Would love a bit more information about the Batteries.
200+ range sounds too good to be true but could prove a game changer if the claims are accurate.
The ranges on these are correct Kenny, the 200 miles easy to achieve and even 300 miles with care. There's a big difference in the battery technology between the Tesla models and such as the Nissan Leaf and Renault Zoe which have ranges often well below 100 miles.
Those last two use li-ion laminate cells somewhat similar to the cells in many of our e-bike batteries of ten years ago. For example,
this Phylion one from back then used ten large rectangular cells of 10 Ah each, while today's batteries often use as many as 50 or more industry standard 18650 cells which is far more efficient.
And that's these car differences. The Nissan Leaf uses just 192 large flat cells, but a Tesla model uses typically 6200 of the smaller high efficiency 18650 cells.
Of course this makes a vast difference to the car prices, the Tesla needs a very complex BMS and charging arrangement to cope with all those cells and keep them in balance and the cost of the 6200 cells is very high. Rounded existing Tesla car prices are £60k to £90k and battery replacement time will really hurt too!

. It was for the base model Visia and was only from two northern dealers. It hasn't been valid since. Those in my southern area were considerably higher.
