A bunch of the other automakers had similar 'defeat devices', and they're called out on the Wikipedia page.
Earlier, Feb 2018, German newspaper Bild am Sonntag reported that US authorities
investigating Mercedes have discovered that its vehicles are equipped with illegal
software to help them pass United States' stringent emission tests. The claimed
defeat devices include a Bit 15 mode to switch off emissions control after 16 miles
of driving (the length of an official U.S. emissions test), and Slipguard which tries
to directly determine if the car is being tested based on speed and acceleration
profiles.
