Chances are that just about every car you've ever owned featured some form of fuel injection, but the long-standard engine tech remains foreign territory in NASCAR. The sport has used carburetors since the racing series began in 1949, but that looks set to change later this year.

NASCAR reports on its website that fuel injection testing could happen as soon as July 7 at Kentucky Speedway. The date has been singled out due to the fact that this is the first time the Cup Series has raced there, and NASCAR has given racing teams an extra four hours of testing on the Thursday before the race.

Danny Lawrence, chief engine builder for Earnhardt-Childress Racing Engines, is hoping NASCAR comes up with specifications so the teams can prepare, adding "I know they're working on it really hard, and hopefully, they'll have it figured out in a few days."

NASCAR is working with McLaren and Freescale Semiconductor to develop and manufacture engine control units to manage fuel and ignition systems. A wiring harness has reportedly already been developed, and the fuel-injector specification will be the next step. Teams are still wondering at this point if they'll receive a specification for the fuel injection system or if NASCAR will provide systems that everyone must use. Hat tip to Pawager!
