02Overview
What Michigan International Speedway is like to drive.
The full circuit layout at Michigan International Speedway is 3.52 miles with 14 corners worth setting up for and about 50 ft of elevation change. A generic track-day car in our model brakes hard 9 times a lap and is at full throttle for about 56% of the distance; the longest straight runs roughly 2444 ft.
2 of the corners are slow (under 50 mph in the model), 6 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. Some apexes sit on crests, where the car goes light. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Michigan International Speedway later.

The speed trace is a model, not a real lap: a generic track-day car (about 1.1 g of cornering grip, 1 g braking, 150 W/kg) driven on the computed line through an assumed 12 m wide track. Use it to see where the braking zones and flat-out sections are, not to predict your speeds. Elevation: USGS 3DEP 1/3 arc-second (NED 10 m) via OpenTopoData, sampled every 25 m along the mapped centerline.
04Corner by corner
The corners at Michigan International Speedway.
TRACK’s own corner numbering (C1, C2…), found from the curvature of the mapped centerline. It isn’t the official turn numbering. Each diagram shows the computed line: the minimum-curvature path through an assumed 12 m wide track. It’s a geometric starting point. Your instructor’s line comes first.

Fast left-hander
↰ LeftfastkinkTRACK numbering
A fast left-hand kink that turns about 20°, tightening to a radius of roughly 73 m (240 ft). The model car brakes for about 155 m (509 ft), from 149 to 122 mph. The computed line turns in from the right side, takes an early apex, about 5 m before the geometric apex, and lets the car run out to the right on exit.

06Time it with TRACK
Drive Michigan International Speedway. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Michigan International Speedway and the layout from your GPS trace, then times every lap and sector with a live delta to your best.
- 1DetectTRACK matches your first few hundred metres against every mapped layout at Michigan International Speedway, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is mapped · unverified. When you’re stopped, TRACK shows it on the map: accept it or tap to move it. You’re never asked while driving.
- 3Laps, timed retroactivelyLaps you drove before confirming are timed from the recorded trace, so you don’t lose your first session.
- 4Go furtherSync a GoPro for video with telemetry and let TRACK Engineer point out where the time is. External 10–25 Hz GPS receivers for tighter sectors are awaiting hardware validation.

FAQ
Michigan International Speedway, answered.
How long is Michigan International Speedway?
OpenStreetMap maps 6 closed loops at Michigan International Speedway, from 2.42 mi to 3.52 mi (5.67 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.
How much elevation change is there at Michigan International Speedway?
About 50 ft (15 m) between the lowest and highest points of the full circuit layout, from USGS 3DEP elevation data sampled every 25 m. The steepest stretch is around 6%.
Which direction does Michigan International Speedway run?
The main mapped layout runs counter-clockwise, from one-way tagging in OpenStreetMap. Check the event’s driver briefing: some venues run reverse-direction days.
Can I time laps at Michigan International Speedway with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Michigan International Speedway and the layout you’re driving from GPS, then times laps and sectors. A phone’s GPS is good for lap times; an external 10–25 Hz receiver tightens sector splits.
Where is the start/finish line at Michigan International Speedway?
The line TRACK uses comes from a start/finish point placed in OpenStreetMap. It isn’t verified on site, so the app asks you to confirm or move it before timing your first session here.
How do I find track days at Michigan International Speedway?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar (also linked) lists its events too. TRACK doesn’t list events itself.
Where can I stay near Michigan International Speedway?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Michigan International Speedway from OpenStreetMap, with straight-line distances. Book early for big event weekends.
