The Federal Motor Vehicle Safety Standard in question is Number 214, and the Feds will not yield:
FMVSS No. 214 incorporates a new test that replicates the scenario where a car slides sideways into a tree or pole. Finalized in 2007, the test began being phased in to new cars starting in 2010, but automakers that produce fewer than 5,000 units have been exempt from the phase-in period. That is until September 1, 2014 when all vehicles (excluding convertibles) are expected to be compliant; convertible have until September 1, 2015.
According to the petition [by several US Aston Martin dealers], the coupe and convertible models of the DB9 and Vantage will not meet this regulation within that timeframe, and claims that Aston Martin would require an investment of $30 million (€22.4 million) to make the necessary changes to the vehicles, which the petition says that automaker doesn’t have. Even worse, the next-generation models of both cars have been delayed with no specific time table for their arrival.
Feds: “Drop dead”:
ICYMI: Any DB9 or Vantage built after Monday (Sept 1) is not allowed to be sold in the U.S.

So that would seem to be that. Formal statements are expected shortly.
