Top Alcohol

Commonly known as "alky" cars, both are akin in design to the premier Top Fuel classes, but less powerful (about 3,500 bhp (2,600 kW; 3,500 PS)).

[1] Top Alcohol Dragsters and Funny Cars resemble their nitromethane (Fuel) counterparts, with about half the power of their respective classes.

It was within IHRA's version of this class use of ethanol fuel was pioneered with great success by Mark Thomas, an Ohio farmer who became a five-time champion within that organization.

Despite this, ethanol has failed to capture the imagination of racers; the majority opt for more traditional methanol.

Top Alcohol classes also compete outside of North America, most notably in Australia and Europe.
