I have a 85kWh Model S on loan while Tesla repair my Roadster following the latest breakdown.

I drove my regular ~180 mile trip last weekend and it looks as if the Model S is using twice as much energy as the Roadster.

This weekend I'm driving 500+ miles and will log the energy consumption more accurately but for now I believe the range predictor on the Tesla website is hopelessly optimistic...

 

[Kevin Sharpe]

Weather, driving style, road conditions, elevation changes. All that stuff factors in.

It was a typical autumn drive with no rain, light wind, speed limits observed, and the same route I've driven for the last 4+ years.

I have no doubt that the Model S 'typical' range is nothing like the figures quoted by Tesla on their website...

 

[Kevin Sharpe]

Typical Range. That's new to me. I've seen Rated Range and Ideal Range. I have to check my 6.0 closer.

We use New European Driving Cycle (here) not EPA. My lawyers tell me that "typical" has a very specific legal interpretation within the EU

Kevin looking at the graph in the photo your a little heavy footed, the darker Orange the more your thrashing it

Nope... A roads at peak time with less than 1 mile of dual carriageway so no chance to 'thrash it'.

 

[Kevin Sharpe]

I have seen 270 this was on a long haul motorway drive with last 40 on slower country roads.

Very long way from the 312 miles (NEDC) that Tesla quote on their website...

 

[Kevin Sharpe]

Agree but so does every manufacturer who quotes that, it's done at steady speed (55 I think) with no aircon, very unrealistic.

No, I could hit NEDC range in the Roadster but don't see any Model S owners achieving anything like that range... I will have a much better idea of real world range after this weekend.

 

[Kevin Sharpe]

I doubt anyone can hit that 312 mile limit because a 312 mile drive in flat roads at a constant 55 mph is just.... BORING.

The difference between 312 miles (that most people expect from Tesla marketing) and 239 miles (that the car is predicting) is huge and yet another Model S surprise

 

[Kevin Sharpe]

How does that differ from the marketing range of any other BEV in the UK showing the NEDC range being but achievable in the real world?

I'm comparing the real world experience of driving the Tesla Roadster against the Tesla Model S over a ~180 mile journey that I have driven many times in the last 4.5 years.

I believe the 312 mile NEDC range of the Model S is unachievable unlike the 211 mile NEDC range of the Roadster. My hunch is that the huge weight of the Model S is severely depressing the real world range.

 

[Kevin Sharpe]

Tesla quote real world range of much less than 312 miles on their website.

Where?

meaningless in legal context... only quoted NEDC range forms part of your contract with Tesla...

[Kevin Sharpe]

So presumably same would go for Leaf quoted at 124 miles range and most manufacturers quoting unachievable mpg figures?

Correct... but let's discuss this in another thread... This thread is for my real world Midel S experiences.

Charge rate at Birmingham supercharger is 21kW when two cars on charge

Given its a 40+ minute diversion from the motorway I'd suggest using the AC Rapids at the services...

 

[Kevin Sharpe]

it uses alot of juice getting itself moving.

Without a doubt that's why its so poor compared with the Roadster... I tried to cruise at 70mph on the motorway but heavy traffic put an end to that and the energy consumption soured as a result.

 

[Kevin Sharpe]

Depends on the SOC of the first car as the system allocates progressively more to the second car as the car fills up.

When I returned to the car after 1.5 hours a second Tesla had replaced the first and therefore in reality I spent a lot of time charging at ~21kW
