First time eDrive and xDrive tech has been combined in one vehicle

BMW has unveiled the Concept X5 eDrive, which will be showcased at the New York International Auto Show. Although the vehicle is labeled as a concept, it’s a dead ringer for the production plug-in hybrid version of BMW’s popular crossover that it plans to bring to market sometime within the next year or two.
 
The hybrid drive system gets its primary motivation from a 245hp turbocharged 4-cylinder engine. That gas engine is combined with a 95hp/184 lb-ft electric motor developed by the BMW Group. Power for the electric motor comes from a lithium-ion battery pack (which is mounted under the cargo area) that can charge from any wall outlet.
 
The Concept X5 eDrive can drive on electricity alone for up to 20 miles at speeds up to 75 mph. BMW says that the car will have an average fuel consumption of over 74.3 mpg in the EU testing cycle (which means we’ll likely see less than half of that quoted figure under EPA guidelines). BMW says that the X5 concept can reach 62mph in under 7-seconds.

 
The Concept X5 eDrive is the first from BMW that uses its xDrive all-wheel-drive system paired with eDrive hybrid technology.
 
The concept also has a ConnectedDrive system that helps plan routes and lists the location of charging stations on the GPS map. This allows the driver to find a charging station when they are around town in electric mode.

Instant torque - irrelevant, since the engine produces no horsepower when it's not turning and it produces low horsepower when it is turning at low RPM. A gasoline engine also has "instant torque" as it is already idling at 800 RPM or so, and it has "instant horsepower" as well.
False. Torque accelerates a car; the heavier a car is, the more torque you need to reach a certain speed by a certain time. ICE engines do not produce "instant torque". When the OP says "instant torque", he/she means the tendency of electric engines to produce 100% of the torque at all RPMs. ICE engines don't do that; generally, ICE torque is 50% of the max at the lowest RPMs (generally 800-1,200) , peaks around 2,000-3,500, then drops to below 50% from 6,000 and beyond. The swing from 50%-100%-50% is what jerks the car during gear shifts up and pushes you back in the seat as you hold the gas.

Electric vehicles, producing 100% of the torque all of the time, generally lack the jerking and push back. Drivers have commented on how deceptive acceleration is in EVs since it's there, but you don't feel it. "Instant torque" makes acceleration smooth, something you can appreciate in a heavy vehicle.

Ridiculous performance - it is quite ridiculous, since driving it in conditions that do not have california-like weather will result in severely compromised run times.
The Model X isn't even in production yet. Wait until there are models on the road with recorded data before making these kinds of claims.

BTW, the OP meant the 4.4secs it's estimated to get to 60mph. That's better than many sports cars, and is comparable to some older supercars. Not bad for a car weighing more than 2,100kgs (that kind of performance is usually seen from a car weighing 1,400kgs with that amount of HP and a better aerodynamic drag coefficient).
quote:
Long ev range - the energy density of batteries is nowhere near that of gasoline or diesel, and it is unlikely to be anytime soon.
Which is why the OP said long EV range, as in "long for an EV." We have to see a real car in action, but the estimates are pretty good for a battery-only EV. Which invalidates the rest of your post, since Telsa doesn't create cars with gasoline generators...

Considering your posts in this article, it's clear that you're not only woefully ignorant of this topic you're also fond of rambling and attacking people who don't agree with you.

If there is anyone who is reading this thread and would like to know why everyone else disagrees with Eric's comments (or finds them not worth reading) I would be more than happy to explain in greater detail. There's no point it explaining it to him since he's spouting nonsense that can be debunked by an introductory book on automotive concepts and physics.

That's right, you're not able to refute anything I said because you know it's true so resort to making a sore loser comment like this.

The idiot thinks he's an authority on cars, or anything for that matter. Gotta say it adds a touch of humor to this whole bit.

Electric cars didn't work in the 1800s and nothing has changed now, 214 years later. The problems they had then are largely the same as the ones they have today.

I'm one of the more aggressive drivers on the road, from my point of view.

But not even I go around launching my car for the best 0-60 times possible, and I don't see anyone else doing it either in normal driving.

It's great that electric motors give you "max torque" and all that, but I don't know why EV proponents go on and on about it so much. People simply don't drive like that in real life, even if they can.

Having said that, I find pretty much all of Eric's posts here embarrassing. And that's coming from ME lol.

And yet in other threads, you deride the Tesla as having a low top speed compared to other models.

News flash, people use quick acceleration a lot more often than they drive at 125mph+, mostly because one is legal and the other isn't.

Yes because a car that costs that much is expected to have performance of a certain caliber, even if you never use it.

The Model S compared to cars in it's class has very poor interior amenities, and a pitiful top speed.

News flash, by any objective measure cars competing with the Model S have great acceleration as well.

Nobody cares about top speed in a full size sedan. If you go over 130mph on a public road outside Germany, you should have your license revoked.

This is more than "great" acceleration. MotorTrend has tested countless cars in it 45-65 passing test, and few are faster than the 1.7s that the Model S takes (even a Corvette Z51 is slower). None have as much interior room:

It's quicker than the S550, A7/A8, 650i Gran Coupe, Panamera GTS, etc. There's only one large car that can out-accelerate it under $120k, and it's barely any less. I'll leave it to you to figure that out.

Americans (and almost every buyer in this segment) have ALWAYS loved power, loved big cars, and loved good looks. Few cars match the Model S in acceleration, room, and appearance, and none under $100k.

That's why it's outselling its gas competitors, above all else (all other EV sales prove that the green factor barely helps at all). The sooner you realize that, the sooner you'll stop the nitpicking hate of Tesla.

Oh nice argument. Great supporting evidence too.

Well then I declare that "nobody" cares about acceleration in a full size sedan.

Ohhh, what now?

People don't buy Tesla's because it's a performance car. Get a clue. If it drove like a dump truck, Elon Musk would still be a hero.

Go find major reviews for the S-class, A8, 750i, etc where top speed is listed as a pro or con. Nobody cares.

Go find a review about such cars that doesn't talk about acceleration. It's a major review point.

Then why are so many people buying the performance version? Tesla's ASP is over $100k (google it), so most sales would have to be the P85 model ($93k base).

All other EVs have tiny market share in their segment, except for BYD's Qin PHEV (5.9s 0-60, ~$32k), which is selling faster than they can make them in China.

I think your missing the point.

The car buying public has general opinion that cars with low end torque are "premium".

Look no further than Chevy Cruze. The base 1.8 liter engine produces the same max horsepower as the 1.4 turbo engine. But the superior low end torque of the 1.4 liter engine gives the car better performance, more "premium" feel, and a higher price tag.

An electronic motor typically goes even further. In comparison to a gasoline engine of the same max horsepower, an electric engine will have better performance in most real world situations and will feel like the premium engine.

Having driven a NA gasoline, a turbo gasoline, and a electric motor all in the 150-175 max hp range in the last week, the electric is the car I'd prefer to drive daily (the Turbo still wins for pure fun).

You just put "premium" and Chevy Cruze in the same sentence....

For nearly $100k it damn sure better feel like a premium engine.

Go drive a Leaf, I don't see people accrediting that with a "premium" feel in ANY area.

Premium in comparison to the comparable gasoline engine. Given that a Leaf is a B-segment Hatchback. So... a Nissan Versa Note with a 109 max hp/107 max torque. Hmmm... I bet a Nissan Leaf's electric engine does feel like a significant upgrade if you drive it right after a Versa Note.

Constant fixation on a over estimate of an initial purchase price.

The Model S is pretty similiar to a BMW 5 series Gran Turismo. Once you consider TCO, they are nearly the same price, same size, and both are "4 door coupish hatches". Not sure the Model S is losing too many battles to the BMW 5 series Gran Turismo.

If you paid the premium for a fast car you should drive it fast. I'm at or near the redline quite routinely in my cars for no other reason than it's fun and I like the feeling I get.

High torque at low engine speeds, or with electric motors - zero engine speed, result in a car that "feels" fast because you feel that force pressing you back into the seat.

Despite this, the fastest Model S is only cutting high 12-sec quarter mile times...this is OK if you're in the $40K-$50K price range but it's on the slow side for something $80K plus.

The base Model S only does a low 14 sec pass...so all this hype about torque (which is heavily misunderstood by the average idiot) is for nothing.

Go ahead and show me were I'm wrong about anything I said, but don't embarrass yourself in trying to do so.
