I know the Ocean One and the Extreme are rated at 350 miles as per EPA standard.

My Mach E AWD standard range is rated at 211 EPA but in the summer, I am getting anywhere between 225-230 miles on 100% charge (12-18 miles over without preconditioning). Considering Mach E is equipped with 19" alloy wheels and also getting batteries from the same supplier (CATL), I am assuming the Ocean would easily get more than 350 Miles on the road.

What is the experience of other EV owners in the EPA range?

@ashutosh08824 Small point - the 350 miles is estimated, they have not been rated yet (however, assuming they used the EPA standards to calculate, it should be at 350 or above).  This is also based on the 20" wheels; HF estimates range from the 22" will be about 20 miles less.

Having said that, I find EPA range testing to be very inaccurate from car to car.  When comparing car to car, I prefer looking at the WLTP (the WLTP is extremely optimistic, however, it does a much better job of side by side comparison).  Below is a chart a few cars for EPA vs WLTP.  As you can see in the chart; the Model Y has 53 miles more EPA than the Mach E AWR ER, yet the WLTP is lower.  There is a member on a different forum who owns both cars and confirms he gets about the same range on both cars in real world driving.

Comparing the Ford SR to the Ocean, Ford WLTP is 18% more vs the Ocean of 11.4%.  If you can get 5-10% better range than EPA in your Mach E, my guess is that in the Ocean you will able to achieve 330-350 miles (assuming you have the 20" wheels).

Personally, I manage to achieve EPA range on my Model 3 RWD LR.  I can usually beat the range in the winter being in L.A. as we don't need heating or AC and typically can't travel above 75 mph due to traffic.  September/October days that are over 100° definitely affect range (especially if multiple shorter drives).  Tesla has played with the range figures over the years for the M3 so can't get a good comparison of EPA vs WLTP for the 3 but I am also expecting getting 330-350 miles on the Ocean.

Yes, the Mach-E is one of the few EVs that gets better than EPA on the highway. Link

Hopefully, the Ocean is closer to the Mach-E than Tesla.  The only time I got EPA on the highway is travelling at 55 MPH going on country highways.  Most of the time, I get 70-90% of the rated range (depending on the time of year/MPH/etc).

i think it’s important to qualify the conditions under which ranges are quoted by users.  I have a Tesla model S and a Mercedes EQS with both having an EPA range of 350 miles.  For around town driving, the Tesla and Mercedes both beat the EPA range.  However on freeway, with average speed of 70-mph, the Mercedes’ EQS goes an extra 70 miles compared o the Tesla.  Freeway range is really what matters because, not even the busiest soccer mom, drives 300 miles in a single day.

I have a feeling when it comes down to it our range will be closer to the 390 that gets advertised in Europe spec cars.

Is there any reason to believe range will be higher or lower?  I’m one of those that desire a minimum range of 300 miles?. EVs in the past have always stated that they would achieve more than what is actually produced I.e. Mach 1. 

Thoughts?

EV range unlike ICE is determined by below main factors

1) Weather - drop in range 10% with the heating ON in Winter 

2) Driving style - Consistent Aggressive (>75 mph) drving with heavy foot

3) HWY v/s City Driving 

I expect Ocean One / Extreme to hold the +330 miles range (22" wheels) and +350 miles range (20" wheel) under ideal conditions since actual range is slightly higher than the EPA.

ICE range/mpg is determined by the exact same factors. In ICE, the summer AC is a much bigger drag than in an EV, and the winter heat is a lower penalty because an ICE generates so much waste heat anyway so weather effects are significant but seasonally reversed. Rest is the same.

Why oh why are people so obsessed with range and not Efficiency.  

It's no good the fisker ocean doing 300 mile if the battery is, let's say 110kwh.

You want 300 from a 80kw/h battery for instance. 

We all need to wait and see what size the battery is. Then decide if the vehicle is going to be efficient against the predicted range. 

Look at the audi Etron ..... ridiculous range for the battery size.

Just my thought

@davea999 absolutely 100% agree. Its like when the diesel pickups boast they have 500 miles of range but never seem to mention that they also have 30 gallon fuel tanks…

Will I get my Fisker One delivered before my VW needs its 100K service?? The race is on..
and…… will we still get the $7500 tax credit? Only HF knows…

I consider both, however, I would be very happy if the battery is 110 kWh net - that would be an efficiency of 314 Wh/mi.  Based on projected weight, Cd, and huge wheels; my hope is for 333 Wh/mi (3 miles per kWh) which would have the battery at 115-120 kWh.  I would not be surprised if the battery is even 130-140 kWh.

350 miles with an 80 kWh battery would be 228 Wh/mi.  That would be better than almost all cars in the market right now (and that is including Tesla's make believe EPA ranges).

Absolutely spot on. 

I know the fisker is a biggish car, depending on where in the world you are but if the software is fine tuned and the BMS is super clever and the motors are the latest tech available then why not hope for a something like a genuine 350 mle range with a 80 -85 kw/h battery. More miles more smiles less pennies to spend

I am not sure why Fisker is not releasing the battery details since that setup must have been finalized long time ago and every preproduction car that is being produced now by Magna (for marketing and service training) already has the battery installed.

I think that you design the first product with contingencies to make sure to meet final specs even with all the unknowns going into the equation.  The relevant spec is range and not efficiency nor battery size.  A miss on the range spec would spell disaster for Fisker.  Efficiency can be measured but the actual range of the finished product needs - the finished product.  The only variable Fisker has to play with is battery size. So, the first models may come with bigger than necessary batteries as tweaking of the finished product is done and later, battery size reduced while maintaining range.
