Corner Exit Prioritization
Sacrificing entry speed for exit speed on corners followed by straights.
Corner exit prioritization is a driving philosophy where getting maximum speed out of a corner — especially onto a long straight — is valued more highly than entering the corner at top speed. In Formula 1, the speed carried onto a straight multiplies over the entire straight length, making a strong exit worth far more than a fast entry. Understanding this concept helps you see why the best drivers sometimes seem to 'slow down to go fast' and why certain corners disproportionately affect lap time.
Key Ideas
Exit Speed Multiplies Over Distance
A small speed advantage at corner exit — even 2-3 km/h — compounds over the entire following straight. If a straight is 800 meters long, that small exit speed difference can translate to a significant time gain. This is why exits onto long straights are the highest-priority corners on any circuit.
Sacrificing Entry for Exit
To maximize exit speed, drivers often take a wider entry line, turning in later and prioritizing getting the car straight and on the throttle early. This might mean entering the corner slightly slower, but the earlier throttle application more than compensates on the following straight.
Identifying Key Corners
Not all corners are equal. Engineers and drivers analyze each corner's 'time sensitivity' — how much a change in cornering speed affects overall lap time. Corners before long straights are almost always the most time-sensitive, and drivers prioritize these above all others.
Throttle Application Point
The critical moment in corner exit is when the driver begins applying full throttle. The earlier they can go to full throttle — because the car is pointing straight enough — the faster they will be down the following straight. The whole corner technique builds toward this moment.
Traction and Rear Grip
Getting maximum exit speed requires excellent rear traction. If the rear tires are overheating, the driver can't apply full throttle early without wheelspin or sliding. This is why rear tire condition is so critical at circuits with important corner exits.

See the Why
On GPS-overlay replays, compare two drivers through a corner followed by a long straight. The faster overall driver often enters the corner at similar or even slower speed, but gets on the throttle earlier and exits faster. By the end of the straight, they are significantly ahead. This pattern repeats at every key corner exit, and the cumulative effect determines lap time.
Real-World Examples
Wide Entry, Fast Exit
A driver takes a wider entry line into the final corner before the main straight, turning in later than might seem optimal. This allows them to straighten the car earlier, apply full throttle sooner, and carry an extra 5 km/h onto the straight. Over the 1-kilometer straight, this translates to a two-tenth time gain.
Traction-Limited Exit
Late in a stint, a driver's rear tires are degraded. They can no longer apply full throttle at their usual point on corner exit without the rear sliding. They must wait longer to go to full power, costing them straight-line speed. This traction limitation explains their increasing lap times.
Compromising a Less Important Corner
At a circuit with two consecutive corners — the first before a short straight, the second before a 1.5-kilometer straight — a driver takes a suboptimal line through the first corner to set up a perfect exit from the second. They lose a hundredth in corner one but gain three tenths on the long straight.
Quick Check
Why is corner exit speed onto a long straight more valuable than corner entry speed?
Reveal answer
A small speed advantage at corner exit carries forward over the entire following straight. The longer the straight, the more that initial speed difference compounds. This is why corners before long straights are the most important ones to get right — the exit speed effect is amplified by distance.
