The IndyCar series is due to adopt new engine rules soon and it looks like they will follow the lead of many manufacturers toward downsized and turbocharged engines. The open-wheeled racers that run at the Indianapolis 500 and many other tracks currently use a normally aspirated 3.0L V8 running on straight ethanol. A new engine formula is expected to go into effect for the 2011 season with a switch to turbo engines with either four or six cylinders.

The deal goes down at the GasAmerica at 5179 LaFayette Road. There will also be a drawing for a two-year l

The first truck carrying 100 percent fuel-grade ethanol bound for use in the IndyCar Series, which starts March 24, left the Renova ethanol plant in Torrington, Wyoming today. Indy's move to E100 is no secret – they cars used E10 all last year in preparation for this year's E100 switch – and new we're getting to brass tacks.
