Carbon E7: Diesel power
Carbon E7: Diesel power
Another way the Carbon E7 will save fuel, its creators claim, is by building things like flashing lights into the car's body rather than adding them as bolted-on protrusions that increase aerodynamic drag.

Carbon's plan for the cars includes taking them back after their service life is over. The cars will be stripped down and recycled. Some parts will be used to make new police cars. The cars will not be sent to used car auctions. That will prevent criminals from getting their hands on decommissioned cop cars.
