IndyCar announces downsized, boosted engines for 2012, KERS possible
Following last weekend’s running of the Indianapolis 500, the Indy Racing League announced that when its next-generation engine rules go into effect, smaller displacement, boosted engines would replace the current, normally aspirated 3.5-liter V8 engines. The specifics of the new powertrain package still need to be ironed out, but displacements will be limited to 2.4-liters with no more than six cylinders.
By allowing more architecture flexibility, the series hopes to attract more manufacturers to build powerplants. For the last several years, all of the IndyCar engines have been supplied by Honda. IndyCar will also be taking a page from the American Le Mans Series with some green initiatives like adding kinetic energy recovery hybrid systems (KERS) and other fuel efficiency technologies.
