faster chicane. Work was planned for to be completed by 2017 in hopes of a renewed contract for Formula 1. Gravel would have also returned to the run-off area at the Parabolica bend. However, plans for the track's change were suspended due to the track being in the historic Monza Park. A lap of the circuit in a Formula One car Monza, throughout its long and storied history has been known for its high-speed, simplistic (compared to "harder" circuits such as Singapore or Monaco, which are tight, unforgiving street circuits with lots of corners) nature thanks to its 1920s design and the few alterations it has received, and is currently the fastest track on the Formula One calendar and has been so since 1991. Monza consists of very long straights and tight chicanes, putting a premium on good braking stability and traction. The circuit is very hard on engines; Formula 1 engines are at full throttle for nearly 80% of the lap, with engine failures common, notably Fernando Alonso in the 2006 Italian Grand Prix or Nico Rosberg in the 2015 Italian Grand Prix. Drivers are on full throttle for most of the lap due to its long straights and fast corners, and is usually the scenario in which the open-wheeled Formula One cars show the raw speed of which they are capable: during the mid-2000s V10 engine formula, although in 2012 with the 2.4L V8 engines, top speeds in Formula One rarely reached over ; the 1.6L turbocharged hybrid V6 engine, reduced-downforce formula of 2014 displayed top speeds of up to . The circuit is generally flat, but has a gradual gradient from the second Lesmos to the Variante Ascari. Due to the low aerodynamic profile needed, with its resulting low downforce, the grip is very low; understeer is a more serious issue than at other circuits; however, the opposite effect, oversteer, is also present in the second sector, requiring the use of a very distinctive opposite lock technique. Since both maximum power and minimal drag are keys for speed on the straights, only competitors with enough power or aerodynamic efficiency at their disposal are able to challenge for the top places. Formula One cars are set up with one of the smallest wing angles on the F1 calendar to ensure the lowest level of drag on the straights. There are only 6 corner complexes at Monza: the first
