Any EV - You think your fuel economy doesn't match claims? - craig-pd130

I was browsing the road test of the new Tesla Model X in Autocar magazine, and happened to notice the disparity between Tesla's claimed range, and the range the testers managed.

Claimed: 303 miles

Actual: 147 miles

So not ideal for longer trips unless you can spare an hour or so to top up the batteries, then (and assuming you can actually find a charging point that's available).

Ouch !

I know someone who's actually put down a deposit on the forthcoming 'Model 3", on the assumption that the range will be as high as they were initially claiming (200+ miles). If that's going to be halved then he won't be happy

Most tests and review videos of electric vehicles I've watched suggest that the real-world range is a bit lower than the manufacturer's 'up-to' figures, but nothing like the disparity quoted above.

And even if manufacturer's claims for EV's are a bit optimistic, that's no different from petrol and diesel cars, where the quoted mpg figures are usually higher than what people get in everyday driving.

Also what sort of driving style were the testers employing? If they were doing flat-out motoring journo type driving, then they'd expect to get much worse economy, as they would with a petrol or diesel.

Having read the Autocar review, their figures relate to 70mph motorway cruising - about as good as it gets - means that real world averages would be even lower.

And in winter, lower still no doubt..- MUCH lower if you use the heater and lights..

This is what I was pointing out in my original post. You're right, it wasn't clear from the test if the 147 miles included the performance testing etc.

The test DID go on to say that at the power consumption stated on the car's readout at a steady 70mph m/way cruise, they would estimate perhaps 180 miles between charges.

The problem with the Tesla is, it takes an hour for a 90% charge at one of the 30 - yes, only thirty - 'supercharger' points in the UK. If you don't have one of those, you're waiting 2 - 3 hours to get meaningful range into the batteries from a high-output charger (such as at a service station). They really need a range extender, I think. Not that Mr Musk cares.

Forget about the mileage claims for a moment - what about the (at least) rear seat doors: how do you get out when a car is parked close to yours? From the photo on Autocar, the door has to be given about 2-3ft of space (at least) to open enough for someone other than a contortionist to get out...oh dear.

Now there you do have a point! I want Tesla to succeed and I like the look of their cars and I do think that electric cars are the future - as long as they don't have un-necessarily complex rear doors, that is!

They hinge up first before swinging open if parked close to something.

Here's another www.youtube.com/watch?v=B1KuiUk2Rqk - skip to about 5 mins when the doors open.

I should imagine that Tesla designed their rear doors with American car parks in mind. Our UK car park templates were designed, decades ago, for cars that were narrower than they are now. Theirs were designed for huge great bechromed behemoths with fins, much wider than the average modern American car.

UK buyers drive cars imported from all over the world - but US cars have had limited success over here, and then only when there wasn't yet much competition (Jeep Cherokee, and perhaps the RHD Ford Mustang). If it turns out that Teslas have a range that isn't much better than, say, a Zoe or e-Golf, there'll be a lot of cancelled orders.

Second video from Merlin's post above was interesting, second time he showed off the opening doors the RH door was noticeable slower and didn't fully open either.

Is it just me who would be extremely wary of going under those doors, what could possibly go wrong as wear and tear takes its toll.

My prediction is that in a few years time Tesla, when Tesla bring out a replacement for the Model X, it will have conventional rear doors!

...and you can buy a lot of petrol for the annual £15+k annual depreciation. The "back of an envelope" should be supplied to all motorists considering an EV

The What Car table suggests that both the Nissan Leaf and the Renault Zoe will be worth just 17% of their cost after three years. That's even worse than a big Citroen, which I hadn't thought was possible.

Used Leafs are a tremendous bargain for sure. Very pleased with mine. The finance companies writing PCPs on new ones have taken some stupendous losses.
