"Gurss’ prose style is madly gripping and emotional, so that it feels like you’re part of it—an impressive feat for a writer who wasn’t even there! When parts of the engine fail at the very last second, I was sitting there holding my breath, a ball of dread in my stomach. When all three Penskes were absolutely killing it in Indy 500 practice, I was hyped enough that I was smiling."

Take the rest of the day off, Jade.”“Jade Gurss has shone a light into the shadows of the Skunk Works-style operation from which emerged one of the greatest machines in Indy car history.""This engine captured more notoriety for Ilmor and Team Penske than anything we have done together. Some people loved it, some hated it, but it's rare to meet anyone from that era of racing that doesn't have an opinion about it. Now everyone can read the truth and see the incredible effort it took to make it happen."“An incredible tale told from the perspective of those who made it happen."
