The Parabolica is a constant-radius right-hander that opens onto the start–finish straight. Entry speed is approximately 320 km/h after braking from the Variante Ascari complex; minimum speed at the apex is approximately 235 km/h; exit speed back onto the straight rises through 280 km/h as the cars begin to accelerate for the 1.1 km pit straight. The corner has no significant elevation change, but its radius is sufficiently constant that the entire seven seconds of corner duration are spent at near-maximum lateral g-load, with the cars on the edge of tyre grip in the closing third.
The name Parabolica derives from the Italian for "parabolic curve" — the corner's geometry, viewed from above, is an approximate parabola rather than a constant-radius arc. (The corner is genuinely closer to a parabolic shape than to a circle: it opens out as it approaches the pit straight, allowing earlier throttle application.)
The corner was constructed in its current form in 1955 as part of the major Monza reconfiguration that abandoned the high-speed banked oval section after the 1955 Monza accident in which two cars left the banking. The corner was unnamed in early period; "Parabolica" entered common usage in Italian motoring journalism through the late 1950s and was formalised by the Automobile Club d'Italia in 1972.
In 2021, on the 20th anniversary of Michele Alboreto's death in a testing accident at Lausitzring, the Automobile Club d'Italia and the city of Monza renamed the corner the Curva Alboreto as a permanent tribute. Alboreto was a Milanese driver, Ferrari's lead from 1984 to 1988, runner-up in the 1985 World Championship, and the most-loved Italian F1 driver of his generation. The renaming is recognised on circuit signage and in formal communications, though "Parabolica" remains in common use among drivers, fans and broadcasters.
1961 — Wolfgang von Trips and Jim Clark collided on the entry to the Parabolica in the Italian Grand Prix. Von Trips's Ferrari was launched into the spectator area; 15 spectators were killed in addition to Von Trips. The accident is one of the deadliest in F1 history.
1970 — Jochen Rindt was killed in qualifying for the Italian Grand Prix when his Lotus 72 broke a brake shaft on the approach to the Parabolica. The crash car submarined under the Armco; Rindt was posthumously awarded the 1970 World Championship.
2000 — A heavy multi-car pile-up occurred on the run-in to the Parabolica, killing trackside marshal Paolo Gislimberti. The barriers were reinforced as a consequence.
The Parabolica's most significant modification was a 2014 reduction of the gravel run-off on the outside of the corner, replaced with paved tarmac in a controversial decision. Drivers who had previously been penalised for running wide on entry could now do so without consequence — a decision that critics argued reduced the corner's defining penalty profile. Some of the gravel was reinstated in subsequent off-seasons; the current state of the run-off is a mixed paved-and-gravel compromise.
At Monza, the corner has a unique property in qualifying: it precedes the longest straight on the F1 calendar. A poor exit from the Parabolica costs significant slipstreaming benefit on the run to Curva Grande the following lap. In qualifying sessions where teams have used "slipstream trains" — multiple drivers from the same team running closely to gain tow-effects — the Parabolica becomes the corner where the tow is established or lost.
The Parabolica is in every Monza sim. Assetto Corsa's ks_monza includes the 2018-current configuration with the post-2014 run-off; AMS2's Monza_2020 is the modern layout; ACC's monza is the GT3-era configuration; iRacing's monza/gp reflects the current track surface and run-off state; LMU's monza has the 2024 WEC configuration.
