Data notes (1)
- Length check failed — 1483 m computed vs 2820 m published (-47.4%, Wikidata Q2630372). No mapped loop matches the published length (it may describe a layout OSM does not map as a closed loop, or a historic layout).

02Overview
What Top Gear test track is like to drive.
The full circuit layout at Top Gear test track is 0.92 miles with 5 corners worth setting up for. A generic track-day car in our model brakes hard 3 times a lap and is at full throttle for about 44% of the distance; the longest straight runs roughly 1214 ft.
1 of the corners are slow (under 50 mph in the model), 2 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Top Gear test track 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 data for this track isn’t loaded yet.
04Corner by corner
The corners at Top Gear test track.
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.
- C1
Bacharach
↰ LeftmediumcornerTRACK numbering
A medium left-hand corner that turns about 87°, tightening to a radius of roughly 42 m (138 ft). The model car brakes for about 155 m (509 ft), from 117 to 65 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.

Gambon
↰ LeftslowcornerTRACK numbering
A slow left-hand corner that turns about 90°, tightening to a radius of roughly 22 m (72 ft). The model car brakes for about 70 m (230 ft), from 79 to 47 mph. The computed line turns in from the right side, takes an apex close to the geometric apex, and lets the car run out to the right on exit.

↰ LeftmediumhairpinTRACK numbering
A medium left-hand hairpin that turns about 158°, tightening to a radius of roughly 23 m (75 ft). The model car brakes for about 185 m (607 ft), from 118 to 52 mph. The computed line turns in from the right side, takes an apex close to the geometric apex, and lets the car run out to the right on exit.

Chicago
↱ RightfastchicaneTRACK numbering
A fast right-hand chicane that turns about 57°, tightening to a radius of roughly 41 m (135 ft). The model car barely brakes here, carrying about 87 mph: a lift or a confident throttle balance. The computed line turns in from the left side, takes an early apex, about 20 m before the geometric apex, and lets the car run out to the left on exit.

05Configurations
Every mapped loop at Top Gear test track.
TRACK finds each closed loop in the OpenStreetMap raceway network. Named layouts come from OSM circuit relations; the rest are named by length, and some may be combinations the venue never runs. Your first session confirms which one you drove.

06Time it with TRACK
Drive Top Gear test track. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Top Gear test track 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 Top Gear test track, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is estimated. 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.
- Venue and layout detection is tested on simulated drives over real OpenStreetMap circuits, not yet in a real car. Compatible GPS receivers

FAQ
Top Gear test track, answered.
How long is Top Gear test track?
OpenStreetMap maps 2 closed loops at Top Gear test track, from 0.86 mi to 0.92 mi (1.48 km). These are mapped centerline lengths; the venue’s published figures can differ slightly. The published length we cross-check against is 1.75 mi.
Which direction does Top Gear test track run?
OpenStreetMap doesn’t record a direction for the main layout at Top Gear test track. Venues sometimes run both ways. TRACK takes the direction from your first laps.
Can I time laps at Top Gear test track with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Top Gear test track 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 Top Gear test track?
TRACK estimates the line from the mapped geometry (usually beside the pit lane, or on the longest straight). 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 Top Gear test track?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar lists its events too. TRACK doesn’t list events itself.
Where can I stay near Top Gear test track?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Top Gear test track from OpenStreetMap, with straight-line distances. Book early for big event weekends.

TRACK is not affiliated with or endorsed by Top Gear test track, MotorsportReg or any business listed here. The venue name identifies the location only and belongs to its owner. TRACK shows no lap records or official results for this venue. Driving advice is general: your instructor, the event’s rules and the venue’s rules come first.
