2020 Cadillac CT4-V Is Larger Outside, Smaller Inside Than ATS

Automakers typically introduce the standard model before rolling out performance variants, but Cadillac eschewed that tradition when they unveiled the CT4-V.

The standard model will be introduced in about a month, but we have a pretty good idea of what to expect.

Despite suggestions that the car would be smaller than the ATS, this isn’t the case. The CT4-V measures 187.2 inches (4756 mm) long, 71.5 inches (1815 mm) wide and 56 inches (1423 mm) tall with a wheelbase that spans 109.3 inches (2775 mm). This means the CT4-V is 4.4 inches (112 mm) longer, 0.4 inches (10 mm) wider and 0.1 inches (3 mm) taller than the ATS sedan.

Considering the wheelbase hasn’t changed, it’s not surprising to learn the CT4-V has about the same interior space as the ATS. Front seat occupants have 42.2 inches (1078 mm) of legroom and 38.4 inches (974 mm) of headroom. This means they lose 0.3 inches (8 mm) of legroom, but gain 0.2 inches (5 mm) of headroom.

The ATS’ back seat was often criticized for being cramped and those complaints will likely continue in the CT4. Legroom drops from 33.5 inches (851 mm) to 33.4 inches (848 mm), while headroom falls from 36.8 inches (935 mm) to 36.5 inches (928 mm).

The CT4 continues to ride on the rear-wheel drive Alpha platform and the CT4-V tips the scales at approximately 3616 lbs (1640 kg). That means the car weighs 243 lbs (110 kg) more than the ATS with the turbocharged 2.0-liter four-cylinder engine and 155 lbs (70 kg) more than the model equipped the 3.6-liter V6. However, we can expect the standard CT4 to be lighter than the CT4-V.

The old 3.6-liter V6 is interesting to mention as it produced 335 hp (250 kW / 340 PS). This is 15 hp (11 kW / 15 PS) more than the turbocharged 2.7-liter four-cylinder in the CT4-V, but the new engine produces 369 lb-ft (500 Nm) of torque which is a significant increase over the V6’s 285 lb-ft (386 Nm).

As for styling, the CT4 should closely echo the CT4-V. However, we can expect a less aggressive front fascia and a revised grille. The standard model will also drop the four-tailpipe exhaust system and V-spec rear spoiler.

    So if CT5 gonna have price a little above C class, then CT4 should have price around A class sedan. In such conditions they should sell well… or not : p

    • donald seymour

      A lot of people forget this. Their sized above their competition.

  • Nordschleife

    It CAN’T POSSIBLY be smaller inside than the ATS. This car would HONESTLY be Dead On Arrival.

    • MarketAndChurch

      The rear seats will probably be like the one in the mustang. For small children or people with no legs.

    • Cobrajet

      Thicker leather.

  • Tinky-Winky

    It feels like Cadillac is having identity crisis.

    • dumblikeyou2

      This isn’t Cadillac, this is Chinallac.

  • matrem

    So they didn’t fix any of the things buyers complained about, while ruining the things buyers praised. And will probably charge similar money. Make this a China-only brand, since it’s clear GM won’t spend the time listening to what the US market wants from Cadillac (Uber luxury).

    • MarketAndChurch

      But China prefers long wheelbase models with large rear seat space. Even on c class or glc.

    • Merc1



  • ErnieB

    On a positive note, it has real exhaust pipes…

  • MarketAndChurch

    It looks pretty nice but the interior is a major let down, might have worked better as a two door two seater like the 2 series.

  • Merc1

    WOW they didn’t do squat about the back seat problem? What makes anyone think this car is going to do any better this time? I guess their thinking is that if we aim this little car at the other little cars it will fare better. PISS POOR strategy.


  • Rocket

    Interesting answer to the question: “How do we make sedans more appealing to slow the migration to crossovers?”

    Who in their right mind thinks making a car less space efficient is the right play here? One has to wonder if the brand is being intentionally sabotaged from within.

    • Merc1

      I’ve been saying that for a few months now. Someone at GM/Cadillac wants the brand to fold.


    • Ilbirs

      For me it’s no surprise why SUVs and crossovers are outselling conventional passenger cars, as they usually are shorter than a sedan on the same underpinnings and use to offer more room, specially considering that the bottom of the seats are more elevated than the ones seen on conventional cars. The advantage of this is the fact that these elevated seats doesn’t have to deal with the bulkiest part of the wheel wells, specially considering that current wheel wells are designed to fit 16 to 20 or 22 rims instead of what was usual for some decades (13 to 15, meaning less diameter of a tire-rim set even when the tires have a 60 to 70 side profile).
      The average customer did a trade-off when modern SUVs and crossovers arrived, giving up some gravity center, as current incarnations aren’t that bad handling vehicles, in exchange for this more room in a shorter length.
      If conventional cars at some time returned to the more rational shape they used to have (smaller rims leading to less bulky wheel wells and thus less length being taken by these parts), we would see the same length we see on a CT4 having a better use. Instead of making equations to fit huge rims, engineering to deliver the most room available for a given size. A CT4 made this way could even be way shorter than it’s now and offer almost the same interior volume. Smaller wheels would also lead to less unsprung weight and could even translate to better steering angles, something that would also reduce turning radius. The problem is that the average customer put in his/her head that huge rims are great, as they give some aesthetic effect of not having so much metal above the top point of the wheel on a conventional car. See that the proportions of a SUV or crossover fitted with a tire-rim set of the same size of the one seen on a conventional car more or less match the ones seen on past conventional cars with smaller wheels when considering how much of metal is above the wheels.

      • Alex

        I can buy the interior space explanation for the first-world markets where automakers don’t rip off customers. Here in Argentina car companies are shoving SUV’s down people’s throats so that they can sell a B-segment car at the price of a C-segment sedan. And B-segment SUVs are smaller than a C-segment sedan.

    • Cobrajet

      They think buyers of this, don’t care about rear seat space and those that do will get crossovers.



  • donald seymour

    Everyone on this post don’t forget that Cadillac’s marketing strategy is to have their sedan sized above their category, i.e the CT5 to the C and so on. So, the CT4 is sized perfectly above the A class.

    • Merc1

      Dumb strategy that has never worked.


      • donald seymour

        I don’t know Merc, I think this might work.

        • MarketAndChurch

          It’s Cadillac’s only choice really. ike Lincoln, the only option they have now for taking on the German big 3 is to be a value proposition and offer you a car similarly priced to the Germans, but with more interior room and better standard equipment/specs and features.

        • Merc1

          A warmed over ATS, in which they didn’t fix the flaws?

          Doubt it.


          • donald seymour

            Understood, but I still think this method might have a chance. Real deal.

      • Cobrajet

        They are admitting that are value brand.

        • Merc1

          Which is dumb because they’re supposed to be a luxury brand.


    • carlbolt

      Still the stupid “bigger is better” strategy, like the American homes, definitely bigger, but made of cheap stuff, can’t stand a strong wind.

      • donald seymour

        Bigger is better isn’t a stupid strategy, albeit that is true about some quality. But here’s the thing, people care perceived quantity, because in their minds it also a form of quality. People really do buy into this method.

  • carlbolt

    Given a certain wheelbase or footprint of the car GM is bound to give you smallest, the most cramping interior room for sure, That’s amazing!

  • carlbolt

    Wow! The car’s footprint increases a whopping 4.4 inch without even making the wheelbase one bit longer. What is this 4.4 inch for?

    • Loquacious Borborygmus

      The GM board’s ego?

  • Ilbirs

    Another practical class about why are current vehicles becoming bloated things compared to their more rational predecessors.

  • Alduin

    That rear end is hideous. The front is also way too busy. Bring back the Eldorado! I can’t imagine having to replace one headlight on this car looks like a PITA.

  • Robert

    I don’t think I could be more underwhelmed with this reveal. 😳. I swear it looks like they slapped Cadillac badges on Holden products. I guess Cadillac (and me) have to except they will always be tier 2 luxury because they just don’t have what it takes to elevate the brand to the next level. It’s really sad to me because Cadillac had a storied history to build from and GM’s ham-handed attempts to return it to luxury glory are truly laughable at this point.

  • StrangerGP

    The LED strip in the front continues to look ugly, hey Cadillac go and see new Peugeot’s how it’s done.

  • charlotteharry57

    Anyone over 6 feet tall, like me, will find this thing dreadful.

  • Mr_Fanta_Pants

    CT5 is Cadillacs 3 Series competitor.

    • Rocket

      No, it’s not. At 187″ long, the CT4 is actually a couple inches longer than the 3-Series sedan.

      • Mr_Fanta_Pants

        Size wise, yes, but didn’t Caddy say they’re pricing CT4 against A3/A Class and CT5 against 3 Series/C Class?

        • Rocket

          Yes, they did. And given the obvious lack of investment, they can afford to cut the price versus the ATS. But that doesn’t change the fact that it’s sized a full class larger. Again, size matters when it comes to cars. That will come into play as they attempt to get 3-Series shoppers into the larger CT5 as well.

    • Cobrajet

      NO. If you buy a Cadillac now, it because you are too poor to buy a BMW.

  • WalthamDan

    This vehicle is just a mess. I bet sales will be disappointing enough to cause Caddy to abandon sedans altogether in the future. The rear exterior design is horrible and it appears they learned nothing from all the previous interior space complaints.

    Sad to see the design path they have taken with their newest cars. Prepare the incentives.

    • matrem

      That was probably the point all along: to give them a reason to stop making sedans.

  • Paul

    Oh,the agony. I think this goes to prove that the “new” Cadillac just doesn’t get it because they’re repeating the same mistakes.

  • Marc Gruben


  • botornot387

    wow these are going to bomb so HARD. its not a horrible looking sedan, but it takes no leaps in terms of design. The front end almost looks alien like with those headlights on. This is DOA and will do nothing to change the tide for cadillac sedans.

  • SteersUright

    Dead On Arrival

  • Mr Nobody Important

    So the CT4 is not a direct replacement to the ATS. Is is going to compete in a smaller class of vehicles, and yet it is bigger on the outside with less interior room (fuc#ing looool), heavier (hahaha) and less horsepower than the ATS. Someone should go to Detroit and beat the living crap out of these GM clowns.

  • nastinupe

    People: What do we want? SUV’s, when do we want them? NOW!

    Cadillac. To People: Got ya!

    Cadillac: Internal Meeting: Lets makes more sedans.

    • Cobrajet

      They already introduced 3 new SUVs. Leave the sedans alone.

  • DetrinKD

    It’s the same car, reskinned. No matter how they twist and spin it. With such minuscule changes in dimensions, those changes are definitely from the new bumpers and probably new seats inside. The wheel base has not changed. To my eyes, the front fenders are the same as the ATS. Overall the car doesn’t carry the new Caddy look as well as the other CT’s and looks a little forced, at least in pictures. It may work in person.

  • Cobrajet

    It has less interior space because of thicker leather and headliner padding.

  • TheBelltower

    I like Cadillac’s latest visual design language… most of it anyway. But they’ve screwed the pooch with their latest sedans and SUVs. And as they’ve finally incorporated some of the beloved Elmiraj/Cien visual elements, they may have squandered this opportunity after all this time. The XT5 and XT6 were completely phoned-in averagemobiles. The XT4 is overpriced for it’s economy-car road presence. The CT4 and CT5 aren’t looking like the “standard of” anywhere. No boundaries have been pushed, the details are still horsey and unrefined, and these vehicles seem like more of the same. Though The CT6-V looks promising, no one will likely notice since the CT6 has already been shown as a poor alternative to the German flagships. Boo Cadillac. Boo!

  • Thando_Gqabaza

    This is the car GM should sell in Europe and build the brand …….. oh, wait, …..GM in its wisdom decided to pull out of Europe…..

  • johnls39 .

    Why the hell Cadillac wants to get back to the ’70s? The ’70s was the reason for the downfall for Cadillacs alongside the ’80s and ’90s to a certain degree.

  • johnls39 .

    The CT4-V is not a reskinned ATS. The only things carried over are the door handles, side mirrors and wheelbase and that is it. This car is on a stiffer platform. The weight of this vehicle is misleading because it does not start off in standard trim like the ATS was. The CT4-V may not be anyone’s cup of tea on here but should do fine for its segment. Although the visual shape looks similar to the ATS, this is a brand new vehicle on the second generation Alpha platform. The only things GM should done differently with the CT4 was upgrade the side mirror, door handles and add rear seat space by two inches. Although this is a brand new model, it comes across as a major refresh.

    It’ll be interesting what the standard CT4 will look like and what features it will pack when revealed this month in luxury and premium luxury trim.
