Are there EVs that can do 350-400 km on highways at 120 kmhr?

Is there any performance EV that can make long trips at goosd speeds without getting into range anxiety?

BHPian rajarajacola recently shared this with other enthusiasts.

I found EVs like the EV6 to be very compelling products.

One requirement in my mind is that it should be able to travel from Bangalore to Ooty on a single charge. This would be ~350km and include around 50km of a steep mountain climb

Based on what I have read, these cars can do ~400km at 100km. From another thread:

I had done a real world range test of the following cars at 100Kmph. The city range will be higher. Hope it provides a perspective.

  • Hyundai IONIQ5 RWD- 430Km
  • Kia EV6 AWD- 420Km
  • Volvo C40 Recharge Twin - 400Km
  • BYD Atto 3 - 400Km
  • Volvo XC40 Recharge Twin - 350Km
  • Mercedes Benz EQB350 4Matic - 350Km

What if we were driving in an even more spirited manner (hypothetically hitting higher speeds when the roads are clear), and zipping up the mountain?

Is there any performance EV that can make the trip without getting into range anxiety?

Here's what GTO had to say on the matter:

Not happening at higher speeds with the current generation of EVs. Even Teslas - which offer the best EV drivetrains in the world - have owners complaining on Reddit if they cruise at 90 mph on freeways in the USA instead of 70-75 mph.

The sweet spot for range is 80 - 100 kmph for most EVs. At 120 kmph and up, the range drops drastically. Climbing up mountains also significantly reduces range.

If this is what you want:

  • Wait for the 700 - 800 km range EVs. They are coming.
  • Wait for EVs with a second gear ratio for highway cruising, like the Porsche Taycan whose 2nd taller gear kicks in at 80 kmph. This makes a big difference to highway range.

Here's what BHPian Shreyans_Jain had to say on the matter:

The best real world range is provided by the Kia EV6, which realistically does 400-450km at speeds of around 120kmph. Any faster, and this figure drops drastically. Conversely, if you drive at around 80-110, like it is on most Indian highways, you are looking at 500km.

Hill climbing also kills range. On my recent trip to Shimla, my Nexon EV LR did Solan to Theog, approx 75km, using over 50% of the battery. Consumption was twice what it was in the plains. On the way back, between gravity, regen and sparse traffic this took about than 15%.

Net net, the current crop is EVs is not suited to high speed expressway driving over long distances. It will take a major breakthrough in vehicle or battery technology to breach this limitation. Diesel is king for this particular requirement.

Here's what BHPian mally2 had to say on the matter:

just to put things in perspective, I have done Bangalore to Ooty in my Tiago EV albeit not in a single charge but one stop at Mysore while having breakfast for 45 mins, speeds across Blr Mysore Express way was 85-90 on cruise control and inside the Bandipur reserve along the forest area one cannot do more than 50 average, and once you ascend the main Ghat of Ooty one would be safer doing 30-50kmph. I did this whole trip in 6 hours including my 45 min charge break.

I have done similar trips to Chennai and Mangalore all needing just 1 stop onwards and 2 returning ( elevation to Bangalore is a  )

One does not need a 400+km range EV unless the plan is to do cross country trip like Bangalore - Delhi may be

Note - the Tiago does 180-190km for 100-15% on highways @85-90kmph @100-105 whkm

Here's what BHPian SKC-auto had to say on the matter:

Actually the biggest range killer is aero dynamics of the car.

As I have said before, ICE are so inefficient aerodynamics does not matter. It's like, say you have a 1 litre bottle which leaks, if a person has to run until no water left in the bottle, the only way to maximize the distance is to run fast.

EVs are very efficient, 5L(44kwh energy) equivalent petrol takes you 300km, so efficient having 2nd gear or even 5 gears does not matter for increasing range. Porsche taycan has 2nd gear to increase max speed.

Yes, future EVs will have more range by having lighter, denser batteries. The bottom line is to get say 1000km we probably need 150kwh battery.
