EPA Releases Cadillac CT6 PHV Range and Efficiency Ratings

The U.S. Environmental Protection Agency has released further details on the Cadillac CT6 PHV.

After bringing over the CT6 PHV over from China in late March, Cadillac received an initial 31 mile battery-only estimate. That’s been broken out by EPA to 27.76 miles city, 33.94 miles on a highway, and 31 miles in combined battery-powered range.

That’s not bad for a large, heavy sedan though it’s officially classified by interior volume as a midsize car.

Its overall MPGe rating could be better however, being 62 in miles per gallon equivalent (MPGe).

For the gasoline engine, the EPA gave a rating of 23 city, 29 highway, and 26 combined mpg.

By comparison, Cadillac’s sister brand Chevrolet earned a 106 MPGe rating for its 2017 Volt. It is rated 53 miles battery only and 42 mpg combined for its regular gas engine.

Of course, the Volt is a smaller and lighter car running off a 1.5 liter four-cylinder engine versus the Cadillac CT6 PHV and its 2.0 liter four-cylinder engine.

General Motors worked on improving that rating from original 2011 Volt. That version had 93 MPGe with 35 miles electric and 37 combined mpg.

For now, the exported-from-China Cadillac will be in limited supply in the U.S.

Retail pricing starts at $75,095 with $995 destination charge. So far, the federal government hasn’t released a federal tax credit for the CT6 PHV.

The Cadillac ELR plug-in hybrid, which went out of production last year, had a $7,500 federal tax credit. The 2017 Chevy Volt also gets a $7,500 credit.
