Cadillac CT6 Plug-In Gets Official EPA Ratings

APR 21 2017 BY ERIC LOVEDAY 33

The All-New Cadillac CT6 PHV Arrived In The US In March. But It’s Not Nearly As Efficient As Hoped

It gets rather craptastic gas mileage, but at least it plugs in so you don’t have to burn it.

The EPA’s internal database has been updated to include the all-new Cadillac CT6 plug-in hybrid.

We’ll start first with the bright spots. The CT6 plug-in impresses us with its electric range. Here’s the breakdown:

  • City range – 27.76 miles
  • Highway range – 33.94 miles
  • Combined range – 31 miles

See below for EPA chart data with additional info such as PHEV composite MPGe, charge time and total range:

Now for the bad news. The CT6 plug-in is portly at well north of 4,000 pounds (though classified only as midsize, according to the EPA), apparently not very aerodynamic and therefore it guzzles down the premium gas.  So if you can do it, we would suggesting sticking to electricity as much as possible.

The MPG rating are as follows:

  • City MPG – 23
  • Highway MPG – 29
  • Combined MPG – 26

See details below:

Here’s some additional info via the EPA. Note the MPGe figure is officially 62, a disappointing number too.

The all-new, built-in-China, Cadillac CT6 PHV arrived in America in March. There’s limited supply at U.S. dealers right now. Pricing starts at $75,095 (+ $995 destination). Additional details on the CT6 plug-in can be found here.

But at least it’s made in China!

Gadus Womp

It just keeps getting worse and worser for GM’s attempt to bail out the Cadillac brand…think they picked the wrong man to head the division?? Manufacture the car in China and then attempt to sell it in the U.S.?, at Luxo prices?, really?

For 75K, I’ll get a Tesla
Thank you.

I would never go back to the mediocre performance of a gas car.

Taser54

If you had 75k, that is

Bacardi

This or the quicker, better MPG, AWD, 34 speaker, made in the USA and supercruise optioned ICE CT6 for the same price? Pretty easy choice…

unlucky

Huh? There’s no CT6 that gets better mpg than this one.

The next best is the 2.0T at 25mpg combined. And that isn’t AWD either, the best an AWD model gets is 21mpg combined.

Although the others do have larger gas tanks so the non-AWD model gets better range than this one.

vdiv

0-31 all-electric range? So even with a fully charged battery the CT6 may not even get a single mile on battery alone?

georgeS

@vdiv,
It’s not an EREV. Step on it and the engine comes on.

You will note there’s no 0060 times in pure electric mode.

Malevolence
Per Motor Trend, anything more than 60% accelerator pedal fires the engine (it’s unclear whether or not there’s an EV mode that can be selected to prevent it, or if you just have to be careful with your right foot). So if you’re hammering on the throttle as soon as you leave your driveway, you’ll get 0 miles, and if you drive gingerly (well, not that gingerly since you have 200 electric horsepower on tap), it should stay in EV mode for ~31 miles before switching over. I’m assuming MT’s number is just using the (oversimplified) math that 200 electric horsepower of the 335 peak combined horsepower is 60%. For comparison’s sake, that should give it slightly worse performance than a gen 1 Volt as far as all electric performance (due to the same electric horsepower with higher weight) and range (due to higher weight and poorer aerodynamics even though it’s a larger battery). By my count, the BMW i3 Rex and the Chevy Volt are the only two plug in hybrid cars on sale today that offer full (or at least within the margin of error) performance in gas only mode. I was hoping that both this and the… Read more »

Whoops, I meant electric only mode. Hit post too fast!

@ Malevolence
“well, not that gingerly since you have 200 electric horsepower on tap”

I’m wondering if they push the battery that hard.

Malevolence
On the battery side, I assume it’s basically the same setup as the 149hp gen 2 Volt (and the 157 electric-only horsepower ELR for that matter) and presumably uses pretty much the exact same pack as the gen 2 Volt, so I don’t see why not. Based on tests using packs from wrecked gen 1 cars and tear-downs, the LG cells in the Volt seem to handle about 8-10C no problem, which translates to about 200-250hp. It sounds like the CT6 is using two 100hp motors instead of one 100hp and one 50hp like is used in the Volts. So the CT6 is only hitting the cells a little harder than the Volts and ELR. They’ve all been pretty rock solid so far, so I’m guessing LG and GM are willing to push the boundaries a little further to go up to 200hp from 149/157hp in the Volts and ELR. Based on the chemistry that GM has been using so far on plug-in hybrids (who knows with the Bolt… yet) there’s no reason to think they can’t handle 200hp in the CT6! The Bolt is probably more like the Leaf and Teslas and trades off some peak discharge capability for… Read more »

I don’t think there are any other PHEVs with full performance in EV mode. The ELR had it (duh). And the 2nd gen Ford Energi’s are pretty close.

Malevolence
Thanks! That confirms what I thought. But I didn’t realize the newer Energi’s have a true anemic-but-less-anemic-than-the-Prius-Prime EV mode. That’s good info. I’ve kind of passed them over since they have such short range, but that definitely makes them more interesting. The CT6 looked like it would be a cool (but too expensive in reality) option. I did intentionally exclude the ELR on two technicalities. First, the ELR is rated at 181 horsepower in hybrid mode and only 157 in electric only. While the Volt is rated for 149 in both modes, it has been shown to get slightly quicker 0-60 times in hybrid mode; I think this can mostly be calked up to there being less voltage sag when the engine is running, and perhaps a little difference in the torque curve in hybrid mode. It seems like there has been a concerted effort by GM to maintain the same power under either mode. Perhaps this is for marketing reasons, or maybe for no other reason than minimizing the robustness of the suspension and downstream drive-line components. No matter the reason, that’s how it was made. I’d call the 17% power increase for the ELR more than a mere… Read more »

So this is the opposite of a PriPrime.
A gass hog with just 6miles more AER.

Made by a US company that chose to move the build/manufacture it in China all so they can ship it back to the US and sell.

menorman

It gets better highway miles than city even in electric mode?

2013VOLT

Agreed, at this price point a Model S is the better value. They won’t sell very many. Why they won’t build a Voltec SUV or pickup is beyond me.

Get Real

Too bad they didn’t make it aerodynamic because they probably could have got it to 40 AER if they had at least designed it to be a big ELR.

The real tragedy here is that GM continues to SQUANDER their opportunity to put this drivetrain into some SUVs and even the Silverado and build marketshare and maybe even Volt like enthusiasm for these EREV products.

I predict they will do this the minute Tesla brings out their BEV pickup and Model Y since GM leadership is apparently content to only react rather then be truly pro-active.

georgeS

get real,
Yes the CT6 power train would be perfect in a pick up….but if GM prices it sky high then it won’t sell.

MTN Ranger

How about they bring back the Cadillac pickup truck with Voltec.

Nix

Get Real:

“The real tragedy here is that GM continues to SQUANDER their opportunity to put this drivetrain into some SUVs”

Well, you might ask the guy who wrote this about what the aerodynamics of an SUV body would do to the AER:

“Too bad they didn’t make it aerodynamic because they probably could have got it to 40 AER”

I think you may have answered your own question….

Get Real

Fair point Nix, let me rephrase my original statement:

If GM put this drivetrain into some decent AERODYNAMIC SUVs they could build marketshare and maybe even some Volt-like mojo to prepare them for the upcoming Tesla Tsunami.

The problem is that these conversion vehicles always end up being compromised so that GM should be doing clean sheet designs as much as possible for their EVs.

In any case, GM is still somewhat ahead of Ford and FCA in at least the EREV tech although the Pacifica looks like a pretty excellent implementation for a big vehicle.

Spider-Dan

The next time someone says that GM is intentionally torpedoing the EV market by not putting Voltec in a crossover or SUV, remember this article.

GM didn’t invest billions in Voltec just to leave money on the table. There’s a reason why the Volt is a compact car, and it’s not because GM hates making money or wants EVs to fail.

jelloslug

Did they learn nothing from making a plug in that costs Tesla money?

Blastphemy

It’s bordering on hilarious that after making a plug-in ELR that wasn’t as good as the Volt, now Cadillac makes a plug-in CT6 that isn’t as good as the ELR!

On top of that, the CT6 PHEV can’t have the 34-speaker Bose Panaray audio system upgrade (because the batteries are in the way), will never have active-rear-steering (because the batteries are in the way), and will never have SuperCruise (because the batteries are in the way).

All Cadillac had to do was built a CT6 around the Bolt’s battery and Tesla would be quaking in its boots.

ModernMarvelFan

“All Cadillac had to do was built a CT6 around the Bolt’s battery and Tesla would be quaking in its boots”

Tesla won’t… If CT6 BEV exist, Tesla will laugh at it because it got no charging infrastructure.

Loboc

Never say never.

No GM vehicle has SuperCruise.
$15k for a radio? I’ll pass.
Rear steering? Is that really necessary?

This car is exactly what GM fans are asking for: Voltec in a bigger car.

James

This makes the Pacifica Hybrid look like the steal of the year!

James

75 kWh Model S gives you so much more for your money, it’s not fonny.

BIll Howland

To me, DeNyschen (foreign head of Cadillac) should be fired.

The closest dealership to me is 386 miles away. A tesla service center (recently built) is 220 miles away. Through Canada it is still 250 miles away, in Clinton Township, Michigan. I called them and they won’t have ANY CT6 PHEV’s until the END OF THE YEAR.

This is a joke.

pjwood1

I don’t think there were enough focus groups, on how important all-electric modality is in these things.

Whoda thunk? Shrink the engine, not the battery. We’ll get there.

Cadillac CT6 is a full size sedan at a length of 202 inches which puts it in the same league as Benz S Series, BMW 7 Series. Its wrongly quoted as mid size sedan. Only CTS is the mid size and no idea as who named like this with the first 2 letters the same.

With a 31 mile range and a $75,000 price tag the CT6 plugin is much better than the
Benz S Series plugin with a $95,000 price tag for a 10 mile range
BMW 7 Series plugin with a $90,000 price tag for a 15 mile range

All this is only for someone who does frequent long distance trips with short breaks.
Otherwise, just go for the Model-S 75 KWH which comes at $5,000 lesser and has a facility to seat 7 with a much faster pick up and a much smoother drive.
