I didn't think it was possible that a vehicle could have this much torque. During their "Next" conference, BMW unveiled an electric vehicle that's has some earth shattering numbers.

Covered by a 5-Series body, this experimental EV, nicknamed "Lucy," comes with 3 electric motors that's capable of 720 horsepower and up to 7,357 pound-feet of torque on the axles. Showcasing to everyone how EVs can be made to satisfy speed demons everywhere.

According to CNET

But you can also turn up the wick and make it feel like a total goddamn rocket. That's because, with everything set to max-power mode, this electrified 5 Series produces 720 horsepower and 848 pound-feet of torque.

A BMW engineer originally told me the torque output was "around 10,000 Newton-meters on the axles," which would equate to an absolutely staggering 7,357 pound-feet. A different engineer clarified that the actual powertrain torque is "1,150 Newton-meters," or 848 pound-feet. Axle torque, or wheel torque, is different from the actual power being produced from the motors themselves; Jason Fenske from Engineering Explained does a good job of breaking down the difference. In other words, while the 7,357-pound-feet number is technically correct, the 848-pound-feet number is more accurate.

Even so, these numbers represent an increase of 103 horsepower and 295 pound-feet over the BMW M5 Competition. So no matter how you slice it, Lucy absolutely hauls. This tremendous thrust allows the 5,300-pound prototype to accelerate to 60 miles per hour in 2.8 seconds, and I'm told that number is actually a conservative estimate.

I assume pushing cars to these extreme limits is just for bragging rights amongst competitors since 99% of drivers will never test these limits and have nowhere to use them at their extremes. The newer 3/4 ton diesel trucks can work at 1,000 foot pounds pulling 21,000-22,000 pounds of trailer weight but for a passenger vehicle? At some point the compounds on tires will need to be reformulated for this abuse and will be too soft for regular street driving....:)

I'm curious how potent BMW can make the 5-Series EV in production form.

Already they announced all existing PHEV's will transition to EV's throughout the 2020, so lots of R&D is being poured into it, probably similar in proportion to VW Group.


more:

BMW’s new ‘eDrive Zone’ function will use geo-fencing technology to recognize emissions-free zones in urban areas and automatically switch your plug-in hybrid model’s driving mode to fully electric.

The German automaker is hoping that eDrive Zone will give PHEVs the same type of access rights as with fully electric models, since they will behave in the same exact way when entering specific areas. All BMW plug-in hybrids will behave this way starting next year.

Earn BMW Points

Aside from the eDrive Zone function, BMW is also looking to further stimulate drivers through the BMW Points app, which encourages PHEV customers to “get the most out of their electric drive.” What this means is that the miles you cover while in EV mode will be rewarded with points, as will high-voltage battery charging.

By collecting a large enough number of points, participants can then gain access to rewards such as free charging volumes on Charge Now – more rewards will be made available in the future (Share Now, Park Now).

This system has already been trialed by 50 volunteer plug-in hybrid drivers in Rotterdam, over a period of three months last year.

BMW is now on track to reach its goal of having 25 electrified models on the road by the year 2025, two years earlier, reports Autonews Europe. Also, more than half of these 25 models will be fully-electric.

“We are moving up a gear in the transformation toward sustainable mobility,” said BMW CEO Harald Krueger. “By 2021, we will have doubled our sales of electrified vehicles compared to 2019.”

Last year, the BMW Group sold a total of 142,617 electrified BMWs and Minis. By the end of this year, the automaker expects to reach an overall total of half a million electrified units sold.

According to BMW's head of development Klaus Frohlich, the only thing holding BMW back is customer demand, not technical restrictions. :rolleyes: - https://www.autocar.co.uk/car-news/new-cars/bmw-could-produce-100-electrified-models-2023-if-demand-was-there. I don't quite but that reasoning but it does seem like BMW is prepared to go all in on electric vehicles.

BMW “could launch 100 electrified cars by 2023” if customer demand was there to buy them, according to the firm’s head of development, Klaus Fröhlich. His comments coincided with today’s announcement that BMW is pulling forward its electrified launch goal of 25 new vehicles by two years.

Fröhlich says this is possible because of the flexibility of the firm’s modular fifth-generation architecture, which is designed to underpin battery, plug-in hybrid and engine applications. “What we have now is a jigsaw puzzle of technology, and we can fit the jigsaw together to provide whatever the customer needs,” he said.

“The decision to pull forward the production dates is simply driven by customer demand growing faster than expected. You saw the same flexibility with how we coped with the drop in demand for diesel. My team is reading; for each application, all it needs is a year for homologation work and a year for fine-tuning.”

All BMW has to do is coax the German Government and other Governments to make laws that everyone has to drive EV’s then their demand goes up automatically. Naturally countries that produce petroleum products will balk at the idea initially until forced to do so politically, if that is possible. Another problem will be electrical grids in many countries that may not be able to support additional demand to charge so many vehicles. Here in the U.S in hot Summer weather electrical demand for air conditioning is already at 100% so one wonders how millions of EV’s can be recharged at the same time even at night.

Well there's a reason why electric cars were stopped from taking off over a century ago ;) Its the same reason why everyone is going green now.
