While the static air resistance in the tunnel would be similar, you have many more variables in the 'open air' than in a tunnel. Traffic wind, 18-wheelers, cross winds, rain, snow, varying road quality leading to varying rolling resistance. I just think it looks like they really went out of their way to test unrealistic conditions. I don't personally own a 100+ mile tunnel of my own, so this exercise is not only pointless, it takes time away from valid ones... (Unless I'm in the minority, and each of you have your own personal tunnels, in which case, awesome, I want to check them out)!

One could even consider the more consistent temp in the tunnel, which would increase range by not having to run the AC/Heat as hard as you would 'outside'.

To Jag's credit, this is probably the world's first car test that occurred 'indoors'. You know, where most cars are used...


I still like the iPace, but it just wreaks of desperation. They are trying so hard to prove it's a 'real car', it comes off as detrimental... I wonder if anyone from Jag reads this site.

Wiki says the Eurotunnel is just 31 miles. Test seemed fun to me. No public access to that tunnel anyway.
My perception I-Pace is not exactly an economy car.

Some very entertaining commentary here. So, credit to the authors. Also, I think drivers in some regions might experience tunnels on a daily basis, no?


Anyway, similarly curious folks at the UK forum made inquiries with JLR. Here's a response:


"An average speed measurement was not taken, but this test was conducted on a variety of different roads and the driver took care to drive as they would normally. It was essential that our drive was representative of real-world use, not ‘hypermiling’ with comfort features such as climate control switched off. The aim of this activity was not to try and get the best range possible, but to showcase I-PACE's everyday usability."

All I know is my S was EPA rated for 300wH/mile. I averaged 365 across 50,000 miles. I admit I also took down rear tires at a rate of new tires every 10,000 miles...

A test for me would be set the (equivalent of) auto pilot to 85 mph and go for my usual weekend trip... comparing it to our Model 3. Takes a lot of the human factor out of it... which is exactly how the 3 is driven.
So far the Model 3 is a range machine. It just keeps going. I'll get the lifetime wH/mile when I get home. It has over 12,000 miles on it now.

For me, 200+ will likely comprise no more than 5 out of hundreds of trips per year. . .
200 miles is exactly what I want. The Bolt is rated at 238, and I got 200 per charge driving as fast and as inefficiently as I want. I don't ever want to have to worry about power usage in a car, and 200 miles real world range does it for me. I never go more than about 160 in a day, unless it's a long trip where I'll be taking the big gas guzzler anyway. EVs are still city cars for the foreseeable future, even Teslas. So if the I-Pace delivers a solid 200 miles, that works for me. If it's less, I'd pass and wait for something better - life is just too short to waste any of it on range anxiety.

Clearly, for long, long, long range drivers, the i-Pace isn't the best choice. Go get a Tesla 100D, a diesel sedan, or a small engined, efficiency geared pickup with a 30+ gallon tank.

Tesla has been offering some fairly serious discounts on inventory Model S and X's the last few weeks as well.

lol "city cars"? I drove my Model S places because of the super charger network.

Places I'd never been before. All over the freaking place. 60,000 miles worth of places.

www.supercharge.info exactly where can't you go?


at 14 MPG in my current ride (until I pick up an EV-SUV) I'll tell you where I don't go now... anywhere. it's too **** expensive! (we take the 3)

Every year I go the 500 miles between Las Vegas and Twin Falls on hwy 93. Yes you can go around to Salt lake but then you are going 150 miles out of your way.

The bottom line is, until the technology advances to the point where you can fully recharge your battery in 5-10 minutes at charging stations located at every exit on any highway, long distance travel in any EV is not going to be as convenient as it is with an ICE. Sure, absolutely, doing it in a 3 or an S is easier than an I Pace. I will totally grant that point. But it's still not nearly as easy as doing it in, say, a Toyota Camry. You just have to decide what you need the vehicle for and what trade-offs you're willing/able to make. For me, personally, I'm only using it to get to work, go around town and occasionally make a 100-mile trip to my place in the mountains (where I have a charger in my garage). So the I-Pace is perfect. Especially with the AWD and off-road capabilities. But that's me. Clearly others have different needs/priorities and this car doesn't work for them. That's fine. It doesn't mean it's a crappy car. Just means it doesn't meet their needs. (It meets mine.)
