Only One Car Per Driver Required: The Second Generation Formula E Race Car
Looking at the design of the Second Generation Formula E car reminds me of the “Speed Racer” cartoons I watched as a kid. With the exception of having fenders, the Second Gen E still bears more of a resemblance to the cars in other Formula Series than the Mach 1.
The SGE features two major changes. To protect the driver from anything that gets kicked-up off the track during a race a device called a “halo” has been added.
Resembling a bent slingshot the halo consists of a V-shaped mount directly in front of the driver. Attached to that mount is a U-shaped rod that surrounds the driver level with the top of the head.
There are those who argue that the halo detracts from the car’s appearance. Looking at the location of the front support it seems the halo might interfere with the driver’s vision. While protecting the driver in one way there is concern that the halo would get in the way of extracting a driver after a wreck.
For its first four seasons, Formula E didn’t have a battery capable of holding enough juice to last the entire race. Since pit stops lasting 30 minutes-12 hours aren’t practical the drivers had to change cars mid-race.
The new batteries will not only go flag to flag but are more powerful. The original electrical storage unit produced 200kw. The new battery cranks out 250kW. That 50 extra kWs increases the car’s top end speed from 140 to 186 mph.
