One of the main ways that gasoline-electric cars achieve better fuel efficiencies than typical gasoline-powered cars is through the use of __________.
solar panels on the roof to charge the car's battery better aerodynamic designs regenerative braking wind turbines to power onboard electric generators
One of the main ways that gasoline-electric cars achieve better fuel efficiencies than typical gasoline-powered cars is through the use of regenerative braking. This technology allows the car to recover energy that would otherwise be lost during braking and use it to recharge the battery, improving overall efficiency.
