The US Environmental Protection Agency just released its official fuel-economy figures for Cadillac’s all-new CT6 plug-in hybrid sedan, giving the hefty, full-size luxury car a rating of 26 miles-per-gallon on the combined test cycle. That figure results from a city rating of 23 mpg, and a highway rating of 29.
Those figures aren’t as swell as many would have hoped. After all, the Cadillac CT6 with just a turbocharged 2.0L Ecotec LTG is rated at 25 mpg combined, with 22 mpg in the city and 30 on the highway.
However, the EPA also rated the CT6 PHEV’s electric-only range, observing a 28-mile range in the city, and a 34-mile range on the highway, for a combined battery range of 31 miles. Since that’s more than enough range to cover most everyday commutes, it’s conceivable that owners will still see a sizable improvement with regard to fueling costs.
The EPA’s MPGe (Miles-Per-Gallon equivalent) rating for the 2017 Cadillac CT6 PHEV is 62.
The all-new Cadillac CT6 PHEV is built at General Motors’ Cadillac plant in Jinqiao, China, and began arriving at dealers last month. It starts at $76,090 US including destination, before government credits.

How can you have 26 mpg if the car drives 31 miles on electric charge? Those numbers don't match up!
I wish the EPA would find a strip of highway and fill the car full of fuel and drive until it runs out of gas. Bring along a chase vehicle with extra fuel. Then calculate the mpg's for highway. Then do the same for city.
At least it would be real world driving numbers as apposed to just putting a car on a machine for the test.
Misleading headline. The 26 MPG rating of the gas engine isn't the important figure here. This is a PHEV. The important number is 62 MPGe. Compare that to the competition and you can make the case that this is actually an impressive car. Looking at 530e, 740e, and S550e, the CT6 PHEV is cheaper, has more range, comparable MPGe, and comparable acceleration.
Then this 62 mpg should be what's posted
This article doesn't make any sense given that the CT6 has a battery range of 28 miles or that the non-PHEV CT6 has the same combined mileage as the PHEV; the only reason why this would happen is that there was something wrong possibly with the PHEV's battery and the CT6 PHEV never went on battery mode ever during the test.
Sounds like they seperated the MPG (26 combined) gas only. from the MPGE 62 electric only ... what everyone wants to know is what is the MPG and MPGE combined number.
