Cadillac has announced it will no longer offer the CT6 with a plug-in hybrid powertrain in North America, due to slow sales and, possibly, the current trade war between the U.S. and China.

The CT6 PHEV is produced in China largely for the Chinese market, and it will still be produced there, but Cadillac will no longer import those cars to the US, which could be due to tariffs placed on goods coming from China.

GM says it’s focused on building a performance V-Series CT6, GM Authority reports, and that “Cadillac remains committed to electrified systems for our vehicles.”

“Although production of the CT6 Plug-In for North America is discontinuing for the 2019 model year, alternative fuel vehicles remain a part of our future product portfolio,” a rep said.

It’s possible the PHEV was too much of a niche vehicle for buyers to wrap their heads around, and that it was not without its faults. The trunk space was significantly reduced due to the batteries in the trunk, and it cost almost $87,000 in Canada.

Despite a few drawbacks, the Cadillac delivered an estimated 3.6 L/100km and a range of 643 kilometres. About 50 of those kilometres could be covered on pure electric power alone.
