#ir28
Something important here that is glossed over, MSR will be doing the IndyCar development work for Honda. That is likely going to be a full year of on-track testing to get the IR28 ready.

Still a bummer MSR won’t be in IMSA. Seems a bit shortsighted considering the expenses they have absorbed.
Mike Shank has ruled out remaining in the IMSA WeatherTech SportsCar Championship next year, after initially exploring options for customer programs in the GT and LMP2 ranks but admitted he would only want to continue “at the highest level.”

It’s raining now. The IR28 test might be over for the day

I think the IR28 looks really nice but not nicer than the IR18. I think it's the perfect modern step forward. I just don't know what to think about the aeroscreen being so wide. Looks a bit out of proportion to the dimensions of the rest of the car. Probably duo to acomodating more space for drivers

My very unofficial time for the most recent IR28 oval laps. The fast lap of the 2026 Indy 500 was 39.978.

What engine was in the IR28 for Palou and Rossi's IMS test ?

Did Rossi test a chevy powered IR28 and Palou a Honda powered IR28 ?

Per Kevin Lee on Palou’s IR28 test today:

“I had Alex Palou's last 2 laps in the 1:10.7s - which is about :01.4 faster than fastest race lap this year in Indy GP & only about 1/2 second off pole...& he's on the hard tire, no hybrid & not pushing!”

Alexander Rossi said the power steering assistance in the IR28 is so they can future proof the car for a possible direction the series is going.

Anyone hear that and can read between the lines? It seems like he’s suggesting a possible horsepower increase.

My understanding is most of the IR28 parts will be made in Italy still.

I thought the whole IR28 release might be a good time to jump back in, or maybe blog Indycar a bit again but I really don’t feel it.
