 rpm screamer? If its gas-to-electric ratio will be less than the Volt’s, and is assuming it’s an 800cc. BMW has a 650cc parallel twin engine, so this is an open

What is known to date is the design parameters set by BMW are not the same as GM with the Volt. The Volt, as you can be driven on gas alone if someone to do it, but the BMW’s tiny range may not be able to do this as well.

for example, a heavily loaded electric car on a 10-mile uphill at freeway speeds,” writes of a where the i3 may come up short in mode, “Once the buffer of the pack is depleted, would a 40- or generator be enough to keep the i3 at speed on that freeway?”

BMW has it expects the estimated 100 mile or so EV its i3 will provide will and so its range extender is there like a spare gas can to get the driver to a if needed.

The car’s fuel is only expected to be 2-3 gallons would only double the EV These decisions are being by BMW in order to comply with arcane requirements to still be a “zero-emissions vehicle” (even if it emit some hydrocarbons

One thing that’s true of engineers is they know the mindset, and what will drivers for the most part.

A may be seen in BMW’s philosophy as by BMW’s global RD chief, Diess, who was quoted recently the i3’s range extender is not to be used day in, day out, as the Volt’s extender is capable of.

“The extender is not intended for daily It s for situations when the driver to extend the range of the vehicle to the next charging station,” Diess. “Therefore, the i3 probably won t be the for customers with a need for an range.”


Instead, a plug-in hybrid be a better choice, Diess He also said BMW expects may flock to the range-extended version at but as the car becomes known, those for the range-extended i3 will diminish half of all buyers, to just

“It is more of an issue for those who not yet had a chance to use an electric car,” Diess of the range-extender option. a few days, they usually that a base range of miles] is sufficient to limit to about two times a week. In cases where people think they need a extender, it actually never is

BMW is making the i3 a global car aimed at Europe and Asia where traveled are more often and driver requirements are different in the U.S.

The i3 is due for U.S. delivery in 2014, and BMW says it will nothing as a family member of the Driving Machines.”

It may be an EV, but this will be a BMW EV, and presumably fun to drive than a Nissan But will the BMW wilt nonetheless in mode?

That is one mystery, but as there is room for speculation. the specific cost for the range-extender is not known. Word has been it be an additional $2,000-$3,000 more for the car priced in the $40,000 range.

If is so, this is not a lot extra for an installed and frankly it sounds too low.

To be we’ll need more from BMW, but judging what it is saying, do you think it is the American market, and what people would want? Why with a range extender if it meet power supply in full?

GM already gave what it thought was the best compromise – an EV that can travel on gas if needed – but BMW’s criteria appear to be up to the same standard.

Is it possible the i3 with range will be a near-miss for most Or could BMW re-think its priorities launching the car here in the land of expectations?
