POUGHKEEPSIE, NY March 16, 2010 – More than ever in these environmentally centered times, racing needs to lead by example. Dyson Racing is pleased to announce it will campaign its BP Castrol Mazda LMP2 coupe in the 2010 American Le Mans Series on BP’s bio race fuel utilizing isobutanol and ethanol. The team ran the advanced fuel in the #16 car of Chris Dyson and Guy Smith the last two races of the 2009 season. Based on that successful test, the ALMS has approved the isobutanol fuel for use this year in the prototype classes. This marks the fifth year running that the ALMS has added a new energy source.

“Extensive research between BP, Mazda, and Advanced Engine Research has given Dyson Racing and the series an advanced fuel that will help influence how bio fuels are developed for the consumer,” said Chris Dyson. “Our alignment with BP and Castrol works well because they use racing as a platform for developing new technologies in a rapid and advancing atmosphere. Technologies and fuels used in the ALMS are setting the stage for positive ecological developments for consumer cars in the future. It is very exciting for Dyson Racing and all of our partners to be at the cutting edge of this exciting and relevant technology.”

ISOBUTANOL FACTS: • Isobutanol has a higher energy content than many first generation biofuels; • Isobutanol does not absorb water and can be transported through the existing oil and gasoline distribution infrastructure; • Isobutanol can be used in gasoline-powered vehicles without modification at higher volumes than first generation biofuels, enabling greater concentrations of renewables into the transport fuel mix.

PRODUCTION: • Initially, isobutanol will be produced from feedstocks such as corn and sugarcane. Subsequently, isobutanol production can be based on cellulosic feedstocks and, eventually, advanced feedstocks such as macroalgae. • More information about Butamax™ Advanced Biofuels LLC, the BP-DuPont joint venture to commercialize isobutanol, can be found at: http://www.butamax.com.

ENVIRONMENTAL BENEFITS: • Initial indications are that, on the same feedstock basis, isobutanol delivers emission reductions that are at least as good as ethanol. • Isobutanol’s low vapor pressure (lower than gasoline), means that vapor pressure specifications do not need to be compromised.

Chris Dyson, Guy Smith and Andy Meyrick will drive the #16 Lola Mazda coupe with isobutnaol power at the season-opening 58th Mobil 1 Twelve Hours of Sebring on Saturday, March 20. The green flag falls at 10:30 AM ET with live coverage on SPEED starting at 10:00 AM.
