Pre-season baseline — new PU manufacturer, biggest improver but still off pace

Audi 'would win the award for biggest improver across testing' (The Race ranking), with a dramatically different car after a major upgrade and significantly better poise by the end. New PU and gearbox manufacturer — teething issues expected. Fastest time 1:33.755 (+1.763s). However, Audi pushed 341 km/h at Bahrain speed trap (PlanetF1) and Hulkenberg hit 311.5 km/h at Melbourne (2nd fastest), hence straightLineSpeed rated above average at 5.5 as the team's clear strength. 714 total laps across testing — low but improving. 'Just off the rear of the main midfield group' (The Race). Bortoleto P10 at Melbourne (offset +0.1, effective 4.6) is a reasonable result for this car level. Audi co-signed the joint letter to the FIA protesting Mercedes' compression ratio loophole alongside Ferrari and Honda.

Round 1 baseline — race pace revelation, first-ever Audi F1 points (Bortoleto P9)

Biggest positive surprise. Bortoleto P9 scored first-ever Audi F1 points. Race pace median 84.470 (+0.972) — 5th fastest, ahead of Racing Bulls, Haas, and rest. Hulkenberg 311.5 km/h quali speed trap (2nd fastest). Bortoleto P10 in Q2. tyreDegradation improved: avg deg -0.0617, consistent across 3 stints. reliability drops: Hulkenberg DNS (unresolved technical failure), Bortoleto pit technical issue in quali.

Round 2 — strong race pace from Hulkenberg, reliability nightmare continues

Mixed weekend. Hulkenberg showed genuinely competitive race pace (1.173s off Mercedes, best of midfield) but a 16s pit stop and Bortoleto's DNS continue the reliability crisis — 2nd DNS in 2 rounds, plus double engine change before the weekend. New nose and front wing upgrade provides small aero gain. Race pace data should be treated cautiously — single car with near-zero degradation suggests limited clean-lap sample.

Round 3 — worst non-Cadillac degradation, Bortoleto P9 in quali but lost in race

Bortoleto qualified P9 (impressive) but deployment issues at start and wrong SC strategy dropped him to P13. Hulkenberg P11, just outside points. Worst non-Cadillac tyre degradation (-0.0655). Race pace +1.571s. Bortoleto precautionary gearbox change in FP2 continues reliability pattern. Both cars finished — first time in 2026. Sources: Formula1.com, The Race, FastF1 data.

Round 6 (Miami) — systemic reliability collapse: 5 distinct failures including engine fire DNS, intake-pressure DSQ, race DNF

Catastrophic reliability weekend confirms systemic Audi PU programme issues. (1) HUL sprint DNS — engine fire pre-race start (pu-failure). (2) BOR sprint DSQ — intake pressure exceeded maximum allowable, a PU compliance breach (pu-failure / technical). (3) HUL race DNF L7 — front-wing damage at T1 + subsequent technical issue (mechanical-failure with damage-sustained component). Brake fire in Q1, precautionary gearbox change earlier. Pattern history: R1 HUL DNS, R2 BOR DNS + double engine change, R3 BOR FP2 gearbox precaution → pattern flag. Now 5+ distinct failures across 4 rounds in both cars — meets the model's 'systemic' threshold (decay rule specifies -1.0+ cumulative). Reliability moves from 3.7 to 3.0 (-0.7); cumulative from pre-season baseline 4.5 = -1.5. Major upgrades deferred to Montreal so only 2 minor parts deployed (front brake duct + floor edge).

Round 7 (Canada) — 4-part upgrade, BOR quali speed trap leader, first clean race weekend

Audi (Sauber) deployed 4 parts (front corner, floor diffuser winglet, cooling louvres, rear corner). HUL P12, BOR P13 (both 2 laps down, no points). Both started on inters at the damp race start, forced into early pit stops. No race DNFs or DSQs — first clean Audi race of 2026 (R1 HAD DNS, R2 BOR DNS, R3 ×2 gearbox FP2, R6 ×3 incidents). BOR led the qualifying speed trap at 329.4 km/h — straightLineSpeed +0.1 in acknowledgment (smaller than the headline because qualifying traps include DRS/low-fuel effects). Reliability +0.1 (3.0 → 3.1) — small upward acknowledgment of the clean weekend; systemic pattern flag still active.

Round 9 (Barcelona) - first-ever ADUO PU (upgraded ICE + turbo) deployed on both cars; freak rock-strike DNF (no fault); launch weakness persists

traction -0.1: persistent launch/turbo-lag weakness ('big Audi turbo = bad start' - Bortoleto lost places at the start again, driveability issues all weekend per The Race). UPGRADE DOCUMENTED: first-ever use of the ADUO engine catch-up allowance - upgraded ICE + turbo on both cars, driveability-focused (Motorsport.com); no rating credit until results show. Reliability UNCHANGED by incidents (+0.2 is grid re-center only): HUL L29 was a rock from Lawson's car hitting the kill switch (freak, multi-source confirmed) and BOR carried heavy lap-1 floor damage - both damage-sustained, systemic PU thread NOT escalated. Team race-pace median discounted (BOR damaged, HUL out early). Grid reliability re-center +0.2 applied to all 11 teams (incident penalties pushed the grid reliability average to 4.33, breaching the +/-0.5 band; re-centered to 4.53, relative gaps preserved). Pipeline re-derives qualiPace/racePace from committed raw round-09; no manual pace override (dry, representative weekend). Sources: FastF1 round-09; Motorsport.com; RaceFans; The Race.

Round 10 (Austria) - 7-part package consolidates head of the non-RB midfield; best race deg in the field

BOR Q12/P11, HUL Q14/P12 - just outside the points, clearly ahead of Alpine/Haas. peakDownforce +0.2: second-biggest package on the grid (front wing endplate, floor, rear suspension, beam wing, rear wing, front/rear corners) deployed and position consolidated; moderate confidence (no before/after delta published). tyreDegradation +0.2: best race deg in the entire field (0.0330 team avg; HUL final stint 0.0026) in extreme heat, on top of solid R9 tyre life. ADUO-allowance ICE + turbo (introduced R9) had its first clean weekend. Overall +0.2 on two consecutive strong weekends (Barcelona actual P5 weekend, Austria midfield-best behind Racing Bulls). Reliability: fourth consecutive round without a rating-affecting fault (R9 rock strike ruled non-fault); no recovery credit under the decay model; systemic flag retained; +0.2 is the grid re-center only. Grid reliability re-center +0.2 applied to all 11 teams (R10 incident penalties pushed the grid reliability average to 4.36, breaching the +/-0.5 band; re-centered to 4.56, relative gaps preserved). Pipeline re-derives qualiPace/racePace from committed raw round-10; no manual pace override (dry, representative weekend). Sources: FastF1 round-10; F1.com; Motorsport.com.

Round 11 (Silverstone) - BOR P8 points, but HUL gearbox failure adds a new reliability subsystem

BOR P8 - first points since Melbourne via a well-executed undercut (held behind the Racing Bulls); race median 6th (+1.595); HUL P9 in the SQ trap (317 km/h). Reliability -0.3 pre-re-center: HUL gearbox-to-neutral failure approaching the pit entry, stopped on track lap 36 (triggered the second VSC) - explicitly not PU-related per the driver, so the PU-programme systemic thread is NOT extended; first gearbox failure of the season -> first-failure cap, new-subsystem monitoring flag; net -0.2 after re-center. HUL 5s sprint track-limits penalty - driver error. No upgrades registered; pace consistent with current DNA - no other moves. Grid reliability re-center +0.1 applied to all 11 teams (R11 incident penalties pushed the grid reliability average to 4.45, breaching the +/-0.5 band; re-centered to 4.55, relative gaps preserved).
