Robert Liang, 63, knew the German automaker was cheating and worked to cover it up, US District Court Judge Sean Cox said during the sentencing hearing in Detroit. The judge imposed a 40-month prison sentence.
"The conspiracy perpetrated a massive ... And stunning fraud on the American consumer that attacked and destroyed the very foundation of our economic system," Cox said.
Liang, who faces deportation to Germany upon his release from prison, declined to speak on his own behalf Friday. Prosecutors had requested a 36-month prison term and a $20,000 fine.
"What occurred here was wrong," defense attorney Daniel Nixon said. "But he wasn't the mastermind. He was not motivated by greed."
