the result will be the most energy—efficient five—seater on the market when it launches, with a ruthlessly aerodynamic design weighing about half a tesla model s, and which trades the crazy acceleration of that beast for range and efficiency. so, the tendency has been for electric cars to look at high acceleration and large batteries. so, because of those two, cars get very heavy, and very heavy cars that accelerate quickly, they need very high power. so, we say it's more important to get to the destination quick than it is to be quick at a traffic light. and what's great about in—wheel motors is that they are direct drive, so, basically, there's no gears at all. there's just four moving parts — four motors. that's it. so, it means that no heat is lost in drive shafts or other gears, etc. so, every bit of energy goes directly to the motors and to the wheels. and that makes it more efficient and therefore on the same amount of solar you get in, you can drive more.
