You live in CT. Simple answer is WINTER. 260, in the dead of winter, will be a dream. Your range will drop as temps drop and you build driving history. If you get 210 at 100% in 20 degree weather, that's good.
I think it really is a combination: In stop and go traffic you pick up range through regenerative braking, which on the highway you do not get. Of course the faster you go, the more air resistance and that reduces range. But the majority of "range kill" at highway speed below 65 mph is no regenerative braking.
I would disagree with this. Traveling at constant speed is the most efficient. It is air resistance or drag which scales with the square of your speed that gets you at highway speeds.
I agree. Out here and outside of urban areas the highway speeds are 65+ posted and most people seem to drive 5-10 over.
Agree with you but does not the aerodynamic force increase as the cube of the speed. That how I remember it from my daughters windmill science project.
Yeah, the drag force scales with velocity squared and the power required to overcome (F x V) scales as cubed. So, I guess in this case power is the more appropriate metric.
I have a similar problem. Range quoted when I bought the MacheGT was 270 miles, however it only charges to around 200. This discrepancy is too big to forgive.
I have a similar problem, the quoted range on my MacheGT was 270 miles, that's one reason I bought it. However it only charges to around 200 miles, that's too big of a discrepancy to ignore. I will ask at the dealer, but fear I will only get stonewalled......
See all the posts about range estimates in winter versus summer and versus driving habits. The weather has been mild in Dallas area lately and my GT often shows >3 mi/KWh on local trips (threshold for 270 mile range). But, I occasionally drive a bit aggressively and sometimes hit the highway and there have been cooler temperature periods and that reduces the range. Check your trip display versus driving conditions, but you need to drive for at least 10 minutes for it to give a reasonable average. Mine typically estimates 250 miles (212 at 85%) after a charge, but that estimate is based on recent driving history and current temperature.
Lots of info in your reference. So maybe at some lower speeds (laminar flow) the power req'd is proportional to v^2 but at turbulent flow is v^3. In reference to driving in a draft I remember some bicyclist achieving something like 125 mph by riding behind a truck with a canopy on its back end. Car shape is critical but we all don't want to drive vehicles that look like eggs.
What was the "range quoted" when you bought your gas powered vehicle?
I have been driving to Vermont for skiing for over 50 years: It is a fact that colder air is more dense than warmer air and denser air gives more power in an ICE than warmer air. If you check your tire pressure, which I do every time I drive, I find my mileage in the winter is actually better not worse, than driving in the summer: reason is pretty simple: the heat you get in an ICE in the winter is free. The AC you are running in the summer is not.
The reality is that most people don't research anything before they buy it. It's not just this forum, it's not just EVs. Some are lazy. Some don't understand enough to do the research. Some say they don't have the time. And some, well, ...
In cold weather it doesn’t charge to the fullest range.
I have had mine couple weeks, mine says 285 and we have 30 degrees here.
