Volkswagen Dieselgate

This is a research-stage projection. It is not admitted. Source attribution does not establish independent corroboration. Inspect

Research dossier, timeline and source context. The original research material remains available for inspection.

Volkswagen Group's use in U.S.-market diesel vehicles of software/calibrations that caused emissions controls to perform differently during regulatory testing than during normal driving; the independent real-world testing that surfaced the discrepancy; EPA/CARB Notices of Violation and recall/remedy proceedings; Volkswagen AG's U.S. criminal guilty plea; individual criminal proceedings; U.S. Clean Air Act and consumer settlements; and scientific efforts to estimate excess NOx and health consequences.

Scope

The U.S. corpus is the first governed demo scope because it contains unusually strong adjudicative and regulatory records. Global EA189 vehicle counts and Volkswagen's current first-party legal position are included only where needed to demonstrate scope/knowledge distinctions.

This dossier is not:

a full history of diesel emissions regulation worldwide;

a claim that U.S. law and European law define defeat devices identically;

a final adjudication of every Volkswagen executive's knowledge;

an assertion that every affected vehicle emitted the same multiple of the standard;

a claim that modelled premature deaths are individually identifiable victims.

Temporal bounds

Discovery/testing: 2013–2015 U.S. regulatory/enforcement peak: 2015–2017 Remedy/consumer program: 2016–2020+ Current corporate/legal reporting: through 2026

Not established on this record

Boundary

"Volkswagen cheated emissions tests" is strongly settled in the U.S. record, but "every diesel Volkswagen cheated" is false at that scope.

semantic trap / refusal

Boundary

The September 2015 U.S. NOV covered 2.0L model-year 2009–2015 vehicles; the later 3.0L matter had a different vehicle/model-year scope and a different emissions multiplier.

semantic trap / refusal

Boundary

"Up to 40 times" is not the measured emission rate of every affected vehicle under every normal driving condition.

semantic trap / refusal

Boundary

WVU's 2014 study tested three vehicles; it did not itself prove a fleetwide intentional defeat-device scheme.

semantic trap / refusal

Boundary

Lab-vs-road discrepancy ≠ proof of deliberate cheating without the additional software/regulatory evidence.

semantic trap / refusal

Boundary

EPA's September 2015 NOV is an allegation/enforcement notice. Volkswagen's later corporate guilty plea is a materially stronger adjudicative object.

semantic trap / refusal

Boundary

A corporate guilty plea does not establish that every board member or executive knew of the scheme throughout the same period.

semantic trap / refusal

Boundary

An indictment of an executive is not a conviction.

semantic trap / refusal

Boundary

James Liang's and Oliver Schmidt's guilty pleas are individual-specific; they do not define the knowledge of every employee or board member.

semantic trap / refusal

Boundary

Volkswagen's current annual-report statement about Board of Management knowledge is a first-party legal position, not an independent adjudication.

semantic trap / refusal

Boundary

Approximately 590,000 affected U.S. vehicles ≠ roughly 11 million EA189 vehicles worldwide.

semantic trap / refusal

Boundary

The initial September 2015 U.S. count for the 2.0L matter ≠ the later combined U.S. 2.0L + 3.0L count.

semantic trap / refusal

Boundary

Consumer compensation dollars ≠ environmental mitigation dollars ≠ criminal penalty ≠ civil penalty.

semantic trap / refusal

Boundary

A buyback/remedy settlement is not a measure of public-health damage.

semantic trap / refusal

Boundary

A $2.7B mitigation trust was designed to mitigate excess NOx; that amount is not a direct monetized estimate of deaths or disease.

semantic trap / refusal

Boundary

A peer-reviewed estimate of premature mortality is model-dependent.

semantic trap / refusal

Boundary

NOx emissions are not the same variable as NO2 exposure, ozone, PM2.5, hospital admissions, or deaths.

semantic trap / refusal

Boundary

An approved emissions modification changes the safety/compliance-relevant configuration of a subject vehicle.

semantic trap / refusal

Boundary

"Clean Diesel" advertising claims and Clean Air Act certification violations are related but legally distinct consumer/environmental claims.

semantic trap / refusal

Boundary

Court-approved consent decrees retain settlement posture; they do not automatically convert every original civil complaint allegation into a trial finding.

semantic trap / refusal
