The reason the L500R is so much faster than the other cars in Daily Race B is because it starts with a full hybrid battery. With that battery, in laps 1 through 3, it can have the hybrid boost down an entire straight, easily overpowering any gas car. But on lap 4, when the battery is drained and only recharges through braking, it's not much faster than any other car! So the fix to the balance of Race B and any other future similar race is simple: just make hybrids start with an empty battery! This way, there's no need to ban any car or change the parameters of the race, just remove the unfair advantage of a built-in extra boost.
