E85, a blend of 85% ethanol and 15% gasoline, offers the potential for increased horsepower compared to standard gasoline due to its higher octane rating and cooler combustion temperatures. This can translate to notable performance gains, especially in vehicles specifically tuned for E85.
The magnitude of this power increase depends on several factors, including the engine’s design, modifications made to accommodate E85, and the specific tuning implemented. While E85 offers performance advantages, it’s essential to consider its lower energy content compared to gasoline, often resulting in reduced fuel economy. Historically, ethanol-based fuels have been explored as alternatives to gasoline, with interest driven by factors ranging from energy independence to environmental concerns. The development of flex-fuel vehicles capable of utilizing both gasoline and E85 blends marks a significant step in offering consumers fuel choices.
