Monza 2026

f1-2026-monza-1-200The switch between two tactical tasks made it look as though someone had shut down the nuclear reactor aboard Antonelli’s starship halfway through the race. The Mercedes that had passed almost the entire field by lap 18 did not suddenly become slower once it took the lead. What changed were the conditions in which it produced its speed, and the opponent it now had to beat. Passing slower cars with the help of their slipstream is one task. Pulling away from another Mercedes, now benefiting from your slipstream, is considerably harder.

The Italian Grand Prix, also carrying the title of European Grand Prix. Formula One cars on the grid. Let's see what is being written out of racing history.

Twenty to One

btcc25-croft-1-200Croft begins not with a corner, but with the boost allocation table. During Saturday’s qualifying session and Qualifying Race, championship leader Ash Sutton will receive additional turbo boost for just one second per lap, and will only be able to activate it above 140km/h. Tom Ingram gets three seconds from 135km/h; Dan Cammish, five from 130. Gordon Shedden, eighth in the standings, and everyone below him can use the boost for 20 seconds from a threshold of 105km/h. The difference becomes even starker in Sunday’s opening race: Sutton gets one boost-enabled lap, Ingram two, Cammish three, while eighth place and below get ten. There is no misprint. The air is being measured out by the teaspoon.

Horses in the Cylinder, Half a Second in the Tunnel

f1-26-amr26-w17-200Ahead of Zandvoort, two rather different pieces of news arrived from opposite ends of the field. Honda reported that it had finally managed to stuff back into its engine some of the horsepower the RA626H had misplaced over the winter, while Mercedes explained why the car that started the season at the front has suddenly begun receiving its major upgrades later than its rivals.

Elevation Matters

btcc-at-sugo200Two circuits can look much alike by one obvious measure - and quite different from the cockpit. Two August race meetings provided a useful example: Super Formula visited Sugo, while the British Touring Car Championship went to Knockhill. Both circuits are known for their pronounced elevation changes. The figures seem to confirm the resemblance.

Talking to the Machine

f1-26-Hun-200The old racing-driver habit of talking to the car - assuming such a habit has survived our digital age at all - is gradually acquiring an entirely new meaning. The pity is that the car still does not understand the driver, while the driver is increasingly unsure that he understands the language spoken by the thing whose steering wheel he has spent years turning with relative confidence. And, more to the point, he has no idea what the thing intends to do in the next corner.

A GT300 Race Engineer’s Theoretical Setup Guide

gainer Z 2026 fuji 200We should begin with a small correction to the way the car itself is described. The GAINER Z is neither a conventional tube-frame silhouette nor a Mother Chassis (MC86). It is an original GTA-GT300 car built around the retained production passenger-cell structure of the Nissan RZ34. At the same time, its suspension, aerodynamics, powertrain installation and most of its racing hardware have either been designed specifically for GT300 or heavily adapted for it.
