Indy electronics drive cars to be lighter, faster

While 200mph speeds are not uncommon for IZOD IndyCar racers, their electronic systems are in many ways simpler than those found in many passenger cars designed for public highway speeds. After all, these vehicles do not need an extensive infotainment system, climate control, or security electronics.

But such cars do require specialization in those systems that are onboard to allow teams to optimize performance while maximizing safety. Trevor Knowles, director of engine development for IndyCar and an expert on their electronic systems, notes the difference between IndyCar electronics and those in passenger cars in that racecar electronics are more customized than those in passenger cars because of the unique requirements and lower production numbers.
