Audi has apparently paused sales of two of their high performance models, the Audi S5 and Audi S4 whilst the company is testing out new engine management software for the cars.
According to a recent report, this new software will have to be tested by German Regulators before new cars can be sold with it, this is the reason why new orders for the cars have been paused.
“Audi has decided on a stricter interpretation of tolerances of the regulations for measuring CO2 emissions applicable in the EU,” said an Audi spokesperson. “This may lead to adjusted CO2 figures for some Audi models.”
Audi are apparently making changes to the software for both the Audi S5 and Audi S4 to “comfort and spontaneity” and “may lead to a moderate increase in fuel consumption”. As yet there are no details on when sales of these tow vehicles will resume.
