IER P13 — IER Simulations

"It is amazing. It really lives up to all of the hype around it."

Jimmy Broadbent
"Driving the P13 is unlike any other car I've experienced in Assetto Corsa."

Chris Haye

IER P13c

IER's 2019 P13c project was a milestone in consumer simulation. New thermal models for the brakes and tires, a new aerodynamic model, variable motion ratios in the suspension, engine maps, advanced traction control, and more accurate fuel consumption were only a few of the car's standout features – none of which previously seen in Assetto Corsa.

Based on 2013 LMP1 regulations, the P13c represents the pinnacle of pre-hybrid prototype race cars. Its 600 horsepower naturally aspirated 3.4L V8 propels the 890 kg chassis to over 200mph, and its wide front tires and immense downforce allow cornering at well over 3G.

IER P13b

After a 4 year hiatus from the public sphere while working exclusively in professional motorsport, IER makes a brief return to the community from which it was founded 10 years ago. Like with the release of the P13c, the P13b lies at the cutting edge of CSP technology, providing a vital take on the abilities of IER in 2024. IER aims to provide a glimpse into the world of professional simulation through the lens of a public release.

Despite sharing its chassis with the P13c, the P13b features different suspension, steering, aerodynamics, tires, and engine—the shared DNA is apparent, but the car is unique in its own right.

Built around the 2013 LMP2 regulations with some LMP1 embellishments, the P13b expands upon a decade-old platform to provide a well-rounded and easily accessible car catered towards Pro-Am racing. Featuring a ~500hp 2.8L TT V6, the 900kg prototype can exceed 180mph, slotting nicely between GT and LMP1 in multiclass racing. Downforce levels similar to its LMP1 sibling yield exceptional cornering ability, even if mildly limited by an off-the-shelf tire compound.
