Volkswagen dieselgate: Outrage over monkey and human tests

German carmakers are scrambling to explain why toxic exhaust tests were performed on monkeys and humans, but it is another public relations disaster with the ‘dieselgate’ scandal still in the minds of the public.

German politicians are demanding to know why well-known carmakers funded research into secret tests on toxic exhaust fumes.

BMW, Daimler and Volkswagen have been implicated in the scandal after a research group did tests on monkeys and humans.
