Mission 1: Beat range anxiety
Can you make a 240-mile journey with only one stop? Change speed, charge target, and battery size until the plan works.
Mission 2: Money detective
If electricity costs 28p per kWh, multiply the energy used by £0.28. Compare that with a petrol car doing 45 mpg.
Mission 3: Engineer's question
Why does driving faster reduce range? Hint: pushing air out of the way takes much more energy at high speed.
