Modern engines are more powerful, efficient, and technologically advanced than ever before—but are drivers unknowingly setting themselves up for expensive repairs? In this episode of https://Drive-Radio.com – The Extra Mile, John Rush takes a deep dive into the technology behind direct-injection (GDI) engines and turbochargers, explaining how modern vehicles squeeze incredible power and efficiency from smaller engines. John walks listeners through the evolution of fuel systems—from carburetors to throttle-body injection, port injection, and today’s direct-injection engines that inject fuel directly into the combustion chamber. While this design improves horsepower, fuel economy, and emissions performance, it also introduces new challenges—especially
