BP's new Ultimate 102 boasts an octane rating of - you guessed it - 102, and is made in limited quantities by BP's Specialty Fuels Technology Centre, using the same techniques used to craft Formula 1 race fuel.
What's the point? The high-octane fuel typically boosts power output on modern performance cars by between 4 and 7.5 percent over BP's standard Ultimate 97, provided your ride is willing and able to remap its ignition and/or increase turbo boost.
Ultimate 102 has its own minisite here, and (this must be a first) the fuel will soon have its own blog here. The product is only available in the U.K., at least for now.
