Electric cars and racing can make strange bedfellows.

The purpose of electric cars is to save energy. Racing, whether it uses gasoline or electrons, is a spectacle of speed—conservation takes a backseat.

DON'T MISS: Volkswagen's ID R Pikes Peak race car shows why you should care about electric car racing

As electric cars have gained a foothold in public consciousness—and as automakers try to strengthen that foothold—we've seen more electric cars involved in racing.

Volkswagen tackled Pikes Peak with an electric hill-climb car last month and shattered the course record.

The National Hot Rod Association, which sanctions drag races, may add a new electric racing class.

And FIA, which hosts Formula E street races around the world is preparing to start its fifth season—for the first time with batteries big enough to last the whole race.

With all that activity, we thought it was time to ask our Twitter followers what kind of electric car racing would interest them. 

Specifically, our question last week asked: "What type of electric-car racing interests you?" 

Almost half of our respondents, 46 percent, expressed some interest in Formula E.

Only 7 percent said they had any interest in electric drag racing, although if the popularity of YouTube videos showing Teslas dusting Dodge Challengers and Lamborghinis is any indication, this might not be indicative of the broader American public.

After VW's performance at Pikes Peak a surprising 17 percent of our Twitter followers expressed an interest in hill climbs or other types of electric car racing, perhaps some that organizers have yet to consider.

In all, 70 percent of our poll respondents expressed an interest in some type of electric car racing.

The second-most popular response with 30 percent of our votes was "none," perhaps indicating that those respondents take saving energy especially seriously.

As always, remember that our Twitter polls are unscientific, because of our low sample size and because our Twitter respondents are self-selected.
