Wow, that's a hell lot!
I thought the record (set by Frentzen in Imola 1997) was 5.1 g...
Um, maybe I'm mistaken

2009 DATA
Image

The twisting, 14-corner layout of the Hungaroring features just one legitimate overtaking opportunity per lap, into Turn One. Apart from this straight of just over 700 metres, the circuit is filled with sequences of low to medium-speed corners, with short braking distances which make overtaking nearly impossible. The result is that the teams all run with maximum downforce levels, similar if not identical to those used in Monaco, in order to optimise not just cornering speeds, but also braking and traction. Maximum speeds achieved on the main straight rarely exceed 300 km/h with the V8 engines.

Length Km : 4.381
Number of laps: 70
Race distance Km 306.670

Number of brakings: 11
Pole 2008: – 1:20.899 Hamilton
Pole 2009: – 1:21.569 Alonso
Time spent under braking per lap: 13%
